ChatGPT

OpenAI's flagship assistant, now running on the GPT-5.6 model family

ChatGPT remains the AI chatbot most people mean when they say "AI" — helping with writing, coding, research, brainstorming, image generation and voice conversation, used by hundreds of millions of people weekly. Its underlying model has moved well past the GPT-4o generation many older reviews still describe: as of July 9, 2026, ChatGPT runs on the GPT-5.6 family, with three named tiers — Sol (frontier reasoning), Terra (balanced) and Luna (fast, budget) — rather than a single flagship model. The subscription lineup expanded meaningfully too. Free now gives unlimited text chat on GPT-5.6 Luna (with ads in the US, rolling out from August 2026) alongside capped image, voice and file uploads. A new Go tier at $8/month, launched globally in January 2026, raises those caps without unlocking Agent mode or Deep Research. Plus stays at its familiar $20/month, now including the full GPT-5.6 family, Agent mode, and a mix of full and lightweight Deep Research tasks. Pro splits into two usage-based tiers — $100/month (5x Plus usage) and $200/month (20x Plus usage, largest limits, priority compute) — closing the old 10x jump from $20 straight to $200. Business and Enterprise remain built for organizations, with Business running roughly $20-25/seat/month (2-seat minimum) and Enterprise custom-quoted, commonly cited in the $45-75/seat/month range for large deployments with SSO, dedicated data residency and compliance paperwork. For most individual users doing regular work, Plus at $20/month remains the practical sweet spot; light or occasional users can now genuinely get by on the improved Free tier, and heavy professional users have a real $100 middle ground before jumping to the top Pro tier.

Claude

Trending Featured

Anthropic's assistant, now on the Sonnet 5 and Opus 5 generation

Claude remains known for nuanced reasoning, careful writing and strong coding performance, built by Anthropic around a Constitutional AI safety approach. The model lineup has moved well past the 200K-context generation many older descriptions still reference: current models include Claude Sonnet 5 (released June 30, 2026) and Claude Opus 5 (released July 24, 2026), both supporting up to a 1-million-token context window on qualifying plans — a meaningful jump for anyone working with large documents or codebases. Subscription tiers now include Free, Pro at $20/month (the familiar entry point, includes Claude Code), and two Max tiers — $100/month (5x Pro usage) and $200/month (20x Pro usage) — for people who exhaust Pro's session and weekly limits regularly. Pro, Max and Team plans share a session limit (resets every five hours) plus a weekly limit across all models, with both pools shared between the Claude apps and Claude Code specifically. On the API side, current per-million-token rates run Haiku 4.5 at $1/$5 (input/output), Sonnet 5 at $2/$10, and Opus 5 at $5/$25 — Opus notably cheaper than the prior Opus 4.8 generation. Claude Code's rapid growth (reportedly $2.5 billion in annualized revenue) reflects how central coding has become to Claude's use case, and Anthropic closed a $30 billion Series G funding round in February 2026 at a $380 billion valuation, with a potential IPO discussed as early as October 2026. For most individual users, Pro at $20/month remains the right starting point; developers and teams doing sustained heavy coding work are the ones who typically outgrow it into Max.

Google Gemini

Google's flagship AI, now on the Gemini 3.1 Pro generation

Gemini is Google's AI assistant, deeply woven into Workspace, Search and Android — and its model lineup has moved well past the Gemini 1.5 generation that older descriptions still reference. The current flagship is Gemini 3.1 Pro (launched February 19, 2026), alongside a family of Flash models (3.5, 3.6, 3.7) tuned for speed and cost, all supporting large context windows suited to document-heavy and agentic work. Google tightened its free tier meaningfully on April 1, 2026: Pro-tier models (3.1 Pro, 3 Pro, and legacy 2.5 Pro) are now paid-only through the API, though Google AI Studio still offers the most generous free access among major providers for Flash and Flash-Lite models, with real models and no credit card required — just reduced daily quotas. On the consumer side, Gemini Advanced remains bundled with Google One's 2TB storage tier, priced around $19.99-20/month, which makes it effectively cheaper than a standalone subscription for anyone already paying for Google storage. API pricing for Gemini 3.1 Pro runs $2/$12 per million input/output tokens for prompts under 200K tokens (doubling above that threshold), while Gemini 3.6 Flash runs a competitive $1.50/$7.50 — both undercutting comparable tiers from OpenAI and Anthropic on raw price, a genuine and consistent Google differentiator. New agentic tools like Gemini Code Assist and Gemini CLI (both new in 2026) add thinking-token costs that can compound quickly during active coding sessions, a real budgeting consideration for developers using them at volume. For everyday productivity tightly integrated with Gmail, Docs and Search, Gemini remains a strong default, especially for anyone already inside the Google ecosystem.

Weglot

The fastest way to add multilingual pages to an existing website

Weglot solves website translation with minimal engineering effort: install a snippet or platform plugin, connect your domain, and translated versions of every page go live on SEO-friendly subdirectories (like yoursite.com/fr/) within minutes — no rebuilding your site's content architecture required. Under the hood, it routes machine translation through DeepL, Google Translate, Microsoft Translator or Yandex, then lets you manually edit any translation directly from a visual dashboard, with a glossary feature for locking in brand names and product terminology so automated translation doesn't mangle them. It's built specifically for website translation rather than broader document or app-string localization — a meaningfully narrower scope than a full translation management system like Smartcat, but that focus is exactly why setup takes minutes rather than a real implementation project. It works across marketing sites, ecommerce stores and online courses, translating dynamically loaded content as well as static pages, which is a common failure point for simpler translation-proxy approaches. Pricing starts with a genuinely free tier (2,000 translated words, one language, one project) and paid plans from $17/month scaling by word volume and number of languages. The most common complaint across reviews, echoed consistently: the exact pricing structure (calculated per word, with some ambiguity around whether page loads factor in) is harder to predict upfront than a flat per-seat SaaS price, worth clarifying with a support conversation before committing to a plan sized for your actual site's word count and traffic.

Crowdin

AI-assisted localization built for software teams shipping products in 50+ languages at once

Crowdin is built specifically for a problem general translation tools like [DeepL](/tools/deepl) in our [AI Translation Tools category](/category/ai-translation-tools) don't fully solve: localizing an actual software product — apps, websites, games — where strings live inside code, need context screenshots to translate accurately, and require ongoing updates as the product itself changes, not a one-time document translation. Its AI pre-translation feature uses machine translation combined with translation memory (previously approved translations for your specific product) to draft new strings automatically, which human translators or reviewers then refine — a meaningfully faster starting point than translating from scratch every time new text ships. In-context screenshots let translators see exactly where a string appears in the actual interface, catching mistranslations that happen when text is translated in isolation without visual context. Integrations with GitHub, GitLab and most major development workflows mean new strings sync automatically for translation as developers ship code, keeping localization continuously up to date rather than batched into occasional, disruptive translation sprints. A free tier covers small open-source projects; paid plans, starting around $50/month, scale with the number of strings and languages, aimed at software teams rather than individual document translation needs.

Phrase

An enterprise localization platform combining AI translation, quality checks and a translator marketplace

Phrase (formerly known separately as Phrase and Memsource before merging) operates as a full localization management platform rather than a single translation tool, combining AI-powered machine translation, automated quality assurance checks, and access to a marketplace of professional human translators and agencies — covering the entire localization workflow from initial draft through final human review and delivery. Its AI layer can automatically select the best-performing machine translation engine for a given language pair and content type from multiple providers (including its own and major third-party engines), rather than locking you into one translation model regardless of fit — a meaningfully different approach from [Crowdin](/tools/crowdin) in our [AI Translation Tools category](/category/ai-translation-tools), which centers more on developer-workflow integration specifically. Automated QA checks catch formatting errors, inconsistent terminology and missing placeholders before content ships, reducing the manual review burden on human linguists. It's positioned for larger organizations and language service providers managing complex, high-volume localization across many languages and content types (software, marketing, legal, documentation), with enterprise-tiered pricing based on word volume and feature modules rather than a simple flat subscription. A free trial is available; published starting prices begin around $27/month for smaller teams, scaling to custom enterprise quotes for larger localization operations.

Smartcat

AI translation plus a marketplace of 500,000+ human linguists

Smartcat blends AI-driven machine translation with a genuine marketplace of professional human translators — reportedly over 500,000 linguists — inside one unified platform, aimed at businesses that need flexibility to combine fast automated translation with expert human review depending on how much a given piece of content actually matters. Its newer AI Agents extend beyond plain text into images, video and documents within a single workflow, with the agents themselves improving over time as team members or marketplace linguists make edits — each correction feeding back into brand glossaries and translation memory. Its free tier is genuinely one of the most generous in the category: 15,000 words a month with full translation management system (TMS) features included, not a stripped-down trial — making it the best free starting point specifically for teams managing ongoing localization projects rather than one-off document translations. Beyond the free tier, pricing scales with word volume, marketplace linguist usage and which AI engines you route through, positioned well below enterprise players like Smartling ($50,000-200,000+/year) or Phrase ($1,245+/month) for mid-market teams that don't need that level of enterprise integration depth. The honest trade-off, per multiple comparative reviews: website integration specifically is more technical than a purpose-built tool like Weglot, and the interface can feel dense for a first-time user managing document-heavy or mixed-format localization needs. For teams needing flexibility across content types — documents, marketing copy, occasional website content, training materials — combined with the option to tap human expert review on higher-stakes content, it remains a strong mid-market pick; for website-translation specifically as the only need, Weglot's narrower focus is faster to set up.

Lilt

Enterprise adaptive translation with custom pricing - not a self-serve app for small teams

Lilt is an enterprise adaptive machine translation platform, not a consumer translator and not a cheap self-serve plan for freelancers. The first questions people ask on search are usually about pricing, whether it fits a small business, and how it handles terminology. Short answers: there is no public rate card (sales-quoted only), it is built for large localization programs rather than solo use, and its main technical edge is Contextual AI that learns from human corrections in session, which helps brand voice and glossary-heavy content. Rather than a static model that ignores feedback until a later retrain, Lilt adjusts word choice, grammar and style as translators correct output, and those adjustments often apply in the same session. That loop is why teams with strict terminology, regulated language or a fixed brand voice evaluate it against generic engines. April 2026 added dozens of languages and an autonomous LILT Assist agent; May 2026 added automated PDF workflows that try to keep original layouts. Security features such as SSL, AES-256 and role-based access matter for government and defense-style workflows more than for a one-person shop. If you need website widgets, a published monthly price or a free tier for a few documents a week, tools like [DeepL](/tools/deepl), [Weglot](/tools/weglot) or [Smartcat](/tools/smartcat) are usually the better first look. Choose Lilt when you already run (or are buying) a governed localization program and can complete a vendor evaluation, not when you only need occasional document translation.

Unbabel

AI + human hybrid translation for customer support, now under TransPerfect

Unbabel pioneered what it calls "Language Operations" (LangOps): blending AI machine translation with a network of human editors to deliver customer support translation that's both fast and genuinely reliable, aimed at large-scale multilingual support operations where AI-only translation risks embarrassing or costly errors. Clients including Microsoft, Booking.com, Udemy and Panasonic have used it to run customer support and chat translation across multiple languages without staffing native speakers for every language pair. Its research team built TowerLLM (its flagship open-weight multilingual model family) and contributed to widely-used machine translation evaluation metrics like COMET, alongside 2025 releases of TOWER+ (open-weight multilingual LLMs) and EuroVLM (multilingual vision-language models) — genuine technical contributions to the broader translation field, not just a product wrapper. What's essential to know before evaluating Unbabel in 2026: it was acquired by TransPerfect in August 2025, following a reported roughly 50% revenue decline over the preceding year, in a deal described by reporting as a "relatively low value" sale resulting in a total loss for many earlier investors. TransPerfect has stated integration will largely mean "business as usual" for existing customers, planning to fold TowerLLM into its own GlobalLink ecosystem while expanding language pairs and industry-specific fine-tuning. Pricing remains pay-as-you-go/custom rather than published flat tiers. For enterprise customer support teams specifically needing the AI-plus-human-review hybrid model at scale, Unbabel (now under TransPerfect's larger resources) remains a credible option — though the ownership change and preceding financial struggles are worth factoring into any long-term vendor evaluation.

HeyGen

Trending

AI avatars for marketing, training and sales video

HeyGen turns a script into a video of a presenter speaking it — either a stock avatar, a photo-based avatar built from your own image, or a "Digital Twin" trained to closely match a specific person. Its newest engine, Avatar IV, reads the emotional register of a script and generates matching micro-expressions, head movement and timing-aware hand gestures, which is why independent reviewers consistently rate its avatar realism as the strongest in the category (G2 scores it 9.2/10 on avatar quality specifically). Beyond avatars, it includes lip-synced video translation into 175+ languages, voice cloning, and a Video Agent that can assemble a complete video from a single prompt. The part that catches people off guard is the credit system underneath the subscription price. Plans come with a monthly Premium Credit allowance, but different content types burn credits at wildly different rates — Avatar IV content can use up an entry-level plan's allowance in a fraction of the video minutes the plan technically permits. A Creator plan's 200 monthly credits, for instance, covers only around 10 minutes of premium Avatar IV video, not the 30-minute cap the plan advertises for standard content. Pricing starts at $29/month for Creator (unlimited standard videos, 700+ stock avatars, voice cloning, 175+ languages), scaling to Pro at $99/month for heavier credit allocations and 4K export, and Business at $149/month plus $20/seat for team collaboration and SSO. It's best suited to marketing, sales and L&D teams producing repeatable talking-head content — localized product videos, training modules, personalized outreach — where the credit cost is offset by not booking a studio and on-camera talent every time.

ElevenLabs

Trending

The most realistic AI voice platform, now valued at $11 billion

ElevenLabs remains the reference point for realistic AI voice generation — text-to-speech, voice cloning, dubbing and conversational AI agents — founded in 2022 by Piotr Dąbkowski and Mati Staniszewski, two Polish engineers frustrated by poor-quality film dubbing. The company's growth since has been extraordinary: annual recurring revenue crossed $500 million in the first four months of 2026 after ending 2025 at $350 million, and a $500 million Series D round in February 2026 pushed its valuation to $11 billion, more than tripling in twelve months. Pricing runs on a unified credit system across seven tiers: Free (10,000 credits/month, roughly 10 minutes of speech), Starter ($5-6/month, 30,000 credits), Creator ($11-22/month depending on promotional pricing, 100,000 credits, professional voice cloning), Pro ($99/month, 500,000 credits, 44.1kHz production-quality API audio), Scale ($299/month) and Business ($990-1,320/month), with custom Enterprise above that. One credit is roughly one character of text-to-speech using the standard Multilingual v2 model, while the faster Flash and Turbo models run at 0.5 credits per character — effectively doubling output for the same allowance. Beyond core voice generation, ElevenLabs has expanded into a genuinely broad platform: Eleven Music (community has created 14 million songs, with a creator payout marketplace), a voice-actor creator economy that has paid out over $22 million to 10,400+ creators, and enterprise conversational AI agents — Klarna's February 2026 ElevenLabs-powered phone support deployment for 35 million US customers reported up to 10x faster resolutions. With 41% of Fortune 500 companies using the platform and clients spanning Disney, Nvidia, Meta, Washington Post and HarperCollins, it has moved well beyond a simple text-to-speech tool into comprehensive voice AI infrastructure. For anyone prioritizing raw voice realism, ElevenLabs remains the benchmark competitors are measured against.

Rask AI

AI video translation, dubbing and lip-sync in 135+ languages

Rask AI is a video and audio localization platform. You upload a video, and it transcribes the speech, translates it into more than 135 languages, dubs it with an AI voice, offers voice cloning in about 32 languages and can add lip-sync and subtitles. It is used by creators, e-learning teams, marketers and media companies that want to reach new audiences without re-recording. Pricing is based on minutes of video processed. Reviewers verifying Rask's pricing page report a free trial of 3 minutes, Creator at $60 per month ($33 billed annually) for 25 minutes, Creator Pro at $150 per month ($78 annual) for 100 minutes and Business at about $750 per month, with custom Enterprise plans. Creator and Creator Pro do not allow buying extra minutes, Business overage is $3 per minute, annual plans roll over unused minutes and enhanced lip-sync uses three usage minutes per video minute. The trade-offs are a high entry price for 25 minutes, no permanent free plan and costs that rise quickly for long or lip-synced videos. Confirm current plans on Rask's pricing page.
