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.

DeepSeek

Trending

Open-source reasoning AI at a fraction of the cost

DeepSeek made its name by shipping reasoning models that compete with the top US labs while charging a small fraction of the price on the API side — and giving away the consumer chat product entirely for free, with no subscription tier at all. The web and mobile chat at chat.deepseek.com runs the V4 Flash model by default, with a DeepThink toggle that switches into a slower, more deliberate reasoning mode for harder problems. On the developer side, the API is priced aggressively: V4 Flash costs a small fraction of a cent per thousand tokens, with automatic prompt caching that cuts costs further on repeated context, and a larger V4 Pro tier for the hardest workloads at roughly three times the price. Both models share a 1-million-token context window. For teams doing high-volume work — summarisation, classification, RAG pipelines — the cost difference compared to a frontier US model can be dramatic. The trade-off worth knowing about upfront: DeepSeek's infrastructure is operated from mainland China, and the consumer chat product is subject to Chinese data-handling regulations, which matters if you're sending sensitive personal or business information through it. It's a fine, genuinely capable tool for personal experimentation and cost-sensitive API work — just go in aware of where the data lives.

Kimi

Long-context AI assistant built for deep documents

Kimi, built by Moonshot AI, made its name with extremely long context handling — it can read entire books, long financial filings or hundreds of pages of research in a single conversation and keep track of details throughout. More recent Kimi releases added strong agentic behaviour: the assistant can browse the web, run multi-step research, execute code and produce structured reports. Moonshot also publishes open-weight Kimi models, which have become popular in the open-source community for coding and reasoning workloads. For analysts, lawyers, researchers and anyone whose work is document-heavy, Kimi is one of the most practical free assistants available, especially when a task involves synthesising many long files at once.

Qwen Chat

Alibaba's free frontier-class multimodal assistant

Qwen Chat is the consumer interface for Alibaba Cloud's Qwen model family. It offers text chat, vision understanding, document analysis, coding help, image generation and video generation — most of it free, which makes it one of the most generous frontier-class assistants available. The underlying Qwen models are also released as open weights, so developers can self-host the same architecture they use in the chat app, and many open-source projects fine-tune Qwen for domain-specific work. That dual open/hosted strategy has made Qwen a default choice for teams that want capability without vendor lock-in. Qwen Chat supports very long context windows, multilingual conversation with particularly strong Chinese and English performance, web search grounding and an artifacts-style preview for generated code.

Replika

The AI companion app with 30M+ users, built for ongoing relationship and emotional connection, not tasks

Replika takes a fundamentally different approach from a productivity-focused chatbot like [ChatGPT](/tools/chatgpt) in our [AI Chatbots category](/category/ai-chatbots): it's built specifically as a long-term AI companion, designed to remember your conversations, develop a consistent personality over time, and provide ongoing emotional support and connection rather than answering discrete queries or completing tasks. Users customize their Replika's appearance, personality traits and the nature of the relationship (friend, romantic partner, mentor), and the AI adapts its responses based on accumulated conversation history. Launched in 2017 — years before the current wave of AI companion apps — it has grown to over 30 million users and remains one of the most recognized names in the category, though it has also faced real, documented controversy: a 2023 Italian data-privacy ban (since partially resolved), removal of certain romantic/erotic roleplay features in 2023 that triggered significant user backlash, and ongoing research and journalism scrutiny around emotional dependency risks for vulnerable users, particularly around grief, loneliness and attachment. A free tier covers basic conversation; Replika Pro, around $19.99/month or roughly $69.99/year, unlocks deeper personality customization, additional conversation modes and voice calling. Given the documented concerns, it's worth approaching deliberately rather than as a replacement for human connection or professional mental health support — the company itself has added in-app resources directing users toward crisis support where relevant.

Character.AI

Trending

Chat with millions of AI characters

Character.AI is less a chatbot and more a platform: over 10 million user-created characters, from original companions to fictional and historical personas, that anyone can talk to or build using the in-app Character Editor. It's built around roleplay, storytelling and companionship rather than factual accuracy, and that distinction matters — this is not the tool to reach for when you need a reliable answer, but it's genuinely good at sustained, in-character creative conversation. The free tier is unusually generous: unlimited messaging and full access to character creation, though you'll hit queueing during peak hours and, as of 2026, ads that appear mid-conversation. The optional c.ai+ subscription doesn't unlock a smarter model — the underlying AI is identical on both tiers — it buys priority access, faster responses, unlimited voice calls and no ads, plus early access to newer features like the Imagine Gallery image generator. With 20 million monthly users averaging around 75 minutes a day on the platform, engagement is unusually high for a consumer AI product, which is also why the platform has introduced stricter teen-safety measures over the past year. It's worth knowing this is a creative and companionship tool first, not a research or productivity assistant.

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.

Microsoft Copilot

Featured

Microsoft's AI companion across Windows, Edge and Microsoft 365

Microsoft Copilot is the assistant Microsoft has woven through Windows 11, Edge, Bing and the Microsoft 365 apps. In the consumer app it answers questions, drafts text, analyses images and generates pictures; inside Word, Excel, PowerPoint, Outlook and Teams it works on the documents and mailboxes you already own. What separates Copilot from a standalone chatbot is grounding in Microsoft Graph: with a Microsoft 365 licence it can summarise a Teams meeting you missed, pull figures out of a workbook, rewrite a deck's speaker notes or triage an overflowing inbox, all with links back to the underlying files. Copilot Vision can also look at your screen or a browser tab and talk you through what is on it. For organisations already standardised on Microsoft, the commercial data protection promise, tenant-level admin controls and per-seat licensing make Copilot the path of least resistance for rolling AI out to non-technical staff.

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.

Meta AI

Meta's Llama-powered assistant across its apps

Meta AI is the assistant built into WhatsApp, Instagram, Messenger, Facebook and the standalone meta.ai app, running on Meta's Llama models alongside a newer proprietary model called Muse Spark introduced in 2026. Its biggest advantage is sheer reach — it's embedded directly into apps that billions of people already use daily, so there's no separate download or account needed for most people to try it. A meaningful change happened on June 10, 2026: Meta began charging for some of what used to be entirely free. The base assistant remains free with daily message caps, but longer context, file uploads, long-document summaries, voice memory and agentic task execution moved behind a new subscription, Meta One Plus, at $14.99/month. Meta cited rising hosting costs for its larger models as the reason. This is worth knowing if you'd read older reviews describing Meta AI as unconditionally free — that's no longer accurate. Separately from the consumer assistant, Meta also publishes Llama as an open-weight model family that developers can download, fine-tune and self-host under a mostly permissive license (with some restrictions for very large companies and, for Llama 4's multimodal features, for companies established in the EU). For most everyday users, though, Meta AI is simply the free-ish chatbot that's already sitting inside apps they open every day.

Grok

xAI's assistant, now on Grok 4.6 with a standalone SuperGrok tier

Grok is xAI's conversational AI, distinguished by real-time access to X (formerly Twitter) data, a blunter tone than most competitors, and image and video generation via Grok Imagine. Its current flagship API model is Grok 4.6, released August 12, 2026, with older cheaper model IDs (Grok 4, Grok 4.1, Grok 4-fast) retired on May 15, 2026 and now silently redirecting to Grok 4.3 pricing — worth knowing if you built cost estimates on the old, cheaper rates. Access splits across two paths that often confuse people researching Grok: the standalone grok.com app (Free, SuperGrok Lite $10/month, SuperGrok $30/month, SuperGrok Heavy $300/month) and the X-bundled path (X Premium $8/month, X Premium+ $40/month), each with different model access and limits. The commonly cited "$8/month" figure for Grok refers to X Premium's bundled access, not a full standalone Grok subscription — SuperGrok at $30/month is the more accurate comparison point against ChatGPT Plus or Claude Pro. Paid plans now share one weekly usage pool spendable across Chat, Imagine, Voice and Build, replacing the older per-2-hour prompt caps retired in June 2026. On the API side, Grok 4.6 runs $2/M input and $6/M output tokens under a 200K-token threshold (doubling above it), with an 85% cache discount bringing cached input down to $0.30/M. For users who want an AI assistant with genuine real-time social-media awareness and a less filtered tone, Grok remains distinctive; for straightforward general assistant use without X integration, ChatGPT or Claude typically offer more polished, mature experiences.
