ChatGPT: best overall
By OpenAI
Our all-round ChatGPT pick includes search, file analysis, image creation and custom GPTs. Plain conversation has no published cap, so it's the one to keep open all day.
What's free
- Everyday text chat, described by OpenAI as unlimited within abuse safeguards
- Web search, file and image uploads, and data analysis
- Image creation inside the chat
- Use of existing custom GPTs
- 500 MB of library storage
Free-plan limits

- OpenAI doesn't publish fixed daily numbers for those tool limits
- Ads may appear for free users in some countries
Google Gemini: best for research
By Google
Gemini's free tier includes Deep Research, which writes a sourced report from dozens of web pages. That's a feature other companies charge for, and it makes Gemini the best free AI for homework and market research.
What's free
- Chat with Google's Flash-class models
- Image generation and editing with Nano Banana 2
- Deep Research reports, Canvas and custom Gems
- Gemini Live voice conversations
- Uses your standard 15 GB Google account storage
Free-plan limits
- Lower usage limits than paid plans; Google doesn't publish exact prompt counts
- Video generation in the Gemini app needs a paid plan
- Account, age, country and language restrictions apply
Claude: best for writing
By Anthropic
We prefer Claude for drafting and long-document work; that's an editorial choice, not a measured writing-quality result. The trade-off is a five-hour usage window that heavy users will notice.
What's free
- Chat on web, desktop and mobile
- Web search, memory and file creation
- Code execution and Artifacts
- Connections to apps and tools
Free-plan limits
- Pricing cards list five-hour and weekly usage limits; help wording differs, so follow your account notice
- Claude Code and some workflow features are paid only
DeepSeek: free coding chat

What's free
- Free consumer chat, per DeepSeek's app announcement
- Web search and a step-by-step reasoning mode (DeepThink)
- File upload with text extraction
- Open-weight models you can also run yourself
Free-plan limits
- No published usage numbers; the app can slow down at busy times
- Data is processed under DeepSeek's privacy policy in China, which some employers restrict
Perplexity: best for cited answers
By Perplexity AI
Perplexity is closer to a search engine than a chatbot. Every answer links to its sources, which is the quickest way to check whether an AI is right.
What's free
- AI search answers with numbered citations
- Access to top AI models with limited weekly usage, per Perplexity's pricing FAQ
- Follow-up questions in a thread
Free-plan limits
- Usage is limited, with no published query count

Microsoft Copilot: best for windows
By Microsoft
Copilot is already on most Windows PCs and in Edge. It's a capable free AI assistant, though Microsoft is vague about free limits.
What's free
- Chat with a personal Microsoft account

- Image creation and AI-generated audio
Free-plan limits
- Paid plans get higher usage for chat, images and audio; free quotas aren't published

Grok's free tier is limited but handy for questions about what people are posting on X right now.

- Chat at $0/month
- A limited number of agent requests
Free-plan limits
- Request limits aren't published as numbers
- Faster responses and larger usage pools are paid
How to choose a free AI chatbot
- What the free plan includes
- Look past 'free' to the tools: web search, file uploads, image creation and voice are not all included everywhere.
- How limits work
- Some cap by message, some by time window, some by tool. ChatGPT limits tools; Claude limits by five-hour window.
- Where your data goes
- Check whether chats train the model and which country processes them. Most apps let you opt out in settings.
- Whether you can check answers
- Chatbots make mistakes. Tools that cite sources, like Perplexity and Gemini Deep Research, make checking quick.
