Best Free AI Tools in 2027
The best free AI tools in 2027 are the ten below, and together they cover writing, research, design, images, video and coding without a single subscription. A free tier is a plan that costs $0 with no time limit, usually with a usage cap, and it is different from a free trial, which ends after a set number of days. The honest catch is the cap: every free plan in this list has one, and this guide states each limit plainly so you can tell in two minutes whether a tool will actually carry your workload or only let you try it.

All prices are US list prices before tax, checked in November 2026. A free tier needs no credit card on any tool in this list, but several paid upgrades do ask for one, so check before you upgrade.
1. ChatGPT free tier
ChatGPT's free plan costs $0 and is still the most useful free AI tool for most people, because it drafts emails, explains ideas, summarises articles and writes first drafts of almost anything. The limit is a daily usage cap on messages and on the more capable models, and OpenAI does not publish the exact number, so heavy users will hit a wall without warning and be asked to wait or upgrade. Plus costs $20 a month for higher limits.
2. Claude free tier
Claude's free plan costs $0 and is the best free option for long documents, because it handles big files and careful drafting better than most free chatbots. The usage allowance is a baseline amount that resets every five hours, and Pro at $20 a month gives at least five times that usage. The free tier does not include Claude Code. Use it free for summarising long reports, drafting careful replies and working through a document section by section.
3. Gemini free tier
Gemini's free plan costs $0 with any Google account and is the best free AI tool for people who already live in Gmail, Docs and Drive. Free accounts get the Flash-Lite model through automatic model selection, 15 GB of storage, image generation, Deep Research, Gemini Live and Canvas, with standard usage limits. The catch, covered in our earlier piece on the Gemini free tier Flash-Lite downgrade, is that heavy prompts drop to the lighter model, so long or complex work slows down. Google AI Plus costs $4.99 a month and doubles the allowance, while Pro costs $19.99 a month.

4. Canva free
Canva's free plan costs $0 with no time limit and is the most generous free design tool in this list. It includes more than 1.6 million templates, millions of free assets, 5 GB of storage and a monthly allowance of AI uses, reported as up to 200 Standard AI uses or 20 Premium AI uses a month. The limits are real: no background remover, no resizing, no premium stock and only one brand kit. Pro costs $18 a month and adds those features plus ten times the AI allowance.
5. Grammarly free
Grammarly's free plan costs $0 and catches spelling mistakes, basic grammar errors and punctuation slips across the browser, Docs and Word. It also includes tone detection and 100 AI prompts a month. What it does not include is the part most people want: full-sentence rewrites, plagiarism detection and advanced clarity suggestions, which need Pro at $12 a month on annual billing, or $30 billed monthly.
6. Perplexity free
Perplexity's free plan costs $0 and is the best free tool for research, because every answer comes with cited sources you can click and check. The limits are tight and clearly published: 3 Pro Searches a day and 1 Research query a month, with basic models and limited daily usage beyond that. Pro costs $20 a month, or $17 a month billed annually, and adds extended research, a model picker and file analysis.
7. Leonardo AI free tier
Leonardo AI's free plan costs $0 and gives 150 Fast Tokens a day, which covers roughly ten to fifteen standard images depending on size and settings. The limits matter: free accounts can only use the Auto model, not the 80-plus other models, and everything created on the free plan is public, so other users can view it. A November 2026 hands-on test also reported that clicking download on a free creation opened the upgrade page, so treat downloading as a possible paywall and test it yourself before relying on it. Essential costs $12 a month, or $10 billed annually, and adds private creations and all models.

8. CapCut free
CapCut's free plan costs $0 and covers basic video editing with free templates on web, desktop and mobile, which is enough for short social videos. The limits are clear: no cloud storage, since CapCut ended its free storage allowance in August 2024, no 4K or 60 frames-per-second export, and some advanced templates, effects and stock elements add a watermark. New accounts also get 200 one-time welcome credits. Pro costs $19.99 a month, or $179.99 a year, and adds 1,200 AI credits a month and 1 TB of storage.
9. Hugging Face free
Hugging Face is the home of open machine learning, with more than two million public models and hundreds of thousands of datasets that anyone can browse and use for free. The free account costs $0 and includes public models and datasets, static Spaces and basic CPU hardware, plus a small ZeroGPU allowance reported at five minutes a day. The important change is that free accounts no longer get included inference credits, so running models through the paid inference service needs credits bought separately or a PRO plan at $9 a month, which includes $2 of monthly compute credits.
10. Microsoft Copilot free
Microsoft Copilot's free tier costs $0 with a signed-in Microsoft account and works on the web, in Windows, in Edge and on mobile. It covers web chat, cited answers, image generation, file uploads and voice, with limited usage that Microsoft does not publish as a number. Copilot Pro costs $20 a month and adds priority model access and AI inside Word, Excel, PowerPoint and Outlook, but it needs a Microsoft 365 Personal or Family subscription underneath. Note that Microsoft has been folding standalone Copilot Pro into Microsoft 365 Premium at $19.99 a month, and existing Pro subscribers keep the old plan until support ends on 1 August 2026, according to third-party reporting.

How to use free tiers without getting stuck
Three rules keep free tools useful. First, read the limit before you build a habit around a tool, because a cap you discover mid-project costs more than a subscription would have. Related: AI tools for real estate agents.
Key Takeaways
- Every free tier in this list has a published or practical limit; none of them is unlimited, and none should be called free forever.
- ChatGPT, Claude, Gemini and Copilot all offer genuinely useful free chat, with daily or five-hour usage caps.
- Perplexity free is the best free research tool, but it only allows 3 Pro Searches a day.
- Leonardo free gives 150 tokens a day for images, but creations are public and limited to one model.
- Hugging Face free is best for learning open models; running them at scale needs paid credits.
Conclusion
The best free AI tools in 2027 let you write, research, design, edit video and explore open models for $0, as long as you respect their limits. Start with ChatGPT or Claude for writing, Perplexity for research, Canva for design and CapCut for video, and add a paid plan only for the single tool whose limit you hit every day.
