Free AI tools,
actually worth using.

These are the free AI tools the Institute of AI builds and runs in the UK: a growing set of public platforms for learning about AI, comparing the systems, and tracking where the field is going. They are made by a professional body rather than sold to you, which is exactly why they stay free and stay honest.

— What these are —

Public products, not a product pitch.

Most lists of free AI tools are affiliate pages in disguise, ranking whatever pays the most and sending you off to sign up somewhere. This one is different because the Institute of AI has nothing to sell you here. Every platform below is one of IoAI's own public products, built and maintained as part of its work as the UK's professional body for AI.

That independence is the whole point. There are no vendor deals shaping what the leaderboard says, no sponsors steering the trackers, and no account required to read the parts that are genuinely useful. You get tools for learning, comparing and staying current that are built to be trustworthy first and free as a matter of principle.

Open

AI news tracker

Open

Research

AI papers tracker

— No catch —

Free, and no upsell waiting at the end.

When something is free, the fair question is what it costs you elsewhere. Here the answer is nothing. These platforms are not a funnel and not a trial. They are free because a professional body should offer them that way, and because independence means nothing here is resold.

Free because a professional body should be

A professional body exists to raise the standard of a field, not to meter access to it. These platforms are funded as part of that remit and cost you nothing to use, now or later. There is no trial that quietly expires.

Nothing is resold to you

The Institute of AI is independent, with no vendor affiliations. The leaderboard, the trackers and the lessons carry no affiliate links and no paid placements. What you read is what IoAI judges to be true, not what a sponsor paid to promote.

No wall between you and the useful part

You can read the glossary, browse the leaderboard and follow the trackers without an account and without handing over your details first. The tools are open by default because a public resource that hides behind a form is not really public.

No upsell funnel dressed as a tool

These are finished products, not lead magnets engineered to nudge you toward a purchase. Accreditation and advisory exist alongside them and are named plainly where relevant, never smuggled in as the real point of a free page.

— Common questions —

Free AI tools in the UK, answered plainly.

Are these AI tools really free to use?+

Yes. Learn AI, the AI glossary, quick answers, the LLM Leaderboard, the Arena and the trending trackers are all free to use with no charge at any point. The Institute of AI runs paid accreditation and advisory work separately, but these public platforms are not gated behind it.

Do I need to create an account?+

You can read the glossary, browse the leaderboard and follow the trackers without signing up. Some interactive parts of Learn AI and the Arena work best when you are signed in, but nothing hides the useful content behind a form before you have seen it.

Who builds and pays for these tools?+

The Institute of AI, the UK's professional body for AI, builds and maintains them as its own public platforms. They are not client projects and carry no vendor affiliations, so what you see is IoAI's independent judgement rather than anything a sponsor paid to place.

How is the LLM Leaderboard scored?+

The LLM Leaderboard is community-scored, which keeps the ranking grounded in how the models actually perform for people using them rather than in vendor marketing. It sits alongside the Arena, where agentic systems compete directly, so you can weigh claims about capability against results.

Which tool should I start with?+

If you are learning, start with Learn AI and keep the glossary open beside it. If you are choosing a model, begin with the LLM Leaderboard. If you are trying to stay current, the AI news, papers and repositories trackers cover the ground for you without the noise.
