In AI tooling, "free" almost always means "runs on your computer"
Search for free AI tools and you will get lists of hundreds. Open any of them and most entries have a pricing page.
The word is doing a lot of work. So we counted.
What the catalogue actually contains
Every listing here records how the maker charges, taken from the maker's own pricing page rather than guessed at. As of today, across the 155 tools published:
| Model | Count |
|---|---|
| Freemium — free tier, paid plans above it | 118 |
| Subscription | 21 |
| Contact us for a price | 7 |
| Free — the maker charges nothing for the product | 6 |
| Paid outright | 3 |
Six. And 118 that the internet will cheerfully file under "free".
You can check this yourself: the free ones are on one page, and every listing states its model.
The six have something in common
| Tool | Open source | Where it runs |
|---|---|---|
| Aider | Yes | Your terminal |
| Cline | Yes | Your editor |
| ComfyUI | Yes | Your machine |
| Ollama | Yes | Your machine |
| LM Studio | No | Your machine |
| EasyInvoicePDF | Yes | Your browser |
Five of six are open source. All six run on hardware you already pay for.
That is the whole mechanism. A tool that runs on somebody else's servers costs that somebody money every time you use it, and inference is not cheap. There are only three ways that ends: you pay, an investor pays for a while, or the free tier is small enough to function as an advert. A tool that runs on your machine has none of that pressure, because the hosting bill is your electricity bill.
So "free" in this category is less a business decision than a deployment one. If it runs locally it can afford to be free. If it runs in a browser tab against a GPU somewhere, it cannot, whatever the pricing page says today.
Open source is not the same as free, either
Fourteen of our listings are open source and freemium. The source is published, and the hosted version is the product — Zed, Stability AI, Black Forest Labs, LlamaIndex, CrewAI among them.
That is a legitimate and increasingly common model, and it is worth understanding before you pick: you can self-host and pay nothing but your own time, or you can pay them to run it. What you should not assume is that an open-source badge means the convenient version is free.
How to read a free tier before you commit
Find the limit, not the price. Every freemium tool has a number that ends the free part: messages per month, images per day, seats, projects. That number is the actual offer. If the pricing page does not state one, that is itself the answer.
Check what happens at the wall. Does it stop, queue you, or start charging? The last one is worth knowing before you build a workflow on it.
Ask whether your data comes back out. Free tiers are where export gets restricted. A tool you cannot leave is not free, it is deferred.
For anything you will run daily, look local first. The six above are not compromises — Ollama and ComfyUI are what a lot of paid products are wrapping. Local costs you setup time and a machine that gets warm, and nothing else.
Why we counted
We are a directory, and directories have an obvious incentive to call as much as possible free, because "500 free AI tools" is a better headline than "six".
We would rather the number be useful. Every listing here states its pricing model on the page, taken from the maker's own site, and the free page says plainly that 118 others run a free tier alongside paid plans rather than folding them all into one count.
If you make one of these and the model on your listing is wrong, tell us — or submit the tool and set it yourself. Listing is free and asks for nothing in return.
