The honest comparison
Hearth vs ChatGPT, Gemini & Claude
If you want a private, offline, free alternative to the big cloud AIs — one that runs on your own computer and never sends your words anywhere — here's the honest picture of what's different, and when each one is the right call.
The short version: ChatGPT, Gemini and Claude are brilliant cloud tools that run on enormous data-center models. Hearth is a different thing on purpose — the AI runs on your computer, so it's free, completely private, and works without internet. It won't build you a whole app, but for everyday questions, writing help, and explanations it's wonderful — and nothing you type ever leaves your machine.

| Hearth | ChatGPT / Gemini / Claude | |
|---|---|---|
| Where it runs | Your own computer | A data center you don't control |
| Privacy | Nothing leaves your device | Your text is sent to their servers |
| Price | Free, forever | Free tier (limited) or ~$20/mo |
| Account required | No | Yes |
| Works offline | Yes, after one download | No — needs internet |
| Usage limits | Unlimited | Message/usage caps |
| Best for | Everyday questions, writing, explaining, brainstorming | Huge, complex projects & the very latest knowledge |
| Setup | Open a link, one ~1 GB download | Sign up with email |
When ChatGPT, Gemini or Claude are the right call
Be honest with yourself about the job. If you're building an entire website, working through a giant codebase, or you need the model to know about something that happened this morning, the big cloud tools win — they're larger, constantly updated, and connected to the internet. There's no shame in using the right tool.
When Hearth is the better choice
- You care about privacy. Hearth runs on your device, so your conversations physically can't be read by a server in the middle — it isn't a promise, it's how it's built.
- You want it free, with no account. No subscription, no sign-up, no “free trial” that ends.
- You're offline. On a plane, in a cabin, with the wifi off — Hearth keeps working.
- You're doing everyday things. Recipes, rewrites, explanations, a quick draft, a question you'd rather not type into a logged-in account.
What about Ollama, LM Studio, or other local tools?
Those are great if you're technical — they're power tools for people who already know what a “model” is. Hearth is the opposite: it's built for everyone. There's nothing to configure, no model names or jargon — you open it and you're talking. (Under the hood, Hearth's desktop app runs models natively on your computer's graphics chip for bigger, smarter answers.)
