Democratized AI for all.
Good AI should be free for everyone, and it should stay yours.
FreeSpark is a free AI assistant that runs on the computer or phone you already own. There is no account, nothing to pay, and no limit on how much you use it. It works out what your device can handle, picks the best AI model that fits, and gives that model the ability to plan, look things up, use tools and check its own work. We call that Model + Spark.
Free for everyone
Nobody pays per message, so nobody is priced out. The AI models are open and the app is just a web page.
Private by design
The AI runs inside your browser, on your own device. What you type, your notes, your files and your photos never leave it. Looking things up on the web is optional and can be switched off.
No datacenters, no water
No giant server farm does the thinking for you. The only chip working is the one in your device, using about as much power as a laptop, with nothing to cool.
How it works
- Check your device and pick a fast, capable AI model it can run. The model downloads once and stays on your device.
- Gather the basics before asking the AI anything: the date and time, your notes, any files or links you shared.
- Send each job to the right place: math to a calculator, code to a workspace, facts to a web search, files to your folder.
- Plan bigger requests as a short checklist and work through it one item at a time.
- Check the work: code gets run, numbers get checked, and if part of your request was missed, the AI is asked to fill it in.
What runs where
| On your device | Optional, over the internet |
|---|
| The AI itself, pictures it makes, your chats, notes, files, voice, and everything it checks | Downloading a model the first time · looking things up on the web (through FreeSpark's own search) · weather and currency rates |
What the server keeps
Nothing about you. The FreeSpark server has no database, no accounts and no cookies, and it writes no user data to disk. Your chats, notes, files and settings live in this browser only, and clearing site data erases them for good.
When looking things up on the web is on, one thing does leave your device: the search itself, built from your message, plus the address of any web page you ask FreeSpark to read. Those go to the FreeSpark server, which runs the search and sends the results back. Searches are not written to any log. The server keeps only a short-lived count of requests per visitor, in memory, so one person cannot hog the search service.
Like every website, the server keeps ordinary logs of when the page and its files were requested. Turn off Look things up on the web in Settings, and the only thing that ever leaves your device is the one-time model download.
Support the creator
FreeSpark is free, has no accounts and shows no ads, and it stays that way. It is built and paid for by one person. If it is useful to you, buy the creator a coffee; that link is the only thing here that ever asks you for money, and using it is entirely optional.
AI can make mistakes. FreeSpark checks its work, but please double-check anything important. freespark.app · A PyroSoft Productions, Inc. project.
