Free AI Tools Online

AI tools that run on your computer. Write essays, generate stories, plan trips, chat with characters. Nothing uploads. Works on bad wifi or no wifi after the first visit.

AI tools that run entirely on your device — no API keys, no cloud accounts, no data leaving your browser. Every essay writer, story generator, trip planner, and roleplay character runs against a small language model downloaded once and cached for offline use. That means your prompts and outputs stay private by design, not by policy. After the initial model download, the tools work on a plane or a slow hotel connection. Browse the full collection below.

Frequently asked questions

Does the AI send my text to a server?
No. The language model runs inside a Web Worker in your browser tab, using your device’s GPU when available and falling back to CPU. Your prompts never leave your device — there is no server-side inference.
Why does the first use take a while?
The browser downloads the model weights once (roughly 400 MB–1.5 GB depending on the tool) and caches them in IndexedDB. Subsequent uses load in seconds, even offline.
Which devices support the AI tools?
Any modern Chromium-based browser on a machine with at least 4 GB of available RAM. Firefox and Safari have partial support. A discrete GPU speeds things up but is not required.
