Zero servers: where your text really goes with Weightless AI
Weightless AI has no server. Your text goes straight to the AI engine you choose, or never leaves your computer at all. Here is our commitment, and what it means in practice.
Most AI assistants work the same way: your text first goes to the extension maker, onto their servers, before it reaches the AI model. That lets them charge a subscription and measure usage… and it puts one more middleman between you and the AI.
Weightless AI made the opposite choice from day one: there is no Weightless server. Not a discreet one, not a “technical relay”: nothing.
Where your text goes
With a local AIGemini Nano, Ollama: nothing leaves
In practice, when you ask for a correction, a summary or a translation:
- with an online engine (Gemini, ChatGPT, Claude, Mistral…), your text goes directly from your computer to that provider, only to produce the answer;
- with a local AI (Gemini Nano, built into Chrome, or Ollama on your machine), your text never leaves your computer. Nothing goes over the internet.
Nobody else slips in between. Not us either, since we have nowhere to receive your text.
Our commitment, in four points
- No middleman server. Your text goes to the AI engine you chose, and nowhere else.
- No account to create. We don’t know your name, your email address or what you write.
- No trackers. Not in the extension, not on this site: no cookies, no audience measurement.
- The choice is yours. Online engine or local AI, you decide, tab by tab.
The one thing to know
An online engine does receive the text you send it: that’s its job. With the free Gemini key, Google may use your requests to improve its products. For confidential text (a contract, a medical file, a sensitive email), choose the local AI: that is exactly what it’s for.
Why this choice?
Because a server you don’t have can’t leak, can’t be hacked and can’t be sold. And because an assistant that reads your emails should be as discreet as possible.
