Draft
Reply in your words
Tell it what to say — “politely decline, propose next Tuesday” — and pick a tone. It answers in the language of the email, so a Spanish thread gets a Spanish draft. You always read the draft before it goes anywhere.
No server · No account · No telemetry
AI email replies that stay on your machine
emailito lives inside Gmail and Outlook. It drafts replies and summarizes long threads using a model that runs on your own GPU — so the email you are reading is never uploaded, logged, or remembered.
Free and open source. Works in Chrome and Edge.
Where does your email actually go?
your machine
The email on screengmail · outlook

Nothing crosses the line. The model runs inside the browser on your GPU. No request carries your email anywhere.
What it does
Three things, inside the mail you already use
Summarize
Catch up on a long thread
An overview, the key points, and who owes what — in the thread’s own language. The private alternative to the AI summaries built into your inbox.
Insert
Straight into the reply box
One click puts the draft in the compose box — opening the reply for you if none is open — or copies it if you would rather paste it yourself.
Engines
You pick the trade-off, not us
Two engines keep everything on your computer. The third is better at writing, and we tell you exactly what it costs you.
Browserwebgpu · default
A compact model runs inside Chrome on your GPU. First use downloads it once and caches it; after that, drafts start instantly and work with no network at all.
Needs a WebGPU-capable machine with ~3 GB free VRAM · ~2 GB download, once · smaller and larger models selectable in settings
Stays on your machine
Ollamalocalhost:11434
Already run Ollama? Point emailito at it for bigger, better local models. The extension refuses any Ollama URL that is not loopback, so this cannot quietly become a remote call.
Needs the free Ollama app on the same computer · any model you have pulled
Stays on your machine
Claudeyour own api key
The best drafts, using your own Anthropic API key. Your email goes straight from your browser to Anthropic — never through a server of ours, because there isn’t one. You see a full disclosure before the first request.
Needs an Anthropic API key with credit at console.anthropic.com · a separate balance from a Claude.ai subscription
Sent to Anthropic
Not sure which model to run? Choosing a model has the VRAM figures for all six on-device models, why summaries punish small models more than replies do, and how to find out what your GPU can take.
Privacy
Enforced by the browser, not promised by us
“It stays on your machine” is easy to write on a website. In emailito it is a line in the extension’s manifest that Chrome itself enforces — the complete list of hosts the extension is permitted to contact:
// manifest.json — content_security_policy connect-src 'self' https://api.anthropic.com // Claude mode only https://huggingface.co // model weights https://*.hf.co // (data, not code) http://localhost:* // your Ollama http://127.0.0.1:*
- ✓Anything not on that list is blocked by Chrome — even if our code, or a dependency, tried it.
- ✓No mail API, no OAuth scope. emailito reads the thread already rendered on your screen and nothing else in your mailbox.
- ✓Nothing is stored. No history, no per-contact profiles. A draft exists in the panel until you insert or discard it.
- ✓There is no emailito server. No account, no sign-up, no analytics — the developer has no way to see your email, or whether you use it at all.
- ✓Open source. Every claim here is checkable in the repository, including this page.
