AI drafting that reads the thread
An AI email composing assistant that has read the thread.
Drafts use the full conversation, your past replies to that person, and the way you actually phrase things. The assistant stays quiet until you ask. No "rewrite this in a friendly tone" toolbar tricks.
Re: marketing launch — ready to ship
Hey Elena — we're good on our end. Final copy is in the doc, design's signed off, legal cleared the disclaimer. The only thing holding us up is your final approval on the press list. Can you take a look today, or should we push?
Priya — yes, ship it whenever you're ready. I trust your judgment on the timing. One ask: send me the final press list before it goes out, so I can flag anyone who should hear about it first. Don't wait on me beyond that.
↑ The assistant noticed Priya prefers short, action-led replies (12 past threads).
How it stays in your voice
Trained on what you've already written.
Most AI assistants impose a tone. They have a default — that LinkedIn-corporate-friendly default — and you have to fight it to sound like yourself. Fizzle goes the other way. It studies your sent folder, learns how you talk to different people in different threads, and drafts that way. If you usually open replies with "Yeah —", it will too.
- Per-recipient style memory — clients vs. teammates vs. investors.
- Picks up your sentence length, punctuation habits, and signoffs.
- Drafts arrive when invoked, not the moment a message lands.
What it actually does
Three jobs. Done quietly.
No "AI everywhere" dashboard. Three commands, all keyboard-driven.
- ⌘D Draft a reply to this thread.
- ⌘K Summarize what this thread is actually asking.
- ⌘. Suggest a follow-up to a stalled conversation.
On the private mode
On-device drafting for the threads that shouldn't leave your laptop.
For sensitive mail — legal, HR, fundraising, anything tagged private — drafting runs entirely on your machine. The model is smaller, but it works. Cloud drafting is used for everything else, with content never retained after the request.
