Quillfox reads your inbox, calendar, and notes — then quietly drafts the reply, finds the 25-minute gap, and reminds you about the thing you said you'd do. Warm, plain-spoken, and never pretending to be a person.
Light morning, busier after lunch. Two things to watch:
Connect what you already use, tell Quillfox how you like to work, and let it handle the small decisions so you keep the big ones.
Gmail, Calendar, Notion, and Apple Notes in two clicks. Quillfox reads them on your machine and builds a private picture of what's actually going on — no servers in the loop.
One short chat sets your tone, your no-meeting hours, and the people you always reply to first. Quillfox remembers it forever — and you can edit any memory in plain English.
Drafts wait for your nod. Reschedules ask first. Nudges arrive at 5:40, not 5:59. Quillfox does the choreography and hands you a day that already mostly works.
Quillfox reads every thread, sorts the 6 that need you from the 84 that don't, and writes first-draft replies in your voice. You skim, tap send, move on — the way email was supposed to feel.
"Coffee with Diego, sometime next week." Quillfox checks both calendars, dodges your focus blocks, and sends three options that actually work.
Birthdays, that book you promised to send, the follow-up you swore you'd do. Quillfox keeps the threads you drop.
From two-line replies to a hard "no thanks," Quillfox matches how you actually sound — then waits for your edit.
Who you're meeting, what you last said, what's still open. Pulled from past threads and quietly waiting in the invite.
An assistant this useful only works if you trust it completely. So Quillfox runs the model on your own machine. Your inbox, calendar, and memories never touch our servers — and there's nothing to leak because there's nothing stored with us.
Every plan runs on-device and keeps your memories private. Upgrade only when you want more devices and the deeper integrations.
For trying Quillfox on your main machine and seeing your mornings change.
For the person who wants Quillfox on their laptop, phone, and tablet — fully synced.
For families and small teams who share a calendar and a hundred loose ends.
"It drafted a reply to a client I'd been dreading for a week. I changed two words and hit send. Quillfox just knew the tone."
"I have ADHD and the 5:40 nudge before pickup has saved me more times than I can count. It feels like a friend, not an app."
"My calendar is medical and confidential. Quillfox running on-device is the only reason I'd let an assistant near it — nothing leaves the laptop."

The free Quiet plan genuinely costs nothing and runs forever on one device. You pay for the things that need infrastructure on our side — end-to-end encrypted sync across devices, the secure connectors to Gmail and Notion, and shipping you a new on-device model every few weeks. The intelligence is local; the plumbing isn't free.
For open-ended reasoning, it can't — and we don't pretend it does. But drafting a reply in your voice is a narrow, well-grounded task: Quillfox has your past 5,000 emails as style context and the live thread as content. We fine-tuned specifically for that, and in blind tests 81% of Companion users couldn't tell Quillfox's draft from one they'd write themselves.
No outbound action happens without a tap from you, ever — that's a hard rule, not a setting. Quillfox drafts, proposes, and queues; you approve. The only thing it does autonomously is read and organize, and you can pause even that for any inbox with one switch.
Any Apple Silicon Mac (M1 or newer) with 16 GB of RAM, or a Windows machine with 16 GB and a recent NPU. Quillfox idles at near-zero and only spins up the model on demand — typical usage adds about 4% to a workday's battery drain on an M2 Air.
Yes. Each person on a Household plan gets their own private Quillfox with its own memory store — your inbox and notes are never visible to anyone else. The only shared surface is calendar availability, so Quillfox can coordinate a dinner without ever exposing why you're busy.
Install Quillfox in ninety seconds. Connect your inbox and calendar. Tomorrow morning, just ask it what your day looks like.
