Email intelligence
that triages your inbox and drafts every reply.
The AI inbox that runs in your browser — never on our servers. MiniBrief triages what matters inside Gmail and Outlook, drafts replies in your own voice, and clears the noise. Your email stays yours.
The real product, live below — no install, nothing to sign up for
What used to eat your morning now takes minutes.
MiniBrief works inside your existing webmail the moment you open it. Your email content never leaves for our servers.
Most AI email tools store your inbox on their servers. MiniBrief stores none of it.
Trust here is structural, not a badge we bought. It comes from how the product is built. By default we send only a subject line and a preview of about 120 characters. Full message text is sent only for features you turn on yourself, and only for the message you opened.
MiniBrief vs. the usual approach.
Same inbox help. A fundamentally different deal with your data.
The work it does, every day.
Not a list of features — the work MiniBrief takes off your plate the moment you open your inbox.
We read every thread for you.
MiniBrief scans the full thread the moment you open it. However long the back-and-forth, you get the key points, who needs what, and the next action.
- TLDR, action items, and sentiment for any thread length
- Reads up to 4,000 characters per email for accuracy
- Cached per email — second open is instant, zero token cost
We draft replies in your voice.
MiniBrief studies your sent folder to learn your voice, including greetings, sign-offs, and formality, then generates replies that read like you wrote them.
- Learns from up to 100 of your real sent emails
- Reply by intent — approve, decline, follow up, schedule, and more
- Three tone modes (voice, brief, warm) plus a tone check that flags and fixes harsh lines
We keep your client relationships warm.
MiniBrief builds a profile for every client — status, cadence, history — and quietly watches the threads. When someone important goes quiet, you hear about it before the relationship cools.
- Client profiles: status, cadence, notes, and next check-in
- Triage and meeting prep that know who's a client
- Relationship-health alerts when a client goes quiet
We make unsubscribe permanent.
One click does two things. It fires the RFC 8058 unsubscribe and writes a permanent filter, so if the sender rotates subdomains the next email is still trashed automatically.
- RFC 8058 one-click + mailto fallback
- Persistent Gmail server-side filter (not a label rule)
- Survives newsletter subdomain rotation
Fires the sender's RFC 8058 unsubscribe AND writes a Gmail filter so future emails skip the inbox.
And it keeps earning its keep.
Beyond triage, drafting, and unsubscribe, MiniBrief quietly handles the rest of the inbox grind.
Catch-up reports
Back after time away? One ranked digest of what actually happened, instead of a wall of unread rows.
VIP alerts and escalation
Flag the people who matter. If a VIP thread goes quiet past the window you set, MiniBrief raises it to critical.
Smart classification
Every email is sorted by importance and type the moment it lands, so noise stays out of the way of what needs you.
Meeting prep
Before a call, MiniBrief pulls the thread history into a tight brief so you walk in already up to speed.
Snooze with reliable wake
Archive a thread now and return it to the inbox in minutes or hours. Wake timers survive browser restarts, so nothing is lost.
Tone check before send
Scores a draft for professionalism and flags aggressive, passive-aggressive, or unclear lines before you send it.
Commitments tracking
MiniBrief pulls promises and deadlines out of your threads — what you owe and what's owed to you — and flags them before they slip.
ROI you can see
Time saved, response times, top senders, and where your inbox hours actually go — the proof MiniBrief is earning its keep.
Delegation and team
Hand a thread or a full catch-up report to your EA or chief of staff. Role-based delegates keep the right people in the loop.
Four steps to a managed inbox.
MiniBrief reads and sorts your mail in your browser. Your account keeps settings and VIPs in sync, and your email content is never stored.
Install and sign in
Add the extension to Chrome or Firefox and create your MiniBrief account. Setup takes about a minute.
Open Gmail or Outlook
The panel appears next to your inbox, and triage begins as soon as your mail loads.
Read the brief
Catch-up reports, voice-matched drafts, and one-click unsubscribe, all without leaving your inbox. No AI key to bring.
Set your VIPs
Flag the people who matter. MiniBrief monitors those threads and escalates to critical if they stay silent past your window.
Your email never leaves your browser.
Most AI inbox tools upload your mail to their servers. Watch where yours actually goes.
You open your inbox.
Gmail or Outlook — right where you already work.
It all happens right here.
Your email is read inside your browser, on your device.
Our servers never see it.
Your email content is blocked from our servers — only your settings ever sync.
Private by construction.
Not a policy you have to trust — it's how MiniBrief is built.
A note from the founder.
I built MiniBrief because my inbox was beating me.
Hundreds of unread emails, no structure, no idea what actually needed a reply. Newsletters, promos, and junk piling up until the one email that mattered was buried three pages down, and some days I’d miss it completely. Threads twenty messages deep that I had to read top to bottom just to find the one question hiding inside. Every time I needed something, I was searching, scrolling, and hoping.
I didn’t want a prettier inbox. I wanted my day back.
So I built the thing I needed. MiniBrief reads your inbox, clears the newsletters and noise away from what actually matters, pulls the answer out of long chains, and drafts the reply in your own voice, right inside Gmail and Outlook.
What used to eat your morning now takes minutes. Nothing important slips through, and you get a whole lot more of your day back.
