Launching December 2026 · free to start

Know what needs you before you open your email, chats, calendar, tasks, files or docs.

STACK reads your email, chats, calendar and tasks, then hands you one brief: what matters, why, and the next step, already drafted and waiting for your OK.

8:47 AM

You haven't started yet.
You're already behind.

Twenty-three emails. Fourteen Slack threads. A meeting that moved. A board that changed overnight.

Somewhere in that pile is the one thing that actually matters today, and finding it is your job before you've done any work at all.

Now, the same morning with STACK.

How it works

From the pile to a plan, in four steps.

The same morning, with STACK. Scroll through the day.

8:48 AMUnderstand

STACK reads it all, so you don't have to.

It connects to the apps you already use, read-only, and turns the overnight pile into a few sentences, each linked back to the email, thread or file it came from.

STACK · Since yesterdayExample

  • Launch: the design review moved to 10:00 today, so two of your tasks are now due before it.

    CalendarLinear

  • Sarah at Acme has asked twice about the Q4 proposal. She needs it by tomorrow.

    GmailSlack

  • Overnight, three pull requests merged and the build on main started failing.

8:49 AMPrioritize

Three things matter today. Each one says why.

Not a longer to-do list. A short one, ranked, and every item carries its reason: who's waiting, what's due, what it blocks. Everything else stops shouting.

STACK · PrioritiesExample
  1. 1Send Sarah the Q4 proposalAsked twice · due tomorrow
  2. 2Fix the failing build on mainBlocks today's release
  3. 3Prep for the 2:00 launch syncYou're presenting · 2 open questions
Can wait: 19 newsletters, 6 FYI threads, 11 notifications
9:02 AMAct

Handle it here. Nothing happens without your OK.

Ask STACK to draft the reply, create the task or book the meeting. It prepares everything, then waits for you to approve, edit or cancel. It never acts on its own.

STACK · AskExample

Reply to Sarah and tell her the final proposal will be with her by noon.

Email draft · from your Gmail

To sarah@acme.example · Re: Q4 proposal

Hi Sarah, thanks for your patience, and sorry for the wait. You'll have the final Q4 proposal from me by noon today.

Waiting for your approvalCancelEdit Approve
5:42 PMMove forward

End the day with nothing slipping.

STACK keeps watch on what's next, who you're waiting on and what's quietly drifting, so tomorrow starts where today left off.

Letting an app read your work is a big ask. Here is exactly what STACK does with it. Each of these is how the product works today.

to start, from December 2026

Read-only by default

STACK asks for read-only access wherever an app lets you choose. Changing anything needs your separate OK.

You approve every action

Drafts, tasks and invites wait for you. Nothing is sent, created or changed on its own.

Encrypted connections

Every token for your apps is encrypted at rest with AES-256-GCM and never sent back to your browser.

Shows its sources

Every answer lists exactly which apps and items it used, with links back to the original.

Disconnect means gone

Disconnect an app and STACK revokes access where the app allows it and deletes what it imported.

Leave whenever you want

Delete your account from Settings at any time. Your workspace and everything in it is removed.

Questions, answered.

When can I use STACK?

STACK opens in December 2026. Sign-in is switched off until then.

Will it be free?

Yes, it's free to start. There's no card and no trial clock. If paid plans come later, you'll hear about it before anything is ever charged.

What can STACK see in my apps?

Only the apps you connect, and read-only wherever an app lets you choose. Every connection's token is encrypted with AES-256-GCM and never sent back to your browser.

Will STACK send emails or change things on its own?

No. When STACK drafts a reply, a task or an invite, it waits for you to approve, edit or cancel it. Nothing is sent, created or changed on its own.

Which apps does it work with?

Email, calendar and files from Google, plus chat, task, CRM, support, code and research tools - many of them scroll past at the top of this page, and you'll see every one when STACK opens. Each connects in about a minute.

Can I take my data back out?

Disconnect an app and STACK revokes its access where the app allows it and deletes what it imported. You can delete your whole account from Settings at any time.

Does it work on my phone?

Yes. STACK runs in your browser on any screen - check your brief on your phone, act on it at your desk. Nothing to install.

Tomorrow, 8:47 AM

This time, you start ahead.

STACK opens in December 2026. Connecting your first app will take about a minute, and it's free to start.
