The problem

Your work lives in twelve tabs. Your family runs on WhatsApp. Your household exists somewhere in your inbox. You're one person. Your tools aren't.

The system

Three layers.
Every area
of your life.

01Swimlanes
Life domains

The major contexts of your life. Everything belongs somewhere. No task floats in a void.

02Threads
Big things in motion

Each with a clear definition of done. Whether it takes a week or a year — it lives in one place.

03Tasks
One thing at a time

Each with a deadline, effort estimate, and a daily-recalculated priority score. Done by you — or delegated.

Priority engine

The right task
at the right time.
Always.

Every task is scored daily across six factors. No morning triage. No forgetting what matters. Just a ranked, capacity-aware shortlist — ready the moment you open the app.

01
Time pressure
Deadline versus effort remaining — not just when it's due, but whether you have enough time left to finish it.
02
Consequence of missing
Some missed deadlines are inconvenient. Others are catastrophic. Mainthread knows the difference.
03
Stakeholder impact
Failing your spouse or your team hits differently than failing only yourself.
04
Thread importance
A task inside a high-priority project rises above one in a lower-priority area — even with similar deadlines.
05
Your judgment
Flag something as important and the system listens. Your instinct, factored in alongside everything else.
06
Dependency order
Blockers rise automatically. You can't do the DMV without renewing insurance first.
AI agents

Some tasks
don't need you.

Mainthread agents browse the web, fill forms, research vendors, book appointments, and complete real-world administrative work on your behalf. You stay focused on what adds real value.

Browser automation
Agents navigate real websites, fill real forms, and complete real workflows — no copy-paste required.
Playbooks & Skills
Teach agents how you do things. Your preferences and workflows — remembered permanently.
Human-in-the-loop
Agents pause and ask before taking sensitive actions. You approve; they execute. Full control, zero tedium.

FAQ

Questions we get asked.

What counts as an agent task execution?

Each time an agent completes or attempts a delegated task on your behalf. Viewing, approving, or replying doesn't count toward your limit.

Can I change plans?

Yes, any time. Upgrades are immediate; downgrades apply at the next billing cycle. No penalties, no friction.

What happens if I hit the 50-execution limit on Delegate?

You'll be notified and can either upgrade to Autopilot or wait for your next monthly reset. Agents won't act without your knowledge.

Is my data private?

Yes. Each account is fully isolated. Agents operate on your behalf only, with your explicit approval for every sensitive action.

Do you offer refunds?

If you're not satisfied within your first 14 days, we'll refund you — no questions asked.

Does Mainthread work for non-technical people?

Absolutely. Mainthread is built for anyone juggling multiple life commitments — lawyers, parents, managers, freelancers. No technical background required.
