One assistant for everything you juggle
sisir is your personal AI assistant for reminders, tasks, calendar, contacts, notes, and files — it captures everything, organizes quietly, and follows up so you don’t have to.
Jot it down. sisir files it as a note, task, or reminder.
Type, dictate, or snap a photo. Auto mode classifies and files it — into the right notebook, with the right due date, on the right person’s list. No forms, no folders, no friction.
- Auto-classify
- Voice capture
- Photo & attachments
Your day, held gently
Calendar that thinks ahead
Events from all your accounts in one week view, reminders interwoven as check-off items, and focus blocks sisir holds for you.
Tasks & reminders that follow up
Priorities, subtasks, and due dates — with sisir nudging at the right moment instead of you keeping it all in your head.
Notes & notebooks with context
Real documents, not scraps — linked to the calendar events, tasks, contacts, and files they belong with. sisir adds what you’ll need.
An inbox with an agent
Agent Q works your mail queue — files receipts, adds flights to trips, drafts checklists — and always asks before anything irreversible.
Contacts that do things
Every contact is one tap from an assignment, a shared list, or a call — with profiles that fill themselves in over time.
My Files, self-organizing
Chat files, uploads, and inbox attachments land in one searchable library, already attached to the trip, project, or person they belong to.
Write it down. Watch it happen.
Intentions you track get completed — the ones you keep in your head get carried. sisir makes tracking effortless, then quietly sorts the signal from the noise: Up next always shows the most relevant thing to do now, so you act on what’s important, not just what’s loudest.
One mom, two teenagers, zero nagging
Ella has SAT practice and a room to clean; Noah has trash night and a history essay. One line each to assign — sisir reminds them at the right moment, they check it off, and you see it done. The reminders come from sisir, not from you — so homework gets finished, chores get owned, and dinner stays peaceful.
- Kids own their lists — study and chores side by side, checking off feels good
- Progress at a glance — "2 of 3 done" without a single check-in text
- Kid-safe spaces, parent-managed — and it works just as well for trips and teams

The web, minus the typing
sisir stands by on every page. It fills forms from your encrypted data, captures anything useful — confirmations, receipts, listings — into your world, and answers questions grounded in both the page and your own files.
- Type once, fill everywhere — sensitive fields masked or kept local-only
- Capture page content straight into notes, tasks, and trips
- A "My data" ledger you can audit, edit, and delete — field by field
Your life’s data deserves a vault, not a feed
Everything is encrypted end-to-end — on your devices and on our systems. Per-field sync control means the most sensitive things never leave your browser. And there are no ads, ever: you are the customer, not the product.
- End-to-end encryption
- Per-field sync control
- Agent Q asks before acting
- No ads, ever
“I’ve spent thirty years keeping people’s most sensitive data safe — health records, employee files. That’s the standard your reminders, your kids’ chore lists, and your passport number deserve. We built sisir so the assistant that knows your whole life is also the one that guards it.”
