Bills, renewals, the MOT, the dentist, the parcel, the thing you keep meaning to cancel — Sigil holds it all, warns you before anything's due, and just sorts it on WhatsApp. Connect your accounts once, and put the mental load down. Every action stays yours to approve, see and undo.
A real conversation. Every answer comes from an account you connected — and you can see and undo it all.
Plug your email, calendar, bank and energy into Sigil once. Then reach it however suits you — a message on WhatsApp, the web, or the AI tools you already use. One memory. One audit trail. One revoke button.
The renewal you meant to check. The bill you think you're overpaying. The appointment you keep not booking. It's an always-on tab open in the back of your mind — and it never quite closes.
So most of us just… put it off. 71% of us do.¹ And putting it off has a price: 1 in 3 say it's hurting their wellbeing,² and 26% are quietly overpaying because they left it too late.¹ It's not that you're disorganised. It's that it all lives in your head, scattered across thirty logins, with nothing joining it up.
57% wish it all lived in one place.³ So we built that place — one that doesn't just remember it, but acts on it.
Sigil holds your accounts and your context in one place that you own — not your AI vendor. Every AI you use borrows from it, on the terms you set, and you can watch and undo all of it.
Your accounts live in a neutral layer you control — not locked inside ChatGPT, or any one assistant. Switch tools whenever you like; your world stays put, and stays yours.
Checking a balance just works. Moving money, sending on your behalf, anything that matters — Sigil asks you first, every time. No creeping autonomy you didn't ask for.
Every action any AI takes through Sigil is written to a log the moment it happens. See exactly what was done, by which tool — and revoke any access in a single tap.
Anything you've connected to Sigil, you can use from WhatsApp — no app to open, no dashboard to learn. Connect more from your dashboard whenever you like.
Connect your email and bank, and Sigil quietly builds your memory — your bills and subscriptions, your next trip and the hotel you booked, your loyalty numbers, an upcoming viewing, a dentist appointment, when your MOT's due. Not by making you type any of it in. By reading the confirmations already sitting in your inbox. So your assistant answers "what are my regular bills?" or "what's my next trip?" without you ever telling it.
These are your private memory buckets — you decide exactly which AI sees which. The preferences, the people, the facts every assistant currently makes you repeat stop living inside one company's product and start belonging to you, ready for whichever assistant you reach for next.
Sigil reads booking confirmations and receipts to learn the facts — never to train a model, never shared, and everything it learns you can see and wipe in a tap.
Because Sigil already knows what's coming, it messages you before you'd have remembered — no reminders to set up, no dashboard to check. The quiet stuff that costs you when it slips.
Set it up once. After that, it's just a chat.
Create your Sigil — continue with Google or Microsoft, or an email — then link your bank, energy, email, calendar, car and the rest. Each one is a clean, official connection; your passwords and keys never touch your phone or any AI.
Say hello from your phone and start asking. Prefer to work in Claude, Cursor or the web? Wire those to your sigil too — same accounts, same rules.
Reading your own data just works. Anything sensitive pauses for a tap to approve — so you're never surprised by something done in your name.
A live record of every action, across every AI you've connected. Something looks off? Revoke that access in one tap and it stops immediately.
The big assistants want your accounts connected inside their product — owned by them, useful only there. Sigil is the opposite: a neutral layer that you own, that every AI borrows from.
Connect your bank once and it works in WhatsApp, on the web, and in Claude or Cursor — with one place to see and undo everything. Change your favourite AI next year; your world doesn't move.
You can — and you'll keep flipping between a dozen of them, each knowing only its own corner. Sigil is the one surface across all of them, in the chat app you already have open.
One question — “am I on track this month?” — can touch your bank, your energy and your calendar at once. No single app can answer that. Sigil can.
Banking is read-only and connected through regulated Open Banking — Sigil can see balances and transactions, and can never move money. Your credentials are encrypted with keys even we can't casually read.
Anything sensitive asks you first, every action is logged, and you can cut off any connection in a single tap. Control, not blind trust.

Sigil is a personal credential-management and permission layer. It lets an individual securely connect their own accounts — such as Gmail, Google Calendar, Google Drive, their bank (via regulated Open Banking) and their energy supplier — and then use those accounts through the surfaces they choose: a WhatsApp assistant, the web, or AI tools such as Claude Desktop, Cursor and ChatGPT — without giving any of those tools direct access to the underlying credentials.
When a user connects an account to Sigil, Sigil acts as a permission layer between that account and the user's assistants. The user grants narrow, revocable permissions — for example, allowing an assistant to send a single email on their behalf, rather than read access to their entire inbox.
Every action taken through Sigil is recorded in an audit log accessible to the user in real time. Sigil does not access, store, or process a user's data on its own behalf — every API call is initiated by a user-authorised assistant at the user's direction.
Sigil's data handling, retention, and deletion practices are described in detail in our Privacy Policy. Sigil's security model — including how user OAuth tokens are encrypted, who can decrypt them, and what to do if you find a flaw — is documented in our Security Policy. Sigil's Terms of Service are also available.
Connect your bank, energy, email and calendar. Message Sigil on WhatsApp. Approve what matters, see everything, revoke anytime.
