One per person

Maya's workspace, in the shape it is really stored: 18 facts across 12 topics, drawn out of 9 files she dropped in — and every one of them traceable back to the file that taught it.

The interactive version of this graph needs JavaScript. The facts and their sources are listed further down the page either way.

What people actually use it for.

Every line below works right now. Most of it happens in a WhatsApp thread; the rest you read back on the web.

Give it the pile

  • Profile dropHand over the PDF about me and let it pull out what matters.
  • Letter by photoPhotograph a letter on WhatsApp and never file the paper.
  • Spreadsheet recallDrop a sheet in and then ask it questions in words.
  • Thread keeperSave the mail I'll need again as a file, not a search.

Ask it, on WhatsApp

  • What do you knowAsk what it actually knows about me, and read the whole list.
  • Pattern recallAsk how often I fly to Mumbai, not what my next flight is.
  • Who is this againAsk who Kavya is and get back exactly what I told it.
  • Detail on demandGet the number I always end up hunting for in a folder.

Read my accounts, change nothing

  • Week at a glanceAsk what my week looks like without granting write access.
  • Old thread lookupFind what I agreed to in a mail thread from March.
  • Find it by contentFind the file by what is inside it, not what it is called.
  • Still open?Ask what's unfinished in Linear without opening Linear.

Things it holds for me

  • Reminder at a timeAsk for a nudge at six and get it on WhatsApp at six.
  • Standing task listKeep a task alive past the end of the conversation.
  • Twice-a-day check-inHear what's still open, morning and evening, unprompted.

Check its work

  • Show your sourceClick any fact and see the file that taught it.
  • Wrong-fact auditFind what taught it something wrong, and cut it out.

What you give it

Drop things in. It reads them.

A PDF, a spreadsheet, a page of notes, a screenshot of a letter. Drop it in your workspace or send it on WhatsApp, and Quillo reads it. What it keeps is the durable part — where you live, what you work on, who matters, what you avoid eating. A flight number is not durable. That you fly to Mumbai most months is. Every file it read is listed, with how many facts it added.

What it reads

  • Documentspdf  docx  txt  md
  • Spreadsheetsxlsx  xls  csv
  • Structuredjson  html  eml
  • Imagespng  jpg  webp

Images are read by sight rather than parsed. Other formats — slides, odt, vcf, ics, mbox, a zip — are accepted too, and how much it can pull out of one varies by format. It tells you what it got.

The Quillo journal in a browser. Today's entry, headed Tuesday 8 September, lists five things it learned — leads product at a Series B fintech in Bengaluru, based in Bengaluru from Jaipur, runs most mornings before 7am, flies to Mumbai roughly monthly, vegetarian and avoids dairy when travelling — each tagged with a topic. Below it, four files it was given, with the number of facts each added. A right-hand rail holds what it knows, three tasks, and a drop space for files.
One entry a day What it learned, what you gave it, and the topic each fact belongs to. No transcript — the talking happens on WhatsApp; this is the record of it.

The memory

Nothing it knows is hidden from you.

Most agents remember you somewhere you cannot look. Quillo puts it all on one page — the graph at the top of this one is the real thing. Click a dot and you get the facts behind it and, next to each, the file or message it came from. So when something is wrong, you can see that it is wrong, and see what taught it.

Five facts, and where each one came from

  • Leads product at a Series B fintech in Bengaluru work Profile.pdf
  • Flies to Mumbai roughly monthly for customer visits travel calendar-2026.ics
  • Runs most mornings before 7am routine You told me · 6 Sep 2026
  • Vegetarian; avoids dairy when travelling food You told me · 2 Sep 2026

Nothing it knows is unattributed. If you delete the source, you can see exactly which facts stood on it.

Connected apps

Read-only. Not a setting — a rule in the code.

Quillo can look at what is already in your account. It cannot change one thing in it.

Connect a calendar, a mailbox, a drive, your spreadsheets, your notes, your team's chat, your repositories. It reads them to answer you. It cannot send a mail, move an event, edit a file or leave a comment.1

The limit is not written in a prompt, so no prompt can undo it. Every tool call is checked against a whitelist of reading verbs, and refused if it also contains a writing one.2 An action nobody has classified is refused too: unknown means no.3 That matters here more than almost anywhere, because the documents flowing through these tools are exactly the kind that try to give instructions.

What it can do

  • Read your events, mail, files, notes and issues
  • Use them to answer you, and to remember what matters
  • Stop the moment you disconnect4

What it cannot do

  • Send, reply to or forward anything
  • Create, edit, move or delete anything
  • Reach an account you have not connected yourself

Eight accounts, each a single sign-in

  • Google Calendar Calendar
  • Gmail Mail
  • Google Drive Files
  • Google Sheets Files
  • Notion Notes
  • Slack Chat
  • GitHub Code
  • Linear Work
The Apps page in Quillo. A bordered panel headed “Read-only. Always, and by construction.” explains that Quillo can look at what is already in your account but cannot change a single thing in it — not send a mail, not move an event, not edit a file, not leave a comment — and that the limit is written into the code that runs every request. Two columns beneath list what it can and cannot do.
Apps The same promise inside the product, on the page where you connect an account.

Notes

  1. Enforced by composio.is_read_only(), which every tool call passes through before it runs. A model cannot talk its way past it, and neither can a document it is reading.
  2. The rule has two halves and both matter. The action must contain a reading verb — get, list, fetch, search, read, retrieve — and no writing verb at all.
  3. Which is why GMAIL_SEARCH_AND_SEND is refused: it reads, then sends. A deny-list alone would have let it through.
  4. Disconnect an account from the Apps page and the reading stops there. Connecting two accounts of the same app — a work calendar and a personal one — is normal, not an edge case.

Not built yet

Four things it does not do.

Everything above this line works today. These four do not exist yet — not in beta, not behind a flag, not waiting on an invite. They are what comes next, and this page will say so when they land.

  • Not built yet Daily digest The blogs and saved reading worth your time today.
  • Not built yet Mail summaries What arrived overnight that actually needs you.
  • Not built yet Calendar enrichment Who you are meeting, and what you last said to them.
  • Not built yet Schedules in the dashboard Managing schedules and richer task workflows on the web. Adding a task in the dashboard works today, and so does asking on WhatsApp for a nudge at a set time. Setting a timed reminder from the dashboard itself does not.

Everything it knows about you, you can read.
