Rudeus, for WhatsApp

Just send it to Rudeus.

A question, a voice note, a forty-page PDF, a messy spreadsheet. Rudeus reads it, works it out and replies in the same chat, in plain words, with its sources when it looked something up.

  • Nothing to install
  • Works in the WhatsApp you have
  • Replies with files, not just text

What people send it

Most people start with one kind of message and find the rest by accident. Here is the whole list, with the sort of thing people actually write.

  1. Questionsi

    Ask anything. When the answer depends on what is happening now, Rudeus searches the web and tells you where it looked.

    What does the new tax regime mean on a ₹9 lakh salary?

  2. Documentsii

    Forward a PDF, a Word file or a photo of a page. It reads the whole thing and answers from it.

    Which clause lets us end the lease early?

  3. Voice notesiii

    Speak instead of typing. Rudeus listens and replies in text, or in a voice note if you would rather listen.

    Hold to record, let go, done.

  4. Numbersiv

    Send a spreadsheet. It does the sums for real, in code, and draws the chart you asked for.

    Which district improved most since June?

  5. Handouts and slidesv

    Ask for a one-page PDF or an editable slide deck, and the file arrives in the chat.

    Turn this into six slides for Monday.

  6. Remindersvi

    Tell it when. It messages you at that time, even days later.

    Remind me at 6 to call the school.

  7. Your libraryvii

    Keep files privately, or share them with everyone on Rudeus. Ask across all of them later, or quiz yourself.

    Quiz me on the safety manual.

  8. Calendarviii

    Optional. See what is coming up or plan a meeting. Nothing changes until you say yes.

    Am I free on Thursday afternoon?

Getting in

Three steps, once

Rudeus is by invitation for now, so the people using it can trust who else is there.

  1. 1

    Get an invite

    Someone who runs Rudeus sends you a link. Tap it on your phone and send the message it fills in.

  2. 2

    Sign in with Google

    Google sign-in links your account. Rudeus asks only for your email, so your chats and files stay yours.

  3. 3

    Just chat

    Type, speak, forward or attach. That is the whole manual.

Your Google account

The small print, in large print.

Google Calendar access is optional and requested separately, only when a Calendar task needs it. Here is what that means in practice.

  • Only when you ask.Calendar permission appears the first time you ask for Calendar work. Everything else works without it.
  • Nothing changes without your yes.Rudeus shows the event first and creates, changes or deletes it only after you confirm in WhatsApp.
  • Leave in one message.Send /logout to remove the Google connection and ask Google to revoke its access. /clean-slate deletes everything Rudeus holds about you, except whether your number is allowed.
  • Not for sale, ads or training.Google Calendar data is not sold, used for advertising or used to train a general-purpose AI model.
