Catalogue makes organizing fun.

A gamified personal organization tool inside your WhatsApp and Telegram. Save links, notes, and to-dos. Catalogue keeps them in one place, tracks your follow-through, and shows you how you're doing each week.

No app. No account. Just text it.

01 / how it works

Save it. Organize it. Actually follow through.

No new app. No second inbox. Catalogue works inside the messenger you already have open all day — WhatsApp or Telegram. Send it anything you want to keep, and it saves it, helps you create and share lists for it, and keeps score of what you actually come back to.

i.

Send anything

Links, articles, voice notes, contacts, screenshots, to-do items, half-formed thoughts at 2am. One place for everything you'd otherwise lose in a dozen chat threads.

ii.

Organize it

Catalogue helps you create lists to organize your items and easily share them. Find them later by idea, list, or keyword.

iii.

Tracks your follow-through

Saving is easy; following through is the hard part. Catalogue keeps score — what you revisited, what you completed, what's still sitting untouched. Each week you can see whether you're actually making progress or just collecting good intentions.

The boring parts
that actually matter.

Capture anything

Links, voice notes, screenshots, contacts, half-thoughts at 2am. It reads the text inside your images and transcribes your voice notes — so all of it is searchable later.

Just describe it

Ask for "that piece about sleep and parenting" and get the right thing back — even if the title said none of those words. No folders to remember.

Reminders in a tap

Text "remind me to read this" and it offers times right there — This evening, Tomorrow 9am, in an hour. Tap one. No date-picker, no form.

Lists you can share

Organize things into lists, then share one with a friend or partner in a tap. You both add to it — each from your own chat.

Streaks & follow-through

Every week: what you actually revisited, what you finished, and what's still sitting there. Saving is easy — this is the part that gets you to follow through.

Private by design

Encrypted at rest, isolated per person, never used to train models. Your archive is yours — delete everything any time, or ask us for a full export.

Feed the cat. Fairly.

Things people ask before adopting.

Is my data private?
Yes. Your archive is encrypted at rest. We don't train models on your content. We don't sell anything to advertisers — our only revenue is your subscription. You can delete everything at any time, and request a full export whenever you need one.
Do I need to install anything?
No. You add Catalogue as a contact in WhatsApp or Telegram. That's the whole setup. There's also a web app at ctlg.to for people who want a visual view of their archive, but the chat is the product.
What can I actually send it?
Text, links (articles, YouTube, tweets, docs), voice notes (transcribed automatically), images (text is extracted), and contacts.
What if I use both WhatsApp and Telegram?
On House Cat and above, both are included and share one archive. Send from either — Catalogue remembers. One archive, two windows.
Is there an iOS / Android app?
No — that's intentional. You already have a messaging app. The point of Catalogue is to not add one more icon to your home screen. When you want a visual view of your archive, it's on the web at ctlg.to — nothing to download.
Is Catalogue a chatbot?
No. Catalogue saves and retrieves things you explicitly send it. Type a general question and it'll tell you it can't help — try ChatGPT or a search engine for those.
Does it answer questions or write things for me?
No. No drafting, no answering, no advice. Catalogue files what you send and finds it again later. That's it.
Is it a search engine?
It only searches the things you've sent it — your captures, your lists, your reminders. It doesn't crawl the web.
Is it always-on or proactive?
No. Catalogue acts only when you explicitly send it something. It doesn't watch your messages, listen in the background, or initiate conversations.

Your notes deserve better.
