Crumbs understands the message, transcribes voice notes, and keeps the item available for a later question or reminder.

Retrieve what you actually saved
Ask naturally: “What was that restaurant Priya mentioned?” Recall is grounded in your saved crumbs, not a made-up memory.
Before you message Crumbs
Where it runs
Crumbs runs on servers, not on your phone, so it can receive a message and return it later. Your saved crumbs are stored encrypted.
How it understands
Your content is sent to Google’s Gemini API to understand messages, transcribe voice notes, and find what you ask for.
Your choices
Crumbs does not sell your content or use it for ads. Your data is exportable and deletable at any time. Read the privacy policy and terms.
Free tier and limits
The free tier includes up to 50 crumbs each month. Paid plans are available if you outgrow that limit.
Give everyday details a place to land
Capture Anything, Zero Friction
Send a note, idea, or to-do the moment it strikes. No forms, no tags, no app to open, just type or speak in WhatsApp and it's saved.
Reminders That Actually Fire
"Remind me to pay rent on the 1st at 9am" or "every Monday at 9". Crumbs understands natural time and nudges you exactly when you asked.
Ask for It Back in Plain Words
"What was that restaurant Priya mentioned?" Crumbs answers only from what you actually saved. It never makes a memory up.
Voice Notes, Split Neatly
Ramble while commuting or cooking. Crumbs transcribes your voice note and separates it into clean, individual items.
Links, Photos, Tickets & Pins
Paste a URL, forward a flight ticket, share a location pin or a business card. Crumbs files it and offers a reminder when it makes sense.
Multilingual & India-First
English, Hindi, Hinglish and more. Dump and recall in whatever language feels natural, Crumbs keeps up.
Clear About Data
Crumbs runs on servers and sends content to Google Gemini to understand it. Saved crumbs are encrypted, never sold, exportable and deletable. See the details above before you message.
Quiet & Reversible
Calm acknowledgements, no spammy chatter, easy undo. Crumbs is built for your peace of mind, not for engagement metrics.
Your first crumb can be one message
Crumbs works in WhatsApp. The free tier includes 50 crumbs a month; paid plans are there only if you outgrow that limit.
Frequently Asked Questions
What is Crumbs?
Crumbs is a private second brain you talk to on WhatsApp. You dump anything you want to remember, notes, ideas, todos, reminders, links, photos, voice notes, contacts, locations, and ask for it back later in plain language. It's the calmer upgrade to messaging yourself.
Do I need to install an app?
No. Crumbs works entirely inside WhatsApp, no new app to learn. A dedicated Crumbs mobile app for Android and iOS is coming soon, where the same saved items are easier to browse and connect.
Is Crumbs private?
Private, with one important caveat you should know. Unlike our other apps, Crumbs runs on servers rather than on your phone, because it has to receive your message and hand it back later. Your crumbs are stored encrypted, and the content is sent to Google's Gemini API so Crumbs can understand it, transcribe voice notes and find what you ask for. We do not sell it or use it for ads, your data is exportable and deletable at any time, and Crumbs never fabricates a memory, recall is grounded only in what you actually saved. The full detail is in the privacy policy.
What languages does Crumbs understand?
Crumbs is multilingual and India-first. It understands English, Hindi, Hinglish and many other languages, so you can dump and recall in whatever way feels natural.
Who builds Crumbs?
Crumbs is built by PurposeLab Studio, the maker of simple, privacy-first apps like Zolio (formerly Folio), WaterWise, BP Log and Hushly.
