AI · Capture and recall

BrainSync AI remember in your own words

BrainSync is live in production. It is a second brain for people who think in fragments, not files. Capture a thought as a note, attach a reminder, see what rings next on Today, and find it later by searching — not by remembering a folder path.

The problem

Notes, alarms, and search usually live in three apps. A thought dies in a camera roll or a locked note. Retrieval had to feel like asking a person, not filing a document. No named client is listed.

What the product had to do

  • Make capture cheap: a plus button and tags on Notes, with a reminder attached to the note.
  • Show what rings next on Today — countdown to the next reminder, plus today’s and tomorrow’s notes.
  • Search notes, tags, and folders in the user’s own words, including voice input.
  • Keep Today, Notes, and Find in one app, with Settings as a fourth tab.

Challenge

Notes, alarms, and search usually live in three apps. A thought dies in a camera roll or a locked note. Retrieval had to feel like asking a person, not filing a document.

RR Tech's solution

Four tabs in a production app: Today, Notes, Find, Settings. Capture is cheap — a plus button, tags, and a reminder attached to the note. Today surfaces the next ring and the day’s list. Find is a search box with voice and filters across titles, tags, and notes.

Architecture and technology

Published stack: Kotlin, AI, Cloud. RR Tech’s Android work is Kotlin-first; this case study does not separately name iOS or a store.

Reminders sit on notes and surface on Today. Find is a search box, not a folder tree. That is product NLP as described — not a named foundation-model brand.

Cloud is listed; hosting provider and model vendor are not. We do not invent them.

Capture paths documented: text, voice, tags, priority.

Four tabs in production

Today

Next-reminder countdown, today’s and tomorrow’s notes, and a capture bar. This is the first screen, not a buried reminders list.

Notes

Tagged notes with Work, Personal, and Health filters, reminder bells, and a plus button to add a note.

Find

Search your notes with voice input, filters, and recent notes across tags — not a folder tree.

Settings

Shipped as the fourth tab. Extra settings behaviour is not documented on this site.

How it was built

The published timeline is 6 weeks, status in production. The documented approach is four tabs and cheap capture, then reminders on notes and plain-language search. Studio phases remain Discover, Design, Build, and Launch. No sprint diary is published.

Results

Write a thought once — get reminded, or find it by asking

  • Today hub with next-reminder countdown and upcoming notes
  • Notes with Work, Personal, and Health tags, plus reminder bells
  • Find search across notes, tags, and folders in one place

Status: in production. Outcomes are the Today hub, tagged notes with reminders, and Find search. No user counts, accuracy metrics, or revenue figures are published.
