Backsight

Uncover the Patterns You Can't See

Backsight closes the gap between what you feel and what you actually do by turning your notes into statistics over time. It notices the patterns you'd never catch from the inside, providing a mirror for your life without offering unsolicited advice or coaching.

How it Works

1. Speak a moment: Use voice or text to record something the moment it happens. There is no setup required and no specific fields to fill out.
2. On-device transcription: Audio never leaves your device and is deleted immediately after being converted to text, ensuring your data remains private and offline.
3. Your notes become stats: An offline dashboard surfaces patterns like repetition, distribution, spikes, changes, and correlations. It even shows sample size and uncertainty so you don't over-read the results.

Use Cases for Self-Discovery

Instead of re-reading every entry in a journal, Backsight allows you to see what actually drains your energy or impacts your mood across weeks and months.

• Mood and Energy: Identify specific times, like Wednesday afternoons, where your energy consistently shifts.
bsp;
• Correlated Themes: See how themes like work, sleep, or family correlate against your tone and sentiment.
bsp;
• Recurring Themes: Track how often you log certain topics (e.g., logging sleep twice as much as family) to see where your focus lies.
bsp;
• Unknown Unknowns: Discover patterns you never thought to look for, found in what you actually said rather than what you chose to measure.

Privacy and Ownership

Backsight is built on a foundation of extreme privacy and user ownership. Your data stays with you, and the system is designed to't be locked in.

bsp;
• On-device Transcription: Audio is processed locally and deleted immediately.
bsp; bsp;
• End-to-end Encrypted Sync: Notes move between your own devices using keys only you hold.
bsp; bsp;
• Accountless System: No login required; your private keys are your identity.
bsp; bsp;
• Unlimited Export: Access raw CSV or JSON data anytime, never paywalled and never locked in.

Planned for Power Users

For those who want to go deeper, Backsight plans to offer a local MCP server. This allows you to point any agent (like Claude or a local model) at your own data on your own machine without the user ever seeing it.
