Serendipity Engine

Connections you
didn't know existed.

Every time you save a thought, EIDETIC silently searches your entire vault for related ideas. When it finds a connection, a golden banner appears — linking today's insight to something you wrote weeks ago.

Smart Reminders

Write it down.
Never forget it.

EIDETIC reads your notes as you type. When it detects a time or date, it offers to create a reminder automatically — no separate app, no switching context. Just write naturally.

"Privacy without compromise." No account. No password recovery. No data on our servers. If you lose your device, the vault is gone — by design.

Security Architecture

Built for people who
actually care about privacy.

Every layer of EIDETIC was designed with one principle: your data belongs to you, and only you.

🔐
AES-256 at Rest
SQLCipher encrypts the entire database. The 256-bit key is generated with a CSPRNG and stored in the iOS Secure Enclave.
📵
Zero Cloud
No server, no account, no backup. EIDETIC never connects to the internet. There is nothing to breach, because there is nothing to find.
🧠
On-Device AI
Qwen 2.5 3B runs locally via Metal GPU. Your queries and memories never leave your phone — not even for AI processing.
🛡️
Face ID Always
Biometric lock activates every time EIDETIC goes to background. Your vault is sealed the moment you switch apps.
⚰️
No Recovery
Forget your PIN? Lose your device? The vault is permanently inaccessible. This is not a bug. It is the guarantee.
🔬
Zero Analytics
No crash reports, no usage analytics, no telemetry. EIDETIC is blind to what you do with it.
