Sile — Your mind, encrypted.
A private, AI-powered second brain where your thoughts stay yours. Every note is encrypted with AES-256-GCM before it touches disk. No cloud. No accounts. No telemetry on your content. Ever.
ENCRYPTED NOTES
Write freely with a rich Markdown editor — bold, italic, headings, lists, checklists, and code blocks. Everything is encrypted at rest with military-grade AES-256-GCM encryption. Your notes never exist as plaintext on disk.
VOICE TRANSCRIPTION
Record voice notes and get instant on-device transcription. Perfect for capturing ideas on the go, meeting notes, or brainstorming sessions. All processing happens on your device — nothing is sent to any server.
DOCUMENT SCANNER
Scan documents with your camera. Automatic edge detection, perspective correction, and on-device OCR extract text from any document. Multi-page scanning support for longer documents.
AI INTELLIGENCE — 100% ON-DEVICE
Summarize notes, extract actionable tasks, auto-suggest tags, and chat with your notes — all powered by on-device AI. Zero network calls. Your content never leaves your phone.
CONTRACT ANALYZER
Analyze legal documents and contracts for key terms, obligations, and potential red flags. Get clear, structured breakdowns of complex legal language — all privately on your device.
HEALTH JOURNAL
Track your mood, symptoms, sleep, energy, and medications. View patterns over time with a beautiful calendar view. AI-powered insights help you discover correlations in your health data.
VAULT
Store sensitive files, images, and documents in an encrypted vault with dual-layer security — biometric plus PIN protection.
ORGANIZE YOUR WAY
Folders, tags, pin, archive, favorites, and full-text search across all your encrypted notes.
BIOMETRIC LOCK
Protect your notes with Face ID, Touch ID, or a secure PIN. Your privacy is non-negotiable.
BEAUTIFUL DESIGN
Warm, intimate design inspired by a leather notebook in a private library. Dark and light themes included.
