The local-first second brain for deep work.
Replace passive note graveyards with domain-specific execution cockpits powered by sub-2ms local SQLite.
VAULT:local_vault.sqlite● 1.2msMorning Deep Work Protocol
3 active cognitive blocks
Most note apps are passive filing cabinets for abandoned thoughts. You spend hours organizing folders and zero time executing. Karion replaces blank documents with high-velocity execution cockpits.
Cognitive Friction Benchmark
Capturing and digesting a fleeting thought during deep work
- 1. Switch application window, breaking active mental flow
- 2. Browse or create nested folder structure
- 3. Create new blank document and format title
- 4. Wait 500ms+ for cloud database sync synchronization
- 1. Trigger global hotkey ⌘⇧P without leaving editor
- 2. Type fleeting thought directly into atomic buffer
- 3. Hit Enter: instant synchronous commit to local SQLite
- 4. Modal automatically dismisses in 0ms; flow preserved
The Second Brain Operating Flywheel.
Unlike static note apps that dead-end in forgotten folders, Karion unites capture, digestion, distillation, execution, calibration, and resurfacing around a single sovereign memory hub.
Synthesize highlights into portable, durable mental models and compiled LLM prompt context.
Four purpose-built stages. Zero cognitive drag.
Ideas flow seamlessly from raw capture buffer to structured distillation and daily execution.
Split-Second Distraction Buffer
Park random thoughts into an atomic local SQLite queue in under a second via ⌘⇧P.
3-Stage Media Digestion
Convert raw YouTube transcripts, RSS feeds, and technical articles into synthesized mental models.
Distillation & Prompt Compiler
Compile active highlights into structured prompt payloads ready for local Ollama, Claude, or GPT models.
