Most note apps are graveyards. ClarityOS is a personal knowledge operating system — a structured pipeline that forces your ideas from capture through to finished output. No cloud. No subscriptions. Your data, your disk.
A short walkthrough — what ClarityOS is, and how raw capture moves through the pipeline to finished output.
Ideas arrive. You jot them down. They sit. Rot. Die. The average note app is a place where thinking goes to linger, not to leave.
A note without a destination is noise.
ClarityOS enforces a 5-stage methodology: Capture → Reflect → Synthesize → Execute → Output. Each stage has explicit entry criteria and forcing functions that prevent accumulation without processing.
Frictionless feed with prefix detection, auto-aging (amber at 24h, red at 48h), and quick capture from anywhere.
Insight Notes with a Three-Gate Filter. Each note must prove its value before it’s allowed to survive.
Connection Notes bridge insights. Auto-detect Maps of Content when 3+ connections share a tag.
Max 7 projects. Sprints. Build Logs with auto health detection. Start Smart Wizard.
Content Dashboard, Calendar, Content Banks (hooks/frames/stories), and Performance Logs.
Plain markdown files with YAML frontmatter. No cloud. No sync. No subscriptions. Your vault lives entirely on your machine.
Not just another editor. A 5-stage pipeline with forcing functions. Every note has a job: to move toward output.
Max 7 active projects. Max 3 daily priorities. Constraints that force prioritization. No feature bloat.
Force-directed graph view of your entire vault. See how ideas connect across domains.
Native Windows desktop and Android apps over one vault. Capture on your phone, process at your desk. Everything stays in sync. macOS & iPhone coming soon.
Optional bidirectional sync via Cloudflare R2 with Argon2id + XChaCha20-Poly1305 encryption. Your key, your data.
