# Casual Note

> A fully-local, privacy-first desktop notebook that unifies notes, reminders, tasks, and AI meeting intelligence into one encrypted, on-device store. No cloud, no account, no telemetry. It runs entirely on the user's machine; the network is used only, and with explicit consent, to download AI models and check for app updates.

Casual Note is *casually a notebook* — notes, tasks, and reminders — that is also a best-in-class local meeting recorder and understander. Four pillars share one encrypted SQLite/SQLCipher store, one search index, one link graph, and one evidence-citing AI workspace. It is built as a Tauri 2 + Rust desktop application with a React/TypeScript UI, using whisper.cpp for on-device speech-to-text and llama.cpp for a local LLM. It is free and open source under Apache-2.0 and targets macOS, Windows, and Linux.

## The four pillars

- **Notes**: a block/Markdown editor with daily notes, `[[wikilinks]]`, `#tags`, backlinks, checklists, and attachments.
- **Reminders**: natural-language entry with recurrence and a dual-layer scheduler that delivers alerts whether the app is open or closed, with catch-up for anything missed.
- **Tasks**: a Things-style planner — Today, Upcoming, Anytime, Someday — with projects and areas; meeting action items flow directly into tasks.
- **Meeting Intelligence**: captures selected-application and microphone audio, transcribes locally, and produces summaries, decisions, and action items with a local LLM, with every fact linked to transcript evidence.
