About

Reflect Open

Features
Read full description

Reflect Open is a local-first note-taking app for daily notes, linked thinking, and private AI over your own files. Start each day in a daily note, capture meetings, ideas, tasks, and journal entries, then connect people and projects with wiki-style links. Reflect builds a personal graph from ordinary Markdown files, with fast search, backlinks, and optional semantic search that runs on-device. Your notes stay yours. Reflect has no account, no telemetry, and no Reflect-hosted cloud service. Notes are stored as plain Markdown in a folder you choose, with a rebuildable local SQLite index beside them. Optional AI chat, transcription, and sync features only run when you connect your own provider or storage, and private notes are blocked from external AI calls. Highlights: - Daily notes first, with quick capture into today. - Wiki links and backlinks instead of folders. - Full-text search and optional on-device semantic search. - Optional bring-your-own-key AI chat over your notes. - Audio memos with optional BYOK transcription. - iCloud Drive or Git-based sync using files you own. - Markdown source of truth for long-term portability. - Keyboard-native, minimal interface built for focus.
