The Vibe

• .md is the source of truth. Always. No proprietary databases trapping your thoughts.
• SQLite is an index, not a prison. We use GRDB.swift to make search instant, but your files remain just files.
• The feeling of writing > feature count. It’s about the flow.
• Round-trip safety. We never destroy your manual formatting.
• AI is a silent assistant, not the center of the product.

Key Features

• Line Numbers & Syntax Highlighting: Perfect for the veterinarian/engineer who mixes text with json, swift, python, and rust.
• WYSIWYG-style Preview & Two-Way Links: For structural note-taking and seamless reading.
• Split Modes: SOURCE (Cmd+1), SPLIT (Cmd+2), PREVIEW (Cmd+3), and upcoming FOCUS (Cmd+4).
• Fast Native Core: Built on Swift 5.9+, SwiftUI, and AppKit's NSTextView with TextKit 2.

Background & Heritage

Pensieve is the spiritual successor to an older Objective-C markdown editor (by Satoshi Iwaki) that served as our daily driver for over a year. We kept the essence (and the CSS) but rebuilt the engine entirely in modern Swift to drop legacy debt and gain native Apple Silicon performance.
