AI-native CRM that builds itself and does work for you

Hey Product Hunt!

I built Glance after getting tired of opening editors just to read Markdown files.

Markdown is everywhere now: README.md, CLAUDE.md, AGENTS.md, specs, notes, and AI-generated docs from Claude Code or Codex. But in Finder, .md files are still awkward to preview. You either see raw syntax or need to open Cursor, VS Code, or TextEdit just to read the file properly.

Glance fixes this with a native macOS Quick Look extension.

Press Space on any .md file and get an instant, cleanly rendered preview with clean typography, tables, code blocks, links, images, blockquotes, LaTeX math, and Mermaid diagrams.

It is fully free, works offline, weighs only 8.3 MB, and has zero telemetry.
