Description

Snapperon is a native macOS app for capturing screenshots, annotating images and PDF pages, and preparing clear visuals for documentation, feedback and presentations. Add styled arrows, text banners, numbered steps, highlights, shapes, spotlights, freehand marks and redaction. Finish with backgrounds, borders and watermarks, then use Copy + Close, drag-and-drop, or PNG/JPEG export.

Work by hand or connect Claude Desktop or Codex Desktop through Snapperon’s local Model Context Protocol (MCP) server. Its 18 commands cover all 9 native annotation tools, presentation controls, rendered previews, selective edits and export. Review a staged batch, commit it as one Undo action, then adjust individual layers by hand. Both desktop clients have been tested.

Snapperon requires macOS 14 or later and Apple silicon (M1 or newer). No account is required. Snapperon does not upload screenshots to its servers; a connected AI client may send inspected source images or previews to its provider. MCP controls the installed Mac app locally, not a hosted cloud API. PDF pages are shared as flattened PNG/JPEG visuals; PDF re-export is not offered.
