Notate
ACTIVEAnnotate anything for humans and their agents
Launched July 27, 2026
About Notate
Notate is a free, open‑source macOS menu‑bar app that lets you annotate anything on your screen. It captures frozen frames or timelines, lets you add numbered pins, arrows, shapes and export the results as markdown for agents or as images with comments embedded.

Capabilities
Freeze the screen
Capture a static frame instantly—including open menus, hover and focus states—while preventing underlying changes.
Record frames
Create a timeline of frames, scrub through them, and annotate any point in the sequence.
No tools (gesture‑based annotation)
Add numbered pins, arrows, ellipses, rectangles and lines through simple clicks and drags; shapes snap cleanly.
Agent‑ready exports
Export annotations as markdown that agents can act on, or as images with comments merged.
Honest dedupe
Identical frames collapse into gap markers without losing data, keeping the capture strip truthful.
Smart crop
If all annotations fall within a single window, the export automatically crops to that window instead of the full desktop.
Reopenable sessions
Save each annotation session as a portable .notate archive that can be reopened and continued later.
