Annotrail by MakerBi

Annotrail adds a focused annotation sidebar to the browser. Select one or more elements on any supported page, attach a note, keep the history locally, and export structured context as Markdown or JSON for review, QA, research, or LLM workflows.

Key features:
- Select multiple page elements for one annotation.
- Save annotation history locally in the browser profile.
- Review, edit, delete, clear, copy, and export history.
- Export either Markdown for readable handoff or JSON for structured automation.
- Use Chinese or English UI with automatic language detection and manual switching.

Annotrail does not collect analytics, run a remote service, or upload your annotation history.
