3 use cases

  • Recall what you finished and where you left off

    Search a private timeline of yesterday's foreground work to pick up unfinished tasks.

    View prompt
    Using the OpenHistory search in the app, find the most recent activity about <task name> and list the last state of that work in three bullet points. Verify each bullet against a timeline item that shows its date and time before you report it.

  • Let a local coding agent list your unfinished work

    Connect a local agent to OpenHistory's read-only MCP tools to surface open tasks.

    View prompt
    Connect to the OpenHistory MCP server at http://127.0.0.1:47831/openhistory/mcp using the bearer credential from the copied prompt. List the unfinished work from the last <number> days as a short checklist with the source timeline item for each entry, and verify that every entry has a timeline item reference before you report it.

  • Audit and scrub recorded history before sensitive work

    Review what OpenHistory keeps, scrub protected events, and delete local data when needed.

    View prompt
    In the openhistory repository, run the privacy scrub against the local activity data directory at <path> and report how many protected events were removed. Verify the output reports the scrub finished before you state the result.

Quick start with Openhistory

  1. Check you have what it needs: A Mac running macOS 14 or later; Accessibility permission for OpenHistory in System Settings (needed for richer context); For building from source only: Node.js 22 and Xcode with Swift 6.1 or later.
  2. Open ztratar/openhistory on GitHub and read the README and license.
  3. Download OpenHistory for Mac from Openhistory.sh, or build it from source with git clone https://github.com/ztratar/openhistory.git.
  4. On first launch, accept the privacy notice and choose Apple On-Device, a cloud provider, or Summaries off.
  5. Open Settings, choose Grant access, and allow OpenHistory in macOS Accessibility.
  6. Work normally, then open the timeline and check the hourly and daily recaps for the day.

These steps come from our top use case, Recall what you finished and where you left off, which also has a copy-paste agent prompt.
