Features¶

Calendar views¶

• Week and day calendar:
  • Each session is drawn as bars covering its active periods.
  • A session is split wherever it sat idle longer than the chosen threshold (15 minutes by default).
  • Overlapping sessions sit side by side.
  • Click a date in the week view to open that day on its own.
  • Zoom with the − / + buttons or Ctrl + mouse wheel.
• Month and year views: a month calendar and a GitHub-style yearly heatmap, with one cell per day.
  • Cells are shaded by active time or cost; switch with "Shade by".
  • Month cells list the day's busiest projects.
  • The year view adds per-month totals.
  • Click a day to open it in the day view, or a month total to open that month.
• Colors by project, status, model, effort (the level most requests ran at), source (with several config directories), tag or cost (< \$1 / \$1–5 / \$5–20 / \$20–50 / ≥ \$50).
  • Tag colors a session by its first tag, so put the main one first. Sessions without tags are gray. The button shows once any session has a tag.
• Event marks on each bar show when prompts, commits, compactions and API errors happened.
  • The tooltip counts them for that block.
  • Click a mark to open the transcript at that point.
• Activity density: a heat strip behind each day shows prompts and responses per 10 minutes.
• Live updates: new log lines are picked up within a second.
• Views in the URL: the address keeps the calendar or list view, the span, the date, the selected session and the open project page.
  • Reloading the page keeps your place, and you can bookmark a view.
  • The browser's Back and Forward buttons step through range, span and view changes and the project page. Selecting a session does not add a step.
  • A bookmark shows the same view on any day. A session or project the logs no longer have is left out.

Time, cost and usage¶

• Time and cost totals:
  • Each date shows that day's active time and cost.
  • The Summary table breaks the displayed range down by project.
  • A session's cost is split across days by when its requests ran.

• Markdown report: "Copy report" copies the displayed range as Markdown. The report covers:

  • active time and cost per project
  • each session's title and tags (notes are left out)
  • the commits made in the range

  Issue and PR numbers such as #12 become links to the repository's origin remote. - Tool usage: the Tools pane aggregates tool calls in the displayed range: - most used tools, with error counts and rates - calls made inside subagents - MCP servers - subagent runs by type, with their tokens and cost - Cache efficiency: each session shows its cache hit rate and roughly how much caching saved. Rates below 90% are highlighted.

Sessions in detail¶

• Status:
  • Running and Waiting for live sessions; Done or Interrupted for finished ones.
  • The underlying checks are shown: turn ended, no background work left, clean exit and working tree clean.
• Notifications:
  • Turn on "Notify" in the top bar. The browser asks for permission the first time.
  • You get a desktop notification when a live session goes from Running to Waiting for your input, or ends Interrupted.
  • Notifications are sent only while the cc-calendar tab is in the background. Click one to open that session.
  • Off by default; the setting is remembered in this browser.
• Detail pane shows:
  • tokens, cost and context usage
  • every request you made, with the commits that followed it
  • files changed and pull requests
  • subagents and background tasks
  • links between a session and the one it was continued in
• Notes and tags: the Notes card in the detail pane keeps a note and tags for the session. Click + Add note or tags to start.
  • The note is plain text, up to 2,000 characters. It saves when you leave the box, with Cmd+Enter / Ctrl+Enter, or with Esc.
  • Type a tag and press Enter or a comma to add it; tags already in use are suggested. Click ✕ on a tag to remove it.
  • Tags that differ only in case count as one, written the way they were first used.
  • The list view has a Tags column and a Tag filter, including "(untagged)". A 📝 next to a title marks a note; hover it to read the start.
  • The calendar tooltip shows the tags, and the search box matches notes and tags.
  • They are saved in a file of their own; see Notes and tags for where.
• Resume: "Copy resume command" copies cd <project dir> && claude --resume <session id>. Paste it into a terminal to pick the session up again. Claude Code looks sessions up by the directory they were started in, so the command changes to that directory first.
• Effort and compactions:
  • The share of requests at each effort level.
  • Each compaction's trigger and context size before → after, e.g. auto · 168k → 32k tokens.

• Transcript viewer:
  • Markdown rendering and collapsible tool calls.
  • Optional thinking and metadata.
  • Drill-down into subagent transcripts.
  • A stats panel per transcript.
  • ‹ › buttons to step through prompts, commits, compactions and errors.
• List view:
  • Search over titles, prompts, notes and tags.
  • Filter by project and status.
  • Narrow the list further by model, git branch, source (with several config directories), tag, date range and cost range. The date range keeps sessions that were active on any day in it. These filters apply to the list only; Clear resets them.
  • Sort by any column.

• Project page: click a project name to open it. Project names can be clicked in the list, the Summary table, the detail pane, and the project menu (Page). The page covers all time and ignores the filters. It shows:

  • total active time, cost, sessions, prompts, tokens and commits
  • active time, cost, sessions and commits per month
  • every session of the project; click one to open its details
  • the commit history, newest first, with links to the commits on GitHub or GitLab

  ← Back or Esc returns to the calendar or list.

• Export: download the sessions shown in the list view as CSV or JSON. The file follows the current filters and sort order. It covers:

  • start and end (ISO 8601 with your UTC offset) and active time
  • project, source config directory, branch and status
  • prompts, tokens, cost and cache hit rate
  • model, effort, Claude Code version and number of commits
  • tags and note

  See Export format for the fields and the JSON envelope.

Keyboard shortcuts¶

Press ? or click ? in the top bar for this list. Button tooltips show their key too.

Keys typed in a form field go to the field, and only Esc works there. Leaving the search box with Esc keeps its text.

While a transcript is open, these keys work instead:

? shows both lists here too.
