How to remember what you worked on last week

Updated September 2026 · by Jerry Liu, Dayflow's founder

To reconstruct last week, start with records you already have: your calendar, completed tasks, documents, commits, and sent messages. Use them to build a dated list, then check which items were finished and which were still in progress.

An automatic work journal can make future reviews easier, but it cannot recover days before it was running.

Reconstruct a week in three passes

  1. Find the main projects. Scan your calendar and task tracker for the week. Put each project under a day, leaving uncertain dates marked as approximate.
  2. Add supporting work. Check document history, reviews, and sent messages for work that did not become a completed task. Include relevant calls and offline work from your notes.
  3. Verify outcomes. Link to the finished document, merged change, or decision. Keep time spent separate from results delivered.

Use a simple format: date, project, work done, outcome, and a link to the source. For an invoice, confirm the hours and billing rules separately. A remembered activity is not an approved time entry.

Keep a record for next time

Dayflow records your Mac’s screen and uses AI to draft a timeline of your activity. That can give you somewhere to start when you need to remember which project occupied an afternoon.

Review the timeline before relying on it. Screen activity can be misinterpreted, and conversations away from your computer need to be added from another source. Full recordings and the local timeline stay on your Mac; Local AI keeps screenshot analysis on-device, while cloud modes receive selected screenshots for analysis.

Adapt the record to its audience

For a performance review, select work that demonstrates an outcome and link to evidence. For a standup update, keep only the progress, next steps, and blockers your team needs. For a personal weekly review, compare the record with your plan.

If you need project rates, invoices, or synced billing entries, read the Memtime comparison before choosing a personal journal. Dayflow does not replace those billing tools.

Keep the detailed record private. Share a reviewed summary with only the information the recipient needs.
