Overview

Pieces Timeline is your central workspace in the Pieces Desktop App for accessing all workflow context captured by the Long-Term Memory (LTM-2.7) Engine. Timeline displays a chronological view of your workflow events, including timeline events, single-click summaries, and conversational searches.

All events are organized chronologically from most recent at the top to oldest at the bottom, grouped by day. Each day section can be expanded or collapsed by clicking on it or using the caret icon. You can scroll through your timeline, filter events by type or source, and click any event to view its full content in the main view.

Opening Pieces Timeline

Access Pieces Timeline from the main view to see all your workflow events and summaries.

Click the `Show Timeline` button in the top left of the main view if Pieces Timeline isn't already open. The Pieces Timeline opens on the left side, showing all your workflow events organized chronologically. Click `Show Timeline` again to close Pieces Timeline and return to the main view.

Understanding Timeline Contents

Pieces Timeline displays three main types of events, all organized chronologically from most recent to oldest:

  • Timeline Events - Workflow moments captured by LTM-2.7, including code changes, document edits, and other activities from your connected applications. Timeline Events also include automatically generated summaries that capture your work patterns, such as Day Recap, Morning Brief, Week Recap, and What's Top of Mind. These events compile what you've been working on, conversations you've had, and activities you've completed.

  • Single-Click Summaries - Summaries you generate on demand by clicking summary cards on the homepage, including Standup Update, Custom Summary, AI Habits, and more. Once generated, they appear as Timeline Events in your timeline.

  • Conversational Searches - Chat conversations you have with your memories. Each conversation appears as an event in Pieces Timeline, allowing you to revisit past conversations and their context.

Viewing Queued Summaries

When you generate single-click summaries, they appear under the current day in Pieces Timeline with a "Queued" status. Summaries are organized by day, and you can expand or collapse each day to view its contents.

Click `Show Timeline` in the top left of the main view to expand Pieces Timeline if it's not already open. The current day section appears at the top of Pieces Timeline, below the `Filter Timeline` search bar. It shows the date (e.g., "Today, Jan 21st") with a count of items. Click on the current day section to expand it and view all summaries, timeline activities, and other events for that day. Queued summaries appear under the current day with a "Queued" status indicator. You can see which summaries are waiting to be processed and their position in the queue (e.g., "Queued (#3)", "Queued (#2)", "Next in queue"). Click the `caret icon` (dropdown arrow) at the top of the day divider to collapse the day section and hide its contents.

Once summaries finish generating, they remain in the day section where they were queued. You can click on any summary to view its full content, whether it's queued, processing, or completed.

Viewing Event Content

Click any event in Pieces Timeline to view its full content in the main view panel.

Click any event in Pieces Timeline—this can be a timeline event, summary, or conversational search. The event's full content opens in the main view panel on the right, replacing the homepage view. Use the left and right arrow buttons in the event header to navigate to previous or next events without returning to Pieces Timeline. Click the `home` icon or close the event view to return to browsing Timeline Events.

Managing Event Groups

Events in Pieces Timeline are automatically grouped by day, making it easy to find activities from specific time periods.

Understanding Day Groups

Events are organized into collapsible groups labeled by date:

  • Today - Events from the current day
  • Yesterday - Events from the previous day
  • [Date] - Older events grouped by specific dates (e.g., "Jan 14th")

Each group header displays the date and a count of events in that group (e.g., "Today, Jan 15th (2)").

Collapsing and Expanding Groups

Organize your Timeline view by collapsing groups you don't need to see.

Find the date group header you want to collapse (e.g., "Yesterday, Jan 14th"). Click the group header to collapse it. The group collapses, hiding all events within it. Click the collapsed group header again to expand it and view all events.

Jump to Summary in List

Quickly navigate to a specific event's position in the Timeline sidebar when viewing its content.

Click an event in Timeline to view its content in the main view. Click the `Jump to Summary in List` button (target icon) next to the `Filter List` button in Pieces Timeline header. This scrolls Pieces Timeline to show where the current event appears in the chronological list. Alternatively, click the `collapse` button to collapse all event groups at once, giving you a compact view of all dates.

Filtering Timeline Events

Filter your Timeline to focus on specific event types, sources, or applications. Use the Filter List button to access all filtering options.

Learn how to filter Timeline events by type, source, application, and favorites to find exactly what you need.

Event Actions and Menus

Different event types have different actions available through the three-dots menu. Conversational searches have the most options, while summaries have simpler action sets.

Learn how to favorite events, generate titles and summaries, delete events, and understand which actions are available for each event type.
