Introduction to Workstream Activity

Overview

The Workstream Activity view in the Pieces Desktop App integrates with the new-and-improved Long-Term Memory Engine (LTM-2) to capture and summarize your recent tasks, discussions, code reviews, and more.

By automatically generating concise roll-ups of your workflow, Workstream Activity aims to eliminate the repetitive context-setting required by most AI tools.

LTM-2—also referred to as Long-Term Memory Engine—is available as part of PiecesOS, which is required for the Pieces Desktop App.

Make sure you have the latest versions installed to take advantage of this feature.

Main View

Once you access Workstream Activity, you’ll see two main UI elements:

Activity Sidebar (Left Panel): A chronological list of your LTM roll-ups. Each roll-up is timestamped (e.g., “9:04 AM – 9:14 AM”) with a descriptive title (such as “Documentation & LTM-2 Prep”).
Roll-Up Details (Right Panel): Selecting a roll-up displays its sections and bullet points, including embedded links, references, or code snippet IDs.

Long-Term Memory (LTM-2) Engine

Long-Term Memory is an advanced memory agent that captures your workflow context at repeated intervals and preserves it for up to nine months.

Instead of starting fresh with every AI query, you can use LTM-2’s persistent memory to pick up any past conversation, code snippet, or link you’ve encountered.

LTM Roll-Ups

Each roll-up is a one-page summary that includes information and specific sections, such as:

Core Tasks & Projects: A concise, but rich overview of projects, tasks or specific initiatives you’ve worked on—including problems and solutions (and how you came to that solution).
Key Decisions & Discussions: Important conversations or choices you made, mentioning with whom you had discussions or meetings or who shared critical details that had implications on your workflow.
Documents & Code Reviewed: References to any files, articles, or snippets you accessed, often deep-linked with clickable URLs (where applicable).
Follow-Up Actions: Unfinished items, suggestions for next steps, and reminders.

Interacting with LTM Roll-Ups

Each roll-up offers multiple interaction points:

Start Copilot Chat: Immediately open a Pieces Copilot Chat session scoped to that roll-up’s context, eliminating the need to re-explain your background or goals.
Copy / Download: Export the roll-up as plain text or Markdown, letting you archive or share your summary outside of Pieces.
Deep Links: Open references directly in your browser. If the roll-up mentions a specific blog or document, you can jump straight to it from within Pieces.

If you remember that a teammate shared a solution link last month, you can locate that exact snippet, conversation, or link by searching the relevant keyword in Workstream Activity.

Use Cases

Workstream Activity turns your daily work into a rich, queryable memory—so you never have to waste time re-explaining, re-documenting, or retracing your steps.

Why use the Workstream Activities feature?

The Workstream Activity feature centralizes your workflow context, tackling a major productivity blocker in AI-assisted development—short-term memory.

It eliminates the need to repeat information to an AI assistant, ensures project continuity, provides a powerful search for past discussions or documents, and allows flexible exports for sharing or storing roll-ups.

With support from the LTM-2 engine, it becomes easy to search, share, and summarize critical moments from your workflow.

Here are some practical ways to use it:

Create Context Packs for Onboarding New Team Members

Build AI-Ready Summaries for Async Standups and Check-Ins

Generate Internal Documentation from Real Workflows

Recover Forgotten Context After a Break

Audit Past Decisions and Review Rationale

Track Research and Learning Progress Over Time

Privacy & Source Control

Your data is yours to manage.

At any time, even after a summary has been generated, you can disable sources from which LTM captures workflow data. Since LTM is available for use outside of the Pieces Desktop App, there are two locations from which you can make these changes.

In the Workstream Activity view, there is an LTM Access Control modal designated by a grid-like icon—clicking this opens the modal, where you can toggle or un-toggle data capture from specific sources.

In the PiecesOS task bar window, you can disable any sources you don’t wish to capture (e.g., personal browsing activity or data from messaging applications) through the LTM Access Control panel.

Events gathered from disabled sources will be removed from your roll-ups so they don’t appear in Workstream Activity or Pieces Copilot Chats.
