New features​

Add sketches and notes on a session recording​

Annotations in Multiplayer let you turn raw session recordings into actionable development plans.

Whether you’re fixing a bug, clarifying requirements, or sketching a new feature idea, annotations help capture context directly on the timeline and make it reusable for your team or your AI IDE / AI coding assistant.

  • Go from session replay to development plan: Transform session data into precise, contextualized instructions.

  • Collaborate across roles: Share annotated replays with devs, QA, PMs, or vendors for clear handoffs of new feature requests and suggestions.

  • Supercharge your AI tools: Feed annotated sessions into your AI IDE or copilot to generate code, tests, or feature implementations with minimal prompting.

Annotations feature set​

After you’ve recorded a session, you can enrich it with additional context.

  • Navigate to Sessions
  • Open your desired full stack session recording
  • Navigate to the desired timestamp

For each timestamp you can add multiple:

  • Sketches: Draw directly on the session replay, add shapes and arrows. This allows you to visually highlight the UI elements you want edited or mark problem areas. As a tip, use different colors to communicate different intentions (e.g. red for bugs, green for feature ideas).

  • On-screen text: Add written details to your sketches: explanations of the desired behavior, or what the updated UI text should be.

  • Timestamp notes: Attach one or more notes at specific points in the timeline. These can clarify reproduction steps, mark requirements, clarify design intentions, or simply leave comments for your team.

  • Full-stack context: Because Multiplayer auto-correlates frontend and backend data, annotations can be directly added to your

    • User interactions (clicks, inputs, navigation)
    • API calls (with request/response details)
    • Traces and spans (service-level performance and errors)
    • …

  • General notes: Notes support the same blocks supported by notebooks, including:

    • Text blocks
    • Code blocks
    • Visualization blocks

Pulling sketches and notes into an AI coding tool​

Use the Multiplayer MCP server to pull your full stack session recording screenshots and notes into your AI coding tools.

Each annotation carries its own metadata, ensuring your context is precise, reproducible, and linked directly to the system events it relates to.

Improvements​

We have updated our onboarding wizard and configuration documentation to reflect the versatility of Multiplayer and your customization options.
