Agentic Playbook Creation in Assistant
Harvey adds conversational Playbook creation and editing in Harvey Assistant, with a live side-by-side view, playbooks as an Assistant knowledge source, and seamless switching between Assistant and the standard editor for manual updates and governance.
Playbook managers can now create, upload, and edit playbooks directly through Harvey Assistant.
What’s New
Playbook managers can now create, upload, and edit playbooks directly through Harvey Assistant. This update introduces a more flexible, conversational approach to building and maintaining playbooks, reducing the need for manual, form-based workflows. You can now:
- Create and edit playbooks conversationally, with guidance in Assistant
- View a live side-by-side panel during creation to track rules and structure in real time
- Use playbooks as a knowledge source in Assistant for context-aware guidance
- Switch seamlessly between Assistant and the standard editor for manual adjustments and governance
Why It Matters
This release enables your teams to generate high-quality, precise first drafts more quickly and iterate on positions with less effort.
How to Use
Creating and Editing Playbooks with Assistant
Begin in Assistant by describing in natural language the new playbook or updates you’d like to make, or, engage Assistant while editing Playbooks in Settings.
For full how-to steps, refer to Create a Playbook.
Using a Playbook as a Source
When selecting a source in Assistant, you can now add a Playbook.
This can be useful for checking positions (e.g., “What’s our fallback on liability caps?”), or receiving AI guidance on how to understand positions and adjust rules, based on the Playbook.

Batch Document Editing
Harvey adds batch document editing for Word files, letting users apply edits across multiple .docx documents with a single prompt. Related files stay in shared context for easier version tracking and organization, with support for up to 50 documents when Claude-enabled features are on.
Batch document editing lets you make edits across multiple documents at once. Instead of updating each file individually, you can ask Assistant to apply edits to a suite of documents with a single prompt.
Whether you're running batch updates or working across multiple documents, all your related files stay in one shared context — making it easier to navigate versions, stay organized, and keep your workflow moving without losing track of where you left off.
Learn how to get started, use cases, and more in our new article, Editing Multiple Word Documents in Assistant.
Note: Batch Document Editing Word is available for Word (.docx) files only and requires Claude-enabled features to be turned on for your workspace.
FAQs
Q: What types of edits can I run?
You can apply edits such as rewriting, summarizing, clause updates, formatting changes, and issue identification.
Q: How many documents can be edited at once?
You can edit up to 50 documents at once (based on Vault capacity and thread attachment limits), though smaller batches will give you faster, more reliable results.

Client Matter-Level Vault Retention
Harvey adds per-client matter Vault retention, letting admins override the workspace default and set how long vaults are retained for each matter to better match governance needs.
Admins can configure how long Vaults are retained for each client matter.
What’s New
Per-client matter (C/M) vault retention lets admins set how long vaults are retained for each client matter — overriding the workspace default to match the governance needs of every engagement.
- For example, if your workspace Vault retention is 7 days from the last update, but the associated Client Matter is set to 30 days, the vault is retained for 30 days after no activity.
Why It Matters
Retention needs vary by matter. A litigation hold may demand indefinite preservation to pause deletion, or a time-sensitive matter may have comparably short retention. Admins can now configure these policies in Settings, ensuring each matter is handled appropriately.
How to Use
For step-by-step guidance and expanded FAQs, refer to Manage Vault Data Retention Settings.
FAQs
Q: What are the prerequisites for using this feature?
- Your workspace must be using Client Matter Numbers in Harvey
- In Client Matter settings, “Associate vault projects with a Client Matter” must be set to Optional or Required (learn more here)
Q: Who can set custom retention policies for client matters?
Admins only.

View As Collaborator
Harvey adds View As Collaborator in Spaces, letting users preview access and visibility from an external Harvey user or guest account, check resource-level permissions, and adjust sharing settings in real time before or after inviting collaborators.
Preview Spaces from a collaborator’s perspective to verify access, visibility, and permissions before and after sharing.
