Summary

It is Windows desktop only, controlled by a toggle and admin policy, with data processed locally and not sent to Microsoft.
More information
Updated September 9, 2025: We have updated the timeline. Thank you for your patience.
Introduction
Microsoft Edge is introducing AI-powered History search to help users rediscover previously visited sites more easily. This enhanced experience uses an on-device model to understand synonyms, natural language, and minor typos—making it easier to find what you’re looking for. The model is trained locally using your browsing data, which never leaves the device or is sent to Microsoft.
This message is associated with Microsoft 365 Roadmap ID 495834.
When this will happen
General Availability (Worldwide): We will begin rolling out in late September 2025 (previously late August) and expect to complete by late October 2025 (previously late September).
How this will affect your organization
This feature is controlled by the “Enable History search assisted with AI” toggle in Edge settings. Once rollout is complete, the toggle will be on by default.
- After users open their History hub (via Settings and more “...”, then History, or by visiting edge://history), all subsequent website visits will be eligible for semantic search.
- Users will be able to search their history using synonyms, natural language phrases, and minor spelling errors.
Admins can manage AI-enhanced search in their browsing history in Microsoft Edge behavior using the EdgeHistoryAISearchEnabled policy.
- If the policy is enabled or not configured, AI-powered search is available.
- If the policy is disabled, users will only be able to perform exact match (verbatim) searches.
Known limitations at launch:
This feature will be available on Windows desktop only. There may be mobile parity gaps and unsupported environments on other platforms.

No admin action is required before rollout. However, we recommend:
- Reviewing your current Edge policy configurations.
- Notifying users about the new search experience.
- Updating internal documentation as needed.
