Lookback tools let Hana retrieve and consider chat history between two timestamps or for a specified time delta from the current moment. This feature allows you to review past conversations and get answers based on historical context, making it easier to catch up on missed discussions or reference previous messages. Provide the relevant timestamps or time delta, and Hana will fetch the necessary chat history on your behalf.

Conversation Look Back QnA
Over the past three days, the following concerns were raised in this group:
1. Video Upload and Hero Video Update: There was a request to upload a "summer day" video to YouTube and update the hero video with it. This task was acknowledged and agreed upon by the team member responsible.
2. Current Workload and Task Updates: There was a query about the current tasks being worked on, and it was mentioned that work is ongoing on the Hana landing page and reorganizing the Discord channel. A commitment was made to show low-fidelity designs the following day.
3. Content Alignment: A request was made to create a document to align content, which was agreed upon by the team member.
Regarding unresolved concerns, it seems that the tasks mentioned were acknowledged and agreed upon, but there is no explicit confirmation of completion for all tasks. It might be helpful to follow up on the status of these tasks to ensure they are resolved.
- In the above scenario the lookback tool was invoked by Santhosh asking “what are we discussed from start of today and group each by respective involved persons”
