Document-grounded Q&A
Members ask questions in any Slack channel and receive answers grounded in the lab's documentation, with source citations to encourage reading the original material.

CHOIR
A Slack assistant that helps teams answer questions from GitHub-backed documentation and turn useful conversations into durable organizational knowledge.
Ask
Find answers from workspace documentation inside Slack.
Capture
Convert valuable discussions into suggested document updates.
Maintain
Apply approved updates back to GitHub markdown files.
System
Four interconnected workflows for organizational memory
CHOIR embeds organizational memory directly in Slack, connecting GitHub-backed documentation with everyday lab communication through four coordinated features.
Q&A Sharing for Follow-up Discussion
After CHOIR responds, questioners can share the exchange publicly or privately — with optional anonymity — to gather peer input or surface knowledge gaps to the director.
Knowledge Extraction from Conversation
Any lab member can summon CHOIR in a Slack thread to extract documentable knowledge from the discussion and send a suggested update to the manager for review.
AI-assisted Document Update
Managers review suggested edits inline in Slack, with diff-style previews and one-click apply — keeping documentation current without leaving the communication platform.
Research · CHI 2026
Studying organizational memory in university research labs
CHOIR was designed from formative interviews with 15 faculty and graduate students, then deployed across four university research labs for one month (n=21). Lab members asked 107 questions and directors updated documents 38 times. Findings reveal a fundamental privacy-awareness tension: students preferred private Q&A, limiting directors' visibility into documentation gaps.
