How to Collect Anonymous Feedback in Slack
Apr 22, 2025
OpenCulture makes it easy to run anonymous Q&A or feedback loops right inside your Slack workspace. Here’s how it works:
Step 1: Install the App
Head over to OpenCultureBot.com and click the “Add to Slack” button.
No permissions? Ask your Slack admin to install it for your workspace.
Step 2: Enable Anonymous Feedback in a Channel
Use the slash command: /enable_qna
This activates anonymous feedback collection for that channel. You can configure moderation settings and choose whether you want AI-based review, human moderation, or both.

Step 3: Invite Anonymous Feedback
Once enabled, anyone can submit feedback using: /ask_qna
This opens a private modal where the person types their feedback. No names attached. No paper trails.

Smart Features That Make It Even Better
Duplicate Detection: Finds similar questions or feedback already asked and nudges the person before submitting again.
Moderation Options: Choose AI moderation, human reviewers, or a combo. Keep things respectful and relevant.
Private Replies: Moderators can respond privately to feedback if needed, either anonymously or identified.
Responder Tagging: Assign team members as designated responders, so feedback isn’t just collected — it gets answered.
Optional Weekly Reminders: Gently remind your team that anonymous feedback is open and encouraged.
Alternative Approach: Build Your Own Slack Bot (But Should You?)
Could you build an anonymous feedback bot yourself using Slack’s API? Technically, yes.
But here’s what you’d need to handle:
User identity masking
Moderation and abuse prevention
Data privacy compliance
UX around duplicate detection and response flows
If that sounds like a lot of work (it is), OpenCulture handles these tricky parts out of the box.

Final Thoughts
When done right, anonymous feedback is not about letting people hide — it’s about giving people the confidence to speak. The hard questions? The uncomfortable truths? Those are exactly the conversations that help your team grow.
OpenCulture helps you bring those conversations into the light — safely, respectfully, and productively.
