Slack Brilliant Bot
Trusted by 2,000+ workspaces with 550,000+ team members
For Employees & Team Members
Speak Truth to Power Without Social Anxiety
Have an insight that challenges team consensus? Noticed a critical bug or architectural flaw that everyone else is ignoring? Want to ask an honest question in a company-wide channel without feeling self-conscious?
- Tag your intent: Categorize posts with 💡 Idea, 🚩 Concern, 🤔 Question, or 🏆 Praise.
- Thread Pseudonyms: Join back-and-forth debates with randomized avatars (OP, Anonymous 1).
- Show your department: Display verified Slack usergroup badges (e.g.
[Engineering]) without revealing your personal identity.
For C-Levels & HR Leaders
Pierce the Executive Echo Chamber & Test Ground-Level Reality
When a CEO or VP asks a question publicly in Slack, people panic or offer polite non-answers. OpenSay allows leadership to gauge frontline sentiment and ask questions anonymously as an everyday peer without the executive title skewing the response.
- Pose Inquiries as a Peer: Float hypothetical questions or test team readiness for roadmap changes without leadership presence chilling the room.
- Automated AI Guardrails: Google Perspective API and LLMs filter toxicity, profanity, and PII before messages post.
- Community Karma & Flagging: Self-regulating threshold moderation ensures high-quality discourse.
- Channel Whitelisting: Confine anonymity to dedicated channels (
#ask-the-execs,#product-feedback).

OpenSay in Slack vs. External HR Portals
Why in-Slack feedback eliminates portal friction compared to HiBob, Lattice, or Google Forms.

|---|---|---|
| Where it Happens | Directly in Slack (where work already occurs) | Separate web app login (rarely opened) |
| Employee Anonymity Trust | Zero Author ID Storage & Cryptographic Hashing | Employees fear internal corporate IT tracking |
| 1-on-1 Pulse Surveys in DMs | Yes (instant confidential DM surveys) | Long external email links |
| AI Toxicity & PII Filtering | Real-time Pre-Flight AI Perspective Verification | None or basic keyword blacklist |
| Interactive Thread Pseudonyms | Yes (random avatars maintain discussion flow) | Static one-off text boxes |
| Verified Usergroup Badges | Yes (e.g. [Engineering], [Sales]) | All-or-nothing identity |
