Quick Start

1

Install the App

Install the Slack app in your OMI mobile app
2

Authenticate

Authenticate your Slack workspace (one-time setup)
3

Select Default Channel

Choose a default channel (optional - you can specify in voice)
4

Start Messaging

  • Say: “Send message to general saying hello team!”
  • Say: “Post in marketing that the campaign is live”
  • Say: “Slack message to random saying great idea!”

​
Trigger Phrases

  • “Send Slack message” - “Send Slack message to general saying…”
  • “Post Slack message” - “Post Slack message in marketing that…”
  • “Post in Slack” - “Post in Slack to random saying…”

​
How It Works

The app intelligently processes your voice commands:
  1. Detects trigger phrase → Starts collecting
  2. Collects up to 5 segments OR stops if 5+ second gap detected
  3. AI extracts:
    • Channel name (fuzzy matches to your workspace channels)
    • Message content (cleaned and formatted)
  4. Fetches fresh channel list automatically (new channels work immediately!)
  5. Posts message to Slack
  6. Notifies you with confirmation!
Example Workflow:You: “Send Slack message to general saying hello team”
[collecting segment 1/5…]You: “hope everyone is having a great day”
[collecting segment 2/5…]
[5+ second pause - timeout!]
→ AI processes 2 segmentsAI Extracted:
  • Channel: #general
  • Message: “Hello team, hope everyone is having a great day.”
→ Message sent!

​
Using the App

​
With OMI Device

  1. Install the Slack app from the OMI App Store
  2. Authenticate your Slack workspace
  3. Select a default channel (optional)
  4. Say: “Send message to general saying hello team!”
  5. Wait for AI processing (happens silently)
  6. Get a notification with confirmation!

​
AI Processing

The app uses OpenAI for intelligent processing:
  1. Channel Matching - Fuzzy matches spoken channel names to workspace channels
  2. Message Extraction - Extracts clean message content from voice segments
  3. Cleanup - Removes filler words, fixes grammar, proper formatting
Example Transformation: 
"to general saying um hello team hope you're all um doing great today"

​
How Segments Work

OMI sends transcripts in segments as you speak. The app:
  • Detects trigger phrase (Send Slack message / Post Slack message / Post in Slack)
  • Collects up to 5 segments MAX
  • Processes early if 5+ second gap detected (minimum 2 segments)
  • Silent during collection (no spam)
  • AI processes all collected segments together
  • One notification on completion
Smart Collection:
  • Max segments: 5 (including trigger)
  • Timeout: 5 seconds of silence → processes immediately
  • Minimum: 2 segments (trigger + content)
  • Duration: ~5-20 seconds depending on speech
  • Auto-refresh: Fetches latest channels every time (new channels work immediately!)

​
Channel Management

​
Specifying Channel in Voice

You can always specify the channel in your voice command:
  • “Send message to general saying hello”
  • “Post in marketing that campaign is live”
  • “Message to engineering about the bug fix”
AI will fuzzy match to your workspace channels!

​
Using Default Channel

Set a default channel in settings, then just say:
  • “Send message saying quick update for everyone”
  • Message goes to your default channel

​
Refreshing Channel List

The app automatically fetches fresh channels every time you send a message, so new channels work immediately without manual refresh! You can also manually refresh:
  • Click “Refresh Channels” button on homepage
  • Or re-authenticate to get latest channels

​
Switching Workspaces

Click “Switch Workspace” to:
  • Connect to a different Slack workspace
  • Re-authenticate with new team
  • Switch between multiple workspaces easily

​

  • OAuth 2.0 authentication (no password storage)
  • Tokens stored securely with file persistence
  • Per-user token isolation
  • HTTPS enforced in production
  • State parameter for CSRF protection
  • Secure scopes: minimal required permissions

​
Troubleshooting

  • Complete the Slack OAuth flow

  • Visit the app homepage
  • Select a default channel OR
  • Specify channel in voice command
  • Verify channel exists and bot has access
