Show HN: Float – What if Slack worked like Claude Imagine? (dynamic inboxes) (website.float-chat.com)

Claude Imagine generates software dynamically - no predetermined code, just adapts to what you need. That made me ask: why doesn't Slack work this way?

Slack forces predetermined channels. You join #marketing, now you get pinged about everything from brand strategy to pizza parties. The structure is static, your work context changes constantly.

THE PROBLEM: I was drowning in 50+ channels, checking Slack 60+ times daily. Tracked my time: 2.5 hours/day just PROCESSING messages, not working.

WHAT I BUILT: Float applies the "Claude Imagine philosophy" to Slack: - AI creates dynamic inboxes based on YOUR workflow (not predetermined channels) - "Customer Fires" surfaces urgent threads across all channels - "Deep Work FYIs" batches non-urgent updates - Keyboard-first: every action <2 keystrokes

HARDEST PART: Training ML to understand context, not keywords. Early version grouped "customer churn" with "ice cream churn." Ended up training on 500+ Slack workspaces to learn real urgency patterns: - "@channel" in #general at 11pm ≠ urgent - "@channel" in #incidents at 11pm = wake everyone - Message hierarchy + temporal context = Claude-level reasoning for notifications

Process 50 channels in 10 minutes instead of 2 hours.

Feedback wanted: - Does the dynamic inbox concept resonate? - What's missing for your workflow?

If Claude Imagine is the future of software, Float is the future of comms tools.
