Hivemind: turning a whole event into one collective thought
Hivemind was built for an in-person AWS hackathon. Every attendee could send in a single word from their phone. We funneled those words into a central “brain” that periodically generated a single sentence describing what the whole crowd was thinking.
A Lambda function writes each word into Couchbase. Another Lambda periodically grabs a random subset of those words, feeds them to Amazon Bedrock, and renders the resulting “hive thought” on the main event screen so the room can literally see its collective mood.
Live event brain
Everyone sends one word. The screen shows one mind.
Inputs from hundreds of attendees are sampled, remixed via Bedrock, and surfaced as a single animated thought on the main display.
Sample hive output
“We're a room full of builders, running on caffeine, hoping the demo gods are kind.”
How it works
- 1. One-word input: each attendee submits a single word from a simple web form.
- 2. Lambda → Couchbase: an AWS Lambda function writes the word, user/session metadata, and timestamp into Couchbase.
- 3. Sampling the hive: a scheduled Lambda grabs a random subset of recent words to avoid the same few people dominating the feed.
- 4. Prompting Bedrock: the words are turned into a compact prompt and sent to Amazon Bedrock, which generates a short “hive thought.”
- 5. Main-screen render: the thought is pushed to the event display as a glowing banner that updates periodically as more people submit.
