Hivemind

turning a whole event into one collective thought

Built at an in-person AWS hackathon. Every attendee sends a single word from their phone. We funnel those words into a central brain that periodically generates a single sentence describing what the whole crowd is thinking.

Lambda writes each word into Couchbase. Another Lambda samples a random subset, feeds it to Amazon Bedrock, and renders the resulting “hive thought” on the main event screen.

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.”

Hive thought generated

We're a room full of builders, running on caffeine, hoping the demo gods are kind.

How it works

from word input to crowd thought

1. One-word input

Each attendee submits a single word from a simple web form on their phone.

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.

4. Prompting Bedrock

Words become a compact prompt, and Amazon Bedrock generates a single "hive thought" for the room.

5. Main-screen render

The thought is pushed to the event display as a glowing banner, updating as more people submit.
