RevSofia, a Car Meetup app that people will love to use

Description and use

RevSofia automates extraction of meet details from group chats using Gemma 4 and publishes approved meets on a static site and Discord with calendar integration.

Problem

Car meets in Sofia are organized via group chats that are hard to parse for details like time, place, participants, and club affiliation.

Outcome

RevSofia automates extraction of meet details from chat, reduces manual effort to ~30 s, and ensures accurate calendar events and Discord announcements.

Workflow

• Paste chat into planner
• Tick "I'm human"
• Click "Draft the meet"
• Gemma 4 parses chat and returns draft meet JSON
• Review and correct any errors
• Click "Send for review"
• Draft becomes a GitHub issue
• Merge issue to approve meet
• GitHub Action posts embed to Discord
• Meet appears on public board and calendar

Evidence

The planner takes that thread, in any language, and asks Gemma 4 (gemma-4-31B-it, an open-weight model) to turn it into a draft meet.

Source

When a meet is approved, it's posted to the Discord automatically, with the time shown in each reader's own time zone.

Source

The meets are JSON files in the repo. A tiny Node build script validates them and spits out the site's data plus one .ics calendar file per meet.
