Features

• E2EE that actually works - mautrix-go with goolm (pure Go). Crypto state lives in SQLite so device keys survive restarts. Cross-signing bootstraps on first run — the bot self-verifies its own device.
• No CGo, no system deps - builds to a single static binary. Cross-compile to whatever you want.
• 38 plugins with dependency injection and ordered registration
• Moderation system (optional) - deterministic detection only, no LLM. Word list with leetspeak variation matching, text/image flood, repeated messages, mention flooding, link rate limiting, invite flooding, join/leave cycling. Three-strike ladder (warn → mute → ban). Admin room notifications, DMs over public callouts.
• Passive tracking - XP, stats, streaks, achievements, markov corpus, keyword alerts, all running silently
• Scheduled posts via robfig/cron - WOTD, holidays, game releases, birthdays, anime/movie releases, concert digests, esteemed members
• LLM integration (optional) - Ollama-powered sentiment analysis, roast profiles, room vibes, tarot readings, conversation summaries
• Encrypted quote wall - AES-256-GCM encrypted quotes at rest, reply-to-save, search, leaderboard
• Space groups - automatic room grouping via membership overlap. Leaderboards, stats, and trivia scores span all rooms in a group. No Matrix Spaces API needed — the bot infers community boundaries from shared members.
• SQLite everything - one file, no external database needed

---

Requirements

• Go 1.22+

Running the Bot

# dev
go run -tags goolm .

# prod
go build -tags goolm -o gogobee .
./gogobee

The -tags goolm flag selects the pure-Go crypto implementation. No C compiler or libolm needed.

First Run

1. Start the bot. It logs in, creates a device, bootstraps cross-signing, and self-verifies automatically.
2. That's it. E2EE works across restarts from here on out.

Passive Features

All of these run in the background without any commands:

• XP - 10 XP per message with 30s cooldown. Level-up announcements use Twinbee/Parodius themed messages.
• Stats - tracks words, chars, links, images, questions, emojis, and time-of-day patterns
• Streaks - consecutive days active, first poster of the day
• Reputation - detects "thanks", "ty", "thx", etc. with 24h cooldown per pair
• Achievements - 32 of them, checked silently on every message
• Markov chains - collects messages for !markov generation (10k cap per user)
• Keyword alerts - DMs you when someone says your watched keywords
• Presence - auto-clears away/afk when you send a message
• Room milestones - announces at 1k, 5k, 10k, 25k, 50k, 100k, 250k, 500k, 1M messages
• URL previews - OG tag extraction (feature-flagged, off by default)
• Reactions - logs all reactions for !emojiboard
• Space groups - rooms with sufficient member overlap are automatically grouped. Leaderboards, trivia scores, and other per-room features aggregate across the group. Recomputed hourly; persisted to SQLite. Uses strict clique-based grouping (every room must meet the threshold with every other room in the group).
• LLM classification - sentiment (10 categories), profanity, insults, WOTD usage (needs Ollama)
• Message buffer - last 50 messages per room held in memory for !vibe and !tldr. Not persisted to disk; resets on restart. Uptime reported when insufficient messages are buffered.

Sentiment Classification

Every message (subject to LLM_SAMPLE_RATE) is classified by Ollama into one of 10 sentiment categories. The bot reacts with an emoji when the confidence score is strong enough (|score| > 0.5). Per-user counts are tracked in the database and viewable via !sentiment.

Sentiment	Emoji	Score range	Example
Positive	👍	> 0.5	"This is awesome, great work!"
Excited	🔥	> 0.5	"OH MY GOD I can't wait for this!!"
Supportive	🤗	> 0.5	"You've got this, don't give up"
Grateful	💜	> 0.5	"Thank you so much for helping me"
Humorous	😂	> 0.5	"lmao that's the funniest thing I've seen all day"
Curious	🧐	> 0.5	"How does that work exactly?"
Neutral	—	—	"I'll be back in 10 minutes"
Sarcastic	🤨	< -0.5	"Oh sure, that'll definitely work"
Frustrated	😮‍💨	< -0.5	"I've been trying to fix this for three hours"
Negative	👎	< -0.5	"This is broken and nobody cares"

The LLM also returns a float score (-1.0 to 1.0) for each message. These scores are averaged per user to derive an overall mood shown in !sentiment output and fed into !howami roast profiles.

Why Go?

E2EE - This project went through three SDK iterations: matrix-bot-sdk (no E2EE support), matrix-js-sdk (E2EE via fake-indexeddb with an in-memory crypto store that wiped device keys on every restart), and finally mautrix-go which stores crypto state in SQLite with cross-signing bootstrap. The bot self-verifies its own device on startup.

Deployment - Pure Go, no CGo. go build -tags goolm gives you a static binary with zero system dependencies. The TypeScript version needed Node.js, npm, a C compiler for better-sqlite3, and libolm.

Scheduler - Replaced a hand-rolled 60s tick loop with robfig/cron. Standard cron expressions, less code, fewer bugs.

Plugins - Go interfaces + struct embedding instead of abstract classes. Same pattern, less boilerplate.

---

Database

Single SQLite file at $DATA_DIR/gogobee.db. Schema auto-creates on first run. WAL mode enabled.

40+ tables covering users, XP, stats, streaks, reputation, reminders, trivia, achievements, encrypted quotes (AES-256-GCM), backlog, keyword watches, scheduler config, birthdays, horoscopes, LLM classifications, stocks, concerts, anime, movies, countdowns, presence, markov corpus, reaction log, and various caches.

Backup

# safe to run while the bot is up (WAL mode)
sqlite3 data/gogobee.db ".backup data/gogobee-backup.db"

---

Troubleshooting

E2EE

E2EE should just work. The bot bootstraps cross-signing and self-verifies its device on first run.

1. After restarts, the bot reuses its saved device and crypto state. No manual steps needed.
2. If things are really broken, delete data/device.json and data/gogobee.db to start fresh.

Bot not responding in encrypted rooms

• Check that the bot joined the room (it auto-joins on invite)
• Look at logs for decryption errors

API commands not working

• Check that the relevant API key is set in .env
• Look at logs for error messages
• Most APIs have rate limits; the bot caches responses to stay within them

Build errors about libolm

# use the goolm tag:
go build -tags goolm -o gogobee .
