personal discord bot running on my debian laptop. named after hayase yuuka. it started as a simple music bot and became a massive mess of features i sometimes use.

features

ai — uses deepseek v4 (flash/pro). text-only (no image/vision input), continuous memory summarization (so it doesn't forget context), per-channel personas (yuuka/rem), and native deepseek-reasoner thinking toggles. doesn't break character.
bridges — two-way telegram <-> discord message forwarding. twitter/x leaks via rss is implemented but currently disabled (Nitter RSS instances are dead).
media & music — lavalink + wavelink music playback (youtube search + http/icecast radio streams). also has ffmpeg media conversion slash commands (/togif, /caption, /reverse, /speed, /tomp4, /tomp3, /toopus).
sysinfo — live monitoring of my laptop's cpu, ram, temps (lm-sensors), top processes, and fastfetch.
utilities — live currency conversion (/currency), steam stat tracking (strinova player counts).
calendar — firestore-backed event booking via modal. autoconverts local times to UTC using a country list, feeds a web calendar frontend.
timestamp — /timestamp modal that generates Discord <t:unix:FORMAT> tags. accepts day numbers or day names ("Sunday"), handles month rollover, outputs all 7 Discord time formats.
timestamp (friends) — passive message listener: when a whitelisted user says "my time" in chat, the bot parses the surrounding text for time expressions, auto-converts to their timezone, and replies with timestamp tags. no commands needed.
junk — dice, coinflip, aura meter, rank, gifs, copypastas.

stack

python + discord.py
