Finding a song meant leaving the chat. DTexter finds it from a name or a few seconds of audio, sends the track and fetches the lyrics, all inside Telegram.

Never leave the chat
- Find a song from a name or a few seconds of audio.
- Send the track and its lyrics as messages.
- Answer a repeated request at once, from the cache.
The small things that made it work
- 01A name in, seven results out
Type a song and pick from seven results; the arrow brings the next seven.
- 02The track, as a message
Tap a result and the song arrives in the chat, from the cache when it was sent before.
- 03A voice note becomes a song
A few seconds of audio are enough to find it (2022).
- 04The words, one tap away
Lyrics come back as a message under the song (2022).

How a request travels
The 2022 bot was Python with ACRCloud, spotDL and a Postgres cache; the 2025 rewrite is a long-polling Go program on the Spotify Web API.

Who worked on what
A good bot hides the pipeline and keeps the conversation moving.
