On the echo, a few questions so I can pin it down:
1. Which version are you on (Parrot menu > About Parrot)? 0.24.0 fixed a bug where the mic track and the system audio track could start a few seconds apart, which sounds exactly like two copies of the same voice. If you're on something older, updating fixes new recordings (old ones stay as they are, sorry).
2. Were you on headphones or speakers? On speakers the mic also picks up the other person. The echo canceller removes most of it but not all, so you can get a faint second copy a split second behind.
3. Roughly how far apart are the two copies? A short slapback points at mic bleed, a clear repeat of whole words points at timing or routing.
If you have a minute, one short test call with SoundSource and the other transcriber quit would tell us a lot. Both hook into system audio, and I want to rule out Parrot recording the call twice.
Happy to dig in on GitHub if that's easier: https://github.com/turantekin/Parrot/issues
On Markdown: that already exists, it's just tucked away in settings. Settings > Connections, pick a folder (your Obsidian vault works) and switch on automatic saving. Every finished meeting lands there as a note with front matter, summary, next steps as checkboxes and the full transcript. Saving again updates the same note instead of making a copy.
And since you mentioned agents: Parrot can also connect straight to Claude, Cursor or Codex (Settings > Claude & AI Apps), so they can search your meetings directly.
