Euphonia v0.2.0 — zero-setup insights

Choose a tag to compare

@Yuuzulight Yuuzulight released this 02 Aug 15:17

Every take now gets a written insight instantly, with no API key and no setup at all.

What changed

  • Insights are generated locally by a built-in rule-based writer that reuses the app's own metric zones (pitch, resonance, steadiness, vocal weight, phrasing) to pick what's working and the single clearest thing to try next — no network call, no account, nothing to configure.
  • A free Gemini API key is now a purely optional upgrade, not a setup step. Add one anytime from the ⚙️ Settings screen, and any take showing the built-in insight will offer a "✨ upgrade to an AI-written insight" button for a richer, more personalized version.
  • The first-launch API key prompt is gone — the app is fully usable the moment it's installed.

We also prototyped running a small local LLM (Qwen3, via HuggingFace) as a fully-offline replacement for Gemini, including a zone-aware prompt that explicitly tells the model which direction each metric is good/bad in. It wasn't reliable enough to trust for coaching advice, so we went with the deterministic built-in writer above instead — same zero-setup benefit, no risk of misreading your numbers.

Getting started

  1. Download Euphonia Setup 0.2.0.exe below.
  2. Run it — Windows SmartScreen will warn it's from an unrecognized publisher (it's unsigned; not a sign anything's broken). Click More info → Run anyway.
  3. Record a take. That's it — you'll get a written insight right away, no key required.
  4. (Optional) Add a free Gemini API key from the ⚙️ Settings screen any time for richer, AI-written insights. See docs/gemini-api-key.md for how to get one.

Requirements

  • Windows only for this release (see README for build-from-source options on other platforms)
