Professional tools for songwriters, producers & publishers
Analyze, score and package your songs so they are ready to pitch — 5 free runs on every app, no API key required.
Every app gives you 5 free runs. Enter your email and go — no API key, no card, nothing to install. The 5 runs are per app, so you can try every tool in the lineup. After that, pick how you want to keep using it.
Per song: pay for a single analysis at checkout — runs on our API, no key to paste (see Lyric Analyzers below).
Buy outright: each app has a fixed price, shown on its card below and not open to offers. Owning an app unlocks unlimited use with your own provider key. Email to purchase; allow 24 hours for delivery.
During your 5 free runs you need no API key at all. Those runs use our provider account, on a model chosen by us, at no cost to you.
Tools marked 5 free runs then use your own provider account (OpenAI, Anthropic, Google, OpenRouter) once you own the app. Provider usage is billed by them — not a Pro Song Tools subscription.
Lyric analyzers: Preflight & Song Lane $5.00 per song; Golden Rule (audio) $10.00 per song — one full analysis on our hosted API, no key to paste. Or buy it outright for a full licence with bring-your-own-key — price on the card below.
Pro Song Tools does not resell API access. Pay-as-you-go on your provider account applies when you bring your own key.
Your email is used only to count free runs. It is not published, sold, or added to a mailing list. Keys you paste are held for your session only — never written to disk or to our config.
