Not a cloud master

Why it is not $15/mo.

LANDR-style services charge rent to upload an unreleased master. CoProducer is a local instrument. You buy the engine once.

Pro is a lifetime license at $29. There is no Starter subscription and no per-track cloud fee on this page — those would fight the rest of the product. Studio is a conversation when you need extra seats, not a third monthly SKU.

Questions

Before you pay.

Is Pro monthly?

No. $29 once. The old three-tier monthly mock on this URL was a placeholder and did not match the product.

Do I need the web API?

Only to try Analyze in the browser. The desktop app is the real engine: same scoring, plus repair that writes a file.

Will repair restore clipped transients?

No. The report will say so. Limiting can zero the clip count; it cannot un-flatten a peak. Go back to the session when you still can.

Pricing FAQ

Is there a monthly subscription?
No. Pro is $29 one-time.
Does the website download a repaired master?
No. Web analyze shows projected post-repair stats. Desktop CoProducer writes the WAV.
Is this cloud mastering?
No. CoProducer is local-first analysis and conservative technical repair — not an upload-and-master service.
