Can You Use Free Text-to-Speech in a Monetized Video? I Checked the Actual Terms

Thanks, that's a good point, and I hadn't covered it, so I checked. ElevenLabs' help center says audio you generated during a paid subscription keeps its commercial license after you cancel. NaturalReader's Commercial FAQ says the same about files you made while subscribed. For Clipchamp I still can't find an official Microsoft page on it. With ForgePlug the question doesn't come up: Kokoro-82M is under Apache 2.0, which is perpetual and irrevocable. I'm adding this as a column to the table. Your habit of keeping a dated copy of the terms next to the audio is going into the takeaways, with credit to you.

Thanks for checking, and for the credit. Good to know ElevenLabs and NaturalReader both keep the licence on audio made while you were subscribed. Most people assume that and rarely confirm it. For Clipchamp, I'd say in the table that you couldn't find an official page rather than guess, since that's useful information on its own. The Apache 2.0 point is a real advantage for anyone building a back catalogue, because there's no subscription state to track at all.
