Title: Bait-and-Switch: Breach of Contract and Missing Features
I strongly advise against purchasing Unmixr. The product delivered does not match the terms advertised on the AppSumo sales page. After purchasing the Lifetime Deal, I found that high-quality expressive voices were restricted behind a new monthly subscription, and advertised languages (including Luxembourgish) were completely missing from the platform.
Despite receiving a written promise directly from the founder to upgrade my account and provide the complete voice library across all languages, this commitment was not fulfilled.
Due to this ongoing breach of contract and false advertising, I have formally escalated the issue by filing official regulatory complaints against Unmixr and AppSumo with both the Federal Trade Commission (FTC) and the Texas Attorney General (Consumer Protection Division).
I highly recommend avoiding this product until they honor their original Lifetime Deal commitments.

Edited Sep 2, 2026Hi Juan,
Thank you for writing - and we're sorry this reached a review before it reached a resolution. That part is on us.
To be clear for anyone reading: nothing included in the AppSumo Lifetime Deal has been removed. Every voice, language and feature from the campaign is still active on your account today, and we have never revoked access to anything we promised.
The email you received was about our optional Pro Add-On. It adds Pro plan capability on top of your Lifetime Deal - your credits, voices and features stay exactly as they are. It's an upgrade sitting above what you own, not a gate placed in front of it.
We've also added a great many new voices since 2024, and the newer ones sit in separate categories in the Voice Library — which we suspect is why some looked missing. Filter by your language and by the categories in your plan and the full set from your deal is there.
I've written to you directly and I'm handling this personally. Send me the name of any voice or language you expected and can't find, and I'll take you straight to it.
- Shariful,
Founder, Unmixr
