"Runs locally in your browser!

Unlike similar products, it’s free to use and doesn’t store your data. All processing is done in your browser, and your files are never uploaded anywhere. It runs well on computers and very slowly on smartphones; user beware."

I'm impressed by the fact that this was the choice made. I can only imagine it also helps keep the operational costs down, as well as liability for copyright and what not since they never become in possession of the content. However, it also means they "lose out" on a possible continuous source of training data which other less ethical evilCorp type companies would not pass up on

I'll be honest with you - I wouldn't even know what to do with user data if I collected it. I'm not great at training neural networks or understanding how to augment training with additional data.

Basically, the _only_ special thing about freemusicdemixer is that it runs client-side, because I'm better at writing C++ for a pre-trained network than I am at training new neural networks. However, it's a cool advantage so I'll keep promoting it as the distinguisher of my "product" (since I didn't create or train the underlying neural network, I just consider it a clever WASM frontend).

The operational costs are precisely $0 since it's a static website (aside from the domain registry).

Keep that mindset. Please. User data shouldn’t be your product. This is perfectly acceptable and thank you for doing this.

It is very nice to be able to compute this in our browsers without limits or registration. The results are not always perfect but already allows having good time testing remixes or doing karaoke with friends! Thanks for sharing your work.

I envisioned my site would be useful for quick and dirty prototyping - especially since the outputs are not licensed for commercial use.

Then, when one's project idea is validated, they could then used a paid stem separation service with higher quality and commercial licensing.

That's why I added some sentences on the website to solicit partnerships for targeted advertisements, to see if any pro demixing companies were interested.

That's an interesting idea. Scratch track stems while we're waiting for the approvals and delivery of final assets.
