Welto vs NotebookLM
NotebookLM reasons across documents you can already read. Welto makes video you can't understand readable, watchable and studyable in your language.
You have a pile of PDFs, notes and spreadsheets in a language you read, and you want one AI that reasons across all of them with citations. That's NotebookLM's home turf, and it's genuinely good there.
Your source is a video or podcast, in a language you don't fully follow, and you want it translated, subtitled and turned into notes you can study. That's what Welto is built for.

Where NotebookLM is better
One thing, and it matters: NotebookLM reasons across a whole library of sources at once, with citations back to the passage, while Welto works on one video at a time. Its Audio Overviews are genuinely good too, but Welto now has its own two-host podcast, in your language, with the script on screen. What Welto does that it doesn't: put your language onto the video itself, as subtitles, a bilingual reader and files you can keep.
Common questions
NotebookLM helps you reason across documents you can already read; Welto helps you understand video you can't, by translating and subtitling it into your language.
No, and it isn't trying to. If your problem is a pile of documents you understand, use NotebookLM. If your problem is a video in a language you don't speak, that's Welto. Plenty of people use both.
