Kortex-Notebooklm alternatives
2 open-source projects that already do this job. Free to use - not free to run, which is what the numbers on the right are for.

What you give up either way
- Polished multi-language UI, weekly feature cadence, and UX polish
- Pre-built integrations (Google Docs sync, many third-party imports) and team/SSO admin tooling
- Automation pipeline UI with pre-built rules and hosted reliability/uptime SLAs
- Podcast feed management and hosted audio bandwidth at scale
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Kortex-Notebooklm, and it does not prove anyone has run it for a month. How we decide.
