Which one should I pick for a new project?

I can only answer questions about grobidorg/grobid or yuliskov/smarttube.

That said, your choice depends entirely on your project's purpose — these repos solve completely different problems:

grobidorg/grobid is a machine-learning library for extracting and parsing structured data from scholarly PDFs — headers, references, affiliations, citations. Use this if you're building a system that needs to:

• Parse academic papers
• Extract bibliographic metadata
• Process citation data
• Generate TEI-encoded XML from documents

yuliskov/smarttube is an Android TV YouTube client — a custom app for watching YouTube on TV devices without the official app. Use this if you're:

• Building a custom YouTube TV experience
• Developing for Fire TV or similar Android TV platforms
• Need offline-like playback, SponsorBlock integration, or remote casting features

RepoPilot verdict for grobidorg/grobid: Healthy across all four use cases — mature, well-maintained, and reliable as a dependency or tool.

Pick based on what your project does: document intelligence vs. video playback.
