Frequently Asked Questions

What is the best free alternative to Eightify?

Glasp (YouTube Summary with ChatGPT & Claude) offers the most generous free tier — unlimited desktop summaries with no payment required. PeekaTube offers 3 free trials before requiring a $5.99/month subscription, which is worth it if you need YouTube comment analysis and multilingual output that Glasp does not include.

Which Eightify alternative is best for students and researchers?

Google NotebookLM is the strongest pick for students working with multi-source research projects (lectures + PDFs + papers). For pure YouTube workflows — lecture summaries, in-context comment analysis, exportable notes — PeekaTube is faster and more focused. Many users use both: PeekaTube for quick triage on YouTube, NotebookLM for deep cross-source research.

Why would I switch from Eightify to PeekaTube?

Three reasons users typically switch: (1) PeekaTube includes YouTube comment analysis that Eightify either lacks or treats as a separate feature, (2) native output in 10+ languages without prompt-engineering, and (3) one-click export for note-taking and research workflows. If those three matter to you, PeekaTube is the upgrade. If not, sticking with Eightify is fine.
