About BibiGPT

BibiGPT is your AI assistant for understanding audio and video. It summarizes Bilibili, YouTube, podcasts, and local files, produces mind maps, transcript timelines, and long-form rewrites, and supports multiple large language models with personalized output styles.

Unlike typical summary tools, BibiGPT can reason about on-screen visuals, publish image-rich newsletter-style articles, and keeps you in "watch faster, search smarter, reuse better" mode alongside Notion, Obsidian, and other knowledge bases.

01

Watch faster

Skim long-form media without losing access to the full context.

02

Search smarter

Transcripts and highlights stay fully searchable with jump-back timestamps.

03

Use better

Chat with any media, draft target articles, and reuse insights without manual formatting.
