Free AI Video Summarizers: 5 Free Plans for YouTube, Bilibili & Podcasts (2026)

2026-10-13 · 5 min read

Here's the trap most "YouTube summarizer" roundups fall into: they assume every video you care about lives on YouTube. Yours probably don't. The course is on Bilibili. The interview is a podcast. The talk is on some platform you've barely heard of. A tool that only speaks YouTube covers maybe half your watch list.

This free AI video summarizer comparison looks past YouTube-only tools. Five options compared on publicly listed pricing and features — free tiers, source coverage, transcripts, and AI summaries. Our top pick is HotCopy: free to start with no credit card, and it handles YouTube, Bilibili, and podcast links in one place.

Free AI video summarizers: 5 options compared

Coverage matters as much as price — a free plan for a tool that can't open your links is worth nothing. Based on publicly listed features.

Coverage check: which tools handle non-YouTube sources?

HotCopy: YouTube + Bilibili + podcasts, all from pasted links. The broadest source coverage in this roundup.

BibiGPT (bibigpt.co): YouTube-focused summarizer; 3 free videos, then Plus $11.88/mo. Excellent within its lane, narrow outside it.

NoteGPT: URL-based, handles videos and PDFs with a limited free tier — decent breadth, but summaries without full transcripts.

ScreenApp: source-agnostic in theory — it records whatever is on your screen — but you're recording, not pasting a link, which is slow and clunky for a backlog.

Glasp: YouTube transcript sidebar via browser extension. YouTube-only in practice, desktop-only by design.

Tactiq: Zoom, Meet, and Teams meetings only. Not a video-link tool at all.

Free-tier limits to watch for (beyond the headline)

"Free" is never one number. When evaluating any free video summarizer, check these four limits — they're where the real constraints hide:

• Video count caps. The most visible limit (e.g., 3 videos total). Fine for evaluation, useless for a semester-long course.
• Minutes caps. Some tools limit total video minutes instead of video count. A 3-hour lecture eats a "10 videos free" tier faster than you'd expect — always convert to hours.
• Export paywalls. Getting a summary on screen is often free; taking the transcript out as a file is frequently the paid feature. If your workflow is "summarize → study notes," confirm export is included before you invest time.
• Source restrictions. A generous free tier for YouTube-only is worthless if half your content is on Bilibili or in podcast feeds. Coverage is a limit too — just an invisible one.

The pattern: the most honest free tiers limit quantity (videos, minutes) while keeping the full feature set. The least honest ones give you a crippled workflow and charge to unlock basics like export or timestamps. HotCopy's free tier follows the first model — full workflow, no credit card, with paid tiers ($6.9/mo Pro, $12.9/mo Max) only raising the caps.

Why choose HotCopy
