Disclosure: I'm the developer. Below is a draft entry following the toolkit
structure, feel free to use, edit, or discard any of it.

## Description
A search engine for deleted, removed and unavailable YouTube videos, built on
web archives (Wayback Machine, Common Crawl, the 2019 YouTube metadata dump).
It indexes 1.5B+ video records since 2005. Researchers can list all known
videos of a channel (including deleted ones, via URL, @handle or legacy
/user/ and /c/ formats), run full-text search across titles, descriptions and
subtitle transcripts, and recover metadata of deleted videos: original title,
description, upload date, view counts and thumbnails. Subtitles can be
downloaded as SRT (240+ languages), including for deleted videos when a
caption track was archived. Each result links to the underlying archive
snapshots, which can be cited as evidence.

## Cost
Free (core search and single downloads, no registration required). A free
account raises limits; paid plans add bulk export, API and MCP access.

## Level of difficulty
Beginner. Works in the browser: paste a video URL, channel link or keywords.

## Requirements
None for basic use. Free account for higher limits.

## Limitations
- Coverage depends on whether a video was archived before deletion; obscure
or short-lived videos may have no records.
- Usually recovers metadata, thumbnails and subtitles rather than the
playable video file (archived files are surfaced when they exist).
- Recently deleted videos may not appear in the index immediately.
- AI-generated transcripts may contain recognition errors.

## Ethical Considerations
- Some videos are deleted for legitimate reasons (privacy, consent, safety
of persons shown); consider potential harm before republishing recovered
content, and minimise exposure of private individuals.
- Archived metadata can reflect an intermediate state of a video (e.g. an
older title); verify against the linked archive snapshots before citing.
