FAQ
Questions about the toolkit
Is the tools hub replacing the thumbnail extractor?
No. GrabThumbs still starts with the YouTube thumbnail extractor for public video and Shorts thumbnails. The tools hub is meant to support adjacent workflow tasks around that core entry point.
Which tools are live right now?
The live workflow now includes the thumbnail extractor for public YouTube and Shorts thumbnails plus Competitor Thumbnail Board, Frame Hunter, Compare My Thumbnail, Thumbnail Test Flow, YouTube Title Checker, Thumbnail Text Checker, YouTube Description Formatter, and Shorts Caption Formatter.
Will the first creator tools require login?
No. The current plan is to keep the first versions browser-based and usable without login whenever possible.
Why keep a tools hub if the first eight tool pages are already live?
The hub keeps the public-thumbnail extractor, the live tools, and the best supporting guides in one place so users can move through the full workflow without hunting across the site.
