About TubeToolbelt

TubeToolbelt is a collection of 13 free utilities for YouTube creators and vloggers — the small everyday jobs around publishing a video: grabbing a thumbnail, sanity-checking a title, extracting a transcript, generating chapters, pricing a brand deal. Each tool does one job, does it in your browser, and gets out of your way.

The principles

• Free means free. No accounts, no watermarks, no paywalled export button. Creators already juggle enough subscriptions.
• Your files stay yours. Wherever possible the tools run entirely in your browser — uploaded thumbnails are previewed locally and pasted links are processed without storing anything about you.
• Honest numbers. The calculators show their working and their sources are published industry ranges. Where an estimate is just an estimate — RPM ranges, sponsorship benchmarks — the page says so instead of pretending to precision.
• No dark patterns. The only email box on the site is an optional new-tool announcement list. Nothing nags, nothing auto-subscribes.

How the tools work

Everything is built on public YouTube data and documented YouTube features: thumbnails come straight from YouTube's image servers, transcripts from a video's public caption tracks, subscribe links use YouTube's official sub_confirmation parameter, and the AI tools draft titles and chapters that you review before using. No tool automates engagement, inflates metrics, or does anything YouTube's terms frown on.
