A few months ago I got tired of watching creators including people I know personally make decisions about their YouTube channel based on guesswork. Is this niche even worth it? Is that channel actually monetized, or does it just look big? What tags should I even use?
So I built Toolbil a set of free youtube seo tools that answer those questions in seconds, without asking anyone to sign up first.
Here's the story behind it, and what I learned building it.
The problem I kept running into
I'm not a full-time YouTuber, but I know a lot of people who are and I kept hearing the same complaints over and over:
- "I don't know if this niche actually pays before I sink months into it"
- "I want to check if a channel is monetized before I collaborate with them"
- "Coming up with good tags takes forever and I'm never sure they're right"
- "Every tool that does this wants my email, my Google login, or $9.99 a month"
None of that felt necessary. Most of what creators need is public information it just isn't presented in a useful way anywhere.
What I built instead
Toolbil is a handful of small, focused tools, not one giant app trying to do everything:
Youtube Monetization Checker - paste any public channel and see its likely monetization status, estimated earnings, and CPM, based on public data.
Youtube tag generator - turn a video title into a real set of SEO tags instead of guessing
Youtube thumbnail downloader - grab any thumbnail at full resolution for research or reference
Video data extractor - see the exact metadata behind any video, useful for studying what's actually working in a niche
Youtube channel name generator and a sponsorship rate calculator, for people starting out or trying to figure out what to charge for a first brand deal
No login. No paywall. No "3 free uses, then pay." That was the whole point.
The part that mattered most: keeping it honest
The tempting thing with a tool like this is to make the numbers look impressive bigger estimates, more confident claims, flashier stats. I went the other way on purpose.
Every estimate on the site is labeled as an estimate. When the data genuinely can't tell you something (like exact watch-hours toward monetization, which YouTube doesn't expose publicly), the tool says so directly instead of making up a number that looks convincing. I'd rather a creator trust the 80% of the tool that's solid than lose that trust the first time they catch one number that was clearly guessed.
What building this actually taught me
A few things surprised me:
Simple beats clever, every time. Early versions tried to show too much at once charts, trends, comparisons. What actually got used was the plain, direct answer: yes/no, this number, that number.
People care more about trust than features. A tool that admits its limits gets used more than one that pretends to know everything.
"
No login required
" is still a real differentiator in 2026. It shouldn't be, but it is. People are visibly relieved when a tool just... works, without an account wall first.
Where it's at now
Toolbil is live and free at toolbil.com currently serving 4000 visitors a month, with new tools and blog guides added regularly.
If you're a creator, feel free to try it and tell me what's missing. If you're a developer who's built something similar, I'd genuinely like to hear how you approached the "free tool that stays honest" problem it's a harder balance than it sounds.
