I run Toolfyra — a collection of 155 free online tools that run entirely in your browser. No upload, no signup, no watermark. This month I did something different: instead of guessing what to build, I pulled real search-volume data straight from the Bing Webmaster API and rebuilt my roadmap around it. Then I wrote 725 free step-by-step guides answering the exact questions people type into Google.
Here's the data, the tools, and the full page index.
The real Bing search volumes (Aug 2026, official API — not estimates)
These are actual monthly impressions from Bing's own API for keywords in my niche:
| Keyword | Monthly Bing impressions (US) |
|---|---|
| word counter | 34,782 |
| online calculator | 27,864 |
| paycheck calculator | 15,400 (broad match 36,515) |
| merge pdf | 13,328 |
| jpg to pdf | 13,260 |
| combine pdf | 12,328 |
| free pdf editor | 9,777 |
| gif maker | 8,079 |
| compress pdf | 7,644 |
| facebook video downloader | 2,477 |
Two things I learned immediately: my instinct-picks were mostly right, but the priority order was wrong — calculators and paycheck tools deserved to jump the queue. Data > gut feeling.
The tools (all browser-side, privacy-first)
Every tool runs locally in your browser via JavaScript/WASM — your files never touch a server:

🖼️ Image & media

725 free guides, built the same data-driven way
For every tool I mined autocomplete suggestions + question-style searches ("how to merge pdf files in iphone", "are free pdf editors safe"…) and wrote guides answering the exact phrasing people use — with the tool embedded on the page. Browse them here:

What's next
I'm extending the same real-data pipeline: more long-tail clusters, more calculators, and deeper guides for every tool. If you're building a tools site, my one-line takeaway: stop guessing — pull the search API data first, then build.
