Patrick Astoul, founder of PinTool

Hi, I’m Patrick

I run a coffee blog.
I built this Pinterest tool for myself.
Then I shared it.

A founder letter — May 2026

Dear fellow blogger,

I run a small coffee blog called MasteringCoffee. Like you, I pour energy into posts that take a week to write, hit publish, and then watch the traffic graph stay stubbornly flat. Pinterest was supposed to be the shortcut — that fabled platform where good content still travels because algorithms haven’t entirely strangled organic reach.

For two years I tried to make Pinterest work the way the gurus said it would. Tailwind for scheduling. Pinclicks for tracking. Pin Generator for design. Each tool solved its little slice of the puzzle. Combined, they cost about a hundred euros a month and still didn’t answer the questions that actually kept me up at night:

  • Which keywords could my small account realistically rank for in 30 days?
  • Who were my real Pinterest competitors — not the big-name accounts I admired, but the ones Pinterest was actually grouping me with in the SERPs?
  • Which of my existing blog posts were under-pinned, and what should the next pin look like?

Every existing tool stopped at “here is the search volume,” which is the easy part. The hard part — what to do with that volume given my actual account size — was always left as an exercise to the reader.

So I built it. Not as a startup. Not as a venture. As the spreadsheet I wished existed, hooked up to the Pinterest Ads API, with some difficulty scoring on top. I used it for months on MasteringCoffee. Then I realised that if it helped me, it would probably help a few thousand other bloggers in the same boat. I cleaned it up, gave it a name, and put it online.

PinTool is, for now, a one-person product made by someone who uses it every day on his own blog. I priced it so a solo blogger can afford the full workflow — $12/month for the Starter plan, free for the first three searches a day. I publish the methodology openly on the blog — every difficulty signal, every SERP heuristic, no proprietary black box. And in the coming weeks I’m launching MasteringCoffee’s Pinterest account from scratch, publicly running PinTool against it, and publishing the numbers — impressions, clicks, ranking keywords — on this site as a running case study.

If you’re a blogger fighting for organic traffic in 2026, this is the tool I wished I had three years ago. The free tier is enough to validate the workflow on your niche before you spend a single euro.

And if it helps — or if it doesn’t, or if you have ideas for what should come next — I’d genuinely love to hear from you. The fastest way to reach me is patrick@pintool.io. Every email lands in my inbox, not a support queue.

Thank you for reading this far.
