I built a tiny SaaS in 2 days as a marketing channel for my main product

Last week I had an idea that wouldn’t let go.

What if I created a super small, super focused tool that solves one tiny piece of the bigger problem I’m working on with Fileo? Something people can use immediately. Something that delivers value in seconds. And something that quietly points them toward the full product.

So I built Clean_Name.
A free AI tool that renames PDFs based on their content.
Drop a file, get a clean, meaningful filename in seconds.

Took me 2 days from idea to launch.
And it is live now at cleanname.io.

It is intentionally tiny.
But it already demonstrates the core of what Fileo does on a much larger scale. It gives people a taste of the document intelligence behind Fileo without asking them to sign up or change workflows.

For me this is a fun experiment.
Can a micro product become an acquisition channel for a bigger SaaS?
Can you compress the essence of your main product into something that ships fast and spreads easily?

Let’s see where this goes. Happy to share the results as they come in.

Curious if anyone else here uses micro tools as part of their marketing strategy.
