Questions & Answers

As answered by people managing Tenoa.app and Project Euler.

What makes your product unique?

Tenoa.app's answer

Tenoa saves your library as plain files in a regular folder on your hard drive. Most visual bookmark managers lock your links and images inside a proprietary database. If you stop using Tenoa, your library survives intact. We built semantic search on top of those plain files so you can find things by meaning instead of remembering filenames.

Why should a person choose your product over its competitors?

Tenoa.app's answer

Tools like mymind or Eagle are great until they change their pricing or shut down. Tenoa is for people who want a visual library they actually control. You pay $49 once for the software and it runs locally. There is an optional $29 yearly charge for hosted sync, but if you skip it, everything on your machine keeps working forever.

How would you describe the primary audience of your product?

Tenoa.app's answer

I built this for people who have been burned by subscription tools holding their data hostage. The audience has a growing overlap with visual thinkers and designers who collect reference material. They want a visual way to browse their inspiration without algorithms or rented servers. They want their library to be genuinely theirs.

What's the story behind your product?

Tenoa.app's answer

I built it for myself first. I wanted a tool that worked like mymind where I could save anything without thinking about folders. I just refused to put my entire brain into another subscription service I didn't control. I built it solo and launched it in September 2026.

Which are the primary technologies used for building your product?

Tenoa.app's answer

The architecture is entirely local-first. Your library is a standard folder of markdown and media files on your disk. We use semantic embedding models to power the search so you can find concepts instead of exact text. The optional AI features run locally or through your own API key so your data never touches a server I control.
