The company, and the person behind it.
Peter Acs
Founder · Software engineerPeter is a software engineer with twelve-plus years of production engineering experience across backend systems, data pipelines, and applied machine learning. His work has ranged from consumer APIs handling tens of millions of requests per day to enterprise data platforms measured in uptime, migrations, and late-night pages.
He founded RPTX in 2026 to focus on building a very small number of software products, very well, for a very long time — with the specific goal of shipping durable tools to people who actually use them, rather than optimizing for growth metrics or acquisition narratives.
AskFolder is the first product. It turns any folder on your computer into something you can ask, every result cited to its file and page, and it runs entirely in your browser: your files are never uploaded.
The studio
RPTX LLC is a limited liability company registered in the State of Wyoming, United States, publishing software products under the brand name “RPTX Software”. The company was formed in 2026 and is founder-owned.
We invoice in US dollars and file US federal taxes transparently. The full list of vendors that handle payment or personal data on our behalf lives on our service providers page; billing specifics for each product are documented on its own site.
Our engineering philosophy is summarised in the manifesto: narrow focus, modern stack shipped carefully, reproducible tests, and respect for the attention of the people who use our products.

Everything a compliance team typically needs is published or available on request:
- Trust & security overview — how AskFolder works, and why we hold no customer data.
- Data processing — why no DPA is needed.
- Service providers — every third party we use and what they see.
- Privacy policy and Terms of service.
- security.txt — vulnerability disclosure contact and policy (RFC 9116).
