Narrow focus
One or two products at a time. Each one earns its development budget by solving a real, specific problem for a real, specific person.
AskFolder is live
Launched October 2026
Calm software, thoughtfully built.
RPTX Software builds focused products that respect your attention, your data, and your time. Our first product, AskFolder, is live today at askfolder.com — it turns any folder into something you can actually ask, right in your browser: your files are never uploaded.

01 · Manifesto
We believe the best software gets out of your way — and only earns its place by doing a specific thing better than anything else.
02
Modern stack, shipped carefully
Plain JavaScript and WebAssembly, with AI models small enough to run on your own computer. Static pages on a global edge network, and no server holding your data. Current without chasing hype, and predictable where predictability matters.
03
Write the tests first
Every feature ships with a reproduction script. If we cannot break it on purpose, we haven't understood it well enough yet.
04
Respect your attention
No growth hacks. No notification spam. No "free trial" that quietly charges your card. We price honestly and cancel in two clicks.

Live now
AskFolder
Ask a folder of documents in plain words and get the passage, with its file and page. It all runs in your browser: nothing is uploaded.
Drop a folder into AskFolder and ask it in plain words. It shows you the passages that answer, with the file and page each one is on, and your files never leave your computer.
-
Search that understands
Finds passages by their meaning as well as their words, and forgives typos. A small AI model does it, inside your browser.
-
Every result cited
Each passage shows its file and page, with the words that matched highlighted. Open it to read it in place.
-
Nothing is uploaded
Your files are read on your own computer. The page's security policy forbids it from sending them anywhere, and anyone can check.
-
No sign-up
Open the page, drop in a folder, ask. No account, no install, no setup call.
-
Reads what you have
PDF, Word, text, Markdown, CSV and HTML. AskFolder Pro also reads scanned pages.
-
Works offline
Once it has loaded, AskFolder keeps working without a connection, on a train or behind a firewall.
Built for people who deal with a lot of documents.
Solo counsel & small legal teams
Find the paragraph in the contract that proves your point, cited back to the exact page. Every claim traceable.
Researchers & academics
Ask across a whole folder of PDFs at once. Find the methods, the quotes and the page each one is on.
Operations & vendor management
Ask your supplier archive about lead times and prices, and see the clause that says so.
Engineering onboarding
New hires ask the actual docs in plain English, not your Slack history.
03 · How we work
A small, deliberate loop.
-
01
Listen
Before a line of code is written, we map the exact problem with the people who have it. If we can't explain it in one paragraph, we don't understand it yet.
-
02
Prototype
A usable thing in a week, not a slide deck in a month. We get something in your hands fast so the feedback loop is real.
-
03
Harden
Tests, error handling, infrastructure chosen for longevity — the unglamorous majority of the work that makes software last.
-
04
Ship & tend
We stay with our products after they launch. Small, steady improvements beat splashy rewrites. A changelog, not a newsletter.
04 · About RPTX
Software, made carefully.
RPTX builds a very small number of software products, each designed to do one specific job exceptionally well. We prefer depth to breadth, durability to novelty, and the kind of reliability you only get from watching real users work with a tool over several years.
We ship carefully, iterate quietly, and write release notes that actually tell you what changed. When something breaks, we fix it and write down why.
05 · Frequently asked
Questions, answered plainly.
Are you taking on client work?
Rarely, and only for projects that align with what we're already doing. If you have an interesting problem involving documents, retrieval, or applied AI, drop us a line.
Where is RPTX based?
RPTX LLC is registered in Wyoming, United States. We invoice in USD and file US federal taxes transparently.
Who runs RPTX?
RPTX LLC is a founder-led company focused on retrieval, applied AI, and document-centric products, with twelve-plus years of production engineering experience behind it — more about RPTX. For KYC, vendor due-diligence, UBO verification, or any security questionnaire, see our Trust & security overview or email legal@rptxsoftware.com — we aim to respond within one business day.
What is your pricing model?
Pricing is published directly on askfolder.com. AskFolder is free for folders of up to 50 files; Pro is $9 a month, $79 a year, or $59 once. No "contact us for pricing" tiers, no hidden-inside-enterprise seats. If you can't find the price in thirty seconds, we consider that a bug. How payments are processed, which taxes apply, and how invoicing works are all documented on the product page.
Where can I find your legal terms and privacy policy?
All published at the bottom of every page: Privacy policy, Terms of service, why no DPA is needed, service providers, and Trust & security overview. AskFolder's own policy and terms are at askfolder.com/privacy and askfolder.com/terms.
Can we self-host your products?
In effect, you already do: AskFolder runs in your browser, and your documents never leave your computer, so data residency is wherever your computer is. If you need it on your own web server, write to legal@rptxsoftware.com and we'll tell you honestly what's possible.
Do you train AI models on my data?
No, and we couldn't: your documents and questions never reach us or any AI provider. AskFolder's model runs inside your browser. The few companies that see anything at all are on our service providers page.
How do I contact you?
Email is the fastest way: hello@rptxsoftware.com for general questions, legal@rptxsoftware.com for compliance, and billing@rptxsoftware.com for invoicing. We aim to reply within one business day, usually sooner.
