SOFTWARE YOU BUY ONCE AND RUN ON YOUR PC
NO SUBSCRIPTIONS. ZERO CLOUD UPLOADS. PERMANENT DESKTOP APPS.
We build focused Windows software for jobs that are still slow, expensive, or trapped behind recurring rental fees. Pay once, keep your license forever, and run every task entirely on your own hardware. Your confidential documents never leave your machine.
PAY ONCE, KEEP FOREVER
One single price, yours to keep forever. No monthly subscription, no renewal traps, and no premium features locked behind enterprise paywalls.
100% LOCAL PRIVACY
Your confidential files are processed entirely on your local CPU and drive. Your documents are never uploaded and there is no telemetry. The app goes online only when you press Activate or Check for updates.
NATIVE SPEED & AUTOMATION
Engineered specifically for Windows 10 & 11 (64-bit). Fix whole folders of documents in one batch; every file is validated with veraPDF 1.30.2 and logged.
COMPANY ADVANTAGES
PERMANENT LICENSE
Buy once on Gumroad, receive your key immediately, and keep running the version you bought with zero renewal fees.
WORKS OFFLINE
No internet is needed to process documents, run OCR, draft alt text or generate audit reports. A PC without internet can activate from another device.
VERIFIED STANDARDS
Every result is checked with veraPDF 1.30.2 against PDF/UA-1 (ISO 14289-1), the PDF part of the standards behind the European Accessibility Act. Machine-verified, not a certification.
AUDIT-READY REPORTS
Exports an Accessibility Conformance Report in the VPAT® 2.5 layout, a draft EU accessibility statement and CSV logs.
BUILT-IN LOCAL AI
A small vision model ships inside the app and drafts alt text for every picture on your PC. No API keys, nothing to install; every draft stays marked until you accept it.
DIRECT HUMAN SUPPORT
Direct communication with the software founder and creator. No automated telephone trees, no generic support chatbots.
OUR CASES
TagSmith-PDF

VRAM Fit Calculator
Calculate GPU memory requirements for quantized LLMs and vision models before downloading weights.
Free Model Catalog
Free hosted models that were actually called with a real request on the last check — a dated record, not a listicle.
