Questions & Answers

As answered by people managing Konomic and StackMail.

What makes your product unique?

Konomic's answer

Konomic combines 30+ PDF tools and image tools (background removal, image compression, AI upscaling, passport photo preparation, OCR) in a single browser-based product. It is built privacy-first: files are encrypted in transit, deleted within 1 hour, never used for AI training, and processed on EU-based servers under GDPR. Basic tools are free without an account, and the paid plan covers everything at $4.99/month instead of separate subscriptions for a PDF editor, e-signature service, and image tools.

Why should a person choose your product over its competitors?

Konomic's answer

Pricing and privacy. Pro at $4.99/month includes the full toolset — editing, conversion, e-signatures, OCR, AI chat with PDFs — where competitors typically charge $9–25/month for narrower functionality. Files are auto-deleted within an hour and never shared or used for training, which matters for contracts and personal documents. The free tier is usable without a credit card and lets you test every tool, including AI features.

How would you describe the primary audience of your product?

Konomic's answer

Freelancers, consultants, and small businesses that handle documents daily — invoices, contracts, NDAs, proposals — and want one affordable tool instead of a stack of subscriptions. Also privacy-conscious users and EU-based companies that prefer GDPR-compliant, EU-hosted processing for their files.

What's the story behind your product?

Konomic's answer

Konomic is built by Konomic Digital SL, a software company from Tenerife, Spain. It started as a set of internal PDF utilities and grew into a public product after it became clear that most popular PDF services are either expensive, ad-heavy, or unclear about what happens to uploaded files. The goal is a complete document toolkit that is fast, affordable, and transparent about privacy.

Which are the primary technologies used for building your product?

Konomic's answer

Python with FastAPI on the backend, PostgreSQL, and Docker-based processing workers. OCR is powered by Tesseract 5 with support for 100+ languages. All processing runs on EU-based infrastructure.
