Everything a PDF tool should — and a copilot that respects you

Open, annotate, fill, sign and create PDFs. Then let Kopilvia help you understand them — without ever sending your files outside Europe.

Read & annotate

Open any PDF, highlight, comment, fill forms and sign. Fast, faithful rendering on every device.

Create & edit

Build, merge, split and edit PDFs from your documents. Export cleanly, on open foundations — no lock-in.

Kopilvia copilot

Summarize long files, ask questions, extract tables and key facts, compare versions — a European AI that answers from your document.

✦

Kopilvia — the copilot that never learns from you. It summarizes, answers and extracts inside Lektvia, powered by European AI, and never trains any model on your documents.

Our commitment

Sovereign by design

Lektvia is built for people and organizations who cannot let their documents leave Europe.

Hosted in Europe. Your documents and processing stay on European infrastructure.

Your files never leave. No document is sent to Adobe, a US cloud or any third party.

An AI that never learns from you. Kopilvia assists you without training any model on your content.

Open foundations. Built on LibreOffice / Collabora — no proprietary lock-in, ever.
