Signing · QES
Signing without the hassle
Signed up and signed your first document in 5 minutes. A QES accepted by government bodies and counterparties.

A contract in a minute.
Sign — right in the browser.
Describe it in words — AI drafts the contract, act or invoice. You sign with QES, the counterparty signs back.
Who eObig is for
One platform — for different tasks
Exchange with a counterparty
Two signatures, one original — without paper or couriers
You sign with QES in the browser and send the document to your counterparty. They sign back — and a legally valid original appears in both cabinets.
✓Signing without plugins — the QES is formed right in the browser; the key never leaves your device
✓The counterparty signs via a link — even if they don't have an eObig account yet
✓One original for two — a legally valid document and both signatures available to both parties
✓Real-time statuses — see when the document is delivered, opened and signed

The headline feature
AI that truly works with documents
Not a chatbot on the side: artificial intelligence writes, reads, analyzes, edits and fills documents — like a personal secretary, from draft to ready-to-sign.
✦A document from a description — AI drafts legally correct text, reading requisites from passport and vehicle-doc photos
✦A new document from existing ones — pick one or several of your documents — AI creates a new one based on them: an annex, an act, an updated version
✦Recognition from photos — photograph a paper document — the service turns it into a digital one, ready to sign and exchange
✦“Document essence” — parties, amounts, terms and contract pitfalls — before you sign
✦Edits in plain words — “change the price”, “add force majeure” — targeted edits, even live in the editor
✦Templates without routine — anonymization, auto-fill, and clients fill via a link with no sign-up
✦Create with AI
What do you need drafted?
E.g.: a car sale agreement between Ivanenko I.I. and Petrenko P.P., price UAH 250,000, Toyota Corolla 2019 (details — on the vehicle-doc photo)
Photos or PDFs (passport, vehicle doc, property docs) — up to 10

Pricing
No subscription — pay only for actions
Unusual for document flow: no tariff plans or monthly subscriptions. You top up a balance and spend it on specific actions. 100 tokens = UAH 1.
