Our tools, inside your software
Clausa, Virgo and Paginta — the document tools we run for our clients — available for your own software to use, or for an AI assistant to use on its own.
Service notice
Good to know before you build on it
- Requests are rate-limited by IPEach IP address can send a limited number of requests. Past the limit the API answers 429 Too Many Requests; when a Retry-After header is present, wait that many seconds before sending again.WhyLimits keep the service fair and responsive for everyone, and help protect it from misuse.
- Slower at peak timesDocuments share one processing queue, so at busy times a request can take noticeably longer than usual — large files most of all. When the queue is full the API answers 503; retry a little later.WhyAnalysing documents takes real computing work, so when many requests arrive at once they wait their turn. We expand capacity as demand grows.
- Downtime can happenThe platform is in early access and has no uptime guarantee yet. A service may be briefly unavailable for maintenance or an unexpected outage, so retry with backoff and keep it off paths that cannot wait.WhyThe platform is updated and improved regularly. Updates, and the occasional unexpected issue, can cause short interruptions.
Two ways in
Use it from your software, or let an AI assistant use it
- REST APIFor developers: your software sends a request over the web and gets a predictable answer back — the same way every time, whether you ask once or a million times.
- MCP serverFor AI assistants: the same service offered through MCP, so an assistant like Claude can find it, understand what it does and use it on its own — no custom code needed.
What it does
Tools that do one job well
Each one is already in real use somewhere — in one of our products, or inside a client's system.
Clausa
Vietnamese administrative & legal text
Who issued it, who signed it, what it replaces — read from Vietnamese official documents
Reads the text of decisions, official letters, decrees and circulars — straight from your OCR, or typed without accents — and pulls out who issued each one, its number, date, who signed it and which laws it relies on. It also shows how documents connect: which one cites, replaces or cancels another. It is small enough to run on your own servers, so your documents never leave your organisation.
- Pull out issuer, document number, date, signer and their position
- Show how documents connect: issued by, based on, replaces, cancels
- Read text typed without accents or in all capitals
- Clean up OCR text: drops signature stamps and logos, fixes QD to QĐ
- A confidence rating on every detail, so unsure ones go to a person to check
- REST API
- MCP server
- AI agent
- On-premise
Virgo
Vietnamese contract review
Find the contract clauses worth a second read
Send a Vietnamese contract — a PDF whose text can be selected, a Word file, a text file, or just paste the text — and get back the clauses to read carefully, where they are on the page, and what to ask the other side. Each clause is checked against nine common risks, penalties and interest are checked against legal limits, and blanks left unfilled are flagged. Results are suggestions — they do not replace a lawyer or make the decision for you.
- Split a contract into clauses and check each against nine risk groups
- Flag penalties over 8% and interest over 20% a year
- Detect blanks left unfilled
- Show where each clause is on the page, so it can be highlighted
- Suggest what to ask, what to watch, and a clause to add
- REST API
- MCP server
- AI agent
- On-premise
Paginta
PDF to Word · EN / VI / FR
Your PDF, rebuilt in Word — tables and all
Turns long reports, multi-column pages and financial statements into a Word file where every table is a real table you can click into and edit. Works best in English, Vietnamese and French, accents intact. It never rewrites or summarises — what was on the page is what lands in the document — and every conversion comes with a check report: how many pages and tables, which garbled text was fixed, and how many table cells match the original.
- Turn a PDF into an editable Word file — scanned pages too, on the Pro plan
- Rebuild tables cell by cell, merged cells included
- Keep two- and three-column layouts in reading order
- Carry charts, logos and photographs over at full quality
- Fix garbled text and report how many table cells match the original
- REST API
- MCP server
- AI agent

On-premise
Keep your documents in-house
Virgo and Paginta can also run just for your organisation, in one of two ways.
- Dedicated hostingWe run a separate server for each client. Your documents never share a machine with anyone else's.
- Rented applianceWe place our server inside your office network. Your documents are processed on site and never leave your premises.

We are opening the platform up gradually, and we would rather start from a real project than a signup form. Tell us what you are building and we will set you up.
