# We build the software the profession was asking for.

RuleX researches with sources you can open, reads the entire case file, drafts the brief in Word, counts the deadline and monitors the case through to judgment. In twenty countries, with 5,000+ professionals working inside.

RuleX is legal AI software for Colombia, Latin America, Spain and the United States. besimpler S.A.S. builds it in Bogotá, and Alejandro Cárdenas, who uses it every day, leads it. It researches across more than 65,000 official sources, reads the case file, drafts the brief in Word, monitors court proceedings and signs documents, in 20 countries.

## Others answer questions. RuleX does the work.

A chat with a library beside it answers. A law office works: it reads the case file, counts the deadline, drafts the brief, reviews it, signs it and monitors the case through to judgment. That is ten distinct crafts, and they almost never happen in the same place.

**RuleX brings those crafts together in one place and connects them.** What you research arrives in the Redactor with its sources. What you draft is checked against the case file. What comes in from the court is filed in the matter with its deadline already counted. What you sign stays verifiable through a public link. Nothing gets copied from one tab to another, because everything lives in a single workspace.

That is the difference we were after when we started, and it still guides us: a lawyer who spends the day deciding, not moving files around.

## All the way through: Ten things RuleX does from start to finish.

Each one with its detail, because you can check a detail, while an adjective only asks for your trust.

- **Reads the entire case file.** Up to twenty files per message. When everything fits, RuleX reads every document in full; when the set is larger, it works through them one by one and flags any file left unreviewed.
- **Reads scanned documents.** OCR across the whole workflow — chat, case file, projects and the PDFs that court monitoring downloads: 400,000+ pages read, with stamps transcribed and blank pages detected.
- **Researches with sources you can open.** Seven specialized Colombian legal databases and more than 65,000 official sources. Every claim arrives with a link to the official document, and it opens straight from the answer.
- **Drafts the brief.** Asks questions before drafting, works with the case file alongside, cites specific passages and exports to Word with real headings, native lists and a “Page X of Y” footer.
- **Monitors proceedings.** Checks Colombia's Rama Judicial (the judiciary's official registry) every night and files the PDF of each court action in the case file. Official lookups in 6 countries, through Datajud (Brazil), JusCABA (Buenos Aires), the IUE (Uruguay), the SIREJ and the NUC.
- **Transcribes hearings.** Live, with each speaker identified and saved as it goes: a network drop never costs you the hearing. The transcript copies out by speaker and with citations.
- **Electronic signature.** One-time code by email, PDF sealing with a certificate and public verification by fingerprint comparison: 500+ documents signed.
- **Your own Apps and agents.** The office builds its own workflows without coding, tests them with a real run and shares them with its firm. Ten official Apps come ready to use.
- **Official public data.** SECOP (Colombian public procurement), RUES (business registry), Supersociedades, Superfinanciera and INVIMA, searchable from the chat, with source and date. 100,000+ procurement processes indexed.
- **Runs the practice.** Matters with tasks, dates and a log, plus clients, team and hours. 10,000+ matters managed; for firms, CRM, billing and reports.

## Count as of November 5, 2026

- **5,000 +** — professionals with their own accounts: solo practitioners, students, firms and in-house legal departments.
- **20 countries** — published in Spanish, Portuguese and English, each with its own court calendar.
- **1 million +** — pages of documents read and ready to query inside case files.
- **400,000 +** — pages of scanned documents read with OCR: folios, stamps and photographs.
- **8,000 +** — court proceedings under automatic monitoring, checked every night.
- **10 million words** — drafted in the Redactor: complaints, tutela petitions, appeals, contracts and legal opinions.

## 2026, month by month: what we kept adding.

- **January · The first chat and the tender finder.** The first legal AI conversation arrives, together with the Tenders section, with SECOP processes on a single board.
- **May · Firm management.** Client CRM, calendar and reports for law offices: the partner assigns, sees and bills.
- **June · Court monitoring and electronic signature.** The digital case file watches itself every night, and the document leaves RuleX signed, with public verification.
- **July · The Redactor.** The brief is drafted in a Word-style editor, with the case file and the sources alongside.
- **August · Seven legal databases of our own.** Research moves to seven specialized databases of Colombian statutes, case law and legal scholarship, and OCR reaches the entire document workflow.
- **September · Local pricing in every market and the official templates.** Local pricing reaches Latin America, Spain and Central America, each country with its own payment gateway. The 97 templates from the Ministry of Justice open in the Redactor.
- **October · Twenty countries and plans for every practice.** The United States joins and the count reaches twenty. The Student, Pro and Ultra plans are born, along with the Android app, live transcription with speakers and the PDF tools.
- **November · RuleX 3.0.** Growth, the case-file agent, pre-filing review, the hearing copilot, case law with its current status, Firm Memory and the tender analyst.

## Led by someone who uses it every day.

I'm Alejandro Cárdenas, founder of RuleX. I run it from Bogotá and I use it every day in my own legal work.

I started RuleX because legal work gets lost between tools: you research in one place, read the case file in another, draft in a third and monitor in a fourth, and the context drops between them. I wanted everything to happen in the same place, and every claim to arrive with its source open.

I spent months refining what shows least: reading scanned documents, the way a deadline is counted, the way a brief keeps every fact tied to its folio. It is the part that never shines in a demo and the part that decides whether a lawyer comes back tomorrow.

Today 5,000+ professionals work inside RuleX. We ship improvements every week, and many of them start with something a lawyer asked us for. If something is missing for you, write to me at equipo@rulex.org.

## One craft, twenty jurisdictions.

RuleX is published in 20 countries across Latin America, Spain and the United States, in Spanish, Portuguese and English. Each country comes with its own court calendar, its deadline calculators, its official sources, a Redactor loaded with the procedural templates of that jurisdiction and a published price.

Colombia is home: it is where the seven proprietary legal databases, the state's open data, the 97 Ministry of Justice templates and the 14 free tools live. Everything else was built from Colombia, and from there it reaches every country.

## Professional privilege is the starting point.

- **Your cases stay out of model training.** The AI providers RuleX works with operate under enterprise terms that exclude your account's content from training.
- **Your history is yours.** You can delete your conversations completely. When you close the account, everything you saved is deleted with it.
- **Files are served through signed links.** Each document is delivered through a short-lived link, and access is decided by authorized account and by team.
- **The content of a case file is data.** What a document says is never treated as an instruction to RuleX: it is read, cited and analyzed.
- **We audit and we fix.** We run security audits on our own code and fix the findings.
