The case file that works with you.
LexIDE is the AI-powered legal workspace (an “IDE for law”) built for Mexican attorneys: every case lives in its own digital file, and an agent operates on top of it — reading your documents, researching a proprietary legal database of over 1.37 million records, and drafting your filings right inside the case file.
1.37M+ legal records in a proprietary database
~90s to analyze a complete case file
~$0.001 USD per deep research query
283+ platform functions (endpoints)
21 legal task templates (lawsuits, amparo filings, appeals, and research)
A complete working environment, not a chatbot
In LexIDE, every matter is a structured digital case file: the originals, their text versions, the theory of the case (facts, law, evidence, strategy), the filings, and the case's own body of precedent — all in one place. The AI agent doesn't answer in a vacuum: it knows that case file, knows which document you have open, executes actions, and saves what it drafts exactly where it belongs.
And there's a foundational decision that sets it apart: the application installs on the attorney's own computer, which means your clients' documents never leave it. The intelligence — the models and the legal database — is activated by subscription.
What it does for your firm
Seven capabilities that turn hours of desk work into minutes.
AGENTOne AI agent per case
Agentic chat that reads the files in the case and writes to it: it researches, drafts, and organizes without you copying and pasting a thing. Open several conversations per case, each running a different AI model.
For delegating whole tasks, not just asking questions
TEAMSpecialized sub-agents, running in parallel
The lead agent deploys a Researcher (finds and ranks relevant precedents), a Drafter (writes the filing and saves it to the case file), and a Reviewer (scores it 1 to 10 with suggestions). Several at once, while you keep working.
Like a firm inside your firm
ANALYSISFull case file analysis (the ⚡ Analyze button)
One agent per document, in parallel, extracts dates, people, arguments, and statutory articles; an orchestrator assembles the chronology, contradictions ranked by severity, chain of evidence, procedural risks, and strategy.
~90 seconds and ~$0.004 for a 14-document case file
PREPCase preparation (the 🔬 Prepare button)
Transcribes the audio, extracts text from documents and images, profiles the case (subject matter, jurisdiction, legal questions), runs dozens of auto-generated searches, and builds a case-specific law library the agent can consult instantly.
The case is prepared before you ask your first question
SEARCHHybrid search with an adversarial mode
Combines exact keyword search with concept search, re-ranks by legal relevance, and generates follow-up queries: articles cited within the precedents, plus heading variants that flag superseded criteria. In ERA 1 Adversarial mode, two AI attorneys argue opposing sides using only citations from the database, and an AI judge synthesizes the answer — including the other side's risks.
Deep research in ~33s · ~$0.001 USD per query
EVIDENCEStructured evidence ingestion
Processes audio (automatic transcription), images (OCR and vision), Word and PDF, and detects the legal structure: sections, normalized dates, and article references that feed the chronologies and the case analysis.
Evidence goes in once and works across the entire case file
DATAA proprietary, self-updating legal database
Over 1.37 million records: SCJN, JurisLex, FiscaLex, TFJA, TSJCDMX, and historical rulings, with semantic search across more than a million vectors. No third-party dependencies, no improvised internet lookups.
