Products
What the AI does in each one
Five sectors, one principle: the AI prepares, a person decides. Every address below is public.
A clinical co-pilot for psychologists: video sessions, clinical records and scheduling in one place.
Where the AI comes in
Transcribes the session and drafts a summary and a clinical note. The psychologist reviews, edits and signs — the AI never decides on its own. Risk signals in the content are flagged to the professional.
Market: Brazil · built for LGPD (Brazil's data protection law)
A platform to order and track registry, corporate and court certificates in Brazil.
Where the AI comes in
Reads uploaded documents with a vision model (AI-powered OCR) and extracts the fields each request needs. An AI-assisted risk analysis supports due-diligence review.
Market: Brazil
A workspace for ghostwriting agencies that write on behalf of several executives.
Where the AI comes in
Builds a “digital twin” of each executive's writing style from their own texts and drafts posts in that voice. Every draft goes through human review before it is published.
Market: Brazil
A co-pilot for people buying a used car in the United States — on the buyer's side.
Where the AI comes in
Decodes the VIN right in the browser and shows a fair-price band. The full report, under construction, cross-checks history, price and risks, with every finding citing its source.
Market: United States
An AI engineering school with an open curriculum: 63 modules across 5 tracks and 4 levels, published before the first lesson.
Where the AI comes in
Teaches how to build with AI — agents, deep learning, computer vision, natural language and MLOps — and states which production stage each module is in.
Market: Portuguese, English and Spanish
Addresses verified live on September 24, 2026.
Platform
What is shared
Anything two products need becomes a shared library before it becomes one product's code. That is what lets a small company keep five products on the same security standard.
- ai-engine
- Shared AI engine: chat, embeddings and RAG (document retrieval with pgvector) across models from more than one provider.
- prompt-guard
- Layered defense against prompt injection: normalizes input, detects attack patterns and filters model output.
- crisis-detection
- Three-level screening for risk signals in clinical text. When in doubt it flags — the professional decides.
- auth · billing · rate-limit
- Per-product sign-in, billing and request rate limiting, written once and reused.
- i18n · ui
- Shared languages and interface components — including the language switcher on this site.
How the engineering is done
AI agents from more than one provider
Development is carried out by AI agents (Claude and Gemini) organized in a hierarchy: an orchestrator splits the work, worker agents implement it, and a reviewer running a different model approves it.
A council of models for decisions
Architecture and product decisions go through a round in which different models give their opinion in parallel, and the record is kept next to the code.
Automatic security gates
Every change goes through automatic checks that block dangerous patterns — secrets with default values, access to another customer's data, unsanitized HTML — before it reaches production.
