02 · PAPER
In the beginning, there was paper.
Millions of pages. Deadlines. Decisions. No one can read it all.
Then every letter became data.
03 · BRAIN
Brazilian law got a brain.
Letters became dots. Dots became connections. Ruling talks to ruling; law, to law.
04 · ORIGIN · SINCE 2008
Two brothers. Two languages.
One spoke Law. The other, code. In 2008, they became partners.
It was just a dream. No one imagined all of Brazil.
§Law. Anderson Macohin: deep knowledge of Brazilian social security law, since 2005.
{ }Code. André Macohin: programming back when AI was still rudimentary. He created Sistema Intranet.
Technology on one side, legal practice on the other. Each with the rules of its own profession. One shared project.

05 · THREE ERAS
2008 · SISTEMA INTRANET connects: those who look after the client with those who draft and file the case, the hub of thousands of legal professionals in Brazil. 2022 · ELZA A.I. answers. Now · ELZA SI works.
Specialised agents read, calculate and keep watch. A person makes the decision.
06 · BRAZIL
Born in Santa Catarina. Present across Brazil.
BRAZIL Technology and Sistema Intranet remain based in Balneário Camboriú, with André Macohin.
The hub that connects those who look after the client with those who draft and file the case, in Brazil’s 26 states and the Federal District. Colleagues recommend colleagues – and it is through this network, by referral, that cases arrive.
Brazil, now: --:-- in Brasília

07 · CRADLE
Balneário Camboriú.
The cradle of it all.
The city where this story began.
08 · ELZA SI
in the dark · opening her eyes
Hello. I’m ELZA SI.
Reads the whole case. Builds the case files. Handles the client’s first contact and prepares the case for the professional in charge. Talks by voice, inside the system.
09 · SI MEMORY · IN USE
15,079,684 case-law documents.
One question in Portuguese, and ELZA SI searches by meaning – also across more than 2 million publications in the Diário Oficial (Official Gazette).
One person would need about 628 years to read it all (5 min per document, 8 hours per working day).

Paper enters the system.
The sheet from the opening falls into a monitor showing the illustrative interface of Sistema Intranet.AI and becomes a sample document with fictitious data.
Four lenses on the same document.
Reading: she reads every line and checks it. Calculation: Elza reads, code calculates. Watch: she follows rulings and flags any change. Dossier: she builds the dossier; a person decides.
12 · PEOPLE
The people who write this story.
Behind the system, people.



Aline Macohin Coordinates the digital service lab with Elza.
And those who shared their technical knowledge at the latest event, alongside the team that works on the system.
13 · CULTURE
Dividir para Somar – divide to add.
The partner earns trust.
The litigator turns knowledge into legal action.
Macohin connects it all with technology.
Three independent forces, working as one.
Everyone contributes what they do best. People and systems, each doing their part.
14 · NETWORK
One artificial intelligence.
Hundreds of human minds.
552
faces. One network.
Real photos of people who are part of the network.
15 · YOUR NAME
Every story begins with a name.
Your name stays on your screen.
16 · THANK YOU
Thank you for believing when all of this seemed impossible.
In 2008, we had an idea, few resources and a conviction not everyone understood. None of this was built by just two brothers. Today, we dare to imagine a different future. To everyone who has been part of this journey: you helped write it.
If you’d like to be part of this group, Elza can talk to you for a few minutes.
