The service
One memory. Three layers.
Start with your personal brain. Add agents that answer from it. Scale it to the whole company.
01 · For you
Your professional memory, organized once and for all.
We turn your notes, documents, meetings and decisions into a living, connected library — a map of what you know. Ask in plain language and get an answer with the source right beside it. And the files are yours: open, readable, portable.
- — Everything you know, in one place
- — Every answer shows where it came from
- — Your files, yours forever — no lock-in
02 · With you all day
Ask from wherever you are.
Assistants always on in the tools you already use — WhatsApp and Telegram — permanently connected to your organized, maintained memory. No new app. No extra tab. Just send a message and get the answer.
- — WhatsApp and Telegram, where you already talk
- — Answers grounded in what's yours, not the internet
- — Memory cared for and kept up to date by Arvor
03 · For your company
The institutional memory that never walks out the door.
We organize the knowledge of the whole company — contracts, projects, decision history, the know-how that today only lives in people's heads — with smart search built to measure, access control and human review. The foundation comes from two decades organizing information at scale for Brazil's largest players.
- — Knowledge stays with the company, not just the people
- — Control over who sees what, with human review
- — Built to measure for your business
Who it's for
Every job that runs on knowing.
If your day depends on what you and your team know — and on finding it at the right moment — Brain Maker was built for you.
Law firms
Briefs, contracts, arguments and internal case law become a memory you can query — the new associate asks the archive, not the partner.
Doctors & clinics
Protocols, clinical guidelines, literature and case history organized for instant lookup — with the source, between one appointment and the next.
Independent professionals
Consultants, accountants, architects, engineers: every project delivered becomes a body of work that answers the next one.
Candidates & public office
Positions, speeches, promises, district data and voting history — instant consistency for anyone speaking in public every day.
Business owners & executives
“Where did we decide that?” stops being a question for the team and becomes a question for your memory — answered in seconds.
Teams & companies
Onboarding that answers itself, context that survives people leaving, decisions that don't get lost in threads.
Agencies & studios
Briefs, campaign learnings and every client's history accessible to the whole team — Friday's pitch draws on ten years of what the agency has learned.
Researchers & creators
Years of reading, interviews and drafts, all connected — your next idea finds everything you've already thought about it.
The engine
Memento
Local-first memory, built by Arvor.
Memento keeps the graph organized, captures what matters and gives agents a reliable map of your knowledge. Every answer arrives with its source right beside it.
Our own tool, our own methodology. No black box: your files stay readable by you — and by any tool you choose tomorrow.
Why Arvor
Two decades organizing knowledge at scale.
Before Arvor, founder Leonardo Dias built enterprise search for Brazil's largest players — e-commerce, banking, telecom, energy and media.
As a co-founder of Semantix, he helped take the company to NASDAQ in 2022 — with around 300 clients, ~10 petabytes of data under management and over 6 billion transactions per month, according to figures published by the company itself.
Brain Maker is that experience, applied to your knowledge.

How it works
Four steps. One brain.
01
Diagnostic
We map where your knowledge lives today: files, emails, chats, systems — and heads.
02
Collection
We bring it all in: documents, meetings, decisions, history. What matters comes in.
03
Organization
We connect and structure it: what was chaos becomes a map of your knowledge, with everything in its place.
04
Connected assistants
We connect the assistants to your brain — on WhatsApp and Telegram, ready to answer with sources.
FAQ
Straight answers.
What exactly do I get?
Your knowledge library, organized and connected, in open files that are yours forever; assistants connected to it on WhatsApp or Telegram; and training to keep it all alive in your routine. For the tech-curious: it's compatible with tools like Obsidian, and the memory runs on Memento, Arvor's own engine.
Is my data safe?
Your brain is built in open files that stay under your control, with backup and governance defined in the project. When confidentiality demands it, we work local-first. Sensitive actions go through human review.
Does it work for large companies?
Yes. We organize knowledge at large scale, with smart search built to measure, access control and tools specific to your project. The experience comes from two decades organizing information for Brazil's largest players — e-commerce, banking, telecom, energy and media.
How much does it cost?
