Why Cerveau.ai?

Grow your output,
not your organisational overhead

Between idea and execution, there's a gap — and it widens every time you switch context, add a project, or take on something new. Cerveau.ai connects your thinking automatically, so the information you need to act is always one step away.

One place for everything

One product for all things people

Ideas, projects, research, and decisions in one place, linked automatically. No more hunting for the thing you definitely wrote down.

Fits your existing stack

Works where your team already does

Capture from Slack, email, or voice. Query over MCP. Export to Notion or Linear. Cerveau.ai adds the connective layer without replacing what works.

Built on specific principles

Opinionated, not configurable

Cerveau.ai follows a specific set of principles for how knowledge should be captured, linked, and surfaced. You get the system, not a blank canvas.

Second brain

From scattered context
to shipped decisions

Capture, connection, surfacing, and brief generation run automatically. Your brain never has to hold everything at once.

Frictionless capture

Voice notes, quick text, forwarded emails, and clips land in one inbox. Capture mid-thought without stopping to file.

Automatic linking

Cerveau.ai finds the connections between your notes, projects, and decisions — without you maintaining a taxonomy or remembering to tag.

Context surfacing

Open a project and relevant notes, past decisions, and related ideas surface automatically. The right context, without a search.

Focus mode

One task, one context, everything else out of view. Focus mode surfaces only what's relevant to the work in front of you.

Execution briefs

Cerveau.ai compresses a project's full context into a single actionable brief. Pick up cold after three weeks and know exactly where to start.

Weekly review

What you captured, what shipped, and what needs to move forward — every week, without a manual process.

How it works

Set it up once.
Run forever.

Connect your capture channels, define your active projects, and Cerveau.ai handles the organisation, linking, and surfacing automatically from there.

Capture anything, anywhere

Every idea, voice memo, and forwarded email lands in one place without interrupting your flow. Cerveau.ai processes and organises it in the background.

Connect everything automatically

New captures link to existing notes, active projects, and relevant past decisions — building a graph of your thinking without any manual filing.

Surface what matters now

When you sit down to work, the right context finds you. Relevant notes, open decisions, and suggested next actions — without searching.

Build an execution brief for the Q3 product launch
Execution plan
Collect scattered captures
14 notes, 3 voice memos, 2 forwarded emails
Link to existing context
Connected to 6 related notes and past decisions
Identify conflicts and gaps
2 open decisions flagged, 1 missing owner
Generate execution brief
Context, decisions, and next 3 actions
REASONING
The Q3 product launch has 3 open decisions — pricing model, launch sequence, and outreach strategy. The positioning note from March conflicts with the brief from May. Recommend resolving pricing before briefing writers.

Pricing model — 2 contradicting notes found
Execution

Continuous momentum,
not quarterly restarts

Cerveau.ai maintains the execution state of every active project — so you can pick up exactly where you left off, even after a week away.

Automate cadence and refresh

Maps run on your schedule. Cerveau.ai surfaces new gaps, flags regressions, and generates updated briefs automatically each cycle.

Data from your actual sources

Cerveau.ai pulls signals from tools your team already uses — so briefs reflect what happened, not what people remembered.

Agentic brief generation

Agents cluster context, flag contradictions, and surface the specific actions that will move the project forward this week.

Built for

Different roles. Same platform.

Lean growth for
Founders and CEOs
Turn the chaos of building into a system that compounds. Every idea captured, every decision logged, every project movable.
Shipped work for
Creative professionals
The gap between having the idea and sending the thing. Cerveau.ai closes it — automatically, without a new process to maintain.
Calm execution for
Operators
Build the system that runs the business. Cerveau.ai handles the context management so you can handle the decisions.
Security

Opinionated by design,
not configurable by default

Most productivity tools give you a blank canvas and let you build your own system. Cerveau.ai follows a specific set of principles for how knowledge should move from capture to execution — built into the architecture, not the settings menu.

Capture first Organise later, automatically
Context always Nothing lives in isolation
Execution-oriented Every note leads somewhere
No maintenance The system runs itself
Integrations

Works where your thinking
already happens

Capture agent

A frictionless inbox in Slack, email, and mobile. Send a thought mid-meeting, forward an article, drop a voice note — Cerveau.ai organises it without asking you to.

MCP interface

Connect Cerveau.ai to Claude web, Claude Code, or any MCP-compatible host. Your entire second brain is queryable from the AI tools you already use.

Platform integrations

Notion, Linear, Google Docs, and calendar sync. Cerveau.ai adds the connective tissue to your existing stack without replacing the tools your team uses.

Frequently asked questions

An AI second brain is a system that captures your knowledge, links ideas that belong together, and surfaces the right context when you need to act — so you spend less time searching and reconstructing, and more time executing. Cerveau.ai is AI-native. Where legacy note-taking tools were built to store information, Cerveau.ai is built to close the gap between knowing and doing.
Notion and Obsidian are powerful blank canvases — but they require you to design and maintain the system. Cerveau.ai is opinionated. There's no taxonomy to manage, no templates to maintain, and no filing step between a thought and an organised second brain. You capture, Cerveau.ai does the rest.
Cerveau.ai is built for founders, creative professionals, and operators who are running at full capacity across multiple active projects. If you've ever sat down to work on something and spent the first 30 minutes reconstructing where you left off, Cerveau.ai is built for you.
Each project has its own execution state — open decisions, captured notes, linked context, and suggested next actions. When you switch to a project, Cerveau.ai surfaces what's relevant to that project only. Nothing bleeds across. The market parameter is part of the context key, so the right information always surfaces for the right project.
When you open a project, Cerveau.ai generates a brief containing the current state, decisions already made, open questions still pending, the most relevant notes, and a specific suggested next action. The goal is to get from cold start to deep work in under two minutes.
€10 per seat per month on monthly billing, €8 per seat per month on annual. One tier. Everything inside — capture, linking, surfacing, focus mode, execution briefs, weekly review, and the MCP and Slack agents. No add-ons, no enterprise upgrade tier, no quote-based pricing.
