For partner-led accounting and consulting firms
Answers your firm
can stand behind.
Cited to the source, limited to what each person is cleared to see, and answered as of any date you choose. The AI assistants your firm uses can work through it too.

Three sources. One connected answer.
Answers
Answers you can stand behind.
An answer is only useful to a partner if it can be checked. Louvain checks it before you see it.

- checked
Figures, dates and names are checked
Each one is checked against the source that states it. A sentence whose figure, date or name no source supports is removed from the answer.
- inferred
Recorded is kept apart from implied
What the sources say is the answer. What they only imply is shown separately, marked as inferred, and never stored as fact.
- refused
No support, no answer
When nothing you can see supports an answer, Louvain says so and shows what the sources do establish, instead of guessing.
- as of
Any date you choose
Ask as of a date and the answer comes from what the firm’s sources had said by then, with later changes set aside.
Confidentiality
Client confidentiality, enforced automatically.
Every answer is limited to what the person asking is cleared to see. The limit is applied as the data is read, so two people asking the same question get answers built from what each of them may read.
- Jordan removed from #harbourline-audit in Slack
- Louvain receives the membership change
- The channel leaves the sources Jordan can read
- Jordan’s answers no longer draw on it
- follows the source
Cleared by the source’s own sharing
A Drive file follows its sharing and a Slack channel its members. Where a source has no permissions to report, an administrator chooses who may read it.
- applied on read
Checked as the data is read
The check is part of the query that retrieves evidence, before anything is ranked or written. Nothing a model writes can widen what anyone may read.
- access removed
Remove access, and answers change
Once a source reports that someone has lost access, their answers stop drawing on it.
- roles
Administration unlocks nothing
Partners who run Louvain manage it. Their role does not let them read client work they are not cleared to see.
AI tools
Works with the AI you already have.
The confidentiality layer under every AI tool your firm uses. AI assistants connect through Louvain and see only what their user may see. No new platform, and nothing to build.
An assistant asks, as the person using it
“What did we agree with Harbourline on fees?”
Claude · connected to Louvain · signed in as you
Louvain answers from what you may read
Harbourline agreed a fee cap of £24,500.
Gmail · Harbourline engagement · 20 Jun
- remote MCP
Connects in a few steps
Add Louvain as a remote MCP server and approve access once. It works with Claude, Claude Code and Cursor, among others.
- as the person
Never more than its user
An assistant reads with the access of the person who approved it. It cannot share anything, change settings or connect sources.
- checked
The same checked answers
Answers an assistant gets from Louvain are checked the same way, figure by figure, and come with their sources.
- disconnected
Ended at once
Disconnect an assistant and its access ends immediately.
Plate
Nothing you promise a client slips.
Plate lists what clients and colleagues asked of you, in their words. An item closes when a later message settles it, and shows you the sentence that did, or when you say so. When Louvain isn’t certain, it shows you the sentence and asks.
