Souffleur listens to your client calls and whispers to you as soon as a statement doesn't match your documents. With the page number. The other side notices nothing.
Act I · The problem
Nobody knows every detail of the whitepaper, price list and contract by heart. In a call there's no time to look it up, so people guess. The mistake only shows when it gets expensive.
01
A delivery date, a data location, a feature. Once it's said, it's on the table and later in the contract.
02
“Let me check and get back to you” postpones the decision. Whoever has the answer right away leads the conversation.
03
Meeting notes summarize what was said. Nobody checks whether it was right.
Dramatis personae
Act II · How it works
1. Pick your documents
PDF, Word, PowerPoint, Excel, whole folders or code repositories. Your files stay where they are.
2. Have your call
The app listens to your microphone and the other side's audio and transcribes locally. No bot joins the meeting.
3. Get the hint
When a checkable statement comes up, a discreet hint appears. Everything else stays quiet.
Act III · The app
Start in seconds
Pick documents and a check profile. The notice to the other participants is included.
Live history
Checks appear right under the sentence. Promises are noted automatically.
Discreet in person
Planned: the hint arrives as a vibration on your smartwatch.
Act IV · Use cases
Presales & sales
Features, security, rollout time, pricing. Souffleur checks every promise against docs, whitepapers and price lists before it ends up in the offer.
Typical documents: Product docs, security whitepapers, price lists, roadmap
COLLEAGUE
Rollout takes two weeks for us.
→ Enterprise onboarding: four to six weeks including SSO setup. Onboarding.md, section 2
Advisory & compliance
Statements about costs, risks and terms are checked against product documents. The report records what was corrected during the call.
Typical documents: Product sheets, key information documents, internal policies
ADVISOR
There's no front-end load on this product.
→ A front-end load applies. KID.pdf, p. 2
Engineering & product
Claims about code, configuration and history are checked directly in the repository, including Git history.
Typical documents: Git repositories, specs, tickets, configuration
DEVELOPER
The export doesn't use the DTO at all.
→ ExportService serializes ArticleDto directly. ExportService.java:42
In-person meetings
Your phone lies on the table and the hint arrives as a discreet vibration on your smartwatch. Nobody notices. (Planned)
Typical documents: Terms, warranty conditions, offers
CLIENT
The warranty is five years, right?
✓ Five years manufacturer warranty, extendable. Warranty.pdf, p. 1
Act V · After the call
After every call you see which statements were confirmed, which were wrong and whether they were corrected during the call. Uncorrected points become a correction in your follow-up email at the push of a button.
Act VI · Privacy
Built in Germany. As little as possible leaves your device.
(The audio stays on your computer. So does speech recognition.)
(Only the two or three sentences at stake go to the AI model for checking.)
(The souffleur only reads. It doesn't write, send or delete anything.)
(Whoever is being listened to knows it: if you want, a notice goes into the meeting chat.)

Epilogue · Questions
All participants must be informed and agree. The app can post a notice in the meeting chat automatically when it starts. The exact obligations depend on country and industry, so please check them with your legal or compliance team.
No. Hints only appear on your screen and are hidden when you share it. No bot joins the meeting either.
Any tool that plays audio on your computer, for example Microsoft Teams, Zoom or Google Meet. The app listens to your microphone and system audio, regardless of the tool.
Audio and speech recognition stay local. For checking, only short transcript snippets and the matching passages of your documents are sent to the AI model. For enterprise setups, the model can run in an EU region or on your own infrastructure.
German and English. More languages will follow.
Every hint shows its source, so you can check it with one click. If Souffleur finds nothing solid, it stays silent.
Finale
Bring a real document, a whitepaper or a price list. We play through a client call, and you see for yourself when the souffleur steps in. 30 minutes, directly with the developer.
We're looking for our first pilot customers. You get a personal setup, a direct line to the developer and better terms. We keep building based on your feedback.
