How it works
Before, during and after — one sales call, one flow.

Trust
What it does, and what it won’t.
What it does
- Listens to the sound on your own computer. It joins nothing and appears in no participant list.
- Searches your knowledge base on your device. Price lists, spec sheets and contracts are not uploaded to a server for storage.
- Writes every answer in the first person, from what you uploaded, with the file and page it came from.
- Keeps its window out of your screen share: excluded from screen capture on Windows, excluded from single-window shares on macOS.1 A built-in self-test tells you what your machine can exclude before the call starts.
- Deletes the transcript after the conversation. Audio is never stored. What remains is the debrief and the notes you asked for.
What it won’t do
- Speak to your customer or close for you. It feeds you verified facts; the selling is still yours.
- Invent a number. Where your documents are silent, it says so rather than filling the gap — a confident wrong figure costs more than a pause.
- Write into your CRM. Today no connector reads or writes your data; once one does, entries will come back as a draft you release, never as an automatic write.
- Hear a phone held to your ear. By default it hears only what comes out of your speakers — a video call, or a phone call routed through the machine.
- 1On Windows the window is excluded from window shares, full-screen shares and screenshots alike. On macOS it is excluded when you share a window or a single application. For a full-screen share on macOS 15.4 and newer it cannot be assured: Apple withdrew the interface this relies on. The app checks your machine and tells you which of the three it can exclude, rather than letting you find out mid-call.
FAQ
The questions sales teams ask first.
Does Thalassa join my sales call?
No. It is not a meeting bot: it listens to the sound on your own computer, joins nothing and appears in no participant list — on Zoom, Teams, Meet, Webex or a phone call on speaker. There is no platform integration to configure and no admin approval to chase, on your side or the customer’s.
Is it recording my calls?
No. Audio is never stored — it is streamed for transcription and discarded. The transcript exists only during the conversation and is deleted afterwards; what remains is the debrief and the notes you asked for. Your price lists and contracts are searched on your device and are not uploaded to a server for storage.
Am I allowed to use this in a sales call?
In a professional conversation where you are expected to have the right information, yes — and only where assistance is permitted. Whether the other side must be told depends on where you are. In the United States, consent to recording or transcribing a call is governed state by state: many states let one party’s consent suffice, while all-party-consent states — California, Florida, Illinois, Pennsylvania and Washington among them — require every participant to agree before a call is recorded or transcribed, and a transcript is a transcript whether or not it is kept. Several other countries have the same rule. Where it is not permitted, using Thalassa is not permitted — that is in the terms (section 2), not just here. Rehearsing with it beforehand is always yours to decide.
Does it write into our CRM automatically?
No — and today it does not write at all: no connector reads or writes your data. The sign-in path for Salesforce and HubSpot is built and tested; reading and writing are at different stages per system, and how far each has come is on the connectors page. Once that part is built, the debrief will come back as a draft — a note on the opportunity and, if you release it, updated stage, close date or next step. Nothing would be written without you releasing it.
Do our price lists leave the company?
The knowledge base is searched on your own machine. Documents are not uploaded to a server for storage; the transcript is deleted after the conversation and audio is never stored. Answers are generated in the EU. Two exceptions, named rather than hidden: web search and optional live translation leave that path, and both can be switched off. How your data is handled.
What happens if the answer is not in our documents?
It says so. It does not fill the gap with something plausible — an unsupported number in a sales call is the expensive kind of mistake. The internet is a fallback you can switch on, and an answer from it is marked as such.
Can the customer see it?
On screen, no: the window is excluded from what you share,1 there is no sound, no notification and no extra participant in the call. What the customer may notice is you reading — someone reading an answer aloud sounds like someone reading aloud. That is why you get bullet points and not a script, and why rehearsal mode exists.
Is there really a free first meeting?
Yes. Install the app and create an account — the first meeting is free, with up to 15 minutes of live answers, plus 5 preparations (briefing, debriefing or scenario workshop), knowledge base capped at about 100 pages. A preparation does not use up the free meeting. It is granted in the app, once per account; no card required.
