01 · The client changes direction
Find the relevant fact while they ask.
Bring up the passage from the report, mandate file or standard without breaking the conversation.
Advisory calls
Answer from the client file — during the call.
Thalassa searches your reports, standards and past project notes on your device and shows the answer with the section it came from. If the file does not cover the question, it says so.

Three situations
Answer the client from the file, not from memory.
Thalassa searches reports, standards and project notes on your device and shows the sourced answer during the client call. Upload documents in any language; Thalassa answers in the conversation language. Live translation is optional per session.
02 · A consequence needs support
Explain it from the project record.
Use the exact section from a project note or change request instead of relying on memory.
03 · The file has a gap
State the limit clearly.
If the material does not cover the question, Thalassa says so rather than turning an assumption into advice.

How it works
Before, during and after — one client call, one flow.
The film below shows the desktop app and the assistant overlay in the current release, with example content. English release.
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. Mandate files, reports and client documents are not uploaded to a server for storage.
- Writes every answer in the first person, from what you uploaded, with the file, page and section it came from.
- Says when the documents do not cover a question — in as many words, in the answer window, and already in the briefing.
- Keeps its window out of your screen share: excluded from screen capture on Windows, excluded from single-window shares on macOS.1
- Deletes the transcript after the conversation. Audio is never stored. What remains is the debrief you asked for.
What it won’t do
- Give the advice or decide anything. It puts the facts in front of you; the judgement stays yours — which is the part you are paid for.
- Produce something plausible where the material does not support an answer. A confident wrong statement in an advisory conversation is a liability, not a rough edge.
- Write into your systems. 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 advisers ask first.
Does Thalassa join my client 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 client’s.
Is the conversation recorded?
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 you asked for. Your reports and mandate files are searched on your device and are not uploaded to a server for storage.
Am I allowed to use this with clients?
Professional codes and client confidentiality come first. Whether you may have a client conversation transcribed, and whether the client must be told, is governed by your professional rules and by where you are: many countries let one party’s consent suffice, several US states require every party to consent before a call is recorded or transcribed, and a profession bound to secrecy answers to its own code before any product’s terms. Thalassa does not make that decision for you. What it does is keep the decision small: the transcript is deleted after the call, audio is never stored, and your documents stay on your machine. Where aids are not permitted, using Thalassa is not permitted — that is in the terms (section 2), not just here.
How good are the answers outside my specialty?
As good as the material you put in. With the firm’s reports and standards in the knowledge base, an answer from a neighbouring field is grounded in a real document, with its section — and where nothing covers the question, it says so instead of guessing. The briefing tells you before the call what the file does not cover.
Can the minutes go into our systems automatically?
Today no connector reads or writes your data. The sign-in path for Microsoft 365, Google Workspace, 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, entries will come back as a draft you release, never as an automatic write.
Does the client notice?
On screen, no: the window is excluded from what you share,1 there is no sound, no notification and no extra participant. What the client may notice is you reading — which is why you get bullet points and not a script. Whether you tell them is your decision, and it depends on your country, the kind of conversation and your profession; Thalassa does not make that decision for you.
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.
