# Use Syntheo without a network

> What works without an internet connection and what requires a reachable inference server.

Syntheo needs the internet for none of its features: it has no account, no sync and no online service. What it needs is **your inference servers**. If they run on your computer or on your local network, everything works offline. If they are unreachable, the features that depend on them stop.

## What always works

These features call no server:

* creating, editing and organizing your notes and folders;
* reviewing transcripts and summaries already produced;
* full-text search (local index);
* exporting your notes;
* managing your summary templates.

## What requires the transcription server

* meeting transcription;
* dictation;
* importing an audio file.

Without a reachable transcription server, **there is no transcription**. Syntheo never keeps audio: so it cannot record now to transcribe later.

* If no transcription provider is set up, Syntheo refuses to start the capture: "No transcription provider is set up. Syntheo does not keep audio: set up a transcription endpoint before recording."
* If the server becomes unreachable during a meeting, live transcription pauses and Syntheo tries to reconnect. The passage spoken during the outage will be missing from the transcript.

## What requires the summary server

* generating summaries;
* chatting about notes ("Ask the note");
* "Suggest sections" in the template editor.

Without a reachable summary server, your transcripts remain available: you can generate the summary once the server is back.

## Work entirely offline

**1. Install the servers on your computer or local network**

For example speaches or vLLM for transcription, Ollama or llama.cpp server for the LLM. Download the models **before** you disconnect.

**2. Declare them in Syntheo**

Follow [Set up transcription and AI](https://docs.syntheo.studio/en/ai-setup.md) with local URLs, for example `http://localhost:8000/v1` and `http://localhost:11434/v1`. Plain HTTP is accepted toward `localhost` and private addresses.

**3. Test before the meeting**

Run a short listening session, then generate a summary. If both work with the network cut off, you are ready.

> [!NOTE]
>
> Apart from inference, Syntheo makes very few requests: showing the release notes of a version other than the installed one (GitHub) and a few interface icons. They carry no meeting content and their failure blocks nothing. Full list in [Syntheo Desktop and the GDPR](https://docs.syntheo.studio/en/conformite/rgpd.md).
