On-device vs cloud transcription: what actually changes

"Transcription" sounds like a single thing, but where it happens changes almost everything about privacy. When you record a meeting, there are really three questions: where the audio goes, where the text goes, and who can read either of them later.

What happens in cloud transcription

With a cloud service, your meeting audio is uploaded to the vendor's servers. There, it is turned into text, usually summarised, and stored so you can open it from any device.

That is genuinely convenient. It also means:

• A copy of the conversation lives with the vendor. Audio, transcript, or both, depending on their policy.
• Access depends on their systems. Their security, their employees' access rules, their subprocessors and their retention settings all apply to your meetings.
• Their terms decide what happens next — how long data is kept, whether it can be used to improve their models, and what happens if you cancel.

None of this is automatically bad. Many cloud vendors take security seriously. But it is a different trust model: you are handing a record of your conversations to a third party.

What happens on-device

With on-device transcription, the speech model runs on your own computer. The audio is turned into text locally and never uploaded.

In MeetInk, that covers the whole recording pipeline:

• Your microphone and the meeting app's audio are captured on your Mac.
• Speech recognition and speaker separation run locally.
• The recording, transcript and notes are stored on your Mac.

There is no copy on anyone else's server, because nothing was sent.

The step people forget: the summary

Transcription is only half of a meeting note. Someone still has to turn an hour of talk into decisions and action items — and that usually means a large language model.

This is where "local" apps can quietly stop being local. An app can transcribe on your device and then send the full transcript to a cloud model, or sync the notes to its own servers.

MeetInk makes this choice explicit:

• Fully offline: a local model through Ollama writes the notes. The transcript never leaves your Mac.
• Your own key: Google Gemini (the recommended free option), Claude or OpenAI writes the notes using your API key. Only the transcript text is sent — never audio — and it goes straight from your Mac to that provider. On Gemini's free tier, Google may use it to improve its models; the paid tier doesn't.

Either way, the app itself does not store your meetings anywhere else.

Does on-device mean worse quality?

It used to. Modern speech models that run on Apple silicon are fast and accurate enough for real meetings, including separating who said what. Where cloud services still lead is breadth: more languages, and features that depend on a shared server, like team workspaces.

MeetInk transcribes English today. If you record calls in several languages, a cloud service may serve you better.

Why it matters for real work

For some meetings, none of this matters. For many it does:

• Client calls often include systems, data and plans your client did not agree to share with your tools vendor.
• Sales calls include pricing, discounts and deal terms.
• Interviews and 1:1s include personal information and feedback.
• Incident reviews can include details of security problems.

Keeping these on your own machine is the simplest way to keep them out of places they should not be.

Questions to ask any notetaker

1. Is the audio processed on my device or uploaded?
2. After transcription, where are the transcript and notes stored?
3. Which AI writes the summary, and what does it receive — audio or text?
4. Is an account required, and what happens to my data if I stop paying?
5. Does anything join the meeting that other participants can see?

If an app cannot answer these plainly, that is an answer too.

The short version

Cloud transcription trades control for convenience: your conversations live with a vendor so you can reach them from anywhere. On-device transcription keeps the only copy with you. MeetInk is built on the second model — and lets you decide, per setting, if anything should ever leave your Mac.
