Local Transcriber vs Granola — What 'Bot-Free' Actually Means

Granola markets itself as “bot-free.” No awkward AI participant joining your Zoom call. No one asking “who’s Granola?” mid-meeting.

That part is true. But “bot-free” and “private” are not the same thing.

”Bot-Free” Doesn’t Mean Private

Granola doesn’t drop a bot into your meeting. It records audio locally on your device. So far, so good.

Then it sends that audio to the cloud.

Granola routes your meeting audio through Deepgram and AssemblyAI for transcription. Your summaries are generated by OpenAI or Anthropic servers. Your words leave your machine, travel to third-party data centers, and get processed on infrastructure you don’t control.

This isn’t speculation. Granola names these providers on its own security page. The product doesn’t work without them.

So when Granola says “bot-free,” they mean no visible bot in your meeting. They don’t mean your audio stays on your device. Those are very different promises.

The Trust Problem

In a 2025 security incident, an exposed AssemblyAI API key left transcripts from 333 iOS beta testers accessible without authentication. Granola patched it the same day it was reported, and the production Mac app was not affected. But the question it raises isn’t gone: if your transcripts live on someone else’s servers, you inherit their security posture.

There’s also the consent question. Because there’s no bot, there’s no visible indicator that recording is happening. Other participants don’t know their words are being captured, transcribed, and sent to Deepgram or OpenAI. Granola offers an optional consent message feature, but it’s not on by default.

Bot-free solves one problem (meeting disruption) while obscuring another (data exposure).

The Real Difference: Where Your Audio Goes

This is the core of it.

When you record a meeting with Granola, your audio gets captured locally, then shipped to Deepgram or AssemblyAI for transcription. The transcript then goes to OpenAI or Anthropic for summarization. Your meeting audio touches at least two third-party cloud providers before you see a result.

When you record a meeting with Local Transcriber, your audio stays on your Mac. Apple’s on-device speech recognition handles transcription. Speaker diarization runs locally. The transcript saves as a .md file to a folder you choose. Nothing is transmitted. Not the audio, not the transcript, not anonymized telemetry.

You can verify this yourself: turn on Airplane Mode and record a call. Local Transcriber works. Granola doesn’t.

When Granola Makes Sense

Granola is a good product for a specific use case.

Choose Granola if:

• You want polished, AI-generated meeting summaries and don’t mind cloud processing
• You work on a team that needs shared meeting notes and collaboration features
• You need integrations with tools like Notion, Slack, or your CRM
• You trust Deepgram, OpenAI, and Anthropic with your meeting audio
• The $14/month subscription fits your budget and workflow (free tier available with limited history)

Granola’s summaries are genuinely useful. If privacy isn’t your primary concern and you value team collaboration features, it’s a capable tool.

When Local Transcriber Makes Sense

Choose Local Transcriber if:

• You need true privacy. Not “bot-free” privacy. Actual on-device, nothing-leaves-your-Mac privacy.
• You work in legal, healthcare, finance, HR, or any field where meeting content is sensitive
• You want .md files on disk that your AI tools can read directly. Claude Code, Claude Desktop, Cursor, or any MCP-connected agent can access your transcripts from the filesystem. No API setup, no authentication, no cloud dependency.
• You don’t want a subscription. $20 once. That’s it.
• You want to verify the privacy claim yourself (Airplane Mode test)
• You want transcripts that work offline, that you own as files, and that no third party can access, subpoena, or leak

Frequently Asked Questions

Is Local Transcriber really 100% offline?

Yes. Local Transcriber uses Apple’s on-device speech recognition engine. Your audio never leaves your Mac. No network calls, no API keys, no cloud fallback. Turn on Airplane Mode and test it yourself. See the full feature breakdown for details.

Can Local Transcriber generate meeting summaries like Granola?

Yes. Local Transcriber generates on-device summaries included in your .md transcript file. The summaries are produced locally, not by sending your transcript to OpenAI or Anthropic.

Does Local Transcriber work with Zoom, Google Meet, and Teams?

Yes. It captures system audio directly from your Mac, so it works with any app that plays audio. No meeting link or integration required. See our step-by-step guides for Zoom, Google Meet, and Microsoft Teams.

Why does Local Transcriber output .md files instead of using a cloud dashboard?

Markdown files are portable, searchable, and readable by any text editor or AI tool. Your AI agent (Claude Code, Claude Desktop, Cursor) can read .md files directly from your filesystem. No API, no export, no copy-paste. The transcript is just a file on your disk, ready for whatever you need.
