VoiceRail
Your AI finally remembers your meetings

Give your AI
a memory.

VoiceRail transcribes every meeting locally and makes it available to Claude, ChatGPT, or any AI tool — so they can summarize, follow up, and act on what was discussed.

Runs on your Mac. No cloud. No bots. Free during early access.

macOS 14.2+, Apple Silicon.

I think we should ship the API changes first, then tackle the migration. The webhook endpoint is already tested.

Agreed. Let's target Thursday for the deploy. I'll update the runbook today.

Record. Summarize. Act.

No account. No bot joining your call. No "connecting your calendar." Just press record.

1

Record everything

VoiceRail runs in your menu bar. Every meeting — Zoom, Teams, Slack, Meet — gets transcribed on your Mac. No bot joins your call.

2

Summarize your way

Send the transcript to Claude, ChatGPT, or any AI. Your prompts, your format. Get exactly the summary you need — not someone else's template.

3

Let your AI handle the rest

Your AI tracks commitments, drafts follow-ups, preps you for tomorrow's calls. It has your full meeting history — not just today's.

Zoom Microsoft Teams Slack Google Meet FaceTime

See what your AI can do.

Once your AI has access to your meetings, these workflows work out of the box — no setup, no templates, just ask.

Cross-meeting search

Ask about any topic — your AI searches across all your meetings and returns a consolidated answer with sources.

"What did the design team decide about the new onboarding flow?"

Based on your meetings from March 12 and March 18:

- Mar 12: Sarah proposed a 3-step wizard. Team was split.

- Mar 18: Everyone agreed on the wizard. Josh is building

the prototype by Friday. Sarah will write copy.

Sources: Design Sync (Mar 12), Design Sync (Mar 18)

Automated follow-up

Meeting ends, webhook fires, your AI drafts the follow-up email with action items — ready to send.

[Meeting ended: Client kickoff — Acme Corp]

[Webhook → Claude drafts follow-up]

Hi team, great kickoff today. Here's what we aligned on:

- Launch target: April 15

- Josh owns the API integration

- Sarah will send brand assets by Wednesday

Open: Acme to confirm staging access.

Daily digest

Every evening, get a summary of the day: meetings, decisions, what you owe, what others owe you.

[6:00 PM — Daily digest]

Standup (9am) → Ship API first, deploy Thursday

Design sync (2pm) → Approved onboarding wizard

You owe: Prototype by Friday, help Sarah with staging

Others owe you: Acme staging access, Sarah brand assets

Meeting prep

Before a recurring meeting, your AI reviews past meetings and surfaces open items.

"Prep me for my 2pm with the design team"

Open from last 2 design syncs:

✓ Sarah's copy draft (delivered Mar 14)

✗ Josh's prototype — due Friday, not shared yet

→ You owe feedback on Sarah's copy by EOD

Suggested agenda: prototype status, copy review, analytics

Private because there's no server.

  • Audio transcribed on your Mac — never uploaded
  • No account, no sign-up, no tracking
  • No bot joins your meeting
  • Transcripts are files on your computer — not in a database

There's no server to breach, no data to sell, no policy to trust. The AI model runs on your chip.

Customize the workflow.

VoiceRail includes a CLI, webhooks, and an MCP server. If you can script it, you can automate it.

MCP

Give Claude, ChatGPT, or any MCP-compatible tool structured access to your meetings.

$ cat ~/.claude/claude_code_config.json
{
  "mcpServers": {
    "voicerail": {
      "command": "voicerail-mcp"
    }
  }
}
CLI

Export, filter, and pipe transcripts from the command line. Your API keys, your prompts.

$ voicerail export --last \
  | claude "Extract action items with owners"
Webhook

POST transcript data to Zapier, n8n, Make, or your own endpoint when a meeting ends.

$ cat ~/.voicerail/config.json
{
  "webhook_url": "https://hooks.zapier.com/...",
  "webhook_on": "recording_stop",
  "webhook_format": "json"
}

Questions

How does the AI integration work?
VoiceRail includes an MCP (Model Context Protocol) server that gives AI tools structured access to your meeting transcripts. Once configured, Claude, ChatGPT, or any MCP-compatible tool can search across your meetings, extract action items, draft follow-ups, and more — all by reading the transcripts stored on your Mac.
Which AI tools does it work with?
Any of them. The transcript is a plain text file on your computer. Copy-paste it into Claude, ChatGPT, Gemini, or any tool. Use the CLI to pipe it directly. Set up a webhook to automate it. Or configure the MCP server for always-on access. You use your own accounts, your own API keys, your own prompts.
Is it really local? No cloud at all?
Really local. VoiceRail uses OpenAI's Whisper model running directly on your Apple Silicon chip. During transcription, the app makes zero network requests. Your audio never touches a server. The only time data leaves your Mac is when you explicitly send it somewhere (like pasting a transcript into Claude).
What meeting apps does it work with?
Any app that produces audio — Zoom, Microsoft Teams, Slack, Google Meet, FaceTime, Discord, WebEx, and more. VoiceRail captures system audio directly from macOS, so it works without plugins or virtual audio devices.
How accurate is the transcription?
With the default model, VoiceRail achieves ~2% word error rate on clean speech and ~9% overall across varied audio including noisy environments. That's comparable to cloud transcription services. The large model improves accuracy further.
Is it free?
Free during early access with the medium model included. A Pro upgrade will unlock the large model for best accuracy. One-time purchase, not a subscription.
