Features

• Chat with Pluto about a meeting, person, or project. Ask follow-up questions in a meeting chat, focus on someone’s history, or explore a project—with references back to the conversations.
• Keep people and projects organized. See their past conversations, decisions, and next steps in one place.
• Track everyone’s commitments. Keep track of who promised what across conversations, including your own follow-ups. Get reminders for confirmed commitments with due dates.
• Follow project milestones. Keep milestones, decisions, and open work connected to the meetings behind them.
• Recognize familiar voices with Voice ID. Confirm speaker matches and correct them when needed, so you can follow who said what.
• Record without a bot. Capture your microphone and Mac’s audio directly, then review transcripts, notes, and next steps.
• Choose where AI runs. Use local models through Ollama or an optional cloud provider.
• Bring notes into ChatGPT. Enable the optional connection on the same Mac. See what’s shared →

How it works

1. Record. Start a meeting in Pluto and carry on with your conversation.
2. Review. Stop recording, let Pluto transcribe and generate notes, then check the decisions and next steps.
3. Pick up the thread. Ask a question or explore the people and projects connected to your meetings.

Let participants know when you record. Generated notes, answers, and speaker matches can be wrong—review the source when it matters.

Get started

You’ll need an Apple Silicon Mac (M1 or later) with macOS 14.2 or later. An internet connection is required for initial downloads.

1. Install Pluto

curl -fsSL https://raw.githubusercontent.com/metagrover/pluto/master/scripts/install-macos.sh | bash

Complete setup to download speech models and allow microphone and system audio access. Calendar access is optional.

2. Set up Ollama

Install and open Ollama, enable its command-line tool, then download the models for notes and chat:

ollama pull gemma4:12b && ollama pull phi4-mini:3.8b

Pluto uses these models by default. Keep Ollama running when using notes and chat.

3. Try your first recording

Let participants know you’re recording, then click New meeting. After the meeting, stop recording to generate notes and ask follow-up questions.

Meeting notes, decisions, and next steps

Review notes and next steps, then ask Pluto follow-up questions in the meeting’s chat. Confirm familiar speakers with Voice ID and correct matches when needed.

Ask Pluto and check the source

Ask across your meeting history, or focus the chat on a person or project. Follow references back to the conversations behind the answer.

People, projects, and follow-through

Open a person’s page to catch up on your conversations and their commitments. Open a project’s page to review its decisions, milestones, and open work. Track commitments for everyone involved, with reminders for confirmed due dates.

Pick up the thread in ChatGPT

The optional Pluto plugin brings meeting notes into ChatGPT on the same Mac. Connect ChatGPT →

Privacy

• Capture and transcription run on your Mac. Local intelligence also stays on your Mac. Optional cloud AI sends the text needed for each operation to your chosen provider, which can include transcripts, notes, and retrieved context.
• Database encryption is optional at setup. Audio files are not encrypted by default. Storage details →
• ChatGPT access is optional. Enabling it makes all meeting notes available to read. Retrieved notes go to OpenAI; raw transcripts and audio are excluded. Disabling stops future reads; notes already shared remain in ChatGPT.

FAQ

Can I use Pluto offline?

Yes, after downloading the speech and Ollama models, local recording, transcription, notes, and chat work without a cloud provider or API key. Cloud AI and the optional ChatGPT connection need an internet connection.

Do I need a subscription?

Pluto is free and open source. You can use local intelligence without an API key. If you choose cloud AI or ChatGPT, their own pricing and access requirements apply.

Does Pluto support Intel Macs, Windows, or Linux?

Currently, Pluto supports Apple Silicon Macs only.

Where can I get help?

Start with the setup guide and troubleshooting. In Pluto, Help → Report a Problem prepares a report you can review before sharing. Keep private meeting content and credentials out of public issues.
