This is the first developer page for Pebble Index 01. Learn more at rePebble.com/index, pick one up for just $75! Here’s how I use my Index 01.

Intro

This is just the beginning of Index software development. Expect things to change! Feedback is very much appreciated, ideally as a Bug Report (Pebble app → Settings → Get Help) or as a PR to our open source Pebble mobile app https://github.com/coredevices/mobileapp.

We are building Index for ourselves. We are hackers and love to mess around with the devices we have. Our mantra is great defaults, with an open side door for hackers.

With a webhook, you can configure your Index 01 to:

• send raw voice recordings to your own app or webserver
• send transcriptions of each recordings to an agent (eg Openclaw, Claude Code, Codex etc)

With the MCP sandbox, you can add any existing or new MCP to the system prompt, enabling things like:

• routing requests to your own tools
  • Home Assistant - ’Turn on the bedroom lights’
  • Google Suite - ‘Send an email to my next meeting attendees saying I’ll be late’
  • Slack - ‘Send a hilarious gif to #random’
  • Tesla - ‘Cool down my car’
  • Spotify - ‘Play my workout playlist’

Right now, only cloud MCP servers are supported but we have internal support for local MCPs (eg KMP or WASM), which will hopefully be exposed to devs in future.

Webhooks

You can set up a webhook which will be sent on each recording, in addition to the agent execution. This means note creation, actions, etc. will still run but you can store your text/audio on your own server or have it sent elsewhere.

You can find webhook settings under the main Index tab settings. Currently, only a single webhook can be configured.

Settings explained

• Webhook URL: The URL of the webhook itself.
• Headers: Any headers to be sent along with the request, this used to be limited to just a non-standard auth header but now can be anything. Using a standard Authorization header with some form of token is recommended for basic security.
• Send: You can choose to send just the recording, just the transcription, or both.
