What is Sidebrain?

Sidebrain is your AI-powered second brain — an intelligent assistant that actually does things, not just talks about them.

Unlike generic chatbots, Sidebrain connects to your tools, remembers your context, and takes action on your behalf.

The Problem with AI Assistants

Most AI tools today have a fundamental limitation: they're disconnected from your actual work. You have to:

• Copy-paste information back and forth
• Manually update multiple tools
• Repeat context in every conversation
• Do the grunt work yourself

How Sidebrain is Different

1. Connected to Your Tools

Sidebrain integrates with the apps you already use:

• Gmail — Read, search, and draft emails
• Calendar — Check your schedule, find meeting times
• GitHub — Track PRs, create issues, review code
• Notion — Search your docs and databases
• Linear — Manage issues and projects
• Slack — Send messages and stay in the loop

2. Remembers Your Context

Sidebrain builds up knowledge about you over time:

• Your preferences and working style
• Important information you've shared
• Past conversations and decisions
• Your projects and priorities

3. Actually Takes Action

Instead of just telling you how to do something, Sidebrain can:

• Draft that email for you
• Create the GitHub issue
• Schedule the meeting
• Search your notes
• And much more

Getting Started

1. Sign up at sidebra.in
2. Add your API key (bring your own OpenAI/Anthropic key)
3. Connect your apps through secure OAuth
4. Start chatting and let Sidebrain help you work smarter

Pricing

Sidebrain uses a bring-your-own-key (BYOK) model:

• Free tier — Limited features, perfect for trying it out
• Pro ($19/mo) — Full access, unlimited conversations
• You pay your AI provider directly for usage

This means you're not locked in, and you control your costs.
