Universal API for Personal AI

One token.
Every service.

Your AI assistant can read your email and check your calendar. But it can't see your runs, your bank balance, or your health data. OneToken gives it a single key to everything you've authorized.

The problem with personal AI

01

Fragmented access

Every service has its own API, its own auth flow, its own token format. Your AI can't navigate that maze.

02

Built for developers, not people

Existing unified APIs like Composio and Nango target B2B SaaS companies. Nobody built this for individuals.

03

Your data is personal

Fitness data, financial data, health metrics. These require consumer-grade auth and privacy, not enterprise dashboards.

04

AI agents are going agentic

Claude, ChatGPT, and Gemini are all adding tool use. They need a standard way to access your authorized services.

Three steps. That's it.

Connect your services once. Your AI handles the rest, forever.

01

Connect your apps

Authenticate the services you use daily. Fitness trackers, banking, health apps, productivity tools. A simple consent screen, no code required.

02

Get your token

OneToken issues a single unified token. Hand it to any AI assistant, bot, or agent. One credential replaces dozens of individual API keys.

03

Your AI acts across everything

Your AI can now query your running data, check your spending, and pull your health metrics through unified endpoints. No per-service configuration.

The universal authentication layer for the age of personal AI. Your data, your token, your rules.
