Butr

AI-native investing control for UK ISAs

Connect your Trading 212 API key. Ask your favourite AI to build trades. Butr previews, validates, and creates execution-ready tickets you approve before anything happens.

Pre-launch Stocks & Shares ISA only

How it works

No in-app chat needed

Connect your Trading 212 API key to Butr securely.
Use any AI chat (ChatGPT, Claude, etc.) to describe your trade intent.
Butr creates a portfolio-aware preview with validation checks.
Approve the ticket. Only then does anything execute.

Why Butr

Human-in-the-loop: every trade requires your approval

Bring your own AI: works with any chat client
UK-focused: built for ISA compliance

What Butr is not

Staying focused

No autonomous trading or robo-advisor
No social trading or copy features
No portfolio dashboard (use Trading 212 for that)
No live execution in v1 (approval tickets only)
