Communication as a deliberate act, not an automated one.

Most outreach tools optimise for volume. Send thousands, hope a few respond. That approach is broken. Not just ethically, but strategically.

Cold AI takes a different approach. We ensure that when a message exists, it's justified. Signals and context first. Research before reach.

The system won't generate until it understands what you're selling, who you're selling to, and why this specific person would care. No templates or variables, but instead messages that could only be sent to one person.

What the API does

Research your prospect. Generate a message.

Research your profile

The API analyses your user profile and value proposition to understand how you help your customers.

Analyse prospects

Deep research into each LinkedIn prospect. Their role, company, recent activity, and potential pain points.

Generate messages

Personalised, contextually relevant messages crafted specifically for each prospect. No templates or generic phrases.

Proven methodologies

Apply established outreach frameworks that respect the recipient while maximising relevance.

Idempotent requests

Safe retries with idempotency keys. Duplicate requests return cached results without extra charges.

Webhook notifications

Get notified when users connect, LinkedIn auth completes, or long-running operations finish.

End-to-end endpoint

Single API call. Research and generate in one request.

Perfect for simple integrations. Pass a LinkedIn profile URL, receive a researched, personalised message.
