KACO Cold Outreach AI – Write Hyper-Personalised Cold Emails & LinkedIn Openers in Seconds

Stop spending 20 minutes researching every prospect just to write one opening line.

Cold outreach lives or dies on personalisation. Generic openers get ignored. Researched, specific messages get replies.

But doing that research manually — reading LinkedIn profiles, scrolling company pages, looking for the right hook — eats your whole morning before you’ve sent a single email.

KACO Cold Outreach AI fixes that.

Paste whatever you know about a prospect — their LinkedIn bio, company About page, a post they made, anything — and the app generates three personalised opening lines or a complete cold email in seconds. Powered by gpt-4o via your own API key, so the output is sharp, not generic.

What You Get

⚡ Two output modes:

• 3 Opening Lines — three short, punchy openers using different angles (curiosity, compliment, shared context). Perfect for LinkedIn DMs and connection requests.
• Full Cold Email — complete email with subject line, personalised opening, value prop, soft CTA, and sign-off. Under 130 words. Ready to paste into Gmail or Outlook.

🤖 Three AI options in one tool:

• OpenAI gpt-4o — live call using your own API key. Fastest and most seamless.
• Open in Claude — one click sends your prompt to claude.ai, ready to run.
• Open in Gemini — one click sends your prompt to Gemini. Great free option.

🔒 Your data stays yours: The tool runs entirely in your browser. Your API key is stored locally — never on our servers. You can safely use it with real client data, sensitive prospect lists, and internal contact databases.

🌑 Light & dark mode — switches with one click and remembers your preference.

📱 Works on any device — desktop, tablet, or mobile. Chrome, Edge, Firefox, Safari.
