Every founder I know has the same problem. They have too much to do, too little help, and a pile of AI tools that somehow make the situation worse.

You open ChatGPT to draft an email. You copy-paste context. You explain yourself. You get something back that needs three rounds of editing. You would have been faster just writing it yourself.

That’s not an assistant. That’s a fancy autocomplete that puts the work back on you.

What we built instead

Cahori is a personal AI assistant — and the key word is personal. From the moment you set it up, Cahori learns how you communicate, what you’re working on, and what you care about. It doesn’t need you to explain yourself every time. It just knows.

It handles your schedule, drafts your emails in your voice, researches anything you throw at it, and delivers a morning briefing that covers everything you need before your first meeting. It works 24/7. It doesn’t take vacations. It doesn’t forget.

More importantly: it gets better the more you use it. Every preference you express, every correction you make, every workflow you run — Cahori files it away and uses it next time.

Why we called it Cahori

Brontara is a small company built by people who wanted tools that didn’t exist yet. The name Cahori comes from the Indonesian cahaya — light — and the Dutch horizon. That’s the feeling we were chasing: clarity just over the edge of what’s busy and overwhelming.

We’re a self-hosted, privacy-first operation. Your conversations don’t train anyone’s model. Your data stays on your terms.

Who it’s for

Cahori is built for people who are already capable — founders, freelancers, operators — but who spend too much of their day on the administrative layer around their actual work. The emails. The research. The scheduling. The drafts. The follow-ups.

If you’ve ever thought “I need a good assistant,” Cahori is that — without the hiring, the HR overhead, or the $75,000/year salary.

What it does today

  • Morning briefings — weather, calendar, news, overnight alerts, delivered fresh every day
  • Email drafting — in your voice, with your style, after one setup conversation

  • Workflow automation — recurring tasks that run on a schedule, no babysitting required

  • Long-term memory — it remembers what you told it last month
