Your AI Chief Marketing Officer

Paste a URL.
Launch everywhere.

PostBeacon scans 20+ platforms, ranks where to go all-in for your product, and writes ready-to-post content + a launch calendar. Built for vibecoders who'd rather ship than market.

No auto-posting. You stay in control — copy, tweak, ship.

From URL to launch in four steps

1

Drop your URL

PostBeacon reads your landing page and distills a sharp product profile — value, audience, differentiators.

2

Review the profile

Tweak anything that's off. You're the founder; the AI is your CMO, not your replacement.

3

Get your strategy

Every platform scored & ranked for your product, with positioning and the exact angle to use on each.

4

Ship the content

Native, ready-to-post copy per platform + a launch calendar. Copy, post, mark done.

One scan. Every channel that matters.

FAQ

Does PostBeacon post for me automatically?+

No — and that's deliberate. Auto-posting gets accounts flagged and banned. PostBeacon writes native, ready-to-post content and a calendar; you copy and post, staying fully in control.

How does it know which platforms are right for my product?+

It builds a profile from your URL, then scores every platform in its universe for fit to your specific product and audience — so a fintech tool and a dev library get very different plans.

Which AI model does it use?+

Claude or OpenAI — switchable. Bring your own API key.

Is my data saved?+

Only if you sign in. Projects are stored to your account (Supabase) with row-level security so only you can see them. Without signing in, nothing is persisted.

Who is it for?+

Vibecoders and indie makers shipping to the English developer/startup community who want a real go-to-market without hiring a marketer.
