Your evidence-first growth workspace

Know what to do next.
Learn from what happens.

Paste your product URL. PostBeacon verifies the facts, chooses one useful growth experiment, prepares the draft, and turns the result into your next move.

No auto-posting. Every draft passes a truth check; you review and publish by hand.

From product facts to the next learning

Not another report to file away. One focused loop you can finish, learn from, and repeat.

1

Verify the facts

Paste your URL. PostBeacon separates what the page actually says from what is inferred or still unknown.

2

Choose one experiment

See the next best channel, audience, angle, and signal to watch — with the reason it beats the alternatives.

3

Publish with control

Edit a platform-native draft, pass the truth check, and publish it yourself. PostBeacon never posts for you.

4

Measure and adapt

Record the 24h and 72h signals. PostBeacon explains the result and turns it into the next experiment.

Score every channel. Act on one.

PostBeacon evaluates 19+ platforms across 8 categories, then brings one evidence-backed next move to the front. The full ranking stays available when you need it.

FAQ

Does PostBeacon post for me automatically?+

No — and that's deliberate. PostBeacon prepares and truth-checks the draft, but you review every change and publish it yourself. Confirming the publish starts the 24h/72h result loop.

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

It builds a fact ledger from your URL, then scores every platform for audience, intent, native-content fit, founder access, and risk. You get one next best experiment first; the full ranking remains in the Strategy library.

Is this another marketing report I use once?+

No. The initial analysis opens into a workspace: prepare one experiment, publish manually, record the 24h and 72h signals, receive an explainable verdict, then act on the next experiment. The product becomes more useful as your project accumulates real evidence.

Which AI model does it use?+

OpenAI or DeepSeek in the current beta — you choose the primary from whatever the deployment has configured. If the primary model is unavailable, PostBeacon may retry with another configured provider. During this beta that can include DeepSeek, which processes data in China and does not clearly exclude training use; avoid confidential material. The picker and Privacy page explain what data is sent.

Where does my data live?+

Before sign-in, the one-channel preview is processed by the server and AI provider but is not written to the project database. Its result stays in this browser for up to one hour for an explicit sign-in handoff. Signed-in projects use owner-only Supabase rows. You can export or delete your account data in the app.

Who is it for?+

Vibecoders and indie makers with a live product who need their first users, but don't want a generic content machine or another plan they still have to translate into action.
