Publish more. Pay your AI provider, not us.

How it works

Two ways to write, one calendar.

Included articles and your own keys work side by side. You decide which jobs go where.

1. Add a key

Paste a key in Settings, under AI keys. Postbing checks it with a tiny test call and tells you in plain words if something's wrong: a bad key, no credit left or a model your account can't use.

2. Pick a model per job

Choose what writes your articles, what plans topics and outlines, what handles edits and what answers in research and chat. Start from a preset: best quality, balanced or lowest cost.

3. Publish beyond your bundle

Articles written on your key don't use your included articles. Your provider bills you directly, and the usage page shows estimated spend by provider and model.

The details

What happens to your key

  • Keys are encrypted before they're stored. After you save one, Postbing only ever shows its last four characters.
  • Only the account owner can add, see or remove keys. Team members' work runs on the owner's keys.
  • Rename, test again, replace or remove a key at any time.

If your key stops working

You choose what happens: carry on with your included articles (the default), or stop and tell you. Either way you get a notice, at most once a day, so a key that runs out of credit never silently stalls your calendar.

Fair use

Your plan's other limits still apply: number of sites and team seats. There's also a daily cap on articles per site written on your own keys, which keeps publishing at a pace that reads as a real blog rather than a content farm.

Bring your own keys is available on every paid plan. Your first article is free either way.

Plans

Articles included on every plan.

Your own keys add to these, they don't replace them.

Questions

Questions about keys.

Something else? Email support@postbing.com and a person will reply within 24 hours.

Which AI providers can I use?

OpenAI, Anthropic (Claude), Google (Gemini), xAI (Grok), Alibaba Cloud (Qwen), Moonshot (Kimi), OpenRouter, or any OpenAI-compatible endpoint you run or rent.

Do articles on my own key count against my plan?

No. Only articles written with the included credits count. Articles written entirely on your key don't.

Is my key safe?

Keys are encrypted at rest, never shown in full after you save them, never written to logs and only visible to the account owner.

What does an article cost on my own key?

It depends on the model you pick and your provider's prices. Postbing shows an estimate per provider and model on the usage page, so you can compare.

Do I need my own key to use Postbing?

No. Every plan includes articles each month. Keys are for publishing more, or for choosing your own models.
