Frequently Asked Questions

Common questions about OnePost.

General

What is OnePost? OnePost converts your newsletter into platform-native social media posts for X, LinkedIn, Threads, Reddit, Bluesky, Xiaohongshu, and Instagram using AI. The posts feel like they were written by a human who lives on each platform — not copy-pasted newsletter excerpts.

How many posts can I generate for free? Free accounts get 5 generations per day. Each generation creates all 7 platform posts at once.

What's included in Pro? Pro includes unlimited generations, API access, advanced brand voice features, team sharing, and priority support. $19/month.

Does OnePost work with any newsletter platform? Yes. OnePost works with any content you can paste or any RSS feed. Native optimization for Beehiiv and Substack included.

Content & Quality

How good is the output? The output is good enough to post directly on most platforms, though you'll want to review and add personal touches. The AI understands platform-specific formats, character limits, and audience expectations.

Can I adjust the output? Yes. Use Brand Voice to steer the style. After generation, you can edit the text before copying.

Does it support Chinese? Yes. Xiaohongshu posts are always generated in Chinese. For other platforms, use the language selector to choose between auto-detect, English, or Chinese output.

Technical

Is my content stored? Newsletter content is sent to Google's Gemini API for generation and is not stored by OnePost. Generation history is stored so you can reference past outputs.

What AI model does OnePost use? Gemini 2.5 Flash by Google DeepMind.

Can I use the API? Yes, on Pro. See the [API documentation](/developers).

Account & Billing

How do I cancel? Cancel anytime from Settings → Subscription. You keep access until the end of the billing period.

Do you offer refunds? Yes, within 7 days of purchase with no questions asked. See our [refund policy](/refund).
