PostSider includes focused AI help for the part of publishing that benefits most: getting the wording right and catching problems before a post goes out. It does two things: it rewrites your captions, and it scores your posts. There is no separate chatbot to learn; the AI lives right in the compose window.

​
Caption rewrite

Write a draft, then let the assistant refine it. In the rewrite panel you pick a tone and how many variations to generate: Each request returns between 1 and 5 variations (3 by default). The rewrite stays in the original language and preserves facts, links, mentions, emojis, and calls to action unless the chosen tone explicitly requires shortening.

​
Post Checker

Before you publish, the Post Checker scores a drafted post per platform on a 0-100 scale across four dimensions:
  • Hook - the first line earns attention
  • Clarity - the message is immediately understandable
  • CTA - a useful next action when one is appropriate
  • Platform fit - length, structure, tone, and formatting suit the target platform
It returns a few concise positives and actionable negatives that cite specific parts of your post. The Post Checker deliberately does not predict views, reach, or engagement; it only scores what is visible in the supplied post.

​
Providers and configuration

The AI can run on OpenAI, DeepSeek, or Gemini:
  • On PostSider Cloud, the platform provider is configured for you and quota-bound by your plan.
  • On a self-hosted instance, the operator either sets AI_API_KEY (or OPENAI_API_KEY) for the whole instance, optionally with AI_PROVIDER (default openai) and AI_MODEL, or an Admin opens /settings/post-checker and saves an organization bring-your-own key with its provider and model. Until a key is available, the rewrite and check actions return an error.
The /settings/post-checker page is not listed in the Settings navigation; open it by URL on self-hosted instances.

​
Usage and quota

In managed billing mode, AI is plan-gated with a monthly action quota: Standard 50, Team 150, Pro 500, and Ultimate 1,000 actions (a new trial includes 10). One action is consumed per rewrite, and one per platform checked. The compose window shows your remaining usage.
