# Fact checks and "Why this post"

> What the "Check this" warnings mean, what Social9 checks in AI drafts, and how to read "Why this post".

AI can sound sure of things that are not true. Social9 checks every AI draft against what you told it, and shows you what to look at before it goes out.

## Where you see them

Under AI-written text in **Create**, on every post in **Plan many**, and on AI captions in **Upload**.

## "Check this" warnings

A yellow box lists anything in the draft that Social9 cannot find in your facts sheet or brand profile. For example:

> Check this: $49 isn't in your facts sheet.

| It checks | Examples |
|---|---|
| **Prices** | $49, €12.50, 20 dollars |
| **Percentages** | 20%, 15 percent |
| **Dates** | Oct 20, 20 October, 2026-10-20 |
| **Other numbers** | Anything above 12, like "500 customers". Small counts like "3 tips" are fine |
| **Strong claims** | Words like best, #1, cheapest, guaranteed, award-winning, free delivery, limited time, sold out |

A warning does not stop you from posting. It asks you to look.

**What to do:**

- If it is wrong, fix the text.
- If it is true, add it to your facts sheet in [Brand voice](https://social9.com/docs/brand/brand-voice). The warning goes away, and the AI can use it next time.

> **Note:** Without a facts sheet, Social9 checks against your brand profile instead, and says so.

## "Why this post"

Press **Why this post** under a draft to see where it came from.

| Line | What it tells you |
|---|---|
| **Topic** | Which of your content topics it matches, or "General" if none |
| **Voice** | The voice it was written in. **Edit voice** takes you there |
| **Based on** | The source: your link, your description, or the brand profile |

If posts keep landing on "General", add topics in your brief or brand profile.
