Use the result as a reference and revise if needed

The result shows an overall risk label, points that may concern readers, wording tips, next actions, and a pre-post checklist. Risk labels are shown with gentle explanations, such as low risk, medium risk, and high risk. The displayed risk level is a guide to how the wording may be received, including the possibility of misunderstanding or negative reactions. It does not indicate whether the information is accurate or current, the likelihood that it is misinformation, or the AI’s confidence. “Tips for checking information” appears immediately after the pre-post checklist. Action buttons for editing while viewing the result and copying the current text are shown near the result and again below these tips.

From the second check onward, a risk change banner shows how the latest result compares with the previous check. This makes it easier to see whether your revisions helped reduce the wording risk.

Use the result as a calm reference before posting. Click Edit while viewing result if you want to revise your text.

A self-checklist is also shown. The current screen places Tips for checking information after it, followed by the edit and copy buttons.

When revising the text while reviewing the verification results, make the edits in the editing area displayed at the bottom of the results.
Clicking the "Re-check revised text" button allows you to review the text again after the revisions.

Tips for checking information

“Tips for checking information” is an optional self-check that helps you review sources, dates, scope, updates, and other details before sharing information online.

It does not use AI to determine whether information is true or false. It is intended to provide a brief pause before sharing so that you can review the information yourself.

How to use it

1. Open Tips for checking information in the result.
2. Review the items that relate to what you plan to post or share.
3. Select items when helpful.
4. If anything needs another look, check the original source and the latest official information.
5. Revise your wording if needed.

The checklist is optional. Please use only the items relevant to what you are sharing. Your selections do not affect the AI writing check result or the displayed risk level. You do not need to select every item.

Six checklist items

1. I checked the original source and supporting evidence.

   Check whether the information can be traced to an original announcement, post, document, dataset, or other supporting material. If you provide a source separately, consider whether readers can access and review it.

2. I checked relevant primary sources from public authorities.

   Where relevant, check official information from the government body, ministry, local authority, or other public institution responsible for the topic. Also confirm that a website or account claiming to represent a public authority is an official source.

3. I checked the date, location, scope, and any updates.

   Check when and where the information applies, who or what it concerns, and whether it is still applicable. Also check for any updates, corrections, withdrawals, or follow-up announcements.

4. I separated facts, inferences, opinions, and second-hand information.

   Check whether information presented as fact, your own inferences or opinions, and information received from others are clearly distinguished. When something has not been confirmed, wording that makes this clear can reduce misunderstanding.

5. Where appropriate, I checked another independent source.

   For important or high-impact information, consider checking another independent source rather than relying on a single post or one person’s account. Check whether the other source has its own basis and is not simply repeating the same information.

6. I checked the source and supporting context of images, videos, and charts.

   Check the original post or material, when and where it was captured or created, and what it represents. Consider whether it may have been cropped, edited, reused from another event, or generated using AI. For charts and graphs, also review the axes, sample size, scope, and time period.

What this feature does not do

This feature does not:

• determine whether information is true, false, or misinformation;
• retrieve or verify content from websites or social media posts;

• guarantee that information is accurate or still applicable.

Important information

Do not rely on this checklist alone when making decisions involving disasters, health, legal matters, safety, or public procedures.

Please check reliable primary sources, including the latest official information from the relevant public authority. In an emergency, follow guidance issued by the appropriate authorities.

Open a social media service if you want to post

After reviewing your text, you can choose a service and click Open. The tool only opens the selected service. It does not post your text automatically.
If you click Open LINE, the LINE talk screen opens only in environments where the LINE app is installed. Otherwise, the LINE app download page may open.

Choose a service from the list.

Select the service you want to open.

• Opening a service does not automatically post your text.
• Supported destinations include X, Threads, Instagram, Facebook, TikTok, LINE, LinkedIn, and YouTube.

Example: opening X

If you choose X and click Open, the X posting screen opens. You can then decide whether to paste and post your text yourself.

The tool opens X, but it does not post automatically.
