Ghost Font
Ghost Font is a font experiment against AI recognition. It writes text into videos using moving dot matrices, which are readable to the human eye but, according to the official website, hard to restore by mainstream models. Screenshots cannot leak the content, and local previewing and exporting are available.

What is Ghost Font?
Ghost Font is an experimental project launched by Mixfont. Its official website describes it as "An anti-AI font that can be read by humans but not leading AI models". When you input a sentence, it converts the content into a video in the form of moving dot matrices, which is readable to the human eye but, according to the official website, difficult for mainstream AI models to restore. It is not a traditional font file but uses a combination of motion, video, noise and decoy information to convey text.
Who is it for?
- Researchers and content security practitioners who want to verify whether AI can understand a certain visual encoding.
- People who need to post a single sentence on a public page but don't want it to be directly scraped by crawlers and AI models.
- Designers and developers interested in font and visual encoding experiments.
- Technical teams conducting evaluations of anti-crawling and anti-automated content recognition solutions.
Key features
7Dynamic Dot Matrix Writing
The official website states that it combines motion, video, noise, and decoy information to render text into dynamic dot matrices. When paused, the text blurs into a mess, and single-frame screenshots fail to reveal the content.
Local Real-time Preview
The official website states that it runs locally, allowing real-time preview as you type, and you can also download the generated video for sharing.
Adjustable Parameters
The page provides controls such as speed, color inversion, and pause, allowing you to adjust the movement mode as needed.
Limited Length
The input box has a character limit, making it suitable for short sentences rather than long texts.
Screenshot Resistance
The official website states that screenshots will not leak content because static frames cannot restore motion information.
Adversarial Testing
The official website shows the results of testing the generated videos with multiple cutting-edge models. The models read hidden decoy text instead of the real content.
Local Execution
The official website states that the generation process is completed locally, and the input content will not be uploaded to any server.
How to use Ghost Font
- 1Use it only as an experimental and verification tool, not for information that requires long-term confidentiality, as the official website itself states that it is a conceptual prototype.
- 2To have the recipient see the content, directly send the downloaded video file; screenshots or conversion to static images will fail to convey it.
- 3Adjust the speed parameter while balancing readability; the faster the speed, the harder it is for the human eye to perceive, and the slower it is, the more susceptible it is to frame-by-frame analysis.
- 4Conclusions regarding model capability comparisons should be based on current actual tests, as model iterations are rapid.
- 5Before commercial use and secondary development, check the license statement on the official website, which also provides font generation and recognition APIs.
- 6Its readability is significantly lower than that of regular text. Use it only when absolutely necessary, and first consider whether the recipient can read it smoothly.
