Log in and pick an API key. The generator uses your iApp account; new accounts can create a key on the API Keys page.
Describe the image. Thai or English, as detailed as you like: subject, setting, style, lighting.
Write the text to render, one line per text. It appears in the typeface you choose, exactly as written. Leave it blank for a picture without text.
Add a real face with @. Type @ in the description to pick from more than 4,000 Thai public figures. At most two people per image.
Optionally upload a reference image. The picture keeps its subject, product or style.
Press Generate and confirm. A dialog shows the description, the people that will get a real face and each text line as a checkbox, so nothing is generated by accident.
Descriptions with sexual content, sexual content involving minors or extreme gore are rejected before generation, and every generated image is screened afterwards. A request that depicts a real person is rejected on any sexual cue at all, including swimwear or underwear. Rejected requests are not charged.
Is it free?
You need an iApp account with credits. Each image costs 1.5 IC during the preview (list price 3 IC). Requests rejected by the content filter are not charged.
What file format are the images?
PNG, returned in the browser and downloadable directly.
Can I use the images commercially?
Yes. Images you generate are yours for personal or commercial use.
How long does it take?
20 to 45 seconds. One pass is about 10 to 15 seconds, and the text check may regenerate up to three times.
Why was my request rejected?
The content filter rejected it. Remove sexual or graphic wording, and do not combine a real person with swimwear, underwear or similar cues.
Ready to Create?
Thai text that is always right, Thai faces by name, in under a minute.
