Inspiration

I have an art company, sometimes, customers just throw an image, then tell us to draw using that font for text. I had hard time to search for similar font, or even couldn't do it. Sometimes I wish I just threw an image and got the font and then can continue to do the work.

What it does

Generate font from text or image using codex oauth.

How we built it

Asked Codex to research and write documentation explaining what it takes to create a font, what knowledge is needed to build a font-making app, and everything else that would help me understand the process and prompt AI more effectively.
Then created a document called Vision based on the original idea.
Asked Codex to write an Architecture document based on the research and Vision documents.
Get prompt guides for GPT-5.6 and Fable, then asked Codex to use those guides, along with the project documentation, to create the AGENTS.md and CLAUDE.md files.
After that, caffolded the project based on the architecture and set up a proper logging system so AI tools can debug issues more easily.
I asked Claude and Fable 5 to run workflows and implement everything described in the documentation.

Results after two workflow runs

Workflow 1: The app worked, but the UI was too complicated and felt more suitable for advanced editing.
Workflow 2: The UI was much simpler and closer to the original idea. It could also reuse the output from the first workflow as an advanced editing mode.

The main work left is refining the details, making font exports faster, and improving the app’s output quality. Codex can probably be used to handle those improvements.

Challenges we ran into

Generate images, need consistency between characters, also speed.

Accomplishments that we're proud of

Hmm, turned out the idea works. This project is a byproduct of pi workflow development. I'm developing workflow + subagents for pi to use 5.6 Sol in pi (Codex consumed my limit so fast). And it is developed during OpenAI dev day, I thought we can only dev a product on this time period.

The more interesting thing's I posted the demo on my Facebook, a few people ordered it at the price $19. lol
