API vs web editor
Choose how you want to create your pages
Use the web editor to prepare and adjust individual pages yourself. Request API access if you want to create many personalized pages from a customer list, orders or a shared message template.

FAQ
Questions about API access
Clear answers for direct mail teams, print workflows, postcard products, customer note platforms, and developers evaluating API access.
- What is the Handwriting AI text-to-handwriting API?
- The Handwriting AI API is live for creating handwritten-style cards, letters and other print documents from business data. Access requires an application. We confirm formats, limits and pricing for your project before enabling it.
- How is API access different from the web editor?
- The web editor is best when a person wants to create and adjust a handwritten-style document manually. API access is for business systems that need repeated output from customer data, order data, CSV rows, or application templates.
- Is the text-to-handwriting API available now?
- Yes. The API is live, and access requires an application through this form. Share your use case and expected volume so we can arrange access. Submitting the form does not activate access automatically or add it to a website subscription.
- Can the API create print-ready PDFs?
- For print-ready PDFs, tell us whether you need multi-page documents, higher DPI, bleed, trim marks, or specific file requirements from your print provider. We will confirm which options are available for your workflow when you request access.
- Which page sizes are supported?
- Handwriting AI supports Letter, Legal, Tabloid, A3, A4, A5, A6, B5, 4×6 postcard, and 5×7 greeting card sizes for printing. If you need envelopes or additional card formats, include them in your access request.
- Does batch generation from CSV or templates matter?
- Yes. Batch personalization is one of the main reasons teams request API access. Tell us your template variables, expected row counts, and whether you need ZIP packages or a combined PDF.
- Can I use a custom handwriting font with the API?
- Custom-font API access is planned. Create your font in FontKind AI and use it in the Handwriting AI editor with the same account. Font creation has separate plans and billing. Describe your font and export needs when requesting API access.
- What should I include in my API access request?
- Include your business use case, expected monthly volume, country or region, target output such as postcards or letters, and whether you need PDF, batch generation, custom handwriting fonts, or specific print-provider packaging.
