The examples
Handwritten letters, cards, and envelopes
A letter, a card, a postcard, an envelope — real files straight from HandTextAI Business, exactly as they print. The handwriting varies naturally in letter shapes, spacing, and alignment.
Mail merge
Handwritten mail merge from CSV or Excel
Upload CSV or Excel — every row becomes its own handwritten card. Placeholders pull from any column, so whole sentences change from row to row, not just the name.
01The template — write it once
Hi first_name, Thank you for choosing us for your service in city this month. technician told me everything went smoothly — if anything ever needs a second look, one call and we're there. — Dana, Harbor & Pine Home Services
02Your spreadsheet — every row a recipient
A spreadsheet, customers.xlsx, with columns first_name, service, city, month, and technician. Row one: Emma, roof repair, Portland, June, Cole. Row two: Priya, gutter replacement, Salem, July, Alex. Row three: Marcus, chimney inspection, Bend, August, Sofia. Row four: Ava, deck refinishing, Eugene, September, Noah. Row five: Daniel, fence repair, Corvallis, October, Maya. Each row becomes its own handwritten card.
03Every row — its own card

Frequently asked questions
Handwriting generator questions
What is HandTextAI Business?
HandTextAI Business is an online handwriting generator and API for business letters, cards, postcards, and envelopes. Convert typed text into realistic handwriting, personalize it from a spreadsheet, and download print-ready PDF, PNG, or SVG files. You print and mail the files yourself.
Do you print and mail the letters?
HandTextAI Business creates the files. You download your letters, cards, postcards, and envelopes, then print and mail them on your printer, through a print shop, or through your existing mailing service.
What files can I download?
Download PDF and PNG files for printing, or SVG files for pen plotters. Each document uses the paper size you choose, including US Letter and A4 for letters, 5×7 cards, and #10 envelopes.
How does the handwriting generator create natural variation?
Handwriting fonts provide the letter shapes. The generator varies their appearance, spacing, and alignment as it renders each document. You can preview the result before downloading it.
Is there a text to handwriting API?
Yes. The handwriting API creates letters, cards, postcards, and envelopes with the same rendering as the dashboard. It also supports templates, recipient lists, and mail merge. Read the handwriting API documentation →
Can I use CSV or Excel for handwritten mail merge?
Yes. Upload a CSV or Excel spreadsheet and write one message with placeholders. Every row becomes a personalized letter, card, or postcard. Fields can insert names, addresses, or whole sentences, and each row can include an addressed envelope.
How do I create personalized handwritten letters?
Choose a letter, card, postcard, or envelope, write your message, and select its handwriting and layout. For a mailing list, upload your spreadsheet and insert fields from its columns. Preview the documents, generate your files, and download them for printing.
Can I use the files with a pen plotter?
Yes. Download your handwritten letter, card, postcard, or envelope as SVG and open it in your pen plotter software. The plotter draws the handwriting with a real pen.
How much does it cost?
Credit packs start at $20 for 100 credits. One credit creates one letter page or card; an envelope uses half a credit and a postcard uses one and a half credits. The price per letter page ranges from 20¢ in the starter pack to 10¢ in the 10,000-credit pack. Custom credit amounts are available in your account. No subscription. See all credit packs →
