Turn your handwriting into a real fontreal font with Claude

What you need

• A Claude accountThe free plan works. Use claude.ai on the web or the Claude app.
• File creation turned onSettings > Capabilities > Code execution and file creation. It is on by default for most accounts.
• Paper and a dark penPlain white paper and a black or dark blue pen.

How to do it

1. Write your alphabet

   Write A to Z, a to z, 0 to 9 and . , ! ? in rows. Leave about a finger's gap between letters so Claude can cut them out cleanly.

2. Take one clear photo

   Lay the paper flat in daylight, with no shadow on it, and take the photo from straight above.

3. Give Claude the photo and this prompt

   Start a new chat, attach the photo, paste the prompt, and wait a few minutes while Claude works.

   Handwriting to font prompt Copy

   I've attached a photo of my handwriting: A to Z, a to z, 0 to 9 and . , ! ? written in rows on white paper.
   Turn it into a font file I can install.
   Use Python (for example OpenCV, potrace and fontTools) to find each character, trace it as a clean vector outline and build a .ttf.
   Keep the holes in letters like a, b, d, e, o, p, A, B, D, O, P, R.
   Give every letter the same baseline, add natural spacing and a space character, and name the font "My Handwriting".
   Before you give me the file, render a preview of "The quick brown fox jumps over the lazy dog 0123456789" in the new font and check every character.
   Fix any letter that is missing, merged or filled in, then give me the .ttf to download.

4. Fix any letter that comes out wrong

   If a letter looks wrong in the preview, tell Claude which one it is, for example The g is filled in, redo it, and it tries again.

5. Install your font

   Download the .ttf file and double-click it. On a Mac, click Install in Font Book. On Windows, click Install. Then pick My Handwriting in Word, Pages or any app on your computer.

Good to know

Making files uses more of your messages than a normal chat, so on the free plan you may need to wait for your limit to reset if it takes many fixes.

Clear, evenly sized letters give the cleanest font. Messy letters still work, they just look like your messy handwriting.
