How it’s done.

Ask your assistant.

• Connect it once. Add our connector to Claude, ChatGPT or Grok, or any assistant that speaks MCP, and sign in. It runs in your own assistant account.
• Ask in plain words. It reads your brand from your website, starts the letter, writes the words, picks a look and adds the people, from a spreadsheet or one of your lists.
• A letter for each person. Tell it what you know about each person and it writes every one a letter of their own, sized to fit.
• Nothing goes without you. It shows you the words, who they’re to and the price first, with a link to see it in the app. It only orders when you say yes, from credits you already have; card payments stay with you, in the app.

Meet Nib.

• Our own handwriting model. Nib doesn’t choose the words. It draws yours as pen strokes, the way a hand moves, so the writing never comes from a font.
• Twelve hands. Choose one of twelve styles, then how neat it is, from loose to neat.
• Drawn for each person. Every letter is drawn for its own words, the name and the details included, rather than copied from one master.
• See it before you pay. In the app you see every person’s letter in Nib’s own strokes, exactly as the pen will write it.

Written by robots. Unquestionably human.

Real fountain pens, real ink, real paper. Just a steadier hand than ours.

• A real fountain pen. Our robots hold a real fountain pen and write every letter out stroke by stroke, along the lines Nib drew.
• Real ink. Wet ink from a real nib, not print. It sinks into the paper, the way a pen’s does.
• Real paper. Every letter is on high-quality paper you choose, at no extra cost.
• Then into the post. We seal it in its envelope, stamp it and post it, first or second class, or box them up and send them to you.
