InkDraft

YOUR IPAD. YOUR HANDWRITING. YOUR NEXT QUESTION.

Think on paper.
Talk it through with
ChatGPT & Claude.

Write a math step, sketch a system, or annotate a PDF. Ask the AI you already use to read it. Make a correction on your iPad and ask again.

Real InkDraft workflow recording showing handwritten control-systems work on an iPad
Real handwriting, earlier interface. Watch the recording below.
01

Write.

Open your document and work with Apple Pencil.

02

Ask.

After sync, ask ChatGPT or Claude to read your work.

03

Correct. Ask again.

Edit your handwriting, wait for sync, and request a fresh read. No new screenshot to upload.

START WITH SOMETHING YOU ARE WORKING ON

A useful second look.

These are example prompts to use with your own document. The assistant supplies the feedback; InkDraft supplies your original pages.

HANDWRITTEN MATH

Find the step that went wrong.

“Read my InkDraft work. Find the first incorrect step and explain why, without finishing the problem for me.”

Keep your equations and notation in view while you work through the reasoning.

DIAGRAMS & SYSTEMS

Talk through the whole picture.

“Explain the blocks and arrows in my InkDraft diagram. Flag anything unclear before making assumptions.”

Discuss the sketch you drew, including its labels and connections.

CORRECTIONS & PDF NOTES

Pick up where you left off.

“I corrected that line. Read my updated InkDraft document and check the change against my notes.”

Annotate a PDF or change your own work, then ask for another read after sync.

REAL WORK. REAL RESPONSE.

Watch a handwritten problem become a conversation.

An existing 72-second demonstration of iPad handwriting and ChatGPT Work feedback. This recording uses an earlier interface. Processing waits are shortened and labeled; it is not a real-time speed benchmark.

BRING THE AI YOU ALREADY USE

One notebook.
Your choice of conversation.

Install InkDraft, open a document, and connect your chosen service using the same InkDraft account. Each service has its own connection and account requirements.

A NOTEBOOK FIRST

Keep your work your own.

Write offline, organize multipage documents in folders, import and annotate PDFs, insert images, and export your work. Local writing, documents, and exports are free.

Connected assistants have read-only access to your current synced document. Opening another document changes what is shared. They cannot edit your ink or browse your local library.

SIMPLE PRICING

$11.99 / year

InkDraft Cloud in the United States. One-week free trial for eligible new subscribers. Cloud sync requires sign-in and Internet access.

ChatGPT and Claude accounts, plans, availability, and limits are separate. InkDraft does not include an AI subscription.

Before your first page.

Does InkDraft automatically ask the AI questions?

No. Your open document syncs automatically. You decide when to ask ChatGPT or Claude to read it and respond. AI feedback can contain mistakes.

Is my whole library backed up online?

No. Only the current document is synced. Folders, inactive documents, and Trash remain on your iPad. Export an editable library backup before deleting or reinstalling the app.

What do I need?

An iPad running iPadOS 18 or later and a compatible Apple Pencil for handwriting. Cloud sharing also requires InkDraft Cloud, Internet access, and an eligible account with your chosen AI service.

How do I manage the subscription?

Payment is charged to your Apple Account. The subscription renews automatically unless canceled at least 24 hours before renewal. Manage or cancel in Apple Account settings. Local writing and exports remain free.
