How to use Inkstract

Everything you need to turn handwritten notes into structured, searchable Markdown — from your first email to customising your setup.

1. Getting started

Sign up for a free account at inkstract.com. You don't need a credit card.

Once you're in, open your Dashboard. You'll see your personal inbound email address — something like yourname@in.inkstract.com. This is the address you'll send documents to.

Three steps to get going

  1. 1.Sign up and find your inbound address on the Dashboard.
  2. 2.Add that address to your device's contacts or share settings.
  3. 3.Send a PDF — your processed notes will appear in Documents within a minute or two.

Your inbound address is also shown on your Settings page if you ever need to copy it again.

2. Sending documents

Inkstract accepts PDFs sent as email attachments. Any device or app that can export a PDF and email it will work.

reMarkable

Open a notebook, tap the share icon, choose Send a copyEmail, and enter your Inkstract address. reMarkable exports the notebook as a PDF automatically.

Supernote

From the file browser, long-press a note and tap Share → Email, or use the Export option to send as PDF to your Inkstract address.

Boox

Open a notebook, tap the share icon, select Export as PDF, then share to your email app and address it to your Inkstract address.

GoodNotes

Tap the three-dot menu on a notebook, choose Export → PDF, then tap the share icon and email it to your Inkstract address.

Notability

Open a note, tap Share → Export as PDF, then send via your email app to your Inkstract address.

Paper notes (photographed)

Take clear, well-lit photos of your handwritten pages. Use your phone's built-in document scanner (iOS Notes, Android Google Drive, or any scanner app) to convert them to a PDF, then email it to your Inkstract address. Good lighting and a flat surface make a big difference to OCR accuracy.

Any other app

If your note-taking app can export to PDF, it will work. Just email the PDF to your inbound address. You can attach multiple PDFs to a single email and each one will be processed separately.

3. Understanding your output

Once processing is complete, open any document from your Documents list. You'll see two things: a rendered Markdown view of your notes on the left, and a structured sidebar on the right.

The Markdown view

Your handwriting is transcribed and organised into clean Markdown. Headings, lists, and paragraphs are inferred from the layout of your page. You can download the raw Markdown file from the document page if you want to import it into Obsidian, Notion, Logseq, or any other tool.

Tasks, events, and notes

Inkstract recognises bullet journal notation and pulls out structured items:

  • Open tasks appear as checkboxes
  • Completed tasks are shown as checked
  • Events are extracted to the Events tab
  • Notes appear in the Notes tab
  • >Migrated items are tracked separately

These are all shown in the sidebar so you can scan them quickly without reading the full document.

Diagrams and sketches

Non-text content — diagrams, drawings, doodles, flow charts — is extracted and preserved as images. They're embedded inline in your Markdown output at the position they appeared on the page, so the visual context is maintained.

4. Document titles

Inkstract automatically names your documents based on what it detects in your handwriting — a date, a heading, or a meeting title if one is present.

You can change the title at any time by clicking the pencil icon next to the document name on the document detail page. The original filename is preserved underneath for reference.

5. Todoist integration

Connect your Todoist account in Settings to have extracted tasks automatically pushed to your Todoist inbox. Connect once and it works on every document you send.

Tasks include due dates if you've written them — phrases like by Friday or next Wednesday are picked up and attached to the task automatically.

You can disconnect the integration at any time from the same Settings page.

6. Email delivery

Turn on Email me when processing completes in Settings and your processed notes will be delivered straight to your inbox as a formatted email with diagrams inline. A copy of the raw Markdown file is attached.

No need to log into the dashboard — your notes come to you.

7. Your dictionary

Your personal dictionary teaches Inkstract the vocabulary you use — abbreviations, acronyms, project names, people's names, technical jargon. The more entries you add, the more accurate your transcriptions will be.

Adding entries

Go to Dictionary and add any abbreviation or shorthand you use. Each entry has:

  • Abbreviation — what you write (e.g. QBR)
  • Expansion — what it means (e.g. Quarterly Business Review)
  • Description — optional context to help with interpretation

Replace inline vs. context only

Replace inline

The abbreviation is substituted with its full expansion in your Markdown output. Useful for acronyms you want spelled out — e.g. NPS becomes Net Promoter Score.

Context only

The expansion is used to help the OCR and AI understand what you wrote, but the abbreviation stays as-is in your output. Good for names or terms where you want to keep the shorthand — e.g. JB stays as JB but the system knows it means Jamie Briggs.

Auto-detected abbreviations

When Inkstract encounters a token it doesn't recognise — a short all-caps sequence, an unusual word, something that looks like an abbreviation — it flags it for your review. These appear in your Dictionary under the Review queue. You can confirm them (adding them to your dictionary with an expansion you supply) or dismiss them. Over time this teaches Inkstract your specific vocabulary without any manual work.

8. Bullet journal notation

Inkstract is built around Ryder Carroll's Bullet Journal system. It recognises the following symbols by default:

Symbol Meaning
Note
Task (open)
Task (complete)
> Task migrated forward
< Task scheduled
Event
Sub-note / supporting detail
! Priority / important
Inspiration / idea worth keeping

Customising symbols

If you use a different notation system, or want to add extra symbols, go to SettingsBullet journal symbols. You can override any default symbol or add new ones using JSON:

{"#": "topic tag", "~": "in progress", "?": "needs follow-up"}

Your custom symbols are merged with the defaults, so you only need to specify the ones you want to change.

9. Privacy & security

Your notes are personal. Inkstract is built with privacy as a constraint, not an afterthought.

  • All content — transcriptions, dictionary entries, your Markdown output — is encrypted at rest with a key unique to your account.
  • Source PDFs are deleted immediately after processing by default. You can change this in SettingsSource file retention to keep originals for 24 hours, 7 days, 30 days, or indefinitely. When a source file is still available, you'll see a View Original PDF link on the document page.
  • API calls to OCR and AI services are made without your identifying information.
  • You can export all your data at any time from Settings → Export.
  • You can delete your account and all data permanently from Settings → Delete account.
  • You can report abuse or any concerns about how the service is being used here.

For the full details, read the Privacy page.

10. Tips for best results

Write clearly. This sounds obvious, but consistent letter shapes and a comfortable writing speed make a bigger difference than anything else. Rushed notes with ambiguous letterforms are the main cause of OCR errors.

One topic per page works better than dense pages. When a page covers multiple subjects, the AI has a harder time inferring structure. If you're a heavy note-taker, consider separating topics with a clear heading or starting a new page.

Keep diagrams visually separate from text. Inkstract extracts non-text regions as images. If diagrams and handwriting are tightly intermixed, the extraction boundary is harder to determine. A clear border or blank space between text and diagrams helps.

Add your abbreviations early. The dictionary has the biggest impact on accuracy for jargon-heavy notes. Five minutes adding your most common abbreviations before your first important meeting will save you a lot of manual corrections.

Review the auto-detect queue. When Inkstract spots something unfamiliar, it adds it to your dictionary review queue. Checking this after your first few documents quickly builds up a dictionary tailored to your vocabulary.

Use the email subject line. The subject of the email you send becomes the document title in Inkstract. Something like Team meeting 2026-03-13 is easier to find later than notebook-export.pdf.
