Does Google Tasks support Markdown in notes?

Short answer

No. Google Tasks notes are plain text. Typing Markdown such as `bold`, `# Heading`, or `- [ ] checkbox` does not turn into formatted text in Google’s Tasks apps on iPhone, on the web, or in the Gmail and Calendar side panels.

The details field is still useful. It holds free-form text that travels with the task across devices. It is not a rich document editor.

What the notes field is for

Each task can have a title plus optional notes (sometimes labeled Details). That field is meant for short context:

• A phone number, order ID, or confirmation code
• A one-line agenda for a meeting
• A shopping note you do not want in the title
• Links you can paste as plain URLs

Those notes sync with the Google Tasks backend, so the same text can show in Gmail’s Tasks panel, on Google Calendar when the task is dated, and in any Tasks client signed into that account.

What notes are not for: long-form writing, styled outlines, or embedded images. If you need a full document, keep the task as the reminder and put the write-up in Docs, Keep, or another notes app.

Why Markdown does not appear

Google Tasks is built as a lightweight checklist that sits next to Gmail and Calendar. The public Tasks model is lists, titles, notes, due dates, subtasks, and completion state. There is no rich-text or Markdown rendering layer in that model.

That is why people who paste Markdown from another app see the raw characters later. The syntax is stored as ordinary text. Nothing in stock Tasks parses it into bold, lists, or headings.

This is also different from Google Keep, which is better at capture and reference material, and from Apple Notes or Reminders notes that may feel more document-like on iPhone. Tasks stays intentionally simple so the same row can surface in email and calendar without carrying a full document format.

Practical workarounds on iPhone

If you want structure without leaving Google Tasks as the source of truth:

1. Keep the title short; put structure in plain text. Use line breaks, numbered steps, and clear labels (`Agenda:`, `Bring:`, `Link:`) instead of Markdown markers.
2. Use subtasks for steps. Nested checklist items are a better fit than fake Markdown checkboxes inside notes. See how subtasks work on iPhone.
3. Paste URLs as plain links. You can still open them from the notes field; you do not get Markdown link syntax like `label`.
4. Attach the real file when text is not enough. Stock Google Tasks has no attachment field. If you need a PDF, photo, or local note file on the task itself, a native iPhone client that adds file links is the practical path while titles and notes still sync to Google.

ETasks is that kind of client: two-way Google Tasks sync for lists, titles, notes, due dates, and subtasks, plus file links and cross-list search on iPhone. It does not invent a Google-side Markdown format. Notes remain plain text so they stay compatible with Gmail, Calendar, and Google’s own Tasks apps.

When to use another app instead

Choose a different tool when the work product is the document, not the checklist:

• Long briefs, meeting notes, or research: Docs, Notes, or Keep
• Heavy formatting and databases: Notion or similar
• Gmail and Calendar as home base, with a better iPhone shell for the same Tasks data: a native Google Tasks app such as ETasks

Splitting “write it here, remember it there” is fine when each app has a clear job. The friction starts when you expect Tasks notes to behave like a Markdown editor.

Quick answers

Does Google Tasks support Markdown? No. Notes are plain text with no Markdown rendering.

Will `bold` or `# heading` format in Tasks? No. Those characters stay visible as typed.

Can I put checklists in a task? Use subtasks for real checklist rows. Markdown checkbox syntax in notes will not become interactive items.

Does ETasks add Markdown to Google Tasks? No. ETasks keeps notes as plain text for Google sync, and adds iPhone-side help such as file links and search across titles and notes.

Where should long formatted text live? In a notes or docs app, with a short Google Tasks item pointing at it by title, URL, or attached file link.
