Plain Markdown

Terms of Service

Last updated: August 8, 2026

Summary

These terms cover your use of the Plain Markdown browser extension and the optional Premium license. The free extension runs in your browser and converts pages locally. Premium is a one-time purchase that unlocks AI actions, which run through an AI provider key you supply. By using the extension or buying Premium, you agree to these terms.

What you get

Plain Markdown is a Chrome extension that converts webpages into clean Markdown. Conversion runs locally on your device and is free, along with the editor, multi-tab capture, and sending to destinations such as Obsidian, Readwise, and Notion.

Premium is an optional one-time license that unlocks AI actions. You supply your own API key from an AI provider and choose the model; that provider bills your usage, not us. Premium is delivered as a license key emailed at checkout, and no account or login is required. Your license is personal and may not be resold, shared, or transferred.

You can try Premium free for 14 days from the extension settings. The trial starts with an email address, takes no payment method, and does not renew or turn into a purchase. You still need your own AI provider key to run actions during it.

Acceptable use

You agree not to:

  • Use Plain Markdown to generate or distribute content that is illegal or infringes someone else's rights.
  • Resell, sublicense, or share your license key.
  • Probe the service for security vulnerabilities, attempt to access private networks, or interfere with normal operation.

We may suspend or revoke access for clear breaches, such as license-key resale or sharing. Where reasonable, we will let you know what the issue is and give you a chance to fix it first.

Premium and billing

Premium is a one-time payment of $24.99, processed by Stripe. Displayed prices are tax-inclusive where applicable. The license does not expire and does not renew, so there is no subscription to cancel.

A license key works on up to 5 devices. You can reset your devices at any time by getting a fresh key at plainmarkdown.com/my-key.

AI usage is billed directly by your AI provider under your own account. We do not see or invoice that usage.

AI actions

An AI action sends the page content you choose to your AI provider using the API key you supplied, and returns the generated output to you. The request goes directly from your browser to that provider. Output is produced automatically, may be inaccurate or incomplete, and is not a substitute for your own judgment or professional advice. Verify anything important before relying on it.

Privacy and destinations

How we handle your data is described in our Privacy Policy. When you connect an external service as a destination (Obsidian, Readwise, Notion), captured Markdown is sent directly from your browser to that service, which operates under its own terms and privacy policy.

Disclaimers and liability

Plain Markdown is provided "as is" and "as available", without warranty of any kind. We do not guarantee that the service will be uninterrupted, error-free, or fit for any particular purpose, and we may change or discontinue features over time.

If we permanently discontinue Plain Markdown, we will give reasonable notice.

To the fullest extent permitted by law, our total liability to you for any claim related to Plain Markdown is limited to the amount you paid us. We are not liable for indirect, incidental, or consequential damages. Nothing in these terms limits liability that cannot be limited under applicable law.

Changes

If we change these terms in a way that affects you, we will notify Premium customers by email. The date above reflects the most recent change. Continuing to use the service after a change means you accept the updated terms.

Governing law

These terms are governed by the laws of Croatia. Nothing in these terms affects mandatory consumer protections that apply to you under the laws of your country of residence, including the EU and UK 14-day right to withdraw from a purchase.
