Accessibility Features

Pluto is designed to be accessible to all users. We follow web accessibility standards and continuously work to improve the experience for everyone. If you find any accessibility issues, please get in touch!

Here is an overview of the accessibility features of Pluto:

Keyboard Navigation and Shortcuts

Pluto is fully usable without a mouse. You can navigate and control everything using only your keyboard:

  • Keyboard shortcuts: Execute cells, navigate between cells, and access common functions quickly. You can find a list of all our shortcuts here
  • Tab navigation: Move through all interactive elements on the page using the Tab key
  • Code editor navigation: Special tab handling inside code cells lets you indent code with Tab while still being able to navigate out of the editor with keyboard-only controls. This video shows an example:

Pluto also supports touch-only use with your device’s on-screen keyboard (OSK): the virtual keyboard that appears on your screen when you tap a text field on tablets, touchscreen laptops, or any device without a physical keyboard.

This makes Pluto accessible for users who rely on keyboard-only navigation, whether due to motor disabilities, personal preference, or assistive technology requirements.

Visual Accessibility

High Contrast Text

We design almost everything with enough visual contrast in light and dark mode. This way:

  • All text meets WCAG 2.0 Level AA contrast standards (minimum ratio of 4.5:1)
  • Ensures readability for users with low vision or color blindness

Dark Mode Support

  • Pluto automatically follows your operating system or browser’s light/dark mode preference
  • No manual switching needed, it adapts to your system settings

Font Size and Zoom

  • Use your browser’s zoom function (Ctrl/Cmd + ±) to adjust the size of Pluto’s interface
  • Your zoom preference automatically saves between sessions
  • Text and UI elements scale proportionally for consistent readability

Reduced Motion

  • Pluto respects the prefers-reduced-motion CSS setting. If you’ve enabled “Reduce motion” or “Prefers reduced motion” in your browser or OS accessibility settings, Pluto will minimize animations
  • Helps users with vestibular disorders or motion sensitivity

Screen Reader Support

Pluto uses semantic HTML and ARIA (Accessible Rich Internet Applications) labels to work with popular screen readers including JAWS, NVDA, VoiceOver, TalkBack, and Narrator. We follow WAI-ARIA best practices to ensure interactive elements are properly announced and navigable. Current screen reader experience:

  • HTML exports are very screen reader friendly
  • Live notebook editing has basic screen reader support, but we’re actively working to improve this experience

We need your feedback! If you use a screen reader with Pluto, please share your experience - what works well and what could be better. Your input is essential for helping us prioritize improvements. See this issue to join the conversation or use our feedback tool to report accessibility barriers.

Language Support

Pluto is available in multiple languages, making it accessible to non-English speakers. You can:

  • Switch languages at the bottom of each notebook
  • Contribute translations to help make Pluto available in your language

You can read more on about it in this section.
