Questions & Answers

As answered by people managing Diff Checker and RTLAuto.

What makes your product unique?

RTLAuto's answer:

RTLAuto is focused on real bidirectional Figma workflows, not only text translation or simple mirroring. It helps designers convert interfaces between LTR and RTL while preserving structure, components, Auto Layout behavior, styles, variables, typography, shadows, gradients, spacing, and directional details.

This makes it useful for product teams and design-system teams that need Arabic, Hebrew, Persian, Urdu, or multilingual interface versions without rebuilding layouts manually.

Why should a person choose your product over its competitors?

RTLAuto's answer:

Choose RTLAuto when your goal is to prepare production Figma files for both RTL and LTR markets with less manual cleanup. It is designed around interface direction, design-system consistency, and practical handoff quality.

RTLAuto is especially useful when a file includes Auto Layout, components, directional icons, typography choices, variables, shadows, gradients, padding, strokes, and translated content that all need to remain coherent after conversion.

How would you describe the primary audience of your product?

RTLAuto's answer:

RTLAuto is built for Figma designers and product teams working on bidirectional interfaces. The primary audience includes global brands entering MENA, regional product teams, government digital services, design studios, small businesses, independent Figma designers, UX/UI teams, localization teams, and design-system teams.

It is most relevant when teams need to support Arabic, Hebrew, Persian, Urdu, or mixed-language product experiences while keeping design files structured and reusable.

What's the story behind your product?

RTLAuto's answer:

RTLAuto was built around a recurring design problem: teams often finish a strong LTR product design, then spend significant manual time preparing the RTL version for Arabic, Hebrew, Persian, Urdu, or mixed-language markets.

The product focuses on reducing that repetitive cleanup inside Figma by automating direction-aware layout adaptation, translation support, font handling, directional icons, components, and design-system details.

  • Katakana issue?
    Another interesting point: I copied both my answer and the suggested answer into diffchecker.com, and it said they were the same. Source: almost 3 years ago
  • 16.0.3 Prod Keys finally dumped
    Never knew diffchecker.com was a thing. Thank you so much for making me aware of it <3. Source: about 3 years ago
  • How to convince someone lossless compression is possible?
    In what way did you show the file comparison? Did you use a diff like diffchecker.com ? If someone can see for themselves that every bit of data between two files is exactly the same, and still thinks they are different, IDK how you could get past that. x == x is pretty fundamental. Source: over 3 years ago
  • Advanced Diff Checker?
    How do I find the actual difference between two strings that appear equal to the naked eye? I used multiple tools and some show no differences, but some show differences. I got diffs on diffchecker.com, but it just shows me that they are different, but not how they differ. Is there a better tool for this? Source: over 3 years ago
  • Is there a library that allows to easily do diffchecks between two json?
    I am wondering if there's something that allows you to easily display differences between two json like on diffchecker.com. Is there a library that allows you to easily do that? Source: almost 4 years ago
