Browser extension that flips Deepseek chat for right-to-left users
RTL for Deepseek, developed by diako hamidian, adapts the Deepseek AI chat interface so right-to-left languages display naturally. The extension flips conversation direction for Persian, Arabic, and Hebrew users, applying changes directly in the browser without a full page reload. It provides a visual toolbar control and remembers the last choice across sessions. The add-on targets individual users and web developers who need readable RTL chat sessions and quick compatibility checks.
It implements in-place direction changes inside the browser
The extension integrates into the browser to change document direction without forcing a page refresh, so conversational text reflows immediately. It is built as a Firefox add-on and is compatible with Manifest V2 and V3 extension models, which matters for deployment on modern desktop Firefox builds. In-place adjustments reduce interruption during active chat sessions and avoid losing transient prompts or generated responses.
It preserves technical text by excluding code blocks from mirroring
The tool deliberately leaves code regions in left-to-right order, keeping programming syntax intact while the rest of the interface mirrors. That behavior supports Persian, Arabic, and Hebrew workflows listed by the developer, and keeps stack traces and snippets readable during debugging or code review inside the chat. Selective mirroring prevents accidental inversion of identifiers, strings, and punctuation used in code.
It offers immediate controls and low-configuration testing for developers
The extension exposes a one-click toggle and a toolbar icon that reflects the current state, plus persistent settings that apply on return visits. Those elements let QA engineers and front-end developers toggle direction quickly while validating UI alignment. The developer maintains the project on GitHub and publishes a Chromium-based counterpart, which helps cross-browser testing workflows despite this release being packaged for Firefox.
Its scope and reception suit targeted use rather than wide localization audits
The add-on is deliberately focused on a single chat domain and a narrow user problem, a design that keeps it lightweight and simple to use. It has received a positive rating on the Firefox Add-ons store from its niche audience, reflecting that focus. For broader localization audits across many domains or automated cross-site validation, a site-agnostic RTL test harness is a better fit.
A practical, narrowly focused tool for RTL chat readability
The extension is a practical choice for individuals and small teams who need readable right-to-left conversations inside a specific AI chat service; it delivers that value with minimal setup. The trade-off is its narrow scope, which makes it less appropriate for cross-site localization testing or enterprise-wide RTL validation. Choose it when Deepseek chat is the primary target and quick, low-overhead fixes are required.
