TranslateBuff brings bilingual webpages and model comparison into the browser

Read the translation alongside the source

TranslateBuff is a browser translation extension for Chrome, Edge and Firefox. It offers bilingual and translation-only webpage views, selected-text translation and a comparison hub for trying the same text with several models.

Keeping the original visible can help a reader inspect a technical term or ambiguous phrase instead of replacing the entire page with an answer that is difficult to compare. The product says it uses whole-page context to improve terminology and consistency; that is a vendor claim, not an independent accuracy score.

Match the feature to the reading task

The captured page describes a lightweight popup for highlighted text and an input-field shortcut triggered by pressing the space bar three times. It also lists bilingual YouTube subtitles as a beta feature, with AI sentence segmentation.

The comparison hub sends the same source text through multiple selected models so users can inspect differences in wording and tone. The site advertises more than 20 models and translation engines, including GPT, Gemini, Claude, DeepSeek, Qwen and DeepL. A longer provider list does not by itself establish which result is best for a particular language or document.

For an evaluation, choose a short passage you can check, preserve the original terminology and compare the alternatives. With confidential material, inspect the extension's permissions and the processing arrangements for the selected provider before using a whole-page feature.

Separate the free engines from advanced access

The FAQ describes unlimited webpage translation with Google and Microsoft on the Free plan, together with bilingual reading and selected-text translation. It places advanced AI models and model comparison in Pro.

The captured page does not give a dependable numeric Pro price, so this guide does not invent one. Check the current pricing page, token allowance and provider availability before choosing a plan for long documents or frequent comparison work.
