Tapword Translator
Inline translation browser extension for deep reading
Tapword's inline 'subtitle' translation is a genuinely novel approach that eliminates popup frustration—translations appear under your text like annotations, leaving the page untouched. The BYOK mode gives privacy-conscious readers full control, with requests sent straight to OpenAI, DeepSeek, or Moonshot. It's free, open-source, and works on Chrome, Edge, and Firefox. It lacks full-page translation for now, but for deep reading of foreign-language articles, papers, and docs, it's arguably the best free browser extension we've seen—at least until the page-translation feature ships.

About Tapword Translator
Tapword Translator is a free, open-source browser extension designed for foreign language learners and professionals who need to read deeply online. Instead of popups or sidebars, it displays translations directly below selected text, like subtitles or margin notes, preserving the original page layout. Select a single word to get a dictionary card with phonetics, part of speech, and definitions. Select a longer phrase or sentence and it switches to AI-powered contextual translation using large language models to understand the surrounding context. The extension supports 100+ target languages and offers two translation modes: an official cloud service (no account or registration needed) and a bring-your-own-key mode where translation requests go directly to providers like OpenAI, DeepSeek, or Moonshot, bypassing Tapword's servers for added privacy. It works on Chrome 88+, Edge 88+, and Firefox 90+, with offline CRX installation available. The project is fully open-source, and currently lacks full-page translation, which is marked as 'coming soon'.
Behind the Verdict
Tapword Translator is a purpose-built tool for a specific workflow: reading foreign-language content line by line without the disruption of popups or layout shifts. The core mechanic—embedding translations directly beneath selected text like annotations—feels like reading a bilingual book. For language learners and professionals who need to understand nuance, this is a real advantage over full-page translators like Google Translate (which can break layouts) and popup-based extensions (which cover the original text). Strengths: The selection-based translation is fast and precise. Auto-expand word selection saves you from pixel-perfect highlighting. Single-word lookup gives you rich dictionary data (phonetics, part of speech, definitions) without leaving the page. Sentence translation uses LLMs for context, which handles idioms and ambiguous phrasing far better than traditional dictionaries. The BYOK option is a standout for privacy: your text goes directly to your chosen provider, not through Tapword's servers. And it's completely free, open-source, and works on the three major desktop browsers. Weaknesses: As of now, there's no full-page translation—you can only translate what you select. The 'coming soon' promise has been on the page for a while, so if you need to translate an entire page frequently, this isn't ready. There's no mobile support (it's desktop-only via browser extensions). The official cloud service routes requests through Tapword's servers, so if you're on the free cloud mode, your text passes through their infrastructure (they say they don't store it, but it's still a third party). Where it fits: If you're a student reading academic papers in a second language, a professional scanning technical docs, or a polyglot who wants to read foreign news without friction, this is excellent. It's also great for exam prep when you need to understand grammar and word usage in context. Where it doesn't: If you want one-click page translation, quick skimming, or mobile reading, this isn't the tool. You'll be better served by a full-page translator or a popup-based extension. Overall, for focused deep reading, Tapword is a sharp, well-executed tool that respects the text and the reader.
