Telli.sh: Every Translator

Beside the original, never instead of it

The extension does not overwrite the text you are reading. It adds a second line, and you choose the shape that line takes. The settings page shows a working miniature of each mode before you pick one.

Choose paragraph or whole-message translation. Collapse and reopen results without another request.

• Inline comment

  The translation sits directly under the message, in a quieter weight.

• Bilingual

  Original and translation stacked as a pair, both fully readable.

• Click to expand

  Nothing changes until you click; the translation opens under the line.

• Click to toggle

  One click swaps between original and translation, in place.

• Spotlight

  Highlight a paragraph on hover, select it, then translate only when you press Translate.

Read articles across languages

Medium, Substack, DEV, Cnblogs, SegmentFault, 51CTO, Juejin and CSDN: original paragraphs, headings and translated text together.

Follow the conversation on YouTube

Translate video descriptions and loaded comments without replacing the original. This is not audio dubbing or subtitle translation.

Coverage applies to supported hosts and readable content. Custom domains, sign-in walls and paid content are not unlocked. Each site can be turned off in Settings.

Settings guide

Open the extension toolbar popup to inspect this page’s status, then open Settings to change it. Reading language starts at System; outgoing language at Auto. Display starts at inline comment and translation unit at paragraph. Translation and send preview start on. Context-aware translation starts on for supported LLM engines; this is previous-message context, separate from the web app’s typed Context.

Translate your reply before you send it

Reading is half of a conversation. On supported sites a floating button sits above the composer and opens a panel where your text is translated into the language of the thread — so you read it before it goes out.

Save Clip

Save a link card from one URL and generate an AI summary when useful.

Leave this empty to save only the link and public metadata. Summarizes public description, selected text, or your note when available.

10 translation and AI options

Choose your engine in Settings. Chrome offers on-device translation and conversation modes; local Ollama and cloud APIs are also supported. Page chat, summaries and key points require an engine that supports conversation.

The initial engine is Chrome built-in translation. Availability depends on browser, device and language-pair models; choose a ready engine in Settings. Cloud or compatible providers can need your own key, URL and provider charges. Google fallback starts off. The popup does not prove that an engine is available on your device.

36 sites, grouped the way you would look for them

Inline translation runs on enabled supported sites. Paste text in the popup, or open page chat and choose whether to include the current page.

What leaves the browser, in plain terms

Input assist, instant translation, remote selector updates and opening the side panel on toolbar click start off. Some options request optional site access when you enable them. Review the requested scope yourself. Clip saving needs an explicitly connected token; no token or permission is needed just to read this guide. YouTube support covers descriptions and loaded comments, not dubbing or subtitle translation.
