readit.dev

Read any web page aloud with 100% on-device TTS. Private, fast, free.

readit.dev is a free Chrome extension that reads web pages, documents, and books aloud with natural on-device Text-to-Speech (TTS). Powered 100% locally by the Supertonic AI engine (WebGPU/WASM), it delivers instant playback and total privacy. ✨ Key Features: • Smart Content Extraction: Automatically extracts article content while stripping away ads, sidebars, and clutter. • Multi-format Document Support: Read web pages, Google Docs, Word Online, PDF documents, Word DOCX files, and EPUB e-books — all with auto-resume, by chapter for EPUB and by page for PDF and DOCX. • Word Online & Google Docs, no sign-in: Open a document on OneDrive, SharePoint, or Google Docs and press Play. The extension reads it through the session your browser tab already has — no extra account connection and no extra permission. • Translate & Read: Hear a foreign-language page in Vietnamese, English, or Chinese. Chrome's built-in translator runs on your device, and the translation opens in the Document Reader with word highlighting and the original text one click away. (Shown only on Chrome versions that include built-in translation.) • Word-level Highlighting: Real-time synchronized highlighting with smart centering and smooth auto-scrolling. • 100% On-device & Private: Runs completely in your browser via WebGPU/WASM. Your text is never sent to any server. • MP3 Audio Export: Export any reading session directly to an MP3 file for offline listening on any device. • Custom Pronunciation Dictionary: Define custom pronunciation rules for acronyms, technical terms, or foreign words. • Playlist Queue: Line up multiple articles or documents for uninterrupted continuous playback. • System Media & Shortcut Controls: Control playback via customizable keyboard shortcuts and hardware media keys (keyboard/headset). • Nostalgic Themes: Choose from modern sleek styles or retro player skins like Winamp and Windows Media Player 12. 📖 How to Use: 1. Read Current Web Page / Article: - Open any web page or article. - Click the readit.dev icon in your toolbar (or use keyboard shortcut) and hit "Play". - To hear it in another language, press "Translate and read" instead. Pick the language under "Translate into" in the Configuration card. 2. Read Selected Text: - Highlight any text on a page. - Click the quick floating button or right-click and select "Read with readit.dev". 3. Read Pasted Text (Manual Reader): - Open the readit.dev Side Panel. - Paste your custom text into the input field and press "Play". 4. Read EPUB, PDF, DOCX, Google Docs & Word Online: - For PDF / DOCX / EPUB: Open the Document Reader from the extension menu/Side Panel and pick a file from your computer. EPUB books chain chapter by chapter; PDF and DOCX step page by page. Whichever you pick, closing the tab keeps your place — reopen and continue where you stopped. (Legacy Word .doc files are not supported; save them as .docx.) - For Google Docs: Open your doc tab and click "Play" to extract and read plain text instantly. - For Word Online: Open a Word document from OneDrive or SharePoint and click "Play". If the document cannot be downloaded — a view-only file, or an expired session — you get a clear message instead of silence. 5. Manage Playlist Queue: - Open Side Panel, click "+ Add current tab" or right-click any link and select "Add to Queue". - Click "Play Queue" for continuous hands-free listening. 6. Export MP3 & Settings: - Export MP3: Click the download/export icon on the player to save audio locally. - Custom Voices & Pronunciation: Open Settings to adjust speech speed, switch voice styles/themes, and configure your custom pronunciation dictionary. 🔒 Privacy First: All speech synthesis and text parsing happen entirely on your local machine. readit.dev never collects, stores, or transmits what you read.
