Its premise is that reading and watching content online is usually passive, so information slips away quickly. Pebble counters that by weaving comprehension checks into the browsing experience: embedded AI questions prompt you to reflect on what you just read, and inline document Q&A lets you interrogate a page's content without opening another tab. Beyond articles, Pebble extends to video. While you watch YouTube, it generates live AI questions that keep you engaged with the material. Everything you highlight, note or answer can be saved to memory, and the extension then turns that material into spaced-repetition and AI quizzes tied to the source website, so review is anchored to where you originally learned it. The extension is published on the Chrome Web Store by a developer operating as "pebble" (contact me@harshpatel.ai), holds a 5.0 rating from a small number of reviewers, and offers in-app purchases for unlocked features. It is lightweight and English-only, with the latest version listed at 1.1, updated in June 2024. **Pricing & Plans:** Free to install from the Chrome Web Store, with optional in-app purchases that unlock the full feature set. - **Active-reading questions:** Embedded AI questions check whether you are genuinely absorbing a page instead of skimming past it. - **Highlights and notes:** Highlight and annotate articles, then keep those notes organized so they are easy to revisit. - **Document Q&A:** Ask questions directly about the page content and get answers in place, deepening comprehension on the spot. - **Live questions on YouTube:** Live AI-generated questions appear while you watch YouTube, turning video into an active-learning exercise. - **Spaced-repetition memory:** Saved questions, highlights and notes become spaced-repetition and AI quizzes to lock in what you learned. **Strengths:** Turns passive reading and watching into active learning; Works across both web articles and YouTube videos; Highlights, notes and Q&A stay anchored to the source page; Spaced-repetition memory and quizzes aid long-term recall **Limitations:** Small install base (about 57 users) and few reviews; In-app purchases are required for the full experience; Last updated in 2024, so feature velocity appears low; Requires a Google account to install and only supports English [Profile (Markdown)](https://openaitools.app/tool/pebble.md) ## Speechify Speechify is a voice AI assistant built around listening, reading and writing with your voice.
