# Skim Recap Skim Recap is a Chrome extension that detects fast scrolling and summarizes the passage you skipped, helping readers recover context without leaving the page. Its summaries run locally in the browser with Gemma 4 E4B through LiteRT-LM. - Findings24: - Site: - Preços: Freemium - Categorias: Ferramentas de resumo com IA ## O que é Skim Recap? Skim Recap is a Chrome extension that helps readers recover context after moving quickly through a web page. It detects a fast scroll, estimates the passage between the previous and current reading positions, and displays a short recap beside the cursor instead of summarizing the whole page. The recap is generated locally in Chrome with Gemma 4 E4B Instruct through LiteRT-LM and WebGPU. The model is downloaded once and cached by the browser for reuse during the session, while the skipped article text is processed on-device rather than sent to a hosted LLM API. The workflow is intended for long articles, documentation, essays, and research posts where readers want to skim without losing the thread. ## O que Skim Recap pode fazer? ### Fast-scroll passage detection The extension monitors scroll velocity and treats scrolling at approximately 1,800 pixels per second as a potential skipped-reading event. After a 180-millisecond settling period, it calculates the distance moved and identifies the relevant passage. ### Passage-bounded recaps Skim Recap extracts text from the range the reader moved past rather than summarizing the entire page. This keeps the recap focused on the context that was skipped. ### On-device Gemma runtime Gemma 4 E4B Instruct runs locally through LiteRT-LM and WebGPU in a Chrome offscreen document. The model is downloaded once, stored with the browser Cache API, and reused across webpage tabs during the browser session. ### Cursor-adjacent reading panel The recap appears near the cursor and streams into the same reading surface. The panel includes local model status, a copy action, a layout control, and a translation action. ### Focus and Smart layouts Focus mode renders the generated recap as a paragraph, while Smart mode presents the same generated text as numbered points. Switching layouts reshapes the existing result and does not run the model again. ### User-requested Feynman explanations Readers can select a phrase on the page or inside the recap card to reveal a Feynman action and request an explanation. This explanation flow is separate from the normal recap and does not run unless the reader asks for it. ## Casos de uso ### Skimming long-form articles Move quickly through a lengthy article and use the recap to restore the context between two reading positions without returning to the earlier paragraphs manually. ### Navigating technical documentation Scan documentation for the relevant section while retaining a compact reminder of a skipped explanation, prerequisite, or transition in the material. ### Reviewing essays and research posts Use passage-specific recaps to follow an argument when reading speed changes, without replacing the source with a summary of the entire page. ### Clarifying unfamiliar terms When a skipped passage or recap refers to a term the page does not define, select the phrase and request a Feynman explanation rather than expecting the bounded recap to add outside context. ## Perguntas frequentes ### What does Skim Recap summarize? It summarizes the text positioned within the passage the reader skipped during a qualifying fast scroll. It does not summarize the entire page. ### Where does the model run? Gemma 4 E4B Instruct runs locally in Chrome through LiteRT-LM and WebGPU, inside a Chrome offscreen document. The site states that skipped article text is not sent to a hosted LLM API. ### How is a recap triggered? The documented trigger uses a scroll velocity of approximately 1,800 pixels per second, followed by a 180-millisecond settling window. The default skipped distance is 1,200 pixels, with an adjustable range of 400 to 3,000 pixels. ### Can the recap define a term that the article never explains? Not through the normal recap, which is intentionally limited to the skipped passage. A reader can select a phrase and use the Feynman action to request a separate explanation. ### Do Focus and Smart modes generate different summaries? No. They use the same generated recap. Focus displays it as a paragraph, while Smart reshapes it into numbered points without regenerating the model output. ## Informações rápidas - **Product type**: Chrome extension - **Primary workflow**: Recap text skipped during fast scrolling - **Model**: Gemma 4 E4B Instruct - **Runtime**: LiteRT-LM with WebGPU - **Processing**: On-device in a Chrome offscreen document - **Default scroll trigger**: Approximately 1,800 px/s velocity; 1,200 px skipped distance
