It remembers the pages you visit, indexes their content in your own Vectara account, and then lets you ask questions, search by topic or find similar pages. ## 價格與方案 The Sankofa extension is free. It requires a separately created Vectara account, which offers a free tier; usage beyond that tier is governed by Vectara's own pricing. ## 關鍵功能與能力 - **AI research over your history:** Ask ChatGPT-style questions and get answers grounded in the pages you actually read, using Vectara's generative search. - **Remembered page content:** The extension has seen the content of pages you visited, then lets you search those pages by topic instead of by URL. - **Find similar pages:** Point Sankofa at your current page and find other pages in your indexed history that cover similar topics. - **Flexible indexing modes:** Index a page on demand, index only selected text, or let Sankofa automatically index pages after a set delay. - **Powered by your Vectara account:** Connect your own free Vectara account and create a corpus, so all indexed data is stored under your control. ## 主要使用情境 - **Recall what you read weeks ago (Researcher):** Index the sources you read during a project, then ask questions later and get answers drawn from those exact pages. - **Find a page by topic, not URL (Knowledge worker):** Let Sankofa auto-index pages as you browse, then search by topic to find the article you half-remember. - **Discover similar sources you already saw (Student or writer):** Navigate to a page that fits your interest and ask Sankofa for similar pages you previously visited. - **Build a private research corpus (Analyst):** Save only the passages that matter into your corpus and query them as a lightweight second brain. ## 優勢 - Turns ordinary browsing history into a searchable AI knowledge base - Answers are grounded in pages you actually read, not the open web - Works with your own Vectara corpus, so you control the data store - Automatic indexing means research pages save themselves - Free to install with no extension-level subscription ## 限制 - Requires a separate Vectara account and manual corpus setup before it is useful - Indexing relies on your Vectara quota, so heavy browsing can hit limits - Only works meaningfully with a free-but-limited Vectara corpus - Small user base with no update since early 2024 - Content of visited pages leaves your browser to be indexed in the cloud ## 常見問題 ### Do I have to pay to use Sankofa? No. The extension is free, and you connect a free Vectara account, so there is no extension subscription fee. Your Vectara account's own usage limits apply. ### Do I need a Vectara account? Yes. You sign up for a free Vectara account and create a corpus. That corpus is where Sankofa stores the text of the pages you want it to remember and search. ### What data does it access? It stores page content you choose to index in Vectara, and it can read your web history and website content to do so. Data is not sold, but indexed text does live in your Vectara corpus in the cloud. ### How does indexing work? Sankofa can index a single page on demand, index selected text, or automatically index every page you visit after a delay you set. ### Sankofa 的每月流量與成長趨勢為何？ Sankofa 目前每月有 0 次造訪，月流量變化為 +0（成長率 0.0%）。其主要來源市場為全球（佔比 —），其中包含每月 0 次直接造訪與每月 0 次自然搜尋造訪。 ### Sankofa 是免費的嗎？其定價模式為何？ Sankofa 採用免費增值定價模式。The Sankofa extension is free.
