About OpenViking
The Context Database for AI Agents English / 中文 / 日本語 Website · Live Demo · GitHub · Issues · Docs · Blog Lark · WeChat · Discord · X What is OpenViking OpenViking is an open source context database for AI agents — one filesystem for everything an agent knows: knowledge, memory, and skills. Most agent memory is a black box: text goes in, embeddings come out, and nobody can see what was actually stored. OpenViking organizes context as a virtual filesystem under viking:// instead. Agents navigate it like files — ls , tree , read , write , grep — and you can open any directory to inspect and edit what your agent…

About Agentero
为人与 Agent 协作而生的一站式科研工作台 保留人类舒适的 PDF 阅读习惯，为模型提供纯净的结构化上下文；文献、笔记与交互记录统一沉淀于本地。 中文 English 如果本项目对你有帮助，请在右上角 给个 star 吧！ 背景与设计初衷 Zotero 是学术管理领域非常优秀的软件。它功能成熟、生态稳定，帮助许多科研人员建立了最初的文献归档体系。 但在当下日常科研与深度使用各类 Agent 时，传统的文献工具链暴露出一些断点： 上下文严重分散 ：论文存储在 Zotero，笔记记在 Obsidian，与模型的推导和分析留在各个网页对话框中。三者数据彼此隔离，当需要 Agent 结合某篇具体论文与历史笔记进行深入推导时，用户必须反复手动复制粘贴。 文献格式对模型不友好 ：人类习惯阅读排版良好的 PDF 文件；但对于模型而言，直接解析双栏排版、跨页表格、复杂数学公式和交叉引用的成本极高，极易产生识别错误与幻觉。结构化 Markdown 与 LaTeX 才是模型容易准确理解的格式。 维护成本较高 ：AI 伴读、全文翻译、笔记同步等高频需求，往往需要安装和调试多个社区插件，配置门槛高且在版本升级时容易出现兼容性问题。 批量自动化能力有限 ：通过 Deep Research 或自动化检索工具发现的大量文献，目前仍需人工在浏览器中逐篇点击保存，难以顺畅衔接批量研究流。 Agentero 并非旨在替代…
