# Vara(研算) / Vara

> 记录和执行实验的工具，和你常用的 AI 连在一起。
> A tool to record and run your experiments, connected to the AI you already use.

面向做湿实验的科研人员。把实验方案、protocol 或论文方法变成能照着做的步骤,每个参数标明出处,按步骤执行并记录每次运行的结果和偏差。可以在你常用的 AI(Claude / ChatGPT / 豆包 / Cursor 等)里聊完实验,经远程 MCP 连接器存进 Vara;应用内也有助手。Vara 是工具,科学判断由你来做。有网页版和 Mac 版,手机用浏览器打开网页版(可添加到主屏幕)。
For wet-lab researchers. Vara turns an experiment plan, protocol, or paper's methods into steps you can follow, shows the source of every parameter, and records the results and deviations of each run. Plan an experiment in the AI you already use (Claude, ChatGPT, Doubao, Cursor and others) and save it to Vara through the remote MCP connector; there is also an in-app assistant. Vara is a tool: the scientific calls stay with you. Available on the web and as a Mac app; on a phone, open the web app in the browser (you can add it to the home screen).

## 核心能力 / What it does
- 远程 MCP 连接器:在 Claude / ChatGPT / 豆包 / 腾讯 WorkBuddy / Claude Code / Cursor 里读写实验、步骤、运行记录和实验计划,AI 导入的实验先成草稿、由用户核对后建成 / Remote MCP connector: read and write experiments, steps, run logs, and schedules from Claude, ChatGPT, Doubao, Tencent WorkBuddy, Claude Code, or Cursor; experiments imported by the AI arrive as drafts the user confirms
- 导入 protocol / 文献(PDF / 图片 / SOP / 粘贴文字)拆成带参数的可执行步骤 / Import protocols and papers (PDF, image, SOP, pasted text) into parameterized, executable steps
- 参数标出处:AI 提取的每个字段标明确 / 部分 / 推断 / 缺失,用户核对 / Every AI-extracted field is labeled explicit / partial / inferred / missing for the user to check
- 参数引擎:改一个变量,下游依赖步骤确定性自动重算(不靠 AI 猜) / Deterministic parameter engine recalculates dependent steps
- 按步骤执行、计时,记录每次运行的结果与偏差,失败可复盘 / Step-by-step execution with timers, run records with results and deviations, failure review
- 日历订阅:实验计划同步到苹果 / Google / Outlook 日历 / Calendar subscription for the experiment schedule (Apple Calendar, Google, Outlook)
- 免费科研速算器,免登录 / Free bench calculators, no login
- 10 学科差异化复现,内容聚焦生命科学 / 生物 / 化学 / Discipline-specific reproduction across 10 disciplines
