One place to keep your question bank, run a class, and watch what students actually know — instead of guessing from quiz scores. 题库、班级、作业,放在一处。每个学生在练什么、还在哪里出错,不必等到期末考试才发现。
Drop a past paper. Each question becomes a searchable card with image, OCR text, choices, and answer. 拖入一份真题,每道题自动变成可搜索的卡片:题图、文字、选项、答案,都在里头。
Slice the bank by tag, subject, difficulty, or wrong-rate. Build sets for each class without copy-pasting. 按标签、学科、难度、错题率挑题,给不同班级做不同的题集——不用反复复制。
Wrong answers come back tomorrow. Right ones come back later. Students see a tidy review queue, not a wall of problems. 答错了明天还会再见,答对了过几天再说。学生看到的是一份整洁的「今日要复习」,不是一面题墙。
See which questions a whole class fumbles, which student keeps choosing C, which week accuracy dipped. Range-filter to any window you need. 哪道题全班都栽?哪个学生总选 C?哪一周分数掉下来?时间窗口随你切。
Found a great set? Contribute it. Admins review, de-duplicate, publish. Other teachers get a curated library that grows with every contributor. 题集做得好,可以贡献出来。管理员审核去重后入库,其他老师都用得上——题库随着每个贡献者一起生长。
Poppler renders pages, Tesseract OCRs each question, the recogniser splits it into individual cards with choice fields and correct-answer guesses. You confirm or fix, and the set is ready. 系统自动渲染、识别、拆题,把选项和答案预填好。你只需要核对几下,题集就准备好了。
Add subject (physics, math, chemistry…), tags, difficulty. Move questions between sets by drag. Pick a subset for a quiz — the rest stays in your bank. 选学科(物理、数学、化学…)、加标签、标难度。题目拖一下就能在题集之间换位置。挑一部分出来当作业,剩下的留在题库。
Students join with a 6-character class code. Open a set as homework or as free-practice. Set a deadline, time limit, attempts. 学生凭 6 位班级码加入。题集既能当作业发,也能开放给大家自由练。截止时间、答题时长、次数限制都可以设。
Range filter for any window. Top-wrong list. Per-question A/B/C/D distribution. Per-student answer-bias card. Class heatmap. Export when you need to. 想看哪段时间的就看哪段:错得最多的题、A/B/C/D 分布、每个学生的答题偏好、整班的热力图。要导出也行。
Teachers sign in with the account your administrator created. Students join a class with the code their teacher hands out. 老师用管理员给的账号登录。学生用老师发的班级码加入班级,即可开始练习。

StudyFlow is a teacher's tool first. You manage classes, assign work, and read the data. Students see only what concerns them — their score, their progress, their wrong-question list. StudyFlow 首先是一件教师工具。你管班级、布置作业、看数据;学生只看自己的——成绩、进度、错题清单。
A question bank is a habit, not a folder. StudyFlow makes the habit easy. 题库是一个习惯,不是一个文件夹。StudyFlow 让这个习惯轻松起来。§ The product principle产品理念 · 002
