## DiffDuo

DiffDuo is a free online diff checker that compares two texts, files or code snippets directly in your browser. It shows removed lines in red, added lines in green and highlights the exact words that changed, in either a side-by-side split view or a git diff-style unified view.

**料金とプラン:** DiffDuo is completely free: no sign-up, no account, no limit on the number of comparisons and no ads. Comparison runs locally in your browser.

- **Split and unified views:** Read changes in two columns side by side, or switch to a single-column unified diff in the same format as git diff and patch files.
- **Word-level highlighting:** Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ.
- **Local, private processing:** The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device.
- **Whitespace and case tolerance:** Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change.
- **Large-file handling:** Compares plain-text files up to 50 MB in a background thread, so pages with hundreds of thousands of lines do not freeze the UI.

**強み:** Runs fully in the browser, so sensitive text and code are never uploaded; Free with no sign-up, no usage limits and no advertising; Word-level highlighting makes edits inside a line easy to spot; Unified view matches git diff and patch format, including hunk headers

**制約・デメリット:** Limited to plain-text comparison, with no semantic or AI-based code review; No account, saved history or team collaboration features; Requires JavaScript to be enabled in the browser; No desktop or command-line client, so it is a manual copy-and-paste workflow

## Studocu

Studocu is a global study platform where students share and access lecture notes, summaries, study guides and past exams, with an AI assistant, quizzes, flashcards and note tools to help them learn faster.

**料金とプラン:** Studocu uses a freemium model. Signing up and previewing shared documents is free, while unlimited downloads, ad-free browsing and the full AI study toolkit are offered through a paid subscription. You can also earn points by uploading your own study documents and redeem them for premium access, and regional plans and prices vary, so check the official site for current details.

- **Global document library:** Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
- **AI notes and summaries:** Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
- **Quizzes and flashcards:** Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
- **Text-to-speech:** Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
- **Upload and earn points:** Upload your own documents to earn points that can be redeemed for premium download access, alongside the option to subscribe.

**強み:** Huge global library of real student-contributed lecture notes and past exams; AI study tools turn documents into summaries, quizzes and flashcards; Points system rewards uploading your own material and can offset premium costs; Local libraries and multilingual support across many countries

**制約・デメリット:** Full downloads and unlimited access are gated behind a paid subscription; Bot protection temporarily blocks some visitors, which can frustrate access; Quality of user-uploaded study materials varies by course; Some regions may not be fully covered by the local document library
