You paste text into the Original and Changed boxes, or drag and drop plain-text files up to 50 MB each, and the tool renders the differences as you type. Removed lines are shown in red, added lines in green, and the specific words or characters that changed are highlighted with a darker background inside modified lines. You can switch between a two-column split view and a single-column unified view that follows the same format as git diff and patch files, with hunk headers such as @@ -12,7 +12,9 @@ and collapsed unchanged regions. Practical comparison controls include ignore whitespace and ignore case toggles, a configurable context setting (3 lines, 10 lines or full file), and a copy-patch button. Long jobs such as files with 100,000+ lines are processed on a background thread so the page stays responsive. The interface is available in a wide range of languages including English, Turkish, Spanish, Portuguese, French, German, Italian, Dutch, Polish, Russian, Ukrainian, Arabic, Hindi, Indonesian, Vietnamese, Japanese, Korean and Simplified Chinese. The tool is intentionally narrow in scope. It is not an AI code review service and does not summarise pull requests; it is a fast, private diff viewer for the moments when you want to see exactly what changed between two blocks of text. DiffDuo is free to use with no sign-up, no account, no cap on the number of comparisons and no advertising. Companion pages cover JSON comparison and list comparison, both of which also run locally in the browser. **Pricing & Plans:** 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. **Strengths:** 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 **Limitations:** 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 [Profile (Markdown)](https://openaitools.app/tool/diffduo.md) ## Macroscope Macroscope targets the review bottleneck that slows most engineering teams down. Every change that lands gets examined for correctness, security, test coverage, and potential regressions, so problems are surfaced during review rather than after a release. Because it understands the wider codebase and not just the diff, its feedback is context-aware, which reduces noisy comments that reviewers tend to ignore. A second pillar is status and visibility. Macroscope reports what changed, why it changed, and what still needs attention across every repository and team, giving engineering leads and product managers a continuous picture without chasing people for updates. It also drafts pull request descriptions automatically, which trims a tedious task that developers often skip. The platform is designed to live inside existing tools rather than replace them. It integrates with version control, chat, and issue-tracking systems such as Slack, Jira, and Linear, so insights arrive where the team already works. Macroscope has also introduced a beta capability, Murmur, which orchestrates cloud agents that write code and verify their work in isolated sandboxes, extending the product from reviewing changes to actively producing them. **Pricing & Plans:** Macroscope offers a free starting point plus paid plans for teams, with an option to book a demo. Because tiers scale by team size and usage, check the official pricing page for current rates. - **AI code review:** Reviews every change for correctness, security, test coverage, and regressions before it lands, using full-codebase context. - **Automated PR descriptions:** Generates clear pull request descriptions so reviewers understand the intent of a change quickly. - **Engineering status updates:** Shows what changed, why it changed, and what needs attention across every repository and team. - **Workflow integrations:** Connects with version control, Slack, Jira, and Linear so insights appear inside tools the team already uses. - **Murmur cloud agents (beta):** Orchestrates agents that write code and verify their work in isolated sandboxes. **Strengths:** Context-aware review that understands the whole codebase, not just the diff; Automatically generated PR descriptions save developer time; Continuous status reporting across repos and teams; Integrates with Git, Slack, Jira, and Linear instead of forcing a new tool **Limitations:** Automated review still benefits from human judgment on nuanced architectural decisions; Advanced capabilities such as cloud agents are in beta; Team-level pricing scales with usage, so costs grow with the organization [Profile (Markdown)](https://openaitools.app/tool/macroscope.md) ## Frequently Asked Questions ### How do DiffDuo and Macroscope compare in monthly traffic?
