## Cursor

Cursor began as an AI-first code editor and has grown into a broader development platform centered on agents. The desktop application gives you the usual editing, navigation, and debugging experience, but every step is wrapped with AI assistance: context-aware completions, natural language edits, and repository-wide questions answered from an indexed understanding of your project.

Beyond single-file help, Cursor runs autonomous agents that take a described task and work through it end to end. Agents can read documentation, search the codebase, edit many files, run terminal commands, and prepare a summary of what changed. Cloud agents take this further by running in their own hosted environments so long tasks continue even when your laptop is closed, and CLI plus Slack and GitHub integrations let the same agents operate where your team already works.

Model choice is a first-class feature rather than a fixed decision. Cursor lets you switch between leading models from several providers depending on whether you want deep reasoning, low latency, or cheap bulk edits, and teams get enterprise controls for security and governance. It is used by individual developers and large engineering organizations alike.

**Pricing & Plans:** Cursor follows a freemium model: there is a free tier with limited usage plus paid individual and team plans, and separate enterprise pricing that requires contacting sales. Exact rates are best confirmed on the official pricing page.

- **Autonomous coding agents:** Hand off a task in plain language and agents plan it, edit across multiple files, run commands, and report back what changed.
- **Cloud agents and parallelism:** Launch several agents at once in hosted environments so long-running work continues in the background while you focus elsewhere.
- **Flexible frontier model access:** Choose between models from multiple leading providers per task, balancing reasoning depth, speed, and cost as needed.
- **Works where your team works:** Cursor runs as a desktop IDE, in the terminal via CLI, and inside Slack and GitHub so agents review pull requests in existing workflows.
- **Codebase-aware context:** Indexed repository understanding and semantic search give suggestions and agents awareness of your actual project structure and conventions.

**Strengths:** Deep, context-aware assistance that understands an entire repository rather than single snippets; Agent workflows that can genuinely complete multi-step coding tasks end to end; Freedom to switch between many frontier models instead of being locked to one; Usable across desktop, terminal, Slack, and GitHub with cloud agents for long tasks

**Limitations:** Heavy agent usage consumes plan allowance quickly, so costs can scale with intensity; The breadth of features takes time to learn and configure well; Most advanced agentic capability depends on a paid plan

## DiffDuo

DiffDuo is a lightweight diff checker that runs entirely client-side. 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
