## 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

## Muse

Muse is a personal AI agent developed by Meta. Instead of answering questions and stopping there, Muse is designed to carry work through to completion: you hand it a goal or an ordinary task and it plans the steps, uses the tools it needs and reports back. Typical jobs include triaging and sorting email, booking reservations, shopping and saving money, keeping calendars in order, drafting fitness and health plans, and helping you stay on top of the relationships that matter to you.

Under the hood, every Muse user shares a dedicated Secure Virtual Machine with their agent — a persistent, isolated Linux computer running a full browser. This is what lets the agent do genuine work online rather than only talk about it. You can watch what it is doing and step in at any point, since the browser and machine belong to you. Storage, CPU and memory are sized for real workloads, not just demos.

You interact with Muse the way you already communicate: through the Muse app on mobile and desktop, or directly in WhatsApp, by text or voice. Control is explicit rather than implicit. Muse asks for approval before sensitive actions such as sending an email or making a purchase, and it keeps a complete audit trail of everything it has done and everything it is planning to do. It also connects to the apps you use daily — email, calendar, Instagram and more — with you deciding what it can see and what it may do, and it can even build a custom tool when a task needs one that does not exist yet. Muse is positioned for both individuals and small businesses.

**Pricing & Plans:** Muse is listed as contact-for-pricing on our directory; Meta has not published standard public plan pricing on the main product page, and access currently flows through logging in or creating an account. There is also a Muse for Business offering aimed at small businesses. Check the official site for the latest availability and any regional pricing.

- **Agentic task execution:** Give Muse a goal or an everyday chore and it plans and carries out the steps itself rather than only advising you.
- **Secure Virtual Machine:** Each user gets a persistent, isolated Linux computer in the cloud with a full browser, so the agent can do real work online while you retain control.
- **Human approval controls:** Muse requests your approval before important actions such as sending an email or making a purchase, keeping you in the loop.
- **Full audit trail:** A complete record of what the agent has already done and what it is planning next, so its behavior stays transparent.
- **Chat in app or WhatsApp:** Talk to your agent through the Muse mobile and desktop apps or directly inside WhatsApp, using text or voice mode.
- **App connections and custom tools:** Link everyday apps like email, calendar and Instagram, and let Muse build a bespoke tool when a task needs one that doesn't exist.

**Strengths:** Backed by Meta with a dedicated secure virtual machine per user; Approval prompts and a full audit trail keep agent actions accountable; Accessible from mobile, desktop and WhatsApp with text and voice; Can connect daily apps and build custom tools on demand

**Limitations:** Public plan pricing is not clearly published, making cost hard to estimate up front; Availability and feature rollout may vary by region; Agentic automation still benefits from careful review of approved actions
