The workflow is deliberately minimal — paste code into the input panel, press Convert, and read the typed output beside it. Because everything runs in the browser session, the maintainers state that submitted code is processed in real time and not stored or logged. Beyond the headline JS-to-TS converter, the site has grown into a fairly broad developer utility collection. Around it sit sibling tools such as JSON to TypeScript, OpenAPI to TypeScript, TypeScript to Zod, TypeScript to JavaScript, JSX to TSX, CSS to Tailwind and back, plus a family of data-format converters (YAML, XML, CSV, TOML-adjacent formats) and small helpers like a JWT decoder, Base64 encoder and regex tester. There are also reference cheatsheets and comparison guides for TypeScript, Zod and Tailwind, which makes the site useful as a documentation-adjacent resource rather than only a one-shot converter. The tool positions itself against manual migration: renaming .js files to .ts and typing every parameter by hand. It advertises handling of function signatures, object shapes, array and tuple types, unions, generics, class properties, async/Promise returns, module export types and React component props, and it falls back to any or unknown when a type genuinely cannot be inferred. It is a general-purpose web app rather than an IDE extension, so the practical usage pattern is copy-in, convert, copy-out. **Pricing & Plans:** Completely free with no account, login or credit card. The site is supported by sponsors and ads, and advertises unlimited conversions. - **AI JavaScript to TypeScript conversion:** Paste JavaScript and receive TypeScript with type annotations, interfaces and generics added automatically, including function parameters, return types and class properties. - **Framework-aware output:** Handles React component code and hooks as well as Node.js modules, with JSX rewritten for TSX-style typing. - **Broad converter catalogue:** Companion tools cover JSON to TypeScript, OpenAPI to TypeScript, TypeScript to Zod, TypeScript to JavaScript, JSX to TSX, CSS to Tailwind and dozens of data-format conversions. - **No signup, no storage claims:** Conversions run immediately without an account; the site states code is processed in real time and never stored or logged. - **Learning resources:** TypeScript, Zod and Tailwind cheatsheets plus comparison guides help you understand the types the converter produces. **Strengths:** Genuinely free with no login wall or usage cap advertised; Handles the tedious parts of migration — parameter, return and property typing; Large companion converter library makes it a convenient one-stop utility site; Offers safe fallbacks (any/unknown) instead of silently inventing incorrect types **Limitations:** AI inference is not a compiler: complex or ambiguous code still needs manual review; Web-only copy/paste workflow is slower than an IDE plugin for whole repositories; Very large files are best split into sections, which adds friction [Profile (Markdown)](https://openaitools.app/tool/js2ts.md) ## Linux Helper Linux Helper targets the gap between knowing *what* you want a server to do and remembering *how* to express it in Bash. Describing a task such as resizing a volume, auditing open ports, or cleaning up log files in plain language returns a command line you can run, which shortens the lookup loop for infrequent but important administration tasks. Because it runs on iPhone, iPad and Apple-silicon Macs, it is available in the same device you already carry to a rack or use for on-call rotations. A second capability is fault analysis. Instead of only producing commands, the app can take a described symptom and help narrow down where the problem sits, which is useful when an unfamiliar service is misbehaving and you want a starting hypothesis rather than a dictionary definition. The developer also lists a voice keyboard mode for fast, hands-free entry, described as coming soon at the time of writing. The app is distributed as a free download with an optional Pro subscription, listed at $0.99 per month or $9.99 per year on the US App Store. It holds a 4.9 out of 5 rating from a small pool of reviewers and supports English and Simplified Chinese. Generated commands should always be read before execution — especially anything touching disks, permissions or production services — since the model can produce plausible but incorrect syntax. **Pricing & Plans:** Free to download with optional in-app purchases; the app lists Linux Helper Pro at $0.99 per month or $9.99 per year on the US App Store. Confirm current regional prices in the store listing. - **Natural-language command generation:** Describe an administrative goal in everyday language and receive an executable Linux command you can inspect and run in your shell. - **System problem analysis:** Report a symptom and get help tracing it to likely causes, useful for diagnosing unfamiliar services and complex faults. - **Voice keyboard input:** A quick-entry voice keyboard mode, listed by the developer as coming soon, for dictating requests instead of typing them. - **Runs across Apple devices:** One app for iPhone, iPad, Apple-silicon Mac and Apple Vision, with a 20.3 MB footprint and iOS 15.0 or later required. - **Optional Pro subscription:** Unlock the paid tier through in-app purchase at $0.99 monthly or $9.99 yearly, with the base app free to download. **Strengths:** Free to download, with a low-cost Pro tier for heavier use; Available across iPhone, iPad, Apple-silicon Mac and Apple Vision; Covers both command generation and troubleshooting, not just syntax lookup; High 4.9 out of 5 rating from early App Store reviewers **Limitations:** The voice keyboard feature was still listed as coming soon; Generated commands can be subtly wrong, so manual review is essential; Only English and Simplified Chinese are supported [Profile (Markdown)](https://openaitools.app/tool/linux-helper.md) ## Frequently Asked Questions ### How do JS2TS and Linux Helper compare in monthly traffic?
