JS2TS

Free AI converter that turns plain JavaScript into fully typed TypeScript

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.

Strengths & Pros

+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

Cheatsheets and comparison pages give context for the generated output

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

Trae

An AI IDE and coding agent that works on your project, not just your cursor

Project-aware code context

Trae reads your project files and dependencies, so its suggestions account for how the codebase is actually structured rather than treating each file in isolation.

Agentic code generation and edits

Describe a task and the agent plans and applies multi-file edits, shows a diff for review, and can run terminal commands as part of the change.

Debugging and code explanation

Ask questions about unfamiliar code, get inline explanations, and have bugs or failing tests diagnosed and fixed with context.

TraeCode plus TraeWork

TraeCode covers the coding workflow, while TraeWork applies an AI assistant to everyday knowledge tasks — both download for desktop, with a web option.

Strengths & Pros

+Free tier makes it easy to evaluate before paying
+Agentic workflow handles multi-file changes and tests, not just autocomplete
+Deep project context improves the relevance of suggestions
+Covers both coding (TraeCode) and general work (TraeWork)
+Available as a desktop app and in the browser

Limitations

–Heavy usage of premium models quickly hits plan limits
–It is a newer entrant, so some integrations and plugins are still maturing
–Most of the polish is in the coding flow; other workflows are less developed
–Usage-based limits can be confusing to predict for large teams
