ZenMulti

Reads JSON and Properties format files from disk, sends raw file contents to OpenAI's API (model version unspecified, likely GPT-3.5 or GPT-4) with implicit translation prompts, and writes translated output back to new or existing files. The extension runs locally in VS Code but delegates all translation computation to OpenAI's remote API, requiring a user-provided API key for authentication. No local translation model, no caching, no translation memory—each file is treated as an independent stateless request.

Accepts multiple JSON and Properties files in a single VS Code session and translates each to unlimited target languages by making sequential or parallel API calls to OpenAI. The extension claims to handle 'unlimited resource files' and 'unlimited languages' but provides no documentation on batch processing strategy (sequential vs parallel), parallelization limits, rate limiting, or error recovery. File size limits are described as 'works well with LARGE files' without specific thresholds.

Enforces a proprietary license key at VS Code extension runtime, requiring users to purchase a $39 one-time license to unlock translation functionality. The license key is validated at extension startup or first use (validation mechanism—online vs offline—is undocumented). No trial period, no free tier for limited translations, and no volume discounts are documented. License is perpetual (no renewal required) and claims to include unlimited updates, files, and languages.

Integrates a 'Open ZenMulti' action into VS Code's right-click context menu for JSON and Properties files, allowing users to invoke translation without leaving the editor. The extension reads the selected file from disk, sends it to OpenAI API, and writes the result back to the file system. No drag-and-drop, no file picker dialogs, no command palette—just right-click and select. Integration is VS Code Extension API-based, likely using the `vscode.commands.registerCommand()` and `vscode.window.showQuickPick()` patterns.

Sends file contents to OpenAI API with an implicit translation prompt (prompt text is not documented or user-configurable). The extension does not expose system prompts, temperature settings, or model selection—it appears to use a hardcoded prompt strategy and a fixed OpenAI model (version unspecified, likely GPT-3.5 or GPT-4 based on marketing claims of 'ChatGPT'). No context injection, no glossary support, no domain-specific instructions—translations are generated based solely on file content and OpenAI's general knowledge.

Reads JSON and Properties files from disk, sends contents to OpenAI for translation, and writes results back to files. The extension claims to handle both formats but provides no documentation on how it preserves file structure, nesting, formatting, comments, or metadata. For JSON: unclear if nested keys are translated recursively, if array values are handled, if formatting/indentation is preserved. For Properties: unclear if comments, key ordering, or escape sequences are preserved. No schema validation or structure-aware parsing is documented.

Requires users to provide their own OpenAI API key for authentication, delegating all API calls to the user's OpenAI account. The extension does not proxy requests through ZenMulti's servers—users pay OpenAI directly for API usage based on token consumption (typically $0.002-$0.06 per 1K tokens depending on model). No cost estimation, no rate limiting, no usage tracking within the extension. API key is stored locally in VS Code settings (encryption method unknown) and transmitted to OpenAI over HTTPS (claimed but not verified).

Writes translated content back to the file system after OpenAI returns translations. The extension either overwrites the original file or creates new files with translated content (strategy is undocumented). No merge strategy, no diff preview, no user confirmation before overwriting. Files are written synchronously or asynchronously (unclear), and error handling for write failures is not documented. No rollback mechanism or version control integration.

Distributes ZenMulti as a VS Code extension available in the official VS Code Marketplace, allowing users to install with a single click without command-line tools, build steps, or configuration files. Installation is one-click, activation is automatic, and setup requires only providing an OpenAI API key and purchasing a license key. No Docker, no npm install, no environment variables—just 'Install' and 'Reload VS Code'. Marketing claims '1 minute no-code setup' but actual setup time includes obtaining OpenAI API key and purchasing license.
