Spellbox: Code & problem solving assistant

Converts natural language prompts into executable code by capturing the current file context and selected text within VS Code, then sending the prompt to a cloud-based LLM API. The extension integrates via right-click context menu and command palette, automatically injecting the user's code context into the prompt before submission. Responses are inserted directly into the editor at the cursor position or replace selected text.

Analyzes selected code or entire files and generates human-readable explanations by sending the code to a cloud LLM API. The extension captures the selected code block (or current file if no selection), submits it with an implicit 'explain this code' prompt, and returns a natural language explanation that can be inserted as comments or displayed in a panel. Supports 15 programming languages with language-specific explanation patterns.

Stores license keys and email addresses locally in VS Code extension storage after authentication via the 'SpellBox Add License' command. The extension persists credentials to enable automatic re-authentication on subsequent launches without requiring users to re-enter license information. Encryption method and storage location are not documented, creating potential security concerns.

Integrates with Canny (https://spellbox.canny.io/) to collect user feedback, feature requests, and bug reports. Users can submit ideas, vote on existing requests, and track feature status through the Canny portal. This allows the SpellBox team to prioritize development based on community input and provides transparency into the product roadmap.

Offers a complementary standalone desktop application (macOS and Windows) alongside the VS Code extension, providing additional features not available in the extension. The desktop app includes code history and bookmarking capabilities, suggesting a richer feature set for users who want to work outside the editor. The relationship between the extension and desktop app is unclear — unclear if they share the same license or if separate subscriptions are required.

Provides interactive problem-solving by accepting natural language descriptions of programming challenges and generating solutions or debugging suggestions based on the current file context. The extension captures the user's problem statement (via command palette or context menu), combines it with surrounding code context, and returns targeted solutions. Scope of 'problem-solving' is undefined but likely includes debugging, algorithm selection, and architectural guidance.

Implements a freemium licensing model where users authenticate via license key and email address through the 'SpellBox Add License' command. License validation occurs against a cloud backend (https://spellbox.app/licenses-manager), with credentials stored locally in VS Code extension storage (encryption method unknown). Free tier availability and feature restrictions are not documented.

Supports code generation and explanation across 15 programming languages (JavaScript, TypeScript, Python, Java, C++, C#, Go, Rust, Ruby, PHP, Swift, HTML, CSS, MATLAB, Excel) by detecting the current file's language via VS Code's language mode and adapting prompts and output formatting accordingly. Language detection is automatic; no manual language selection is required. The extension indicates 'More coming soon' for additional language support.

Integrates SpellBox actions into VS Code's native right-click context menu, allowing developers to invoke code generation, explanation, and problem-solving without opening the command palette. The context menu appears on right-click in the editor and provides quick access to 'Write code' and 'Explain code' actions. This integration follows VS Code's standard extension context menu API and respects the current selection (selected text is passed as context).

Integrates SpellBox actions into VS Code's command palette (Ctrl/Cmd+Shift+P), allowing developers to search for and invoke SpellBox commands by name. Commands are registered with the VS Code extension API and appear in the command palette with 'SpellBox' prefix. This enables keyboard-driven workflows without requiring right-click or toolbar interaction.

Provides dedicated toolbar icons in the VS Code editor for quick access to SpellBox actions: a caret icon for 'Write code' and a light bulb icon for 'Explain code'. These icons appear in the editor's action bar (typically top-right) and serve as visual shortcuts to the most common actions. Clicking an icon invokes the action with the current selection or cursor position as context.

Implements a freemium business model where users can access SpellBox features without payment (free tier) and upgrade to a paid plan for additional capabilities or higher usage limits. Free tier features and limitations are not publicly documented, but the model allows trial usage before commitment. Paid plans require license key authentication through the license manager portal.

Sends code generation and explanation requests to a cloud-based LLM API hosted at spellbox.app (provider and model name unknown). The extension serializes the user's prompt and code context, transmits them via HTTPS to the API, and receives generated code or explanations in response. All processing occurs server-side; no local model inference is performed. Model selection and configuration are not exposed to users.
