Web2Comics Chrome Extension

The Chrome extension is the browser product in the Web2Comics project.

Product Boundaries

• This document covers the browser extension only.
• Telegram bot behavior, commands, deployment, and bot operations live in separate bot documents.
• Shared comic-generation logic lives in the engine and is referenced here as a common dependency.

What The Extension Does

• Extracts content from the current browser tab
• Lets the user choose providers, models, styles, objectives, and panel count
• Generates a storyboard and panel images
• Shows progress in the popup and rendered output in the side panel
• Saves local history and exports a single composite PNG comic sheet
• Supports right-click selected-text flows for instant generation or prefilled composer flow

Main User Surfaces

• Popup: launcher, create flow, live progress, and popup history
• Side panel: comic viewer, history browser, export/share actions
• Options page: provider setup, prompt templates, storage tools, and diagnostics
• Context menu: selected-text generate and open-composer actions

Provider Model

• Text and image providers are configured separately
• Supported providers include OpenAI, Gemini, Cloudflare Workers AI, OpenRouter, and Hugging Face
• The extension can fall back to other configured providers when a selected provider fails for budget or quota reasons

Data Handling

• Runs locally in the browser extension runtime
• Stores settings, keys, current job state, and history in extension storage
• Sends extracted content and prompts only to the AI providers configured by the user

Shared Engine Relationship

• The extension uses shared engine prompt-building and composition logic from ../engine/
• Engine overview: ./engine.md
• Shared engine code helps keep storyboard and panel-generation behavior aligned across extension and bot products
