Wraps Microsoft's Bing AI web chat service in an Electron container (Chromium renderer + Node.js runtime) to provide native desktop access without browser dependencies. Uses a preload script to inject UI modifications and establish IPC bridges between the main process and renderer, enabling system-level integration while preserving the original Bing chat functionality and conversation tones (Creative, Balanced, Precise).
Unique: Uses Electron's preload script pattern to inject UI modifications and IPC bridges without forking Bing's codebase, enabling lightweight wrapping that preserves upstream functionality while adding desktop-specific features like window management and keyboard shortcuts
vs alternatives: Lighter and more maintainable than browser extensions (no extension API constraints) and simpler than building a custom Bing API client (leverages Bing's existing web interface rather than reverse-engineering APIs)
Exports active Bing chat conversations to Markdown, PNG, and PDF formats through a preload script that captures DOM state and delegates rendering to platform-specific handlers. The system intercepts conversation data from the Bing interface, serializes it into structured formats, and uses native rendering engines (headless Chrome for PDF, canvas for PNG) to produce publication-ready outputs without requiring external dependencies.
Unique: Captures conversation state directly from Bing's DOM via preload script injection rather than requiring API access, enabling export without Bing API credentials; uses platform-native rendering (Chromium for PDF, canvas for PNG) to avoid external library dependencies
vs alternatives: More flexible than browser extension exports (supports multiple formats natively) and simpler than building a Bing API client (no reverse-engineering required); tightly integrated with Electron's native file dialogs for seamless UX
Provides a keyboard shortcut (Ctrl/Cmd + I) that programmatically focuses the Bing chat input textarea, allowing users to start typing immediately without clicking. The preload script injects a listener for this shortcut that queries the DOM for the textarea element and calls its focus() method, ensuring the cursor is positioned correctly for immediate input. This enables rapid context switching from other applications back to BingGPT.
Unique: Uses a simple DOM query and focus() call injected via preload script to enable keyboard-driven focus management without requiring Bing API integration or complex event handling
vs alternatives: More discoverable than hidden focus shortcuts (documented in README) and more reliable than browser-based focus management (executes in preload context with guaranteed DOM access)
Implements a keyboard shortcut (Ctrl/Cmd + N) that creates a new conversation by injecting a click event on Bing's native 'New Topic' or 'New Chat' button through the preload script. The system detects the button element in the DOM and triggers a synthetic click, clearing the current conversation and starting a fresh chat session. This allows users to reset the conversation context without navigating menus or reloading the page.
Unique: Injects a synthetic click on Bing's native New Topic button via preload script, leveraging Bing's existing conversation reset mechanism without requiring API access or custom session management
vs alternatives: More discoverable than hidden shortcuts (documented in README) and simpler than implementing custom conversation management (reuses Bing's native mechanism)
Implements a global keyboard shortcut registry in the main process that intercepts OS-level key events and dispatches them to renderer process handlers via IPC. Shortcuts are mapped to specific actions (new topic, tone switching, response stopping, font size adjustment) with platform-specific modifiers (Ctrl on Windows/Linux, Cmd on macOS). The system uses Electron's globalShortcut API to register shortcuts at the OS level, ensuring they work even when the application window is not focused.
Unique: Uses Electron's globalShortcut API to register OS-level shortcuts that work even when the window is unfocused, combined with IPC dispatch to renderer handlers, enabling seamless keyboard-driven workflows without requiring focus management
vs alternatives: More reliable than web-based shortcuts (OS-level registration vs browser event capture) and more discoverable than hidden keyboard combos (documented in README with platform-specific modifiers)
Manages window state and visual appearance through the main process using Electron's BrowserWindow API, with persistent settings stored in the application's config directory. Supports theme selection (light/dark), font size adjustment (via CSS injection through preload script), always-on-top window mode, and window geometry persistence across restarts. Settings are serialized to JSON and restored on application launch, enabling consistent user experience across sessions.
Unique: Combines Electron's BrowserWindow API for OS-level window control with preload script CSS injection for appearance customization, enabling unified theme and font management without requiring Bing interface modifications or external CSS frameworks
vs alternatives: More persistent than browser-based customization (settings survive application restarts) and more flexible than OS-level accessibility settings (application-specific without affecting other programs)
Establishes bidirectional IPC channels between the Electron renderer process (Bing web interface) and main process using Electron's ipcRenderer and ipcMain APIs. The preload script exposes a safe API surface that allows the renderer to invoke main process handlers for system-level operations (window management, file I/O, keyboard shortcuts) without direct access to Node.js APIs. Messages are serialized as JSON and routed through named channels, with error handling and response callbacks for async operations.
Unique: Uses Electron's preload script pattern to expose a curated API surface to the renderer, preventing direct Node.js access while enabling safe system integration; implements context isolation to prevent renderer code from accessing main process internals
vs alternatives: More secure than exposing Node.js APIs directly to the renderer (prevents privilege escalation) and more flexible than hardcoded main process handlers (enables dynamic command dispatch via named channels)
Manages application startup, shutdown, and window lifecycle through Electron's app and BrowserWindow APIs in the main process. Handles window creation with preload script injection, system tray integration, application quit events, and graceful shutdown. The main process maintains a reference to the BrowserWindow instance and coordinates with the renderer process for state synchronization before closing, ensuring no data loss during application termination.
Unique: Implements standard Electron lifecycle patterns (app.on('ready'), app.on('window-all-closed')) with preload script injection and IPC bridge setup, enabling clean separation between main and renderer processes while maintaining state synchronization
vs alternatives: More robust than web-based chat (native OS integration, proper window management) and simpler than building a custom Electron framework (uses standard Electron patterns without custom abstractions)

Crawls 11+ heterogeneous platforms (Zhihu, Weibo, Bilibili, Twitter, Reddit, HackerNews, etc.) and RSS feeds using platform-specific scrapers, normalizes disparate data schemas into a unified NewsItem model, and deduplicates content across sources using fuzzy title matching and URL canonicalization. The system maintains platform-specific metadata (rank, heat value, engagement metrics) while presenting a single normalized feed, enabling cross-platform trend detection that would be invisible within individual platform silos.
Unique: Implements platform-specific crawler modules with unified NewsItem schema and fuzzy deduplication across 11+ heterogeneous sources (Chinese + international), rather than relying on single-platform APIs or generic RSS parsing. Maintains platform-specific metadata (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) for weighted hotspot scoring.
vs alternatives: Covers more platforms (especially Chinese social media) with deeper metadata extraction than generic RSS aggregators, and provides unified deduplication across sources unlike single-platform monitoring tools.
Implements a multi-stage filtering pipeline that matches news items against user-defined keywords using regex patterns, required word lists, and excluded word lists. The system applies frequency-based scoring (keyword occurrence count) combined with platform hotspot weights to rank filtered results. Configuration is stored in frequency_words.txt with support for regex patterns, AND/OR/NOT boolean operators, and per-keyword weighting. Filtering occurs at collection time (reducing storage) and again at report generation time (enabling dynamic reconfiguration without re-crawling).
Unique: Combines regex pattern matching with frequency-based scoring and platform hotspot weighting (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) in a two-stage pipeline (collection-time and report-time filtering). Supports dynamic reconfiguration without re-crawling by applying filters at report generation.
TrendRadar scores higher at 58/100 vs BingGPT at 34/100.

vs alternatives: More flexible than simple keyword matching (supports regex and boolean logic) and more efficient than semantic filtering (no LLM overhead), making it suitable for real-time filtering at scale.
Detects newly emerged topics by comparing current crawl results against historical data stored in the system. Topics are marked as 🆕 (new) if they appear for the first time in the current crawl or if their hotspot rank increased significantly compared to previous crawls. The system tracks topic emergence velocity (how quickly a topic rises in rankings) and flags topics with unusual acceleration. New topic detection is performed at report generation time, enabling dynamic detection without re-crawling. The system maintains a historical hotspot index for comparison.
Unique: Detects new topics by comparing current hotspot rankings against historical data, marking topics with significant rank increases as 🆕. Tracks emergence velocity to distinguish breaking news from sustained trends.
vs alternatives: More efficient than semantic similarity detection (no LLM overhead) and more accurate than simple first-appearance detection (accounts for re-emerging topics), but requires historical baseline data.
Provides a web-based UI for editing TrendRadar configuration files (config.yaml, frequency_words.txt, timeline.yaml) with real-time validation and preview. The editor supports: (1) syntax highlighting for YAML and regex, (2) validation of keyword patterns (regex compilation check), (3) preview of filtered results based on current keyword configuration, (4) drag-and-drop channel configuration, (5) schedule preview (shows next 10 execution times). Changes are validated before saving, preventing configuration errors. The editor is optional; users can edit config files directly.
Unique: Provides web-based configuration editor with real-time validation, regex preview, and schedule visualization. Enables non-technical users to configure TrendRadar without editing YAML files.
vs alternatives: More user-friendly than manual YAML editing and provides validation feedback, but adds operational complexity compared to file-based configuration.
Integrates LiteLLM to provide vendor-agnostic AI analysis and summarization of filtered news items. Users configure their preferred LLM provider (OpenAI, Anthropic, Ollama, local models, etc.) once in config.yaml, and the system automatically routes analysis requests to that provider. The AI analysis capability includes: (1) automated summarization of long articles into key points, (2) sentiment analysis (positive/negative/neutral), (3) trend prediction based on historical patterns, and (4) custom analysis prompts. Analysis results are cached to avoid redundant API calls and can be pushed directly to notification channels.
Unique: Uses LiteLLM abstraction layer to support any LLM provider (OpenAI, Anthropic, Ollama, local models) with single configuration, enabling provider switching without code changes. Caches analysis results to reduce redundant API calls and costs.
vs alternatives: More flexible than hardcoded OpenAI integration (supports any LiteLLM provider) and cheaper than dedicated sentiment analysis APIs (can use local models), but slower than rule-based sentiment analysis.
Leverages LiteLLM to translate news content from source languages (primarily Chinese) to target languages (English, etc.) on-demand. The system detects source language automatically (via langdetect or similar), caches translations to avoid re-translating identical content, and batches translation requests to reduce API calls. Translations are stored alongside original content, enabling bilingual reports and multi-language notification delivery. Translation can be triggered at collection time (all news) or report time (only filtered news).
Unique: Implements provider-agnostic translation via LiteLLM with automatic language detection, content-based caching, and batch request optimization. Stores translations alongside originals for bilingual report generation.
vs alternatives: More flexible than dedicated translation APIs (supports any LiteLLM provider) and cheaper than commercial translation services when using local models, but slower than specialized translation APIs.
Implements a notification abstraction layer supporting 9+ delivery channels (WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc.). Each channel has a provider-specific formatter that converts normalized news items into channel-appropriate messages (e.g., WeChat card format, Telegram markdown, email HTML). The system batches notifications atomically—all news items for a report are sent as a single batch to each channel, ensuring consistency and reducing API calls. Message formatting respects channel constraints (character limits, attachment limits, etc.) and supports templating for customization.
Unique: Implements atomic message batching across 9+ heterogeneous channels with provider-specific formatters and constraint-aware truncation. Single configuration enables simultaneous delivery to WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc. without code changes.
vs alternatives: Supports more channels (especially Chinese platforms like WeWork, Feishu) than generic notification services, and batching reduces API calls and spam compared to per-item notifications.
Exposes TrendRadar's data and analysis capabilities as an MCP server, enabling AI agents and LLM applications to query trends, perform analysis, and generate insights through natural language. The MCP server implements tools for: (1) querying filtered news by keyword/date/platform, (2) retrieving trend statistics and hotspot rankings, (3) running custom analysis on news subsets, (4) generating reports in various formats. Clients (Claude, other LLM agents) can invoke these tools via MCP protocol, enabling conversational exploration of trends without direct database access. The server maintains state across multiple requests, allowing multi-turn conversations about trends.
Unique: Implements full MCP server exposing trend data and analysis tools to LLM agents, enabling conversational queries and multi-turn analysis workflows. Maintains state across requests and supports complex tool invocations (filtering, analysis, report generation).
vs alternatives: Enables conversational access to trends (vs. API-only access) and integrates with LLM agent workflows (vs. standalone tools), but adds operational complexity compared to simple REST APIs.
