Abstracts multiple LLM providers (OpenAI, Anthropic, Google Gemini, DeepSeek, SiliconFlow, Zhipu AI) through a unified service layer that handles model configuration, API credential management, and request routing. The system maintains a model registry with provider-specific parameters and implements adapter patterns for each provider's API contract, allowing users to swap models without changing optimization logic. All API calls execute client-side with credentials stored locally in IndexedDB, eliminating intermediate server dependencies.
Unique: Pure client-side provider abstraction with no intermediate server — credentials stored locally in IndexedDB and requests routed directly to provider APIs from browser/desktop, combined with unified adapter pattern supporting 7+ LLM providers without code duplication
vs alternatives: Eliminates vendor lock-in and credential exposure compared to cloud-based prompt optimizers by executing all provider integrations client-side with local credential storage
Implements a template system that defines optimization workflows as reusable patterns with placeholder variables. The system automatically extracts variables from user input using regex and semantic analysis, then applies templates through a substitution engine that generates optimized prompts by filling placeholders with extracted values. Templates are stored as configuration objects with metadata (name, description, category) and can be customized per-user or shared across workspaces. Variable extraction uses both pattern matching and LLM-assisted detection to identify dynamic content.
Unique: Combines regex-based pattern matching with LLM-assisted semantic variable detection to automatically extract dynamic content from unstructured prompts, then applies substitution through a template engine that preserves formatting and context
vs alternatives: Automates variable detection that competitors require manual specification for, reducing setup time and enabling template generation from existing prompts without explicit variable annotation
Implements comprehensive internationalization (i18n) across all platforms with support for English, Chinese (Simplified and Traditional), and other languages. The system uses Vue.js i18n plugin with locale-specific message files, supports dynamic language switching without page reload, and maintains language preference in local storage. UI components are designed to handle variable-length text across languages, and all user-facing strings are externalized from code.
Unique: Implements comprehensive i18n with Vue.js i18n plugin supporting dynamic language switching and locale-specific message files, with language preference persisted in local storage across all platforms
vs alternatives: Provides native multi-language support across all platforms (web, extension, desktop) that many competitors only offer in web versions, enabling truly international team collaboration
Implements a VCR (Video Cassette Recorder) testing system that records and replays HTTP interactions with LLM provider APIs, enabling deterministic testing without live API calls. The system captures request/response pairs during test execution, stores them as YAML cassettes, and replays them in subsequent test runs. This approach eliminates API rate limiting issues, reduces test latency from seconds to milliseconds, and enables testing without valid API credentials. Cassettes are version-controlled alongside test code for reproducibility.
Unique: Implements VCR-based testing infrastructure that records and replays LLM provider API interactions as YAML cassettes, enabling fast deterministic tests without live API calls or credential exposure in CI/CD pipelines
vs alternatives: Provides deterministic API testing that eliminates rate limiting and credential exposure issues, compared to competitors using live API calls or generic mocking that doesn't capture real provider behavior
Provides containerized deployment through Docker with environment variable configuration for API credentials, model settings, and feature flags. The system includes Docker Compose configuration for local development and production-ready Dockerfile for container registry deployment. Vercel deployment is configured through vercel.json with automatic builds and deployments on git push. Environment variables are externalized from code, enabling secure credential management across deployment environments without code changes.
Unique: Provides Docker containerization with environment-based configuration and Vercel serverless deployment, enabling flexible deployment across infrastructure types without code changes
vs alternatives: Supports both containerized and serverless deployment options that competitors typically specialize in one or the other, providing flexibility for different infrastructure requirements
Implements application state management using Pinia (Vue.js state management library) with reactive stores for prompts, models, templates, and user preferences. The system persists state to IndexedDB on every change, enabling automatic recovery on page reload or application restart. Pinia stores provide centralized state access across all components, with computed properties for derived state and actions for state mutations. Session state includes active workspace, selected models, and UI preferences.
Unique: Implements Pinia-based state management with automatic IndexedDB persistence on every state mutation, enabling seamless session recovery and reactive UI updates without manual save operations
vs alternatives: Provides automatic state persistence that competitors require manual save operations for, combined with Pinia's reactive state management that simplifies component logic
Enables users to export prompts, templates, and workspace configurations in JSON format and import from external sources with format validation. The system implements schema validation to ensure imported data matches expected structure, performs data migration for version compatibility, and provides detailed error reporting for invalid imports. Export includes full metadata (timestamps, optimization history, evaluation results), and import can merge with existing data or replace it entirely. Supports batch import/export for multiple workspaces.
Unique: Implements JSON-based import/export with schema validation, data migration for version compatibility, and batch processing capability for multiple workspaces, enabling data portability without external tools
vs alternatives: Provides built-in data portability that competitors often restrict to premium tiers, enabling users to maintain control of their prompt data and migrate between tools
Enables users to conduct multi-turn conversations with multiple LLM models simultaneously, displaying responses in a multi-column layout for direct comparison. The system maintains conversation history per model, tracks token usage and latency metrics, and allows users to branch conversations at any turn. Each model maintains independent state and context windows, with the UI rendering responses in synchronized columns to highlight differences in reasoning, tone, and accuracy. History is persisted locally in IndexedDB with full conversation replay capability.
Unique: Implements synchronized multi-column conversation rendering with independent state management per model, allowing users to branch conversations at any turn and compare reasoning patterns across models in real-time without server-side conversation coordination
vs alternatives: Enables true side-by-side multi-model conversation testing with branching capability that cloud-based competitors don't offer, while maintaining full conversation history locally without external storage dependencies

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 prompt-optimizer at 37/100.

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.
