AutoRAG uses a declarative YAML configuration system that defines a sequence of Node Lines, where each node contains multiple competing modules with different parameter combinations. The Evaluator class orchestrates trials by parsing the YAML config, instantiating all module variants, and systematically testing each combination against evaluation metrics. This enables AutoML-style hyperparameter search across the entire RAG pipeline without code changes.
Unique: Uses a declarative node-line architecture where each node can contain multiple competing modules with independent parameter grids, enabling systematic exploration of RAG pipeline configurations through YAML without code modification. The Evaluator orchestrates all trials and selects winners per node based on configurable strategies.
vs alternatives: Faster than manual RAG tuning because it automates the trial-and-error process across all pipeline stages simultaneously; more flexible than fixed-pipeline tools because each node's best module is selected independently based on your metrics.
AutoRAG implements a modular node architecture where each stage of the RAG pipeline (query expansion, retrieval, reranking, filtering, augmentation, compression, prompt generation) is represented as a distinct Node type. Each node contains multiple module implementations that can be swapped and evaluated independently. The framework uses a NodeLine abstraction to chain these nodes sequentially, enabling evaluation of the full pipeline end-to-end while tracking which module combination produces the best results.
Unique: Implements a typed node architecture where each RAG pipeline stage (retrieval, reranking, filtering, etc.) is a distinct Node class with pluggable module implementations. Modules within a node are evaluated independently, and the best performer is selected per node, enabling fine-grained optimization of each pipeline stage.
vs alternatives: More granular than monolithic RAG frameworks because each pipeline stage can be optimized independently; more structured than ad-hoc evaluation scripts because node types enforce consistent input/output contracts.
AutoRAG's PassageAugmenter node type enables testing of multiple augmentation strategies to enrich retrieved passages with additional context or metadata. Augmentation modules can add related passages, metadata, summaries, or external knowledge to each passage before generation. The framework evaluates which augmentation strategy improves answer quality or reduces hallucination, enabling optimization of context richness.
Unique: Treats passage augmentation as a pluggable node type with multiple competing strategies for enriching passages with context or metadata. Enables empirical evaluation of augmentation impact on answer quality without manual context engineering.
vs alternatives: More flexible than fixed augmentation strategies because multiple approaches can be tested; more transparent than black-box augmentation because augmented passages are visible; enables context-quality trade-off analysis because both metrics are measured.
AutoRAG's PassageCompressor node type enables testing of multiple compression strategies (extractive summarization, abstractive summarization, key-phrase extraction) to reduce passage length while preserving relevant information. Compression modules take passages and return compressed versions, reducing context length and latency while maintaining answer quality. The framework evaluates which compression strategy balances context preservation with efficiency.
Unique: Treats passage compression as a pluggable node type with multiple competing strategies (extractive, abstractive, key-phrase extraction). Enables empirical evaluation of compression impact on answer quality and latency without manual compression tuning.
vs alternatives: More flexible than fixed compression ratios because multiple strategies can be tested; more transparent than black-box compression because compressed passages are visible; enables quality-efficiency trade-off analysis because both metrics are measured.
AutoRAG's Retrieval node type enables testing of multiple retrieval strategies (BM25, semantic search, hybrid retrieval, dense passage retrieval) as distinct modules. Each retrieval module queries the vector database or search index and returns ranked passages. The framework evaluates which retrieval strategy produces the best retrieval F1 or downstream answer quality, enabling optimization of the retrieval stage independent of other pipeline components.
Unique: Implements retrieval as a pluggable node type with multiple competing module implementations (BM25, semantic, hybrid, dense passage retrieval). Enables empirical evaluation of retrieval strategies and their impact on downstream answer quality without code changes.
vs alternatives: More flexible than single-strategy retrieval because multiple strategies can be tested; more transparent than black-box retrieval because retrieved passages and scores are visible; enables strategy-selection based on empirical performance rather than assumptions.
AutoRAG's Evaluator class orchestrates the entire evaluation workflow: loading the YAML configuration, instantiating all module variants, ingesting the corpus into the vector database, executing trials (running each module combination through the full pipeline), computing metrics, and selecting the best module per node. The framework manages trial execution, result storage, and final pipeline selection, enabling fully automated RAG optimization without manual intervention.
Unique: Provides a unified Evaluator class that orchestrates the entire RAG optimization workflow: configuration parsing, module instantiation, corpus ingestion, trial execution, metric computation, and best-module selection. Enables fully automated RAG optimization without manual intervention or custom orchestration code.
vs alternatives: More comprehensive than individual evaluation scripts because it handles the entire workflow; more automated than manual RAG tuning because all steps are orchestrated; more reproducible than ad-hoc evaluations because configuration and results are version-controlled.
AutoRAG provides an API server deployment option that exposes the optimized RAG pipeline as REST endpoints. After evaluation completes and the best pipeline is selected, users can deploy the pipeline as a web service with endpoints for querying. The API server handles request routing, passage retrieval, reranking, generation, and response formatting, enabling production deployment of optimized RAG systems.
Unique: Provides a built-in API server deployment option that exposes the optimized RAG pipeline as REST endpoints without additional code. Handles request routing, pipeline execution, and response formatting automatically.
vs alternatives: Faster to deploy than building custom API wrappers because the server is built-in; more consistent than manual API implementation because the same pipeline logic is used; enables easy integration with external applications via standard HTTP.
AutoRAG provides a web interface for interactive testing and visualization of RAG pipelines. Users can submit queries through the web UI, see retrieved passages, reranked results, and generated answers in real-time. The interface displays pipeline execution details (which modules were used, scores, latencies) and enables debugging of pipeline behavior without code or API calls.
Unique: Provides a built-in web interface for interactive RAG pipeline testing and visualization without additional code. Displays pipeline execution details and intermediate results for debugging and demonstration.
vs alternatives: More accessible than API-based testing because non-technical users can interact with the pipeline; more transparent than black-box systems because intermediate results are visible; enables faster debugging because pipeline behavior is immediately visible.

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 AutoRAG at 37/100. AutoRAG leads on quality, while TrendRadar is stronger on adoption and ecosystem.

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.
