Coordinates 25+ specialized agents (VideoGenerationAgent, TextToVideoAgent, AudioAgent, SearchAgent, etc.) through a reasoning engine that interprets natural language commands and routes them to appropriate agents based on task decomposition. Each agent inherits from BaseAgent, defines JSON schemas for inputs, implements business logic via run() methods, and communicates status through OutputMessage objects and WebSocket emissions. The reasoning engine (backend/director/core/reasoning.py) handles agent selection, parameter binding, and execution sequencing.
Unique: Uses a specialized reasoning engine (backend/director/core/reasoning.py) that decomposes natural language into agent-specific tasks and binds parameters via JSON schemas, rather than generic LLM function-calling. Each agent is a first-class citizen with defined lifecycle (parameter definition → business logic → status communication), enabling domain-specific optimizations for video operations.
vs alternatives: More specialized for video workflows than generic agent frameworks like LangChain or AutoGen because agents are pre-built for video-specific tasks (generation, editing, dubbing, search) and the reasoning engine understands video domain semantics.
Translates natural language prompts into video generation requests by routing to 18+ integrated AI services (OpenAI, Anthropic, StabilityAI, ElevenLabs, etc.) through a unified tool interface. The VideoGenerationAgent and TextToVideoAgent classes implement provider-specific logic while abstracting differences via a common parameter schema. Requests flow through backend/director/tools/ai_service_tools.py which handles API calls, response parsing, and error handling. Generated videos are automatically stored in VideoDB infrastructure for indexing and retrieval.
Unique: Implements a provider abstraction layer (backend/director/tools/ai_service_tools.py) that normalizes 18+ video generation APIs into a single interface, allowing agents to switch providers without code changes. Generated videos are automatically ingested into VideoDB's native indexing system, enabling immediate semantic search and retrieval without separate ETL steps.
vs alternatives: Broader provider coverage (18+ services) than single-provider tools like Runway or Synthesia, and automatic VideoDB integration eliminates manual video management workflows that other frameworks require.
Provides organizational primitives for managing video collections through VideoDB's collection system. Users can create collections, organize videos by tags/metadata, and perform bulk operations (search, edit, delete) across collections. Collections are persisted in VideoDB and accessible via the API. Supports hierarchical organization (nested collections) and sharing/permission controls.
Unique: Leverages VideoDB's native collection system rather than implementing a separate organizational layer, enabling efficient bulk operations and semantic search across collections.
vs alternatives: More integrated with video infrastructure than generic file organization (folders, tags) because collections are VideoDB-native and support semantic search, not just metadata filtering.
Implements error handling at multiple levels: agent-level try-catch blocks, provider fallback logic, and user-facing error messages. When an agent fails, the system attempts fallback strategies (e.g., use alternative provider, retry with different parameters) before surfacing errors to the user. Error context (stack traces, provider responses, input parameters) is logged for debugging. Partial failures in multi-agent workflows are handled gracefully, allowing subsequent agents to proceed with available data.
Unique: Implements error handling at the agent orchestration level, enabling fallback strategies and partial failure recovery that wouldn't be possible with isolated agent implementations. Errors are tracked with full context (input, provider, retry count) for debugging.
vs alternatives: More sophisticated than basic try-catch because it includes provider fallback, retry logic, and context preservation, but less comprehensive than enterprise error handling frameworks (Sentry, DataDog) which require external services.
Provides a plugin architecture for developers to create custom agents by extending BaseAgent (backend/director/agents/base.py). Custom agents define JSON parameter schemas, implement run() methods, and integrate with the existing tool ecosystem. The framework handles parameter validation, execution lifecycle, status communication, and WebSocket streaming. Documentation and examples guide developers through agent creation, testing, and deployment.
Unique: Provides a standardized BaseAgent interface with built-in support for parameter validation, status communication, and WebSocket streaming, reducing boilerplate for custom agent development. Agents integrate seamlessly with the reasoning engine and tool ecosystem.
vs alternatives: More specialized for video agents than generic agent frameworks (LangChain, AutoGen) because it provides video-specific patterns (frame manipulation, transcription, search) and VideoDB integration out of the box.
Supports asynchronous execution of long-running tasks (video generation, transcription, editing) through a job queue system. Jobs are submitted with parameters, assigned unique IDs, and processed asynchronously by backend workers. Users can poll job status or subscribe to WebSocket updates. Completed jobs are stored with results and metadata. Supports job cancellation, retry on failure, and priority queuing.
Unique: Integrates job queuing directly into the agent execution pipeline, enabling asynchronous processing without separate job management infrastructure. WebSocket subscriptions provide real-time status updates without polling overhead.
vs alternatives: More integrated than generic job queues (Celery, RQ) because it's tailored to video processing workflows and integrates with the agent orchestration system, but less feature-complete than enterprise job schedulers (Airflow, Prefect).
Enables searching video collections using natural language by leveraging VideoDB's native indexing and semantic understanding. The SearchAgent (backend/director/agents/) accepts natural language queries, translates them into VideoDB search parameters, and returns ranked results with relevance scores. Internally uses embeddings-based retrieval (memory-knowledge layer) combined with metadata filtering. Results are streamed back to the frontend via WebSocket with progressive refinement as more results are indexed.
Unique: Integrates VideoDB's native semantic indexing (not external vector databases like Pinecone) for video-specific embeddings that understand visual and audio content, not just text. Search results include precise timestamps and clip boundaries, enabling direct editing or playback without manual scrubbing.
vs alternatives: Tighter integration with video infrastructure than generic RAG frameworks (LangChain + Pinecone) because VideoDB understands video structure (scenes, shots, speakers) natively, producing more contextually relevant results than text-only embeddings.
Processes video audio to generate timestamped transcripts with speaker identification using the TranscriptionAgent (backend/director/agents/transcription.py). Internally routes to external speech-to-text providers (OpenAI Whisper, AssemblyAI, etc.) via the AI service tools layer. Transcripts are stored as metadata in VideoDB, enabling downstream search, dubbing, and content analysis. Supports multiple languages and automatic language detection.
Unique: Transcripts are automatically indexed into VideoDB's semantic search system, making them immediately queryable without separate ETL. Speaker diarization results are linked to video timelines, enabling precise clip extraction by speaker or topic.
vs alternatives: Tighter integration with video infrastructure than standalone transcription services (Rev, Descript) because transcripts are immediately available for search, editing, and downstream agents without manual export/import steps.

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 Director at 39/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
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.
