Automatically parses research articles to extract citations and builds a directed knowledge graph where nodes represent articles and edges represent citation relationships. The system clusters articles by citation density and topological proximity to surface knowledge dependencies, enabling users to visualize how research papers relate to and build upon each other. This approach differs from keyword-based organization by preserving the semantic structure of academic discourse through explicit citation links rather than term frequency.
Unique: Uses citation topology rather than semantic similarity or keyword matching to organize articles, preserving the explicit dependency structure of academic discourse. The system appears to weight citations by frequency and recency to surface foundational vs. cutting-edge work.
vs alternatives: Differs from Zotero/Mendeley (manual tagging) and semantic search tools (embedding-based) by automatically surfacing citation relationships without requiring user curation or external embedding models, though at the cost of requiring well-formed citations.
Captures video from the user's webcam and applies computer vision pose detection (likely using MediaPipe or TensorFlow.js) to recognize hand and body gestures in real-time, mapping detected poses to interface actions (navigation, selection, etc.). The system runs gesture inference locally in the browser or on-device to minimize latency, though accuracy degrades significantly in low-light conditions, cluttered backgrounds, or when the user is partially occluded. Gesture recognition appears to be pre-trained on common presentation gestures rather than user-calibrated.
Unique: Implements browser-based real-time gesture recognition without requiring external hardware, motion capture suits, or specialized sensors. The system likely uses lightweight pose detection models (MediaPipe Pose or similar) optimized for webcam input rather than depth sensors, making it accessible but less accurate than dedicated motion capture systems.
vs alternatives: More accessible and lower-cost than professional motion capture systems (Vicon, OptiTrack) but significantly less accurate and reliable than hardware-based solutions; comparable to other webcam-based gesture systems (e.g., Kinect, RealSense) but with no documented accuracy benchmarks.
Provides a curated collection of high-quality research articles and knowledge resources organized by topic or domain. The Masterwork Knowledge Store appears to be a pre-built, editorially curated collection that users can browse, add to their personal knowledge maps, or use as a reference. The curation criteria, update frequency, and editorial process are not documented. This feature is available on both Beginner and Advanced tiers.
Unique: Provides editorially curated collections rather than algorithmically ranked results, emphasizing human expertise and quality over scale. This differentiates Qonqur from search-based tools like Google Scholar.
vs alternatives: More curated and trustworthy than algorithmic recommendations but less comprehensive than full-text search; comparable to reading lists in academic textbooks or Stanford Encyclopedia of Philosophy.
Renders the citation graph and article metadata as an interactive visual map (likely a node-link diagram, force-directed graph, or hierarchical layout) that users can explore by clicking, dragging, or gesturing to zoom, pan, and select articles. The visualization appears to encode article relationships spatially, with proximity or edge weight indicating citation strength. Navigation likely includes filtering by topic, author, or date, though specific filtering mechanisms are not documented. The system may highlight unread articles or articles critical to understanding selected papers.
Unique: Combines citation graph topology with interactive spatial visualization, allowing users to explore research relationships through visual proximity rather than keyword search. The system appears to use gesture control as a primary navigation mechanism (zoom, pan via hand gestures) rather than mouse/keyboard, differentiating it from traditional citation management tools.
vs alternatives: More visually intuitive than text-based citation managers (Zotero, Mendeley) but less feature-rich; comparable to academic visualization tools (Connected Papers, Scopus visualization) but with integrated gesture control as a differentiator.
Tracks which articles a user has read, marked as important, or annotated within the knowledge map, and aggregates this into a progress metric or learning path visualization. The system likely maintains a per-user reading history and may suggest next articles to read based on citation relationships and user progress. Progress is visualized as a path through the knowledge graph, highlighting completed vs. unread articles. The mechanism for defining 'progress' (e.g., articles read, time spent, comprehension assessment) is not documented.
Unique: Integrates progress tracking with spatial knowledge maps, allowing users to see their learning journey as a path through a visual graph rather than a linear checklist. The system appears to use citation relationships to infer logical reading order and suggest next steps.
vs alternatives: More visually engaging than text-based progress tracking (Notion, Obsidian) but less sophisticated than AI-driven learning platforms (Duolingo, Coursera) which use spaced repetition and comprehension assessment.
Exposes a Model Context Protocol server that allows external AI agents or LLMs to query the user's knowledge graph, retrieve article metadata, and potentially trigger actions within Qonqur. The MCP server likely implements standard endpoints for listing articles, retrieving article details, querying citation relationships, and possibly updating reading status. This enables AI assistants (e.g., Claude, GPT-4) to access the user's research collection and provide context-aware recommendations or summaries without requiring manual copy-paste of article data.
Unique: Implements MCP server support to enable AI agents to access the knowledge graph as a context source, allowing LLMs to reason over the user's research collection without requiring manual data export. This is a relatively rare integration pattern; most research tools do not expose MCP interfaces.
vs alternatives: More flexible than built-in AI features (e.g., Copilot in VS Code) because it allows any MCP-compatible AI client to access the knowledge graph; less mature than REST APIs because MCP is a newer protocol with smaller ecosystem.
Provides an interactive, gamified onboarding experience that guides new users through core features (uploading articles, exploring the knowledge map, using gesture controls) via a series of guided tasks or challenges. The tutorial likely uses progress bars, achievement badges, or level-based progression to maintain engagement and reduce cognitive load. Specific game mechanics (e.g., points, leaderboards, time limits) are not documented, but the framing suggests a lighter, more approachable onboarding than traditional documentation.
Unique: Uses gamification and interactive tasks to lower the barrier to entry for non-technical users, rather than relying on written documentation or video tutorials. This approach is more engaging but also more resource-intensive to maintain.
vs alternatives: More engaging than traditional documentation (Zotero help docs) but likely less comprehensive; comparable to onboarding in consumer apps (Duolingo, Slack) but applied to academic research tools.
Extends gesture recognition to support multi-screen setups (e.g., presenter view on laptop, slides on projector) and provides a dedicated presentation mode that optimizes the interface for hands-free control. In presentation mode, the system likely hides non-essential UI elements, enlarges gesture targets, and maps gestures to presentation-specific actions (next slide, previous slide, show notes). Multi-screen support requires detecting which screen the user is facing and routing gesture commands to the appropriate display.
Unique: Extends gesture recognition to multi-screen environments, enabling presenters to control content on a projector while viewing notes on a laptop. This requires screen detection and routing logic that is more complex than single-screen gesture control.
vs alternatives: More sophisticated than single-screen gesture control but still less reliable than hardware-based presentation remotes (Logitech Presenter, Apple Remote); unique in combining gesture control with multi-screen support.

Implements a Model Context Protocol server that bridges Perplexity's real-time search API with LLM applications, enabling structured queries that return synthesized answers with source citations. The MCP server translates tool-call requests into Perplexity API calls, handles response parsing, and returns results in a format compatible with Claude, LLaMA, and other MCP-aware LLMs. Uses JSON-RPC 2.0 message framing over stdio/HTTP transports to maintain stateless request-response semantics.
Unique: Exposes Perplexity's proprietary AI-synthesized search as a standardized MCP tool, allowing any MCP-compatible LLM to access real-time web answers without direct API integration — the MCP abstraction layer decouples Perplexity's API contract from the LLM client
vs alternatives: Simpler than building custom Perplexity integrations for each LLM framework because MCP standardizes the tool interface; more current than retrieval-augmented generation with static embeddings because it queries live web data
Registers Perplexity search as a callable tool within the MCP ecosystem by defining a JSON schema that describes input parameters, output format, and tool metadata. The server implements the MCP tools/list and tools/call RPC methods, allowing LLM clients to discover available tools, validate inputs against the schema, and invoke search with type-safe parameters. Uses JSON Schema Draft 7 for parameter validation and supports optional tool hints for LLM routing.
Unique: Implements MCP's standardized tool registration pattern rather than custom function-calling APIs, enabling any MCP-aware LLM to invoke Perplexity without client-specific adapters — the schema-driven approach decouples tool definition from LLM implementation details
vs alternatives: More portable than OpenAI function calling because MCP is LLM-agnostic; more discoverable than hardcoded tool lists because schema-based registration allows dynamic tool enumeration
Qonqur scores higher at 41/100 vs Perplexity at 40/100. However, Perplexity offers a free tier which may be better for getting started.

Implements a stateless MCP server that communicates via JSON-RPC 2.0 messages over stdio (for local integration) or HTTP (for remote access). Each request is independently routed to the appropriate handler (search, tool listing, etc.) without maintaining session state or connection context. The server uses a simple message dispatcher pattern to map RPC method names to handler functions, enabling lightweight deployment as a subprocess or containerized service.
Unique: Uses MCP's standard JSON-RPC 2.0 message framing with dual transport support (stdio and HTTP), allowing the same server code to run as a subprocess or remote service without transport-specific branching — the abstraction is at the message handler level, not the transport layer
vs alternatives: Simpler than REST APIs because JSON-RPC 2.0 provides standardized request/response semantics; more flexible than gRPC because it works over stdio and HTTP without code generation
Manages Perplexity API authentication by accepting an API key at server initialization and injecting it into all outbound Perplexity API requests via HTTP headers. The server handles credential validation (checking for missing or malformed keys) and propagates authentication errors back to the MCP client. Uses environment variables or configuration files to avoid hardcoding secrets in code.
Unique: Centralizes Perplexity API authentication at the MCP server level rather than requiring each client to manage credentials, reducing the attack surface by keeping API keys in a single process — the server acts as a credential broker between LLM clients and Perplexity
vs alternatives: More secure than embedding API keys in client code because credentials are isolated to the server process; simpler than OAuth because Perplexity uses API key authentication
Parses Perplexity API responses to extract synthesized answer text, source URLs, and citation metadata. The parser maps Perplexity's response schema (which may include nested citations, confidence scores, and related queries) into a normalized output format suitable for MCP clients. Handles edge cases like missing citations, malformed URLs, and partial responses from Perplexity.
Unique: Abstracts Perplexity's response schema behind a normalized output format, allowing MCP clients to remain agnostic to Perplexity API changes — the parser acts as a schema adapter layer
vs alternatives: More maintainable than raw API responses because schema changes are handled in one place; more transparent than black-box search because citations are explicitly extracted and returned
Implements error handling for Perplexity API failures (rate limits, timeouts, invalid responses) by catching exceptions, mapping them to MCP error codes, and returning structured error responses to the client. The server implements retry logic with exponential backoff for transient failures and provides fallback responses when Perplexity is unavailable. Error messages include diagnostic information (HTTP status, error code, retry-after headers) to help clients decide whether to retry.
Unique: Implements MCP-compliant error responses with diagnostic metadata (retry-after, error codes) rather than raw API errors, allowing clients to make informed retry decisions — the error abstraction layer decouples Perplexity's error semantics from MCP clients
vs alternatives: More resilient than direct API calls because retry logic is built-in; more informative than generic error messages because diagnostic metadata is included
