## ima.copilot

ima.copilot is an AI knowledge manager from Tencent that treats your own material as the center of the workflow. Instead of a plain chat box, it is organized around knowledge bases: you add documents, web pages, notes, or other files, and the assistant answers questions grounded in that collection. A parallel full-network Q&A mode lets you search and reason over web results when your own library does not have the answer.

The tool follows a 'search, read, write' loop. You search across the web and your library, read and annotate sources, then ask the assistant to help with summaries, notes, reports, presentations, or longer drafts. Outputs draw on the context you have already accumulated, which is what makes it feel more like a working knowledge environment than a generic chatbot.

ima.copilot is distributed primarily as a desktop application, with companion access on mobile and a login-based web entry point. Knowledge bases and conversation history sync through a Tencent account, so the same workspace follows you between devices. Because the product ships as a client rather than a purely browser-based service, checking the official site for current platform availability is the reliable way to confirm what is supported today.

**Pricing & Plans:** ima.copilot is free to start with a Tencent account; paid capacity tiers and storage limits exist inside the client and are shown on the official site. Check ima.qq.com for current plan details rather than relying on third-party summaries.

- **Knowledge bases:** Build personal and shared knowledge bases from documents, web pages, and notes, then question them with context-aware AI answers.
- **Full-network Q&A:** Ask questions against web-wide results when your own library does not cover the topic, with citations back to sources.
- **Search-read-write workflow:** Move from finding material to reading, annotating, and drafting output in a single connected workspace.
- **Content generation:** Turn accumulated knowledge into summaries, reports, presentations, and podcasts without leaving the assistant.
- **Cross-device sync:** Desktop and mobile clients share conversation history and knowledge bases through a Tencent account.

**Strengths:** Backed by Tencent with mature desktop and mobile clients; Knowledge bases keep answers grounded in your own documents; Combines web search, document reading, and writing in one place; Syncs history and libraries across devices

**Limitations:** Primary experience is a desktop client rather than a full browser app; Plan limits and storage tiers require checking the official site; Documentation and interface are optimized first for Chinese-speaking users

## OpenCrab

OpenCrab is built around a simple idea: knowledge should be structured as a graph before agents reason over it. You feed the platform documents, URLs, notes or code, and it handles the unglamorous work of parsing, OCR and chunking. From there it extracts entities, concepts, evidence, relationships and claims, weaving them into a source-attributed ontology graph.

The second half of the product is reuse. Graphs can be saved as versioned ontology packs, shared with teammates, or published and sold through the marketplace. A researcher can turn a stack of papers into a queryable, citation-backed graph; a domain expert can package their know-how as a sellable pack; an AI builder can wire the graph into an agent as long-term memory.

The connector layer is what ties it together. A single MCP server means Claude, ChatGPT, Cursor, Codex and other clients all see the same graph, so grounded retrieval travels with you across tools rather than being locked in one workspace. Pricing starts free, with paid tiers for private ingestion and pack publishing.

**Pricing & Plans:** Free tier at $0/month for exploring and sharing public ontology packs and basic graph queries. Pro is $10/month for private document ingestion and a personal graph RAG workspace. Expert is $30/month for pack publishing workflows and MCP reverse ingest. Billing is handled securely via Paddle and can be changed at any time.

- **Document ingestion and parsing:** Upload documents, URLs, notes or code and let the platform handle parsing, OCR and chunking automatically.
- **Ontology graph construction:** Extract entities, concepts, evidence, relationships and claims into a graph where every node traces back to a source.
- **Reusable ontology packs:** Bundle a graph into a versioned, reusable pack you can share with your team or sell in the marketplace.
- **MCP server integration:** One MCP server lets Claude, ChatGPT, Cursor, Codex and other clients query the same graph.
- **Graph RAG querying:** Retrieve grounded, cited answers from your graph instead of relying on a model's memory alone.

**Strengths:** Turns unstructured documents into a source-attributed graph rather than a flat vector index; MCP server means the same grounded knowledge works across Claude, ChatGPT, Cursor and Codex; Ontology packs are reusable, shareable and sellable, creating value beyond a single project; CRUD-style tiers are affordable, with a genuinely usable free level

**Limitations:** Some features (pack publishing, MCP reverse ingest) are gated behind the Expert tier; Best value requires feeding it well-structured documents; messy inputs limit graph quality; The public library and marketplace are still relatively young, so niche ontologies may be sparse
