## Context Link

Context Link connects your docs, websites, inboxes, files, and workspaces into one searchable knowledge base so AI assistants like ChatGPT and Claude can answer with source-backed context. Connect once, then ask across everything.

**Preços e planos:** 7-day free trial. Business plan at $19 per seat per month; Developer API at $50 per month per 10 API user accounts. Cancel anytime.

- **One connected knowledge base:** Notion, Google Drive, websites, email, files, and workspaces kept in sync and searched together in one pass.
- **Source-backed answers:** Every answer cites the exact sources and past lookups are reviewable, so AI responses are verifiable.
- **Memories:** Save settled decisions as reusable memories that every AI tool reads the latest version of.
- **Modes:** Weight connections differently per task, so support leans on help docs and sales leans on pricing and case studies.
- **MCP and API access:** Works in ChatGPT, Claude, Claude Code, and any MCP-aware agent, with a developer API for custom platforms.

**Pontos fortes:** Searches all connected sources in one pass instead of one connector at a time; Semantic search with citations and reviewable lookups builds trust; Memories and Modes add structured, task-specific context; Works directly inside ChatGPT and Claude via MCP

**Limitações:** Pricing is per seat, which adds up for larger teams; Depends on connectors that sync on a 24-hour cycle rather than instantly; Newer product, so the pre-built connection list is still growing

## OpenCrab

OpenCrab is an ontology-centered Graph RAG platform that turns documents, URLs and notes into reusable knowledge packs you can query from any AI client over MCP.

**Preços e planos:** 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.

**Pontos fortes:** 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

**Limitações:** 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
