Use Case Recommendations
Best for: Context Link
Context Link gives an AI assistant a single way to query everything a business knows, instead of forcing the operator to pick the right connector or paste the right document into every conversation. You connect your sources once — Google Drive, Notion, files, email, websites, Basecamp, web mentions and custom connections — and Context Link keeps them in sync as one searchable knowledge base. The distinction the product draws is worth stating plainly, because it explains why it exists alongside the first-party connectors: a Notion connector can only search Notion and a Drive connector can only search Drive, whereas Context Link searches everything you have connected in a single pass, by meaning rather than keyword, and returns source-backed answers with citations. It plugs into ChatGPT, Claude, Copilot and Gemini, and ships as a ChatGPT app connector, a Claude skill and a Claude plugin, with two slash commands doing most of the work: /get-context for a longer briefing and /ask-question for a short cited answer. Settled decisions can be saved as Memories under any slash name, so a positioning statement or a pricing rule is written once and then read by every tool that connects. Connections re-sync automatically every twenty-four hours. The higher tier adds Lenses — recurring AI deep research on positioning, competitors and customer support that updates against your live context and tracks how the business shifts over time.
