Use Case Recommendations
Best for: Housecat
Housecat is an email client with an agent workspace behind it, built on the observation that most of the work an email creates happens outside the inbox — updating the CRM, saving the attachment somewhere findable, doing the research the reply depends on, drafting the document that was promised. Housecat's agent has its own cloud workspace and a sandbox VM, so it can carry out that work while you are offline and hand back a result rather than a suggestion. Concretely: it syncs email into your CRM automatically and downloads and files PDFs and attachments; it runs durable email workflows for the back-and-forth-heavy cases — scheduling, intros, event logistics, outbound sales — so the thread converges without you refereeing it; and it creates or updates documents and spreadsheets from inside the inbox, drafting contracts or updating a financial model. The integration that distinguishes it is Claude Skills: you can invoke Claude for help directly in the inbox with no copy-and-paste, using Housecat's template skills or importing your own. It consolidates multiple accounts into one inbox and connects to Google Drive, Notion, Slack, Granola, Attio, Affinity, Salesforce, Apollo, WhatsApp, LinkedIn, GitHub, Claude, OpenAI, Word, Excel, OneDrive and SMS. Setup is either self-serve simple flows or a team-built configuration.
