fix(blog): use current Sim terminology instead of legacy Mothership/Copilot names

Per the constitution language rules, Sim's own natural-language agent
surface is "Chat" and the agent you talk to is "Sim" — not "Mothership"
or "Copilot" (those are prior internal names, still used correctly in
the historical announcement posts but not for new content). Leaves
references to Zapier's and Microsoft's own "Copilot" products as-is
since those name real third-party features.

 - **Pre-built templates:** Sim includes 11 pre-built workflow templates covering OCR processing, release management, meeting follow-ups, resume scanning, email triage, competitor monitoring, social listening, data enrichment, feedback analysis, code review, and knowledge base Q&A. Seven of those map directly to the ideas in this article.
 - **1,000+ integrations:** Connect Slack, Gmail, GitHub, GitLab, Notion, HubSpot, Salesforce, Airtable, Linear, Jira, PostgreSQL, Supabase, and hundreds more via drag-and-drop.
 - **Multi-model support:** Run OpenAI, Claude, Gemini, Mistral, or xAI models in the same workflow. Bring your own API keys or use Sim's hosted keys.
-- **Copilot:** Use Copilot to generate nodes, fix errors, and iterate on flows directly from natural language. Describe what you want, and Copilot proposes the workflow changes.

 - **Knowledge Base and Tables:** Upload documents to a vector store and let agents answer questions grounded in your specific content. Tables provide structured data storage for agents that need memory.
 
 Sim is trusted by over 100,000 builders at startups and Fortune 500 companies, and is SOC2 compliant. It's also open-source and free to start, removing the evaluation friction for teams with security requirements or budget constraints.

-Not to get started. Sim's drag-and-drop canvas and Copilot assistant let you build and deploy agents without writing infrastructure code. You configure blocks visually, connect integrations, and define logic through the interface. For teams that want deeper customization, custom functions, and API access are available, but they're optional.

 The drag-and-drop editor lets you connect 1,000+ integrations with multi-LLM support spanning OpenAI, Claude, Gemini, Mistral, and xAI. You can chain AI models, route data through conditional logic, loop through records, and deploy results via REST APIs, webhooks, scheduled jobs, or chat interfaces.

For teams with compliance requirements, Sim is SOC2 compliant and offers self-hosting via Docker or Kubernetes, meaning your workflow data never has to leave your infrastructure.

 ### The third path: visual AI workspaces
 
-This is where purpose-built agent builders come in. Sim is an AI workspace, not just a workflow tool or an agent framework. It combines a visual workflow builder, Mothership for natural-language agent creation, knowledge bases, tables, and full observability in one environment. You get the reasoning capabilities of a code framework with the speed and accessibility of a visual builder, and you don't need to install anything locally.
