Parfit is a company brain for AI teammates. It keeps what a company knows (email, documents, past work and decisions) in one knowledge base, with every answer traced to its source, and runs AI teammates on top of it. Employees use it by emailing a task to their AI, the way they would write to a colleague, so there is no new tool to learn. Parfit routes each step to the right model, including Claude Code, Codex, Gemini, Perplexity, Grok, DeepSeek and Kimi, all on one AI budget, so a company does not buy separate seats from each vendor or lose context when it switches models. One AI does the work and a different AI checks it. A per-person dashboard shows what each person's AI use costs. Zero data retention is the default, and SOC 2 is in progress.
