Plain Agent

PlainAgent helps beginners build a first AI agent or chatbot that actually works. Free guides walk through it step by step: pick one job, decide the trigger, give it the right knowledge and tools, write the rules and a system prompt, then test before you launch. There are agent templates written as spec sheets, each with a copyable system prompt and a test list, plus a free planner that turns your idea into a spec in the browser. No code and no hype.
