PlainAgent

PlainAgent helps beginners build a first AI agent or chatbot. Guides walk through the steps: pick one job, decide the trigger, give it the right knowledge and tools, write the rules and a system prompt, then test before launch. It has 21 agent template spec sheets covering the job, trigger, inputs, tools, rules, a copyable system prompt and what to test, plus a planner that generates a system prompt from your answers.

The guides, templates, planner and newsletter are free. The only price shown is a EUR 600 per month sponsorship slot for advertisers.
