Free calculators and tools for automation buyers
Interactive, no-signup tools to help you size and price automation platforms.
Automation Pricing Calculator
Compare Zapier, Make, n8n, and Rills pricing for your monthly volume: cheapest plan, monthly cost, and price per task.
Automation Payback Calculator
Build vs buy vs hire: compare DIY automation, an agency build, a VA, and keeping it manual. See your break-even month and 3-year savings.
AI Agent Token-Cost Estimator
Estimate monthly LLM spend for AI agent loops. Compare Claude, GPT, and Gemini token costs against the same job as a supervised Rills workflow.
Cron Expression Generator
Type a schedule in plain English ('weekdays at noon') and get the cron expression. Paste a cron and get plain English back, with the next five run times.
JSON Schema Generator
Build a schema for LLM structured outputs visually, or paste example JSON and let the tool infer it. Copy provider-ready snippets for OpenAI, Claude, Gemini, and Zod.
Approval Gateway
Add a human approval step to any Zapier, n8n, or Make workflow. One API call creates a mobile-friendly approval link; a webhook fires when someone decides.
