01
Automation ROI calculator
For anyone deciding whether a task is worth automating: estimate the hours it takes now, the hours a workflow could give back, and the most a build could cost and still break even.
Runs in your browser. Your numbers stay here unless you press Send this estimate.
What it gives you
- Hours a month now, and hours back: expected and conservative
- A verdict: worth a closer look, borderline, or probably not worth it
- The most a build could cost and still break even
- Payback, once you add costs, in the currency you pick

What it gives you
- A keyword match score and a readability score, side by side
- The keywords you are missing, and the points each would add
- What the parser read, in the order it read it

04How they work
Fixed rules on your own device. No model, no upload.
Rule-based, not AI
None of these tools calls an AI model. Each runs fixed rules or arithmetic, and its page prints the rules in a Method block.
Nothing is uploaded
Your numbers, resume and files are read in your browser tab. Each tool page lists every request the page makes, so you can check.
No sign-up, no email
You get the result straight away. Nothing asks for an email address to see it.
From a free tool to a workflow you can copy.
Each workflow page walks through the whole job step by step: the fixed rules, the one AI step and what a person checks. Build it yourself in n8n, and book a call if you get stuck.
