Business case bench / v1.0
Build the AI business case, one pigment at a time.
Turn a Gen AI idea into a five-year cost, benefit and risk projection, with the payback year, peak funding need and NPV a sponsor will actually ask for.
- No account
- No telemetry
- Apache-2.0
Method
Three reasons the numbers hold up
Most AI business cases fall over in the same place: benefits estimated more generously than costs, annual figures starting in the wrong year, and nobody able to name the peak funding need.
Checked against the source workbook
Every figure derives from something you entered. A regression suite guards payback, ROI, NPV and IRR so a refactor cannot quietly move a number.
Your figures never leave the device
Runs entirely in your browser with React as the only runtime dependency. No backend, no sign-up, and it keeps working offline.
Feedback
What reviewers look for, and what the tool is built to answer
“The empty stakeholder roles being the finding is exactly how a steering committee reads a brief.”
Program sponsorIllustrative
“Seeing peak funding need next to payback year stops the ‘when do we break even?’ argument before it starts.”
Finance partnerIllustrative
“Nothing leaves the browser. That alone made it easy to approve for use with draft figures.”
