About
Proto Notebook exists because prototype testing is still run on spreadsheets.
Product teams plan tests in one tool, collect results in another, and chase approvals through email. Decisions get lost, evidence goes missing, and the next prototype repeats the last one's mistakes.
The problem
Scattered test work
- Test plans living in shared drives and email threads
- Results recorded in personal spreadsheets, not shared
- Approvals that require chasing people for sign-off
- No record of what was tested, how, or why it mattered
The fix
One shared testing record
- Define the test before the first run — goals, criteria, owners
- Keep evidence and measurements tied to the prototype they belong to
- Route approvals through a clear, visible workflow
- Turn results into reusable product learning
Who's behind it
Built by a mechanical design engineer.
Proto Notebook is built by Anjal Patel, a P.Eng. with 15+ years designing products across plastics piping, consumer appliances, and nuclear power projects. That background means this tool is shaped by the reality of engineering workflows — not a generic project manager bolted onto test data.
In his day job, Anjal has planned and executed mechanical tests for products that must meet CSA and ASME standards, where the test record is part of the compliance evidence. Proto Notebook applies that discipline to every prototype team — big or small.
