A Shuttlewright research tool
Make the next move. Bring the evidence.
For founders and marketing teams: collect what competitors actually say, separate your interpretation, and choose what to test.
Free local workbench. No account. No estimated traffic numbers.
The conclusion is still yours
One trail. Every guess labelled.
Every test points back to evidence IDs, a named owner and a decision rule, so a neat brief cannot hide a guess.
Separate inference from fact.
Observation is what a source says. Inference is your reading. Unknown stays a question.

Test with a rule.
Each campaign test cites evidence IDs, has an owner and a decision rule written before the result.

Before you use it
Plain answers.
Does it research for me?
No. You read public sources and enter short notes. It does not fetch links or invent missing data.
Are the numbers verified?
There are no estimated traffic or demand numbers. Source notes are not verified by this software.
Where is my work saved?
Only in this tab's memory. Export before leaving or refreshing. There is no account or autosave.
Can I use private research?
Do not put confidential material in a public demo. Keep exported packs within your approved audience.
What does the example represent?
A synthetic rehearsal, not real competitors or market evidence. Example URLs use reserved example domains.
Can I purchase a service?
Yes, human research services are available by invoice after the scope is agreed. No payment or order is accepted on this site.
