Recipient-panel skill
Get your draft challenged
AI stand-ins for the people who will read your doc list their objections before you send it.
Daniel Cohen, product lead
Product management tools I built and use, free to share.
9+ years in product across B2B and B2C, building with AI since November 2024 for my work and my life at home. AI helps me gather sources, catch edge cases and challenge how I frame a problem, then turn it into a practical solution sooner; the decision stays mine.
Use the tools, share them or message me to talk about them.
Tools to try on your own work
Product-sparring skill
Challenge a plan
Ask for the strongest counter to your plan and a test that could change your mind.
Second brain
Give Claude your context
A notes folder Claude reads at every session start, so you stop repeating who you are and what you decided.
How I work
How I use AI across product work
You frame the problem, make the call and sign off. At each step AI adds sources or a counter-argument before anyone else sees your draft. Start with the part of product work you are doing now.
Understand the problem
- 1Frame the problemAI more sources, and a counter to your framing
- 2Learn from usersAI personas from your segment rehearse the flow
- 3Define successAI checks your metric against the question and the data
Leave with a problem statement and a way to judge progress.
Choose and shape the work
- 4Make a decisionAI the strongest counter, then a stakeholder panel
- 5Scope the workAI simulated engineering and design readers question your brief
Leave with a reason for the work and clear acceptance criteria.
Deliver and learn
- 6Support deliveryAI checks each change against the brief
- 7Check the workAI a red team that did not build it
- 8Prepare the releaseAI simulated users read the release note
- 9Measure and learnAI checks the inputs and argues with your reading of the result
Leave with review evidence and a next decision.
Side projects
What the projects taught me
Building is what I love. AI lets me build these projects myself. Every build teaches me more about AI, limits and unfinished tests included.
Personalised storybooks with the child as the hero
A child's name, a photo and a two-minute form become an illustrated book with the child as the main character. It ships printed or as a PDF, in five languages, to paying customers.

Pre-bid software for general contractors
Parapet read construction drawings to build a scope of work, then ran bid lists, RFQs and quote comparison for estimators. I built it alone and stopped it in Sep '26, when extraction stayed below the quality line I had set.
