Pre-Mortem Generator
Assume your plan has already failed. Find out why before it actually does.
A premortem runs the post-mortem first. Paste any plan, strategy or proposal; the model assumes it failed and works backward to the risks you are not seeing, with a fix for each.
This usually takes 3-5 seconds.
Deep takes a minute or two: four pro models answer, two critics review, one mediator writes the final call. Leave this page open and the result lands here.
Pre-Mortem Generator runs the moment you sign in, on the text you just pasted. Nothing to enter twice.

What is a Pre-Mortem?
A pre-mortem is the opposite of a post-mortem. Instead of analyzing why something failed after the fact, you assume failure before you start and work backward to find the causes.
Paste your plan
Any business plan, product strategy, project proposal, or decision document.
AI assumes failure
The model takes your plan and assumes it has already failed. It works backward to identify the most likely causes.
Get actionable risks
Receive 5-7 specific risks with probability, severity, and concrete mitigations you can act on today.
The pre-mortem technique was developed by psychologist Gary Klein. Research shows teams that perform pre-mortems identify 30% more potential problems than those using traditional planning.

Example Analysis
We're launching a SaaS tool for freelancers to track expenses. Target: US freelancers earning $50-150K. Acquisition via content marketing + freemium model. 3 months to MVP, team of 2.
Market Saturation
The expense tracking space has 50+ established competitors including FreshBooks, QuickBooks Self-Employed, and Wave. Two developers and content marketing won't break through without a specific angle these incumbents can't copy.
Pick one underserved niche (e.g., freelance designers with project-based billing) and build 3 features they can't get elsewhere. Validate with 20 interviews before writing code.
Frequently Asked Questions
A pre-mortem assumes your plan has already failed and works backward to find why. Developed by psychologist Gary Klein, it helps teams identify risks they'd otherwise miss because they're too invested in success.
Traditional risk assessment asks 'what could go wrong?' — which triggers optimism bias. A pre-mortem says 'this failed, tell me why' — which activates different cognitive patterns and surfaces risks people are reluctant to voice.
A single model catches real risks but has blind spots. The free run uses 1 model. Council puts 4 models on the same plan, ranks each risk by how many of them raised it independently, and maps where they disagree, which is often where the real danger hides.
We store your plan and the result so your receipt link keeps working; the receipt is private unless you share it. We use enterprise API agreements, so your content is never used for model training.
The free run puts your plan through 1 model. Council runs it through 4 and ranks the risks by how many of them raised each one, with a map of where they see different dangers. Deep adds two critics and a mediator for the plans where being wrong is expensive.
