Try kitty without an account

A fair amount of kitty works with no account at all.

The free tools

Seven tools at https://kitty.build/tools. Four are pure calculators that run entirely in your browser — nothing is sent to us, and they are free forever:

• TAM / SAM / SOM Calculator
• MRR & Runway Calculator
• Pricing Page Grader
• Kill-or-Continue Quiz

Three call the AI engine, which costs us real inference, so they are capped per day per network:

Tool	Runs per day
Idea Validator	3
Landing Page Roast	3
Startup Name & Domain Checker	20

Running the same input twice inside six hours is served from cache and does not consume one of your runs.

What the free tools are not

The Idea Validator gives you one pass reasoning from your sentence — no research, no sources. The full nine-board run puts specialist boards on it with live web search and citations. That difference is the whole product, and it is why the free version gives a real answer rather than a teaser.

Playbooks

Ten standard operating procedures at https://kitty.build/playbooks — numbered steps for decisions solo founders usually make alone, each with the relevant free tool embedded at the step where you need it. Validate a SaaS idea in 7 days, kill a failing venture without sunk-cost bias, set your first price, size a market with no research budget, get your first 10 paying customers, and others.

Read real verdicts

• https://kitty.build/verdicts — the public library of verdicts founders chose to publish
• https://kitty.build/killed — the Killed Club: ideas that got a NO-GO and were published anyway
• https://kitty.build/how-to — step-by-step founder workflows

When you're ready

Signing up is free and needs no card, and the one-time grant of 100 Treats covers a full nine-board validation (80) with change left for a website. Create an account.
