Brainboot sells cognitive engineering across four tiers — from free text strings to complete business operations. Pick the layer that matches the job.
Single text strings. Free.
The loss leader — curated, usage-capped prompts that are better than anything on PromptBase, and free to copy. No account required to browse.
Verified cognitive modules. Free or paid.
Executable units with typed I/O, test suites, and enforced invariants. A brain is what a prompt becomes when you engineer it like software — reliable, composable, measurable.
Multi-brain compositions. Paid.
Pre-wired graphs of brains that produce a specific outcome. A Blueprint is a department — it replaces a whole category of repetitive cognitive work with one button.
Multi-Blueprint workflows. Premium.
The top tier. A Circuit composes several Blueprints into a complete business function that runs in the background on its own cadence. A Circuit is a headcount you no longer have to hire.
A Prompt is a single string — the atom of the stack. Anyone can copy it. It runs once, in a chat window, and gives you an answer.
A Brain wraps one or more prompts in a typed contract — defined inputs, defined outputs, a test suite, and invariants the runtime enforces on every call. A brain is the smallest thing you can bet a business process on.
A Blueprintcomposes several brains into a graph that produces a specific outcome. The drafting brain's output becomes the QA brain's input. Brains fail and retry inside the blueprint boundary, so the outcome is all-or-nothing.
A Circuit composes several blueprints on a schedule. It runs in the background, produces a continuous stream of business outputs (150 SEO pages a quarter, 500 qualified leads a month, a complete company package), and replaces a team.
You can enter the stack at any tier. Most people start with Prompts because they're free, and graduate upward as the job gets bigger.
