CubeDot

AIcanbuilditfast.Cubedotmakesitbuiltright.

Cubedot turns your idea into a complete specification. Each layer signed off by you. Then it serves that spec to your coding agent.

The Problem

Prototyping is easy with AI.
Complex projects fall apart.

In the age of AI, context is everything. If not managed correctly, you end up with projects that drifted away from their original specification.

assumptions.log UNRESOLVED

// Features nobody wrote down don't get built - you find out in testing, or worse, after shipping. ✕Planning forgets.

// Five people prompting one codebase means five versions of the idea. The agent builds all of them. ✕Context scatters.

// Instructions files get ignored. Task lists get thrown out the window mid-session. The agent quietly does its own thing. ✕Plans get abandoned.

// Nobody checks the work against what was intended - until the people you built it for do. ✕"Done" means "the agent says so."

The cost isn't speed. It's rework.

spec driven development.

How it works

Plan the whole product

Feed Cubedot your raw inputs - notes, calls, documents, wireframes. It generates the complete spec, layer by layer. You edit anything, then sign off each gate.

$ cubedot connect repo linked ✓

Feed it to your agent

One command connects your repo. Your coding agent receives the committed spec piece by piece. It is served live, not remembered.

$ cubedot verify 3/3 criteria met ✓

Prove what was built

Every piece of work is verified against acceptance criteria. Every deviation is documented and recorded. You see real progress - live.

Step 1

Generate your spec with AI

Cubedot uses agents trained in best practices in product requirements specification to break down and generate all the product details in the same way a professional project manager would.

Specialized AI agents generate. You confirm.

01 Brief

Goals, audience, and what is explicitly out of scope.

02 Features

Features, functionalities, and user stories with clear acceptance criteria.

03 Tech stack

The stack and conventions your team will build on.

04 Wireframes

Every screen and the flow between them.

05 Database

Tables, columns, and how they relate.

06 Risks

What could break, scored and mitigated.

07 Sequencing

The order to build, so nothing is blocked.

08 Design

Colors, type, spacing, and full Figma API integration.

"The sheer amount of data it pulled out of my conversations and documents - I was pretty enthusiastic."

Frano CEO, Choncha - biotech startup

"Cubedot saved me a week of writing features and user stories and filled in so many gaps I would have missed otherwise."

Dom Project Manager, TAR - software development agency

You hold the pen.

Nothing enters the spec without your commit. Every generated artifact - every feature, screen, table, risk - is yours to edit, at any step. The AI proposes; you decide what the product is. Once you commit, that decision is exactly what the agent builds from.

You sign off everything going in. We verify everything coming out.

Step 2

Your agent reads the truth. And actually follows it.

Cubedot doesn't rely on the agent's memory. The committed spec is served to it piece by piece - one functionality at a time, pinned to the exact version you signed off. It can't drift from a plan it never has to remember. And if anything slips anyway, the verifier catches it.

"I don't need to feed Claude context. It knows every single thing about that project."

Petra Developer, Takeaway Reality - software development agency

No context ritual.

Open the project, ask what's next, start building. Sequenced by dependencies, resumed where you left off.

"The mental load starting work with Cubedot is much lighter than just with Claude. I would always pick up a project with Cubedot before one without."

Step 3

See what was actually built. Without asking.

Whoever owns the idea watches real build progress - what's done, what deviated, what's blocked - streamed live from the repo. No status meetings. No secondhand reports. You review what actually shipped, with the receipts attached.

FT-001 Daily streaks Done

FN-003-01 Social sharing - waiting on OAuth scope Blocked

"Done" is a claim. Verified is a fact.

When your agent finishes a piece of work, Cubedot's independent verifier checks it against the acceptance criteria you approved - and flags what's missing before you move on.

Code changed off-spec? Recorded as a deviation, not buried in a diff. Spec and build drifting apart? Detected, not discovered in production.

Every project keeps a ledger: built as specified, deviated here, pending there. Not trust. Receipts.

"The verifier is very useful - it prompts extra work if an acceptance criterion was not met."

Lead developer, early-access team

It takes more time to plan. That's the point.

We won't pretend the spec writes itself in five minutes. You'll spend real hours planning - reviewing what Cubedot generated, deciding what your product is, signing your name to it.

Built for teams building something real

Teams that answer to someone

When the people you build for expect what they signed off, deliver exactly that - with proof.

Teams building on AI speed

Five people and their agents, one committed spec. One coherent product - not five interpretations of it.

Teams where software is the side quest

The rigor of a seasoned product team, built into the tool. No methodology to learn, no process to police.
