You do not need a grand plan. Start with a question, a small project, or that one task you keep putting off.
Make unfamiliar projects a little less intimidating. Ask what a function does and why it works.
Explain this function in plain English. Walk me through the inputs, outputs, and possible edge cases.
Turn a repetitive job into a practical starting point. Read and test the result before running it.
Help me draft a PowerShell script that lists files by size. Start with a read-only version.
Give that idea a first shape: a simple page, a small component, or a front-end scaffold.
Help me create a simple HTML and CSS landing page for a local business. Keep the code easy to edit.
Bring a confusing error, log, or configuration. Ask better questions and find your next step.
Explain this error, identify the likely causes, and suggest the smallest safe check to try first.
Starter ideas, not guaranteed results. Review generated code and test changes before using them. Model availability and performance depend on your hardware and installed release.
Start free. Grow when you are ready.
Buildroom’s next chapter starts with access—not a bigger barrier.
A real starting point. Not a paid subscription.
Planned before the end of the month.

Release roadmap updated September 11, 2026. Buildroom—FREE EDITION 1.8.5 is available now with 3B, 4B, 7B, and 8B local model choices. LITE and ADVANCED remain in active development; final availability, capabilities, requirements, and pricing will be announced after release qualification.
Seven visual comparisons place Buildroom FREE beside familiar subscriptions, coding products, free agentic apps, and the wider AI-tool landscape—with the category differences left visible.
We are about to turn this campaign up when Buildroom’s LITE and ADVANCED EDITIONS reach the Microsoft Store. The message is already simple: AI coding should come with a scope, a budget, a diff, tests, rollback, and proof.
Six replayable browser games. Local high scores. Achievements. A rotating daily challenge. No account, no credits, no telemetry—and yes, one of them still lets you whack mystery tokens.
Decomposition. Multi-model coordination. Evidence at every handoff. Northstar is the flagship cognitive platform at the heart of The Great North.

Buildroom is one powerful product inside a wider Mainely Code family. Each product owns a different job. Providence keeps the handoffs governed.

Decomposition, multi-model coordination, routing, budgets, provenance, and executive arbitration for serious institutional work.

Mainely Code’s AI is being built to augment the person responsible for the decision—not replace them. Human judgment, context, governance, authorization, ethics, and operational authority stay with people while the system takes on more of the procedural grind.
Security posture, evidence, validation, remediation, and the blue-team side of the loop.
Controlled pentesting, adversarial testing, Kali/WSL workflows, evidence collection, and retesting inside explicitly authorized scope.
The person sets the scope. The person authorizes the work. DJINN-SRAOSHA is the planned adversarial counterpart—not an “evil mode”—and SRAOSHA remains the guardian that receives findings, hardens, and sends the result back through the loop.
Proudly Built with Mainely Code’s Buildroom—ADVANCED · Long-horizon developmentThe Great North is the ecosystem. Providence is the governed architecture.
Distinct products stay distinct. Authority, execution, trusted placement, access, evidence, and product acceptance remain explicit.

Mainely Code was founded by Justin Tahai in Maine. We build AI tools to augment people, with clear responsibilities, human control, and evidence behind the work.

Yes. Mainely Code Buildroom—FREE EDITION is available for $0 on the Microsoft Store . You do not need a paid Buildroom edition to start using it. Your PC, storage, and electricity are still your own resources.
Yes. Mainely Code Buildroom—FREE EDITION 1.8.5 includes 3B, 4B, 7B, and 8B local model choices today. The best fit still depends on compatible hardware, available memory, and the task. Check the Microsoft Store listing and the installed release notes for the exact model catalog and requirements.
The “B” stands for billions of model parameters. These numbers describe model size—not a guaranteed quality ranking. Model design, task fit, context, and the hardware running it all matter. FREE EDITION 1.8.5 identifies its current supported model choices in the app and release notes.
Buildroom is a Windows desktop app. Check the current Microsoft Store system requirements before installing. Model performance depends on available memory, processor, graphics hardware, and workload. Supporting an 8B model does not mean every PC can run it comfortably.
The current FREE EDITION is designed for local AI conversations after the initial setup and model download. Downloads, updates, and any work that explicitly uses online resources still need a connection. Local-first is not a claim that every possible workflow is offline.
