01
Understand the code.
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.
Maine-made. Built for Everyone.
Powerful AI.For the People.
If you can dream it, we will help you Build it.
Mainely Code Buildroom—FREE EDITION is getting bigger. We are bringing 3B, 4B, 7B, and 8B model options to free, local AI—so more people can learn, create, and build on their own terms.

Our mission
Not just more powerful technology.
More people able to use it.
Make state-of-the-art AI accessible, usable, and approachable for Everyone.Mainely Code · Built in Maine
Start with something usefulA little help.
A little help.
A lot more possible.
You do not need a grand plan. Start with a question, a small project, or that one task you keep putting off.
02
Make a useful script.
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.
03
Start something new.
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.
04
Untangle an error.
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.
The Buildroom family
Three editions. One ambition.
Start free. Grow when you are ready.
Buildroom’s next chapter starts with access—not a bigger barrier.
BUILDROOM
FREE EDITION
$0
A real starting point. Not a paid subscription.
- Private, local AI coding help on Windows
- Understand code, draft scripts, explore ideas
- 4B available in the current Store release
- 3B · 4B · 7B · 8B expansion coming
BUILDROOM
LITE EDITION
September 2026
Planned before the end of the month.
- The next step in local AI engineering
- Further upgrades follow the FREE expansion
- Aimed at more capable PCs and larger work
- Final capabilities and pricing at launch
BUILDROOM
ADVANCED EDITION
Late fall / early winter
Planned before the end of 2026.
- For more demanding engineering work
- Built toward higher-capacity workflows
- High-end hardware direction
- Final requirements and pricing at launch
Release roadmap updated September 5, 2026. LITE and ADVANCED dates are planned release windows, not present availability. Model support, hardware requirements, and capabilities are release-specific. The 3B / 4B / 7B / 8B FREE expansion is announced; it is not represented as already included in today’s Store download.
Secondary feature · Buildroom campaign
Just say NO to mystery token burn.
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.
- Scope before execution
- Budget before burn
- Diff before done
- Tests before trust
- Rollback before regret
- Proof before merge
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.
This is only the beginningOne mission.
One mission.
A much bigger world.
FREE EDITION opens the door. Mainely Code’s wider product family is built around distinct jobs—not one app pretending to do everything.

Explore FORGE If you can dream it, we will help you FORGE it.
Mainely Code’s FORGE is a planned local-first workbench for developing, modifying, training, evaluating, and exporting specialist models—and exploring new AI technologies.
Standalone by design. Development starting soon.
On the horizon · Human-centered cybersecurity AI
SRAOSHA Intelligence around your world.
Red teams, blue teams—we got your back.
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.
GUARDIANSRAOSHA hardens.
Security posture, evidence, validation, remediation, and the blue-team side of the loop.
ADVERSARIALDJINN pressure-tests.
Controlled pentesting, adversarial testing, Kali/WSL workflows, evidence collection, and retesting inside explicitly authorized scope.
Find→Prove→Document→Harden→Retest
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 developmentAI anywhere. Governed everywhere.
The Great North is our connected ecosystem. Providence is the architecture that keeps its responsibilities clear.
Is FREE EDITION actually free?
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.
Are 3B, 4B, 7B, and 8B all available today?
Not yet. The current Store release describes a local 4B model. We have announced an expansion to 3B, 4B, 7B, and 8B for FREE EDITION. Read the announcement for what is changing; check the Store release details before downloading.
What do 3B, 4B, 7B, and 8B mean?
The “B” stands for billions of model parameters. These numbers describe model size—not a guaranteed quality ranking. What a model can do also depends on its design, the task, and the hardware running it. Exact supported models will be identified in the release.
Will it work on my computer?
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.
Can I use it offline?
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.
If you can dream it, we will help you Build it.
