Mainely Code Buildroom—FREE EDITION
If you can dream it, we will help you Build it.
Big possibilities. Zero price tag.
Useful AI should be within reach. Buildroom FREE 1.8.5 combines local model choices, repository work, review, verification receipts, and early Autopilot workflows on compatible Windows hardware.
Getting started
Start small. Make it yours.
A practical way into AI coding, whether you are learning your way around or know exactly what you need.
Prepare your local model.
Follow the app’s first-run setup and initial model download. Your machine does the local AI work.
Bring one useful question.
Ask about some code, draft a small script, or work through an error. Review the answer and test anything you plan to run.
Accessible does not mean every model fits every computer.
Start with the current Store requirements. Available RAM, processor, graphics hardware, model choice, and task size all matter. We are not promising that 7B or 8B will run comfortably on every PC.
Announcement · September 5, 2026
We are making FREE a bigger deal.
3B, 4B, 7B, and 8B are included in FREE EDITION 1.8.5. Read the update.
Actual FREE EDITION interface
See the local-first welcome for yourself.
This supplied FREE EDITION capture shows the product introducing local use in plain language, asking how the person wants explanations delivered, accepting a project, and returning a visible receipt instead of pretending a non-repository is ready to commit.
01 / Approachability
Plain language first.
The welcome explains local setup and asks how detailed the answers should be.
02 / Local control
Nothing downloads silently.
The person chooses when to set up a model and when to bring in a project.
03 / Receipts
The real state wins.
A non-Git folder is identified as a non-Git folder, with the next visible action explained.
Start with something useful
A 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.
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.
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.

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?
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.
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. 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.
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.
Does FREE get Buildroom Autopilot?
Yes. Buildroom Autopilot for Windows is available in FREE EDITION 1.8.5 as an early capability and is still being actively hardened. It keeps the target, reviewed plan, explicit authority, expected postcondition, result, and receipt visible. Check the installed release notes for exact controls and limitations.
