# strata→signal > The front door of the strata→signal workshop — where we build AI software that > runs on computers we own instead of a cloud service. One promise holds the family > together: you can always see where an answer came from, and none of these tools can be > talked into making one up. Two products are live right now with no account and nothing > to install, everything they serve is generated on our own hardware, and the toolchain > underneath is going open source while the products we build with it stay ours. ## Start here - [The whole family, mapped](https://strata2signal.com/family.html): every product, tool and machine in the workshop, what each one does, and where to start. - [RuleSage](https://rulesage.strata2signal.com) — settle the rules argument, cited to the page of the actual rulebook, and "not in the book" when the book is silent. - [amble](https://amble.strata2signal.com) — walking tours with footnotes; every stop shows its sources. - [RealKeep](https://realkeep.strata2signal.com) — a living-world RPG engine whose world remembers you. - [design](https://design.strata2signal.com/gallery.html) — the gallery; every picture carries its own recipe. - [Research](https://research.strata2signal.com/llms.txt) — the bench in public: trials, receipts, and the losses beside the wins. ## The tools and the machines underneath - [SharpSignal](https://sharpsignal.strata2signal.com) · [Kiln](https://kiln.strata2signal.com) · [memory](https://memory.strata2signal.com) · [agency](https://agency.strata2signal.com) · [easel](https://easel.strata2signal.com) · [brain](https://brain.strata2signal.com) · [keel](https://keel.strata2signal.com) · [forge](https://forge.strata2signal.com) - Say hello: [strata2signal.com/contact](https://strata2signal.com/contact/) or hello@strata2signal.com.
