Tools
The genuinely-useful instruments the Wasteland builds: things you'd actually use and come back to, not things to read once. Ten, so far: each earns the room.
The Generator
Eleven verified math engines as voices on one clock, retuned live by one temperament, and every sound is a theorem, and you can lift the hood for the exact numbers. Dial in voices, capture scenes, chain them into a set, and export the whole arrangement as MIDI or WAV, or hand a finished track to another model as a single URL.
Easy Batch Prompting
Pour in a list of prompts and a roster of models; get back every answer in one comparison grid — fanned out live and entirely client-side, with per-model cost and latency. Bring your own key and it never leaves your browser, or try the offline mock with no key at all. Download the whole run as JSONL, byte-compatible with the open-source CLI. It's open source precisely so you never have to trust us with your key.
Sky Now
Name any place — or type its coordinates — and pick any moment. See where the Sun, Moon, and five naked-eye planets sit in that sky: altitude and azimuth, rise / transit / set, twilight, the Moon's phase. Every position is recomputed live from the canonical astronomical algorithms — nothing fetched — and the engine was checked against JPL Horizons before it shipped. Scrub through the next 24 hours; lift the hood for the exact numbers; hand any sky to someone as a single URL.
Still Awake
Log your coffees and see how much caffeine is likely still in you tonight — drawn as an uncertainty band (fast vs slow metabolizer), not the fake-precise single time every other calculator prints. It shifts the band for the few things that actually move it (smoking, estrogen contraception, pregnancy), names what it can't know, and refuses to invent a "safe" sleep threshold. Every number is cited (NIH, FDA, Mayo, Drake 2013); it runs entirely in your browser; and it's an honest estimate, not medical advice.
StrictCheck
Paste a JSON Schema and see, per provider — OpenAI, Anthropic, Gemini — exactly which keywords are enforced, silently ignored, or rejected in structured-output / tool-calling mode. A generic linter says "valid ✓"; StrictCheck says "valid — but Gemini will silently ignore your minLength, so the constraint you think you shipped doesn't exist," with the provider doc that proves it. Rules dated and doc-linked because providers move fast; corrected schemas for OpenAI and Anthropic; runs entirely in your browser.
The Metre and the Voice
A scansion bench that teaches iambic pentameter the way you learn an instrument: perform a line and watch three layers at once — the five-beat grid, the stresses the dictionary locks, and your own reading. Where a long word forces a stress off the beat, that's a substitution the poem makes; where a small word is free, the departure is yours. Every stress is the CMU Pronouncing Dictionary's, and the tool is honest about exactly where the lookup ends and the craft begins — it never fakes certainty about English stress. Twelve canonical lines from Shakespeare to Tennyson, plus your own. The first bench of the Prosody Workshop.
Field Desk
An AI chat client whose memory is a wiki you can actually read: alongside your conversations the model keeps a personal wiki it can list, search, read, and write, and you can open any page and see exactly what it knows. Bring your own Anthropic or OpenRouter key; chats, wiki, and key live in your browser's own storage, model calls go straight from your browser to the provider, and there is no account and no backend behind it: the tool is served as static files. Semantic recall runs locally too, on the same word-vector table that powers this site's search. Export everything as one JSON file whenever you like.
Measure Your Room
Play a six-second sweep through your speakers, or just clap, and get the reverberation time of the room you are sitting in, octave band by octave band. It is the engine that measured 270 real spaces for the survey stratum, pointed at you instead, and the thing it does that meters normally will not: it refuses any band your recording cannot support, and prints the reason. Before it shipped, the engine was benched against rooms whose answer was already known, degraded to what a laptop and a clap actually deliver, and the page prints that accuracy table rather than describing itself. Nothing is uploaded and nothing is stored.
Canvas Ratio
You have a rectangle: a canvas you are about to stretch, a frame, a photo crop, a screen. How common is that shape among real paintings? Type the two sides in any units and either order and it counts, in four open museum catalogues separately and never pooled, how many catalogued paintings sit inside your tolerance, whether your proportion is a crowded one or a gap between crowded ones, and the simplest whole-number ratio you match. It is a lookup into ~720,000 actual measurements, two binary searches deep, done in your browser. It also says the thing every such number needs: a percentage of catalogued paintings is not a percentage of paintings.
What Light Is That?
You are on a coast at night and something out there is flashing. A chart answers the forward question, what does that named light do. This answers the backward one: given what you can see from where you are standing, which real light is it? Give it the colour, the flashes in a burst, and tap out the period while you watch. It searches 40,559 real navigation lights, keeps only the ones above your horizon for your eye height and inside their advertised range, and blinks each candidate on its own printed schedule so you can hold the screen up and compare. Every exclusion comes back with a reason. It is loud about not being for navigation, and loud about the United States being almost entirely absent from the book it reads.
This wing is just opening. A tool here has to be something you'd genuinely use, so for now it holds ten, and we'd rather show real instruments than pad the shelf. As the Wasteland's lineages mature, the useful instrument inside each gets built and lands here. The playable proofs and exhibits live next door, in the Library and the Lab.
