It makes what you already have leaner, safer and more trustworthy, and proves every change it makes.
No AI writes or changes anything. It measures, it checks, and every change can be undone.
one network the other, interlaced, never touching
The modules
What it hardens
Eleven modules on one engine. Each finds one kind of weakness, proves every change with a check, and leaves anything it cannot prove to you. They run in the app on your own computer.
Code
Source code
Finds
Imports a file never uses, and top-level code that nothing anywhere in the project calls.
Checked by
The whole project is read to see what uses what; every changed file is parsed again, and the project's own tests run before and after.
Never
Tests, outside libraries, build output, or anything still in use.
Code that never runs
Finds
The app's own functions that a real session in Chrome never touched, measured exactly.
Checked by
Reported only: code that did not run in one session may still run in another mode, on an error, or online.
Never
It removes nothing by itself.
Security
Finds
Dependencies with published flaws, keys and tokens left in the project's files (masked in the report), scripts loaded from other sites, and dependencies never imported.
Checked by
Standard checks, including the public advisory database.
Never
It changes nothing in the project.
Media
3D models
Finds
Parts of a model that never change what you see, such as textures too faint to show and animation tracks that never move.
Checked by
The model is drawn before and after from several angles and sizes, and animations are played in both; only an unchanged picture counts.
Never
Textures are never shrunk: that changes the picture, so it is your call.
Pictures
Finds
What rides along in a photo: where it was taken, the camera, the software, the editing history.
Checked by
Both versions are decoded and every pixel compared; orientation and colour profile are kept.
Never
Your original is never changed; you save a cleaned copy.
Sound
Finds
Tags and padding inside a sound file.
Checked by
Both versions are decoded and every sample in every channel compared; loop points and cue markers are kept.
Never
Your original is never changed; you save a cleaned copy.
Words
Text
Finds
Stray spaces, doubled words, repeated paragraphs, page clutter and filler; and a summary made of whole sentences copied word for word.
Checked by
Every number, name, quotation and hedge word is counted before and after, and must match.
Never
Words inside quotation marks are never touched.
AI detector and humanizer
Finds
A score of the habits common in AI-written text, with every point shown; and a rewrite of the habits a rule can safely change.
Checked by
The same fact count as Text: anything that would change a number, name or quotation is held back.
Never
It is not proof of who wrote anything, and must never be used to accuse anyone.
Bias
Finds
How coverage of one event splits into sides, what every side still agrees on, and each side's loaded words.
Checked by
Articles are compared by the facts they share.
Never
It measures agreement, not truth.
Ask your documents
Finds
Answers to your questions in your documents' own sentences, each with its file and line; a partial answer names what is missing; sources that disagree are both shown.
Checked by
A question word found in none of your documents blocks an answer.
Never
It never writes an answer or fills a gap.
Money
Budget
Finds
Repeated charges and fees in a bank statement.
Checked by
Read on your computer only; the statement never leaves it.
Never
It is not financial advice; you decide.
Measured
Results on real files
Every figure below was measured on real projects and files, and every change was checked before it counted.
Area
Measured
How it was checked
3D models
2.0 MB proven removable across 98 of a finished browser game's 147 models, which were already compressed
Each model drawn before and after from 6 angles at two sizes: at most 0.31% of pixels moved, 47 dB or better. Animations played in both.
Source code
3 projects tested unused imports and code nothing calls, removed from copies of each
Each project's own test suite, before and after: 31, 28 and 10 tests passing, unchanged. No new errors when the pages load.
Pictures
Hidden details removed location, camera, software and editing history
Both versions decoded by Chrome and compared: every pixel identical.
Sound
Tags and padding removed loop points and cue markers kept
Both versions decoded: every sample in every channel identical.
News coverage
4 articles, 0 factions on one college football game; shared facts found in all of them
Loaded language 0.3 to 0.7 words per 100, against 4 to 7 in deliberately slanted test articles.
Your documents
Abstains when unsupported asked whether the conference fined the school, it answered "your documents do not say"
Answers are copied sentences with file and line; a key word absent from every document blocks an answer.
Honest scale: on the game's models the free saving was about 3%, because an earlier compression pass had already done the heavy work. The hardener reports what is there, including when there is little to gain.
What it is for
The problems it solves
Most of what slows software down, leaks private details or misleads a reader is not missing. It is extra, hidden or lopsided. The hardener finds it, fixes only what it can prove is safe, and hands the rest to a person.
Weight that does nothing
Code that nothing uses, model detail that never reaches the screen, filler words. Removed only when a check proves nothing visible or working changed.
Exposure you cannot see
Where a photo was taken, which software made a file, keys left in source code, dependencies with known flaws.
Fragile points
The one part everything rests on, and changes with no way back. Pointed out for a decision, never changed behind your back.
Slanted or machine-sounding text
Articles about the same event that split into sides, and what every side still agrees on. Writing that reads as AI-made, scored habit by habit and rewritten by rule.
Answers you can check
Questions answered from your own documents, in their own words, with the file and line. When they do not say, it says so.
Trust
The same input gives the same answer every time. It runs on your own computer, and nothing is sent anywhere.
The shape
Why a minimal surface
The Schwarz Diamond is a surface found in nature and in engineering: it divides space into two interlaced channels with the least material for the most surface. Its properties are the questions the hardener puts to anything you give it. The shape decides what to look for; plain measurements and checks give the answers.
01
Least material, most surface. Nothing is there that does not do work.
What carries nothing?
02
Every point is held up by the lines beneath it. Nothing floats.
What holds up what, and what is floating?
03
Load gathers along certain lines. Some parts carry far more than others.
Where would one failure bring the rest down?
04
Two networks, woven together, that never touch.
Which sides keep to themselves, and what crosses between them?
05
Every turn of 90 degrees opens a new direction. Waste, security, reliability and resilience are measured apart.
Does a saving here cost something there?
Without AI
Measure, do not predict
A language model
predicts the likeliest words
can be confidently wrong
can answer differently each time
usually sends your files to a server
The hardener
counts, compares and checks
makes a change only when a check proves it safe; otherwise it holds back and says why
gives the same answer every time
runs on your computer; nothing leaves it
Limits
What it does not do
It does not write. It cannot compose new sentences or new code; it removes, rearranges and quotes.
It matches what is written. Two articles saying the same thing in different words can be missed, and so can an answer phrased differently from the question.
It measures agreement, not truth. A consensus is what the sources share; they can all be wrong together.
Its style score is not proof. It can say text reads like AI; it cannot say who wrote it, and should never be used to accuse anyone.
It leaves judgment to people. Anything it cannot prove safe is reported, not changed.
