Worried your professor thinks AI wrote your essay? Solus proves you typed every word. It's free, it runs on Windows, and it takes about 30 seconds to set up.
Free forever. No credit card. Windows 10/11.
The question of epistemic access has long troubled philosophers of mind. In this essay, I will argue that…
AI-generated text has made professors skeptical of good writing. Solus gives you a way to prove authorship — not claim it.
AI detectors flag innocent students all the time. A Solus certificate is cryptographic evidence — not a probability score. It shows exactly what you typed and when.
Solus looks and feels like a normal word processor. You write, edit, delete, and revise normally. The signing happens in the background — you don't have to think about it.
Document content is encrypted with AES-256-GCM. Only your teacher (with the class key) can read it. X Point cannot read your essays.
The setup is different depending on how you're using Solus. Pick the one that matches your situation.
Your teacher gave you a join code and set up an assignment. When you submit, the signed .solus file goes straight to their dashboard.
Start with: Enter your class join code from your teacher.
Your school hasn't adopted Solus, but you want proof-of-authorship for a college essay, a portfolio piece, or a class where you'd like a receipt in your back pocket.
Start with: Download, write, save. No join code needed.
Not sure? Start self-directed — you can enroll in a class later without re-installing.
Go to write.soluseditor.com in any modern browser (Chrome, Edge, Safari, Firefox). Sign in with your school email. That's the setup — nothing to install.
Your teacher gives you a join code. Enter it in Solus to enroll in the class. Your assignments appear automatically.
Write normally in the Solus editor. When you're finished, click "Submit." Solus seals the document with a cryptographic certificate and sends it to your teacher. Done.
You don't have to do anything special. Just write. After a few normal sessions, Solus learns your typing rhythm — and every submission after that ships with the badge automatically.
Do your usual homework, notes, or drafts in Solus. About 8,000 keystrokes across 3+ days is enough. You don't have to type any particular way — just be yourself.
Solus captures your rhythm — your typing speed, pause patterns, how you edit. It's yours; nobody else can reproduce it.
Once enrolled, your submissions carry Verified Human™ automatically — provided the doc's typing pattern matches your baseline. If it doesn't (someone else typed for you, or you typed off a phone), that shows too.
We want to be completely clear about what Solus tracks — and what it doesn't. You deserve to know.
Does not monitor your screen, camera, or microphone.
Does not track activity outside the Solus editor window.
Does not know what tabs you have open or what you searched for.
Does not stop you from looking things up in a browser — research is fine.
Does not run background services or install kernel drivers.
Does not send your essay content to X Point — only your teacher can read it.
Many assignments require you to paste block quotes, citations, or source material. Solus supports this — pasted content is not blocked.
When you paste something, it's recorded in a separate "paste quarantine" section of your certificate. Your teacher sees:
Pasting a 50-word quote in a 2,000-word essay is transparent and expected. Pasting 1,800 words in a 2,000-word essay is also transparent — that's the point.
The rule of thumb: if you'd cite it in a footnote, paste it and cite it. Solus will show it transparently, and that's not a problem.
No. Solus tracks keystrokes only inside the Solus editor window, only while you're writing. It doesn't access your camera, microphone, clipboard (outside of paste events you initiate), browser history, other apps, or anything else on your computer. It has no background processes and doesn't run at startup unless you configure it to. You can read the Privacy Policy for exact details on what's collected.
No. Your teacher only sees your submission after you click "Submit." Nothing is transmitted while you're writing. The document is sealed locally on your device and sent only when you choose to submit. There's no live monitoring.
Solus logs paste events, but it doesn't block you from deleting what you pasted. If you accidentally paste something and immediately delete it, it will still appear in the paste log with a note that it was deleted. A single accidental paste of a few words is not going to be an issue — your teacher can see the full context. If you're worried, you can check your own certificate before submitting.
Solus is completely free for students — no trial, no hidden fees, no "premium student tier." Just open write.soluseditor.com and use it forever. Teachers (or your school) pay for the class management and dashboard features, but that cost is never passed to you.
Once you submit to your teacher's class, the file is stored on their dashboard. You don't need to keep your local copy after submission. Before you submit, treat .solus files like any important document — back them up to a USB drive or cloud storage.
Solus proves that the keystrokes in the certificate were typed while logged into your account, in the Solus editor, at the times recorded — and that the document hasn't been modified since. It doesn't claim to read your mind. But a document with 5,000 organic keystrokes, a normal typing pattern, and zero paste events is very strong evidence of human authorship — far stronger than any AI detector's probability score.
