Solus is a desktop writing environment that cryptographically signs every keystroke with ECDSA-P256. When a student submits, you get a tamper-evident certificate — not a guess, not a score. Proof.
Schools mandate Solus. Students write. Teachers verify. The cryptographic certificate doesn't care about AI detector scores — it shows exactly what was typed.
See how schools use SolusLaw firms, consultancies, and publishers use Solus to prove deliverables are human-authored. Free for individuals. Team dashboards for organizations.
See enterprise featuresAI detectors produce scores. Plagiarism checkers flag patterns. Solus produces cryptographic evidence of exactly what was typed and when.
Every character typed in Solus is recorded with a timestamp and signed into an append-only log. Edits, deletions, and revisions are all captured — the full writing process, not just the final text.
Pasted content is quarantined into a separate record, not blocked. Students can still paste quotes and citations — those appear transparently in the certificate. The teacher sees exactly what came from the keyboard vs. the clipboard.
Each .solus file contains a certificate signed with ECDSA-P256. Any modification to the document — even a single character — invalidates the signature and is immediately detected during verification.
Every keystroke is timestamped and hashed. The editor looks and feels like any word processor — the signing happens invisibly in the background.
On save, Solus seals the keystroke log, paste events, and document content into a single .solus file signed with the student's ECDSA-P256 key pair.
The teacher opens the .solus file in the teacher dashboard or drags it to verify.soluseditor.com. The 14-point check runs in seconds — no account required.
Your teacher dashboard shows exactly what was typed versus pasted — with timestamps, keystroke counts, and a human-origin percentage. No more gut feelings. No more student disputes that go nowhere.
