Solus's core product is authorship verification, not plagiarism detection — those are different problems. But schools that also want a plagiarism scan can turn on the similarity add-on. It runs against Solus's own corpus for free; web-search (Serper) is paid, tiered so you never get surprise bills. Full details →
Solus corpus only — peer submissions inside your org. No web search. This is the default for every education plan.
Web-search on demand for occasional use. Optional monthly cap to prevent surprise bills.
Web-search unlimited for individual teachers who run plagiarism checks often. Predictable monthly cost.
Web-search enabled for the whole institution. Add cross-institution matching with peered orgs (bidirectional consent required).
Yes, always. Students never pay. The student-side Solus writer is free to use at write.soluseditor.com forever — no install, no credit card. We charge institutions and organizations for management, dashboard, and compliance tools; never the individuals doing the writing.
Your .solus files are yours. They remain valid and verifiable forever — the cryptographic certificate doesn't expire. If you cancel a paid plan, you lose access to team or institutional features, but every document you've created remains fully verifiable at verify.soluseditor.com without an account.
Yes. verify.soluseditor.com is free and public. Anyone — clients, partners, auditors, teachers — can drag a .solus file to the verifier and get the full 29-check audit (19 cryptographic + 10 behavioral). No account required, ever.
Yes — all paid plans have a 30-day free trial. For education plans, we also offer a pilot semester for teachers who want to run one class before committing. Email us at soluseditor@gmail.com to set one up.
