In a world where AI can produce anything, the ability to prove your thinking is human is a professional differentiator. Solus gives individuals and teams a cryptographic record of human-authored work.
Every field where clients, funders, or regulators are starting to ask: did a human actually write this?
Sign briefs, opinions, and contracts with cryptographic proof they were attorney-drafted. Give clients the certainty they're asking for.
Deliver client reports with a verifiable audit trail of human analysis. Your strategic thinking, certified on every deliverable.
Editors and publishers can verify articles are human-authored before publication. The byline means something again.
Submit proposals with proof of original human authorship — increasingly required by funders who have added AI disclosure requirements.
Sign research notes and reports to distinguish human insight from AI output. The certificate shows what you contributed and when.
Compliance-ready documentation that human judgment produced the work product. Audit-ready from the moment you save.
Law firm clients are adding "no AI" clauses to engagement letters. Consulting clients want to know their strategy wasn't generated. Publishers are establishing human-authorship policies. Grant funders are adding AI disclosure requirements.
This isn't hypothetical — it's happening now. Solus is the infrastructure for professional human-authorship certification.
Three steps. No new workflow. Clients verify without an account.
Every document is cryptographically signed to that individual — their key, their keystrokes, their timestamp. The signing happens invisibly in the background while they write normally.
Manager or team lead sees who authored what, when, and can review the full provenance breakdown for every deliverable before it goes to the client.
Clients, partners, and auditors drag the .solus file to verify.soluseditor.com. The full 14-point cryptographic check runs in seconds. No account needed.
Your team dashboard shows every deliverable, who authored it, when, and the full provenance breakdown. Client-ready verification reports in one click.
When a client asks for proof, you don't have to explain — you share a file. They drag it to the verifier. Done.
