Pre-submission citation check

Catch a fabricated citation before your marker does.

Drop in your finished essay below. Solas finds every in-text citation, checks each against CrossRef, OpenAlex, Google Books, and Unpaywall, and flags any source that doesn't appear in any academic registry — including the ones AI quietly invented. You'll know in 90 seconds which citations are solid and which to fix, plus a downloadable report to keep for your records.

Create your free Solas account.

One tap with Google and the audit's yours — free, forever, no payment details. Your account is just so we can save your audits and tell you when Solas Pro launches.

Source Alignment

What is this?
— Alignment

What this means: Source Alignment is the percentage of your citations whose claims are faithfully supported by what the cited source actually argues. Markers downgrade most heavily for misused or overstated citations — improving Alignment is the fastest route to a better mark.

    Catch fabrications as you write

    The Solas Chrome extension cites your sources as you save them, verifies each one in real time, and warns you the moment a paper doesn't check out.

    Solas Pro — launching soon

    Unlimited audits, saved history, batch upload, retraction alerts. Drop your email — we'll let you know when it's ready and you'll get early-access pricing.

    Privacy. Your essay is parsed inside this browser tab and the whole document is never uploaded. To check whether each source actually supports the point it's cited for, Solas sends the sentence around each citation (a short “claim window”) plus the matching reference to our verification service, which uses OpenAI to make that judgement. We never send your name or any student-identifying information. Full privacy policy.
