Synorigin
Frequently asked questions
Is there a free version of Synorigin?
No. Creating an account is free, but every check is paid. You can try Synorigin once with a First Check for $2.80, or subscribe to Pro for $20 a month. See pricing.
Is Synorigin just an originality checker?
Checking is where it starts. Pro adds Projects that remember how your idea develops, a permanent Ledger of every version with certificates you can share, and Drift Check, which keeps searching for new work after you have stopped. Projects, the Ledger and Drift Check each have their own page.
What is a Synorigin certificate for?
It is a dated, tamper-evident record showing that an exact piece of text existed in Synorigin’s Ledger at a specific time. Anyone can verify it without an account, and your idea itself never appears on it. It does not prove authorship or any legal outcome. How the Ledger works.
What does Drift Check do?
It re-searches one of your projects on a schedule - weekly, every two weeks, or monthly - and emails you only the work published or updated since its last run. More on Drift Check.
What is the difference between Vantage, Fathom and Quarry?
They are three depths of search. Vantage is quick, Fathom is the standard check, and Quarry searches most thoroughly and tests its own suggestions before giving them to you. Compare the depths.
Is Synorigin a plagiarism checker?
No. A plagiarism checker compares your text against existing text and reports matching wording. Synorigin does not compare wording at all - it reads the concept and reports what it structurally resembles. You can write something in entirely your own words and still have a premise that is 85% an existing genre skeleton. That is the thing Synorigin is built to catch, and a plagiarism checker would return nothing on it. Longer explanation here.
Is it an AI-writing detector?
No, and it is not doing anything related. AI detectors guess whether a machine produced the text. Synorigin does not care who or what wrote it - it asks what the idea collides with. Longer explanation here.
How accurate is the score?
The score is an AI-generated estimate, not a measurement. There is no objective scale on which an idea is a given percentage original, and any tool claiming otherwise is overstating what is possible. Treat the number as a rough signal and the reasoning underneath it as the actual product - the matches and the gap are where the useful information is.
Is my idea stored, sold, or used to train AI?
Your ideas are not sold and are not used to train any model. Synorigin runs on a paid commercial plan with its AI processing provider, and under those commercial terms, inputs and outputs are not used to train their models. Ideas you submit are saved to your own account so you can return to them, and you can delete any chat or your entire account at any time.
One thing worth being explicit about: to find comparable existing work, Synorigin runs a live web search, and search terms drawn from your idea are sent to a search provider as part of that. The privacy policy sets all of this out in plain language, including where information is processed.
Does it only work for fiction?
No. It handles story concepts, characters, plot structures, product ideas, business concepts, brand names and marketing angles. The example checks deliberately span all of these - one returns Google Smart Compose and Handwrytten, another returns Harry Potter and Star Wars, from the same system.
What if my idea really is original?
Then it says so plainly, without inventing a gap to fill the format. That outcome is deliberately kept rare and held to the same standard of evidence as reporting a real match, because a tool that tells everyone their idea is original is not telling anyone anything.
Will it tell me whether my idea will succeed?
No, and it will say so if you ask. Success, market timing and financial outcome cannot be predicted from a concept. When someone asks anyway, Synorigin separates the unanswerable part from the answerable one and re-grounds the reply in the originality read.
Can it check whether a name is legally free to use?
It will flag an obvious collision with an active, registered brand in the same category, and it treats that as a legal matter rather than a creative one. But it is not a registry search. Where a question genuinely turns on formal registration, it names the relevant trademark or patent registry as the place the authoritative check actually happens. Longer explanation here.
Will it show me the text of something similar?
No. It will not reproduce copyrighted material - no lyrics, no passages from books or scripts - even when asked directly and even when the reason for asking is to know what to avoid. It names the work, describes what it does in its own words, and points you to the source.
