Unbacked-claim check
Paste your homepage copy and get back each sentence that states a number, a superlative, a date or a claim about somebody else while carrying no source a reader could follow — the same detector the installed audit runs over every page of a site.
What it reads
This reads the ONE block of copy you pasted, sentence by sentence, and asks one question of every claim it recognizes: is a source present in that sentence?
- A number in public copy — a percentage, a multiplier or a magnitude — with no source in the sentence
- A price ("$49", "from $49 a month", "$80–$150") — a number your business will be held to, which only your own price list can confirm
- A superlative or a rank claim (fastest, only, industry-leading, "#1"), which is a comparative claim about everybody else
- A dated assertion, which goes stale silently unless the source it rests on carries a date
- A claim about a named third party, minus any name you declared as your own
What it does not look at
- evidence that lives on another page — this reads only what you pasted, so a source sitting on your about page, your pricing page or a linked PDF reads here as missing
- whether a source that IS present is any good, or whether it says what the sentence claims — this judges presence, not support
- a claim carrying none of the five shapes it knows: "our approach works better" has no number, no price, no superlative, no date and no name, so nothing here detects it
- whether a price is right: this tool has no price list of yours to check it against, so every price is flagged, and a source in the sentence does not clear it — a citation says where a figure came from, not what you charge
- numbers written as words — "nine out of ten" is a statistic to a reader and invisible to this
- whether a flagged sentence is actually wrong: a flag is a sentence to confirm before you publish, never a finding that it is false
Why unbacked claims cost you
A number with no source is the first thing a careful buyer, reviewer or AI answer stops trusting. Add a source, soften the wording, or cut the claim. Each row above tells you which sentence to look at.
