An AI Draft Needs an Editor
AI writers like Jasper, Copy.ai and ChatGPT learned from the web's average writing, so an unedited draft reads like everyone else's. It can look fine and still miss the people it was written for. The missing step is an edit, and an edit needs a target.
SEMalytics gives the edit a target. Enter a live URL in the free audit, or paste a draft into the SEMalytics app, and it scores the copy against your audience, shows which buyer types the copy reaches and which it misses, and points to the fix. SEMalytics scores and diagnoses. It does not write copy. The writing stays with you or your AI writer.
Paste, Score, Edit
| Step | What you get |
|---|---|
| Paste: enter a live URL in the free audit, or paste a draft from any AI writer into the app. | The free audit needs no signup. |
| Score: SEMalytics scores the copy against your audience across 8 dimensions grounded in 860+ peer-reviewed papers. | A coverage score showing which of the five buyer personality types the copy reaches and which it leaves cold. |
| Edit: each gap comes with the specific change to make: what to add, what framing to change, what is missing. | An edit with a target. You or your AI writer make the change, then score again to see the number move. |
Sample: A cold email to enterprise security buyers leans on ROI and precise process language. It reaches analytical buyers well and barely reaches relationship-oriented ones, because it never says how the purchase affects the team. SEMalytics flags that gap and points to team-benefit language. Two paragraphs change, and the draft now reaches buyers it was missing. (Illustrative sample, not a customer result.)
What the Coverage Score Tells You
The coverage score shows how many of your buyer types a piece of copy reaches. No copy covers every type at full depth, and trying to would read as incoherent. A strong result reaches the types that matter most to your audience, with no important type at zero. Zero coverage on a type your audience leans toward is the gap SEMalytics is built to catch.
Coverage measures audience fit. It does not measure response or revenue, and a high score does not promise a result.
Why Personality, Not Just Readability
Grammar and readability tools check whether copy is clean. They do not check whether it fits the person reading it. The Big Five personality model (OCEAN) predicts how people process information, weigh proof and react to risk. A buying committee is rarely one type: the CFO, the practitioner and the champion read the same page differently. SEMalytics scores for that spread. For the framework behind it, see the psychographic marketing guide.
Where Teams Use It
Website copy. Your homepage speaks to one buyer type and ignores the rest. SEMalytics scores the page and shows the gaps before a rewrite. See website copy scoring.
Email copy. Cold outreach and nurture emails often match the sender's style, not the reader's. SEMalytics scores each email against the segment it is going to. See email copy scoring.
Ad copy. Ad copy that misses the audience burns budget. SEMalytics scores the ad against your target audience before you spend. See ad copy scoring.
Brand voice. Brand voice guidelines describe style, not psychology. SEMalytics shows which buyer types your voice reaches and which it misses. See brand voice.
Already Using an AI Writer?
SEMalytics does not replace it. Keep drafting with Jasper, Copy.ai, ChatGPT or any other tool, then score the draft before you publish. The comparison pages show where each tool stops and SEMalytics starts.

Questions
How is SEMalytics different from Jasper? Jasper drafts copy. SEMalytics scores it. Once the draft exists, SEMalytics shows which buyer types it reaches and which it misses, so your edit has a target. Use both: Jasper to draft quickly, SEMalytics to see what to fix before you publish.
How does SEMalytics compare to Acrolinx? Acrolinx checks copy against your style guide. That is a different problem from audience fit. Copy can follow every style rule and still miss the buyers it is aimed at. SEMalytics scores whether the copy reaches the buyer types your audience leans toward. The two tools address adjacent problems.
What is a coverage score? It shows how well your copy reaches each of the five buyer personality types in your audience profile. Low coverage on a type your audience leans toward is a concrete gap, and SEMalytics points to the fix.
Does SEMalytics work for B2B and SaaS copy? Yes. B2B and SaaS copy tends to lean on features, ROI and process, and under-serves team outcomes and big-picture framing. A buying committee is not one personality type, so SEMalytics scores for the spread, not just the primary decision-maker.
What if I don't know my audience's personality profile? You don't need a psychometric report. A working profile can come from job role, industry and behavior you already know, such as senior engineers at mid-market SaaS companies. You refine it as you learn more.
Can SEMalytics rewrite my copy for me? No. SEMalytics scores and diagnoses. It points to what to change, such as the framing to add or the evidence type that is missing. You, or the AI writer you use, make the edit, then score again.
