This free SERP and AI snippet preview tool shows how your page title and meta description will look in Google search results — desktop and mobile — with live pixel-width truncation, plus an AI-Overview-style preview of the answer an engine is most likely to quote. Type your title, description and URL and see exactly where each one gets cut off. No signup, nothing leaves your browser.
AI answer preview
Add opening content to see the passage an AI engine is most likely to quote.
How to use the SERP and AI snippet preview
- Enter your page title, URL and meta description. The character meters warn you before Google truncates either one.
- Toggle between Desktop and Mobile — the truncation point differs, because Google measures pixel width, not character count.
- Paste your opening paragraph into the last box to preview the 40–60 word passage an AI engine is most likely to lift as a direct answer.
- Rewrite the title or description until nothing important is cut off and the answer chunk reads cleanly on its own.
Why pixel width — not character count — decides truncation
Google truncates titles and descriptions by pixel width, so a title full of wide letters (W, M, capitals) gets cut sooner than one of the same character count in narrow letters. This tool measures the real rendered width in the same font Google uses, which is why the cut-off point shifts between desktop and mobile. Getting this right matters twice over now: the same clear, front-loaded writing that keeps your snippet intact is also what makes a page easy for AI engines to quote. That is the core idea behind answer engine optimization and generative engine optimization — and you can score a full page against it with the AEO Readiness Analyzer.

Frequently Asked Questions
How long should a title tag be?
Google shows roughly the first 580–600 pixels of a title on desktop, which is about 55–60 characters for average letter widths — but wide characters cut sooner. Aim to front-load your most important words so the meaning survives even if the tail is truncated. This tool shows the exact pixel cut-off as you type.
How long should a meta description be?
Descriptions are typically truncated around 920–990 pixels on desktop (about 155–160 characters) and a bit longer on mobile. Google often rewrites descriptions anyway, so treat the field as a strong suggestion: write one clear, useful sentence or two that match the query and read well if quoted.
What is the “AI answer preview”?
AI engines and featured snippets tend to lift a short, self-contained passage — usually 40–60 words — that directly answers the query. The preview shows the opening chunk of your content at that length so you can see whether it stands alone as an answer. Content that reads cleanly out of context is far more likely to be cited.
Does Google use my exact meta description?
Not always. Google frequently generates its own snippet from on-page text that better matches the specific query. A well-written description still helps — it is the default and it shapes click-through — but the on-page answer matters just as much, which is why this tool previews both.
Is this tool free and private?
Yes — completely free, no account, and everything runs in your browser, so nothing you type is sent to a server. It is part of the free Plain Intelligence resource hub.
