An AI meta description generator that measures in pixels
A meta description is the short summary you suggest for the text under your page in search results. This AI meta description generator writes five to ten of them from your page’s own text, then measures each one the way a results page lays it out — in pixels of 14 px Arial, against the widths most often quoted for desktop (about 920 px) and mobile (about 680 px).
Each description is also checked for your keyword, your call to action, numbers that aren’t on the page, clichés, and duplicates — against the other descriptions in the list and against your other pages’ descriptions, if you paste them. Pick one to see it in a desktop and mobile SERP preview with the keyword in bold, and copy it as a ready <meta> tag.
Writing happens in your browser — through its built-in AI or IBM’s open Granite 4.0 Nano model, downloaded only with your consent — or from template patterns that reuse your own sentences, so nothing about an unpublished page leaves your device.
How to write meta descriptions
- Enter the Page title and Main keyword, and paste the Page text — the opening paragraphs are usually enough.
- Choose a Call to action, How many descriptions and the Language.
- Optionally open Preview URL and duplicate check to add the page address and your other pages’ descriptions, one per line.
- Press Write descriptions with AI, or Template ideas to build them from your sentences without AI.
- Compare the pixel meters and notes, press the eye button to preview one, and copy it as text or as a
<meta>tag.
AI Meta Description Generator features
Desktop and mobile pixel meters
Measured with the canvas text API in 14 px Arial — the same method as SERP Preview — with the likely cut point shown.
Duplicate check across your site
Exact and near-duplicate descriptions (80 % word overlap or more) are flagged, in the list and against pasted descriptions of your other pages.
Grounded templates
Template patterns reuse the page’s best sentences — ranked by keyword, numbers and length — and fit them into 155 characters by dropping whole sentences or clauses.
Honesty flags
Numbers that aren’t in your title or page text, ALL CAPS, clichés and clickbait are flagged on every draft.
SERP preview and meta tag
Desktop and phone previews with breadcrumbs and the keyword in bold, plus a correctly escaped <meta name="description"> tag.
Worked example: a masala chai recipe page
With the sample page (three paragraphs about a masala chai recipe), keyword “masala chai recipe”, the “Get the recipe.” call to action and seed 1, the first three template descriptions are:
- This masala chai recipe makes two cups of spiced milk tea in about 10 minutes. Get the recipe. (94 characters)
- Masala chai recipe: crushing the spices just before brewing gives the strongest flavour. Get the recipe. (104)
- Learn how to make Indian spiced tea at home. This masala chai recipe makes two cups of spiced milk tea in about 10 minutes. Get the recipe. (139)
What the example shows
The second description had to lose a clause: the page’s sentence about crushing and simmering the spices was too long, so it was cut at the comma and the call to action added back. The third one borrows “how to make Indian spiced tea at home” from the title, in sentence case. All three keep the “10 minutes” fact from the page, so none is flagged for invented numbers; the third will probably be cut on phones (past about 680 px), which the mobile meter shows.
How long should a meta description be?
Google sets no length limit. Its snippet guide (Search Central, updated 20 April 2026) says there is no limit on how long a meta description can be, but the snippet is “truncated in Google Search results as needed, typically to fit the device width”. The figures used here — about 920 px on desktop (roughly 150–160 characters) and 680 px on mobile — are the widths most often quoted, not numbers Google publishes. Put the most important words first so a cut doesn’t lose them.
The same guide asks for a unique description on every page — “identical or similar descriptions on every page of a site aren’t helpful” — and warns that long strings of keywords are less likely to be shown. Google may also show text from the page instead of your description when that matches a search better, so a meta description is a suggestion, not a guarantee.

AI Meta Description Generator FAQ
How many characters should a meta description have?
Google has no character limit and cuts snippets to fit the screen. Around 150–160 characters (about 920 px) is the commonly quoted desktop width and about 680 px on phones, so keep the key message in the first 110–120 characters.
Does this AI meta description generator send my page anywhere?
No. Descriptions are written by your browser’s built-in AI or the open Granite model on your device, or built from your sentences by templates. Your text, URL and other descriptions stay in your browser.
Why does Google show different text from my meta description?
Google picks the snippet it thinks best answers each search. It often uses your meta description when it describes the page well, but it can show text from the page instead.
Should every page have a unique meta description?
Yes. Google’s guide says identical or similar descriptions across a site aren’t helpful. Paste your other pages’ descriptions into the duplicate check to catch repeats.
Is a meta description a ranking factor?
It isn’t used to rank pages, but a clear, accurate description can make people more likely to click your result.
Can I write meta descriptions in Hindi?
Yes. Choose हिन्दी or Hinglish; the AI writes in that language (Hindi uses the open model), and the pixel meter measures Devanagari with your browser’s fonts.
