Listing Description Quality Checker

How Listing Description Quality Checker works

Press Load model once: your browser downloads Gemma 4 E2B instruction-tuned (web build) (2.0 GB) from this site and keeps it in its cache. Then add your text and press Check locally. The model runs on this device using your graphics card, so nothing you enter is sent to a server. Until the model is loaded, or if your device cannot run it, the tool falls back to a simple keyword check and labels the result as the fallback.

Gemma 4 E2B instruction-tuned (web build) is a small open language model from Google. The tool sends it the instruction below plus your text, asks for a JSON answer with fixed fields, and shows each field as a card. It runs at temperature 0, so the same input gives the same answer on the same device, though different graphics cards can word it slightly differently.

Inputs longer than 6,000 characters are cut to that length before they reach the model, and the result says so. The model only sees what you paste: it does not look anything up.

The instruction the model gets

You review a draft real estate listing description. Point out vague filler (charming, won't last, motivated seller, near everything), facts a buyer would want that are missing (bedrooms, bathrooms, square footage, lot, parking, updates with years, HOA), and any wording that could raise fair-housing concerns because it describes who should live there rather than the property (for example perfect for families, adults only, walking distance to church, exclusive neighbourhood). Suggest better phrasing, but never invent features, numbers or amenities the draft does not mention; use placeholders like [year] instead. This is not legal advice.

What it returns

• Overall: Strong, Needs work or Weak, then one sentence on why.
• Vague or filler phrases: Phrases from the draft that say little, quoted exactly.
• Facts to add: Property facts the draft leaves out.
• Fair-housing wording to review: Phrases quoted from the draft that describe people instead of the property, or empty if there are none.
• Rewrite suggestions: Two or three concrete rewrites, using [placeholders] for facts not in the draft.

Worked example

Limitations

• Small language models make mistakes: they can miss an item, merge two, or state something more confidently than the text supports. Check the result against your input before you rely on it.
• It needs WebGPU and about 8 GB of memory, so it is offered on desktops and laptops, not on phones and tablets. Devices that cannot run it get the keyword fallback, clearly labelled.
• Results describe the input you gave, not the real-world situation behind it. Review them yourself before acting.
• This is not financial, tax or legal advice. Confirm anything important against your own records and with a qualified professional.
