Triangle counts, tri sorting and an AI filter for Sketchfab, right on the model cards.
Sketchfab doesn't show how heavy a model is until you open it. PolyPeek adds that information to every model card, lets you sort search results by triangle count, and helps you spot or hide AI-generated models.
Each model card gets a badge with its triangle count, color-coded by weight:
| Color | Triangles |
|---|---|
| 🟢 Green | < 100k |
| 🟡 Yellow | < 500k |
| 🟠 Orange | < 1M |
| 🔴 Red | ≥ 1M |
Hover a card to also see its vertex count.
Two new options in Sketchfab's Sort by menu: Tris: Low → High and Tris: High → Low. Broken models with 0 triangles are filtered out automatically when sorting from low to high.
A Hide AI checkbox next to Sketchfab's own filters removes AI-generated models from search results. If hiding them leaves the page nearly empty, PolyPeek loads more results automatically.
Models marked as AI-generated by their uploader get a solid AI badge.
Most AI uploads never tick that box, so PolyPeek also guesses: models whose technical data matches the fingerprint of AI generators (Meshy, Tripo, Hunyuan…) get a dashed AI? badge. Hover it to see why a model was flagged. The signals are:
- generic texture names such as
texture_0.png,Image_0.jpegortexture_pbr_v128_* - a single material for the whole model
- a watertight mesh with an exact 2.00 triangle/vertex ratio
- triangles only, no quads
- an AI tool named in the title, description or tags
Photogrammetry scans share some of these traits, so scan keywords, multi-material models and 4K+ textures count against a flag. The guess is deliberately cautious: it would rather miss an AI model than mislabel a hand-made one.
A second checkbox, Hide AI?, also hides the suspected ones.
Install PolyPeek from the Chrome Web Store. It also works in Microsoft Edge (allow extensions from other stores when prompted).

Adjusts Sketchfab's own search requests (runs in the page context) |
- Triangle count, vertex count and the AI flag come from Sketchfab's model endpoint (
sketchfab.com/i/models/{uid}). No API token is needed. - Requests are only made for cards that are visible on screen, with at most 4 at a time and automatic retry on rate limits.
- Results are cached in your browser for 7 days.
- Sorting uses Sketchfab's own
sort_by=faceCount/-faceCountsearch parameters. - Hide AI removes models with
isAiGenerated: truefrom search responses before the page renders them, since Sketchfab has no server-side AI filter. - Hide AI? removes a suspected card from the grid after its details arrive, and keeps loading more results so the page doesn't end up half empty.
PolyPeek relies on Sketchfab's internal web endpoints, not a documented public API. If Sketchfab changes its site, some features may stop working until PolyPeek is updated. Please open an issue if you notice something broken.
PolyPeek collects no data: no analytics, no tracking, no accounts. It only talks to sketchfab.com, and everything it stores stays in your browser. See the full privacy policy.
The original Tampermonkey userscript (Sketchfab Poly Count) is kept in legacy/ for existing users. It is no longer maintained; please use the extension instead.
