Spool cards from the app, shown with demo data.

Your shelf, in color.

Every spool is a card in its exact color, showing the grams left on it. Switch to a table when you want to compare numbers side by side.

  • Color-first spool cards

    Each card shows the filament’s exact color and how much is left on the spool.

  • Grid or table

    Browse by card, or switch to a table to compare spools line by line.

  • Search, sort, group and save views

    Find any spool fast, and group by material, brand or color. Save the views you use most: 3 per list on Free, 20 on Pro.

  • Your own brands, materials and types

    Set up the brands, materials and filament types you actually buy.

  • From label photo to spool

    Take a photo of a spool’s label and AI fills in the brand, material, color and weight for you to check.

Spoolsight Slicecast Pro: Your slicer already knows the grams.

Slice in Bambu Studio, OrcaSlicer or PrusaSlicer, and the job you’re about to print turns up in Spoolsight as a planned print, with your spools matched, the filament reserved and a “Will it finish?” check.

  1. 1

    Connect your slicer once

    Add Spoolsight’s small script to Bambu Studio, OrcaSlicer or PrusaSlicer on Windows, macOS or Linux. Setup takes about 5 minutes per computer.

  2. 2

    Slice as usual

    Bambu Studio and OrcaSlicer report every slice, so their slices wait in Incoming slices until you confirm the one you print, in one tap, unless you turn on Auto-plan. PrusaSlicer plans when you export or send.

  3. 3

    It’s planned for you

    Each filament lands on your spool of the same material, product line and color, or waits for you to pick one when nothing is a clear match. Its grams are reserved, and “Will it finish?” checks there’s enough left.

The script sends only the comment lines your slicer writes at the start and end of the file, plus the file’s name. Never your model or the print’s toolpath, and it skips the preview images.
