In plain English

PrintWise is a free tool for people who own 3D printers and use OrcaSlicer to prepare their models for printing. It runs locally in your web browser rather than in the cloud, and it helps you go from a raw 3D model file to a set of Orca profile settings tuned for your specific printer and filament. You upload a model, pick your printer from a large searchable list, choose a compatible process preset or let it generate one automatically, and select a filament, and the tool analyzes the model, suggests a print orientation, and produces ready to import Orca profile files. On Windows, getting started just means extracting the download and double-clicking a batch file, which opens the tool in your browser automatically. It works fully offline by default and does not need any Python packages installed beyond Python itself, since the app is bundled with everything it needs. The tool ships with a large built-in library of printer, filament, and process profiles pulled from Orca's own profile set, and it can also import filament information for products that are not already in that library, either from a specific website or from specs pasted in manually. Every time you run an analysis, the tool saves a folder containing the generated Orca profile files, a full export bundle, a report on how confident it is in its suggestions, and notes about the run. There is an optional feature that uses an external AI service to improve its suggestions further, but if that service is unavailable or rate limited, the tool simply falls back to working offline using its built in library and rules. This is an early tester release, and the author is upfront that it produces a strong starting point rather than a finished, calibrated profile: testers are asked to still check settings like temperature and first layer height in Orca before printing. The software is free to use for the 3D printing community but uses a custom noncommercial license, so it cannot legally be resold, put behind a paywall, or rebranded as a commercial product.
