Learn the Novus apps
Core, step-by-step guidance for the tools, grouped by app and written to stand on its own. Each app has a deeper library inside the product itself; these are the essentials. For the full reference see the documentation, and for the stories behind the builds, the product blog.
Novus Examples
Getting startedGetting started with Novus Examples: find and download a sample file
Novus Examples is a free library of 2,558 test files across 17 categories and 221 distinct extensions, generated by deterministic scripts rather than collected, so each one is copyright-clean and ships with an exact spec sheet. This guide covers what the catalog holds, how to find the right sample for the tool you are testing, and how to download it in your browser with no account.

Use casesTest a background remover with the right sample images
A background remover is only as good as the hardest image you test it on. This guide covers which sample images from Novus Examples genuinely stress a cutout (solid versus busy backgrounds, hair and edge detail, transparency and grayscale) and how to run them through the NSS Background Remover.

Formats & batchTest a file converter end to end with sample files
A converter can accept a file and still produce the wrong output. This guide covers grabbing sample files across formats from Novus Examples (image to image, documents to PDF, audio, video, and archives) running them through Novus Convert, and verifying the result actually holds up.

Use casesSample file types explained: what each sample is for
A reference for the sample variants in Novus Examples that are easy to misread: transparent versus opaque, grayscale versus color, CMYK versus sRGB, tiny versus oversized images, and the deliberate zero-byte, corrupt, and wrong-extension files built for error-handling tests.

Getting startedBrowse by purpose: find fixtures by what you are testing
The /for routes skip the format taxonomy entirely. Pick OCR, ASR, segmentation, CSV parsing, schema validation, or JWT and get the fixtures that exercise that specific thing.

Use casesTest with clean and noisy pairs
Paired fixtures (clean and noisy, colour and greyscale, source and scanned) differ in exactly one property, which is what makes a before/after test mean something.

Getting startedRead a spec sheet and use what it tells you
Every file in the library ships with its exact properties: noise sigma, silence timestamps, form fields, encodings, dimensions, and the seed that produced it. Here is how to use them.

Use casesBuild an OBS scene from a broadcast template
The 48 templates in the four broadcast categories each ship an OBS-compatible scene collection: a JSON file you import to get a scene already wired to the overlay you just downloaded. This guide covers downloading the pair, importing, and the one relink step OBS requires, and why it cannot be avoided.
