What it does
Ingests unstructured input of almost any kind — documents, tables, images, video, audio, web pages — and emits clean structured data aimed at RAG pipelines and fine-tuning, which is the tedious half of most AI data work. Breadth means per-format dependencies and real compute for media, so start with the formats you actually have. Check which stages run locally before feeding it anything confidential. GPL-3.0.

omniparse FAQ
- Is omniparse free?
- Yes. It runs on your own machine, so there is no usage-based cost either.
- Do I need to install anything or write code to use omniparse?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does omniparse work on a phone?
- No. It needs a computer.
- Can I use omniparse commercially?
- The licence is GPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
