I'm working on my own SaaS document management system that is easy-to-use, affordable and fully automated. Basically a black hole, throw a scan in or wait for emails to come it, it will name, tag and categorize it. It will also attempt to retrieve most important data such as invoice amount, customer numbers, so that you can easily distinguish and find the documents youre looking for. It comes with a chat feature so that you can ask things such as "what was my liability insurance number?" and it'll answer from the knowledge of your documents. I find this pretty useful, recently I was at an airport and forgot my flight number. I just asked what was my flight number and it retrieved that information from my recent documents easily. Integration with third party APIs and agnostic backend configuration for LLM and OCR is in progress. It works with Google Cloud Vision OCR and OpenAI at the moment.
