A document arrives
You drop in the file exactly as you have it: PDF, DOCX, plain text, no converting, cleaning, or fixing anything first. Even Polish characters, which trip up other tools across three different encodings, just work here.
utf-8 → cp1250 → iso-8859-2

An index is built
Content goes into a vector store that survives a server restart. Upload a document once and it stays; no re-uploading for every conversation.

The work gets done for you
Instead of guessing, you get a concrete result on demand: a summary, extracted dates, key points, reformatted text — one command, no digging through the file yourself.

Why you can deploy this without worry
- Only your people get access — authentication on every endpoint
- No one can flood the system with requests — rate limiting
- Conversation history is saved, not lost when a tab closes
- Ready to deploy on your own infrastructure — container image

Or a process that could be handed to a machine? Write to me and we will scope it. I am building a body of deployed work and taking on first projects — I will tell you plainly whether it is worth building, instead of pushing something you don't need.
