I set up my own chatgpt for analysing company reports — here's exactly how you can too

why i did this i spend a lot of time analysing company reports — annual filings, quarterly earnings, financial statements. i was using chatgpt and claude for this but had a few problems: privacy — i didn't want to upload sensitive financial documents to third party AI services cost — the subscriptions add up, especially if you want the good models control — i wanted to customise the system prompt, use specific models, and share access with a friend who does similar analysis so i decided to set up my own private chatgpt-like interface running on a rented GPU. the whole thing costs me less than £1 per session and my data never leaves a server i control. here's exactly how i did it. what you're building by the end of this guide you'll have: a chatgpt-like web interface you can access from any browser the ability to upload PDFs and chat about them (company reports, annual filings, etc.) a vision model that can read charts, tables and images from reports multi-user access so you can share i
