banaxou/hostagram — reverse-engineered prompt

Build me a Python tool called Hostagram for basic Instagram OSINT on accounts I’m allowed to look at. I want to type in a username and have it collect useful public profile information, show it clearly in the terminal, and save the results so I can review them later.

It should be able to check usernames, emails, and phone numbers when that information is available or provided by me. I also want simple follow related tools, like seeing follower and following changes over time, listing viewers or visible account activity when possible, and getting a clear summary of what changed since the last run.

Please make it easy to install and run on Windows and Linux, with simple setup files and a requirements file. Keep anything sensitive like my own session information local in a text file and don’t print it. Do not try to bypass private accounts or access anything without permission. Look up current Instagram related docs online if needed.
