-# WhoAtX
+# Who At X?
+
+A tool for organisations and businesses to use internally, to help them find the right person to talk to about a particular topic, and to equip them to best communicate with them. In terms of naming, 'X' is your organisation or business. For example, a business called 'Acme' would call this tool 'Who At Acme?'.
+
+Each member/employee has a personal profile, including details like:
+
+- how people like to be talked to
+- how to be praised
+- pronouns
+- name pronounciation
+- etc.
+
+It also covers key professional information like:
+
+- what your areas of knowledge are
+- what projects you work on
+- what team you're on
+- your working hours
+- your time zone
+- etc.
+
+This is plugged in to an LLM (GPT) with search capability, so you can find the people you are looking for who have knowledge on a particular thing by asking it a question, with it responding the best matches and providing links to their profiles to enable you to approach them in the way they like to be approached.
+
+## Possible future features
+
+- linking to calendars to make it clear if people are available or away
+- embedding into Jira to make it easy to assign the right people to the right tickets
