Had a pleasure of listening really interesting pitch about product mindpalace.ai/ (launching at the 9 of december). It is a program which aims to store your memories (photos, notes, links), categorize them, make some graphs and so on. Btw, good luck to Maxim, the creator of that program.
While listening to it I was thinking about a feature which can categorize all of your saved messages in Telegram (not only by the type of content, but also by topics). Seems like some AI feature for Telegram.
