About
MarsDataAI is an AI relationship assistant that helps you organize contact details, record conversations and remember the people and things that matter.

Whether you are following up with clients, working with partners or keeping in touch with people in your life, MarsDataAI helps you forget less, prepare for the next conversation and keep your relationships in order.
Everything that matters about a person, in one glance
MarsDataAI pulls facts about people from your conversations and sorts them into clear groups such as Basic Info, Business & Team, Tech & Tools and Mindset & Preferences. Every fact has a source: a person's Conversations tab collects every related chat and transcript, one tap from the original words.
Spot opportunities and risks before you miss them
As you chat or upload meeting transcripts, MarsDataAI picks out opportunities, risks and key signals as insight cards, each backed by an evidence chain of original quotes.
Walk into every meeting prepared
Ask for a pre-meeting brief built from the person's profile, recent insights, open reminders and past conversations, then get a copy-ready follow-up that matches your tone and the commitments you actually made.
Deep research you can watch
Approve the research plan, watch several research helpers work in parallel, and check every cited source by its real page title.
Reminders that get to work, not just ring
At the set time a reminder opens a MarsDataAI conversation from your prompt, and event alerts can reach your bound WeChat.
Private by design
Lock MarsDataAI with a 6-digit PIN, Face ID or Touch ID on iOS, or a browser passkey. MarsDataAI reads public web pages as a signed-out visitor and never asks for your passwords or cookies.
