Folders, Labels & Spam Filter

Your conversations are automatically organized into folders: one-on-one conversations in “Chats”, group conversations in “Groups” and spam messages in “Unnamed”. The “Unnamed” folder contains chats from numbers that haven’t been saved to your contacts. You can also create your own custom labels. Just click the ‘+’ or ‘add’ button above the conversation list and name the label. For example, if you have work-related conversations, create a “Work” label and drag & drop those conversations into the label name.


Send one-to-one messages to everyone in a folder. Just go into the folder that you have created to send a blast message to and then tap the folder title to reveal a drop-down menu. Hit “Blast” and you’ll be able to type a message that will be personalized for each contact. The ‘@contact’ will be replaced by the first word of the contact’s name, as saved in your phone. You can remove this for a generic message.

AI Features

Enable our optional AI assistant to receive personalized advice and data analytics on your conversations, mood tracking, and tag your contacts so Mei can act as a contact management tool.

Personalized Advice

With the AI assistant enabled, you can see a full personality profile showing you how you come across through texts. Unlike other personality tools that require answering questions, Mei doesn’t need any input to generate your profile. just the text messages already on your phone. You’ll get your personality across five primary dimensions: Openness, Conscientiousness, Extroversion, Agreeableness, and Neuroticism. Each dimension consists of 6 traits such as outgoing vs. reserved, trusting vs. skeptical, traditional vs. liberal. Mei will show you where you score in all 30 traits compared to thousands of people.

Mood & Journaling

With AI enabled, Mei asks your mood daily (a slider from sad to happy) and if there is something else you want to journal. What have you done today, anything in particular that happened or other feelings you had that you want to track. On the “User Overview” screen you’re able to track your own behavior. Both mood history and journal entry history will be displayed, so you can look back and see how your mood has changed over time. 

Contact Overview

If you click on a contact’s avatar and click “Contact Overview”, you’ll see their full analytic summary. Here you can add and remove tags, which allows for more refined intelligence and enables organization. You’ll also see how metrics have changed and trended over time. Mei can measure how balanced your relationship is through analyzing a range of features (e.g. number of texts, response times, length of messages, conversations initiated, emoji usage, punctation, etc.) The graph shows whether the balance of the relationship has moved to your favor or your contact’s and how this has evolved over time. You can also “Ask Mei” anything we have a model on.
