A brand new Mac app known as RPLY launches right this moment, designed to assist texters obtain “inbox zero” on iMessage.
Concentrating on those that typically neglect to answer and depart their associates on delivered for days, RPLY makes use of AI to establish missed texts and suggests responses to stop customers from unintentionally ghosting. The AI assistant can robotically reply to messages in a person’s inbox that haven’t acquired a reply for over 24 hours.
RPLY is the brainchild of Molly Cantillon, a 21-year-old Stanford dropout who created NOX, a personalised AI assistant for iOS backed by OpenAI’s startup fund.
“RPLY was constructed to deal with ‘textual content debt,’ mentally replying however by no means hitting ship, getting distracted, or simply forgetting. The core thought is making texting really feel much less like a burden whereas nonetheless sustaining genuine connections,” Cantillon instructed TechCrunch.

Though AI-powered sensible reply know-how has been round for almost a decade and is utilized by main tech firms like Google, Cantillon famous that she has but to see an answer like RPLY for iMessage.
RPLY’s iMessage assistant goes a step additional by analyzing a person’s complete textual content historical past to craft replies that align with their writing type and persona, leading to natural-sounding responses.
Taking inspiration from Inbox Zero, a preferred digital assistant for e mail, RPLY additionally filters out unanswered messages. It even offers customers with a transparent overview of unread texts, permitting them to see what number of of their messages want responses. This characteristic provides a fast abstract, making it simpler than scrolling by means of iMessage.
Cantillon believes that the unanswered message filter is “a easy however important characteristic that Apple surprisingly overlooks.”
The app additionally features a statistics web page that shows the common weekly response time and tracks an “inbox zero streak,” which tells customers the final time they’d zero unread messages. To make customers extra conscious of their texting habits, it shows stats like “These You Reply Quickest” and “These You Prefer to Ghost.”
Throughout our testing of the app, TechCrunch discovered that the AI replies sounded pure and demonstrated an understanding of context. The general public we messaged didn’t notice the responses have been AI-generated. Nevertheless, some customers observed one thing was off when the AI positioned a comma after “haha.” It additionally didn’t use any emojis, and we want it had.

RPLY has already attracted a good quantity of curiosity, having signed up 1,000 paid customers up to now. Cantillon stated that many individuals drawn to the app are in tech, inventive, and enterprise fields. The app can be focused to founders, recruiters, retail brokers, and different professionals who’re overwhelmed with crowded inboxes. School college students may discover the app handy as properly.
Whereas many individuals are drawn to RPLY for its useful options, it additionally raises the query: can counting on AI reduce the emotional connection we get from texting? It is a matter that’s come up earlier than with the rise of generative AI instruments, however it’s value fascinated with whether or not the convenience of utilizing AI is absolutely value giving up these heartfelt exchanges.
Moreover, to make use of the app, customers should grant permission for it to entry all their textual content messages and contacts. This requirement might elevate issues for some individuals, because it signifies that an AI would study private conversations with family and friends.
In line with RPLY’s privacy page, the app doesn’t use textual content content material to coach generalized AI fashions, and the corporate follows a “strict zero information retention coverage,” which means information isn’t saved and will get instantly deleted after processing. Additionally, RPLY says it doesn’t promote person information to 3rd events.
Cantillon added that RPLY provides a neighborhood Llama-based possibility (Meta’s AI mannequin) for customers who wish to maintain all textual content information processing solely on-device, guaranteeing no textual content information is ever uploaded.
It’s regular for AI techniques to require person information to perform correctly, however it’s necessary to notice that even when firms declare sturdy safety practices, breaches nonetheless occur. Chinese language AI firm DeepSeek lately handled an uncovered inside database that contained delicate info, together with chat histories. At all times concentrate on the privateness dangers concerned.
RPLY is presently solely out there on macOS units. Apple is thought for its strict App Retailer tips, which means that RPLY might have developed a Mac app as a strategic workaround.
Sooner or later, Cantillon envisions increasing RPLY’s availability to platforms similar to WhatsApp and Slack. Nevertheless, it stays unsure whether or not this can occur, and there could also be issues amongst customers on Slack, an app utilized by workers, relating to the willingness to share in depth info with an AI firm.
It’s additionally on the pricier facet: the bottom subscription prices $30 per 30 days after a 14-day free trial.
