Dewey

Dewey is an AI accountability buddy that tracks your to-dos and habits over SMS, sending personalized reminders and check-ins throughout the day. It also answers simple questions by text. Free for up to three open tasks, with a larger plan announced but not yet released.

Dewey is a conversational accountability tool that lives in your SMS inbox. Instead of opening another task manager, you sign up, hand over your mobile number, and add to-do items the way you would text a friend. Dewey replies by text, nudges you about open items, and checks in on the habits you are trying to build or break. The premise is simple: most productivity software waits passively for you to return to it, while Dewey reaches out to you on a channel you already check dozens of times a day. The product does two jobs at once. The first is task accountability: you tell Dewey what you need to do, and it sends personalized reminders plus periodic nudges so nothing quietly slips. The second is habit support: throughout the day Dewey checks in on how you are doing, which gives you a running record of whether a new routine is holding. Beyond that, Dewey answers simple questions you might otherwise search for, such as recipe requests or quick historical lookups, so the same thread doubles as a lightweight assistant. It fits best for people who bounce off dedicated task apps and need an external prompt rather than a better dashboard. Students, freelancers, and anyone working without a manager or team to keep them honest are the natural audience. In the wider market Dewey competes less with full project suites and more with habit trackers, reminder apps, and the nagging friend archetype. Its differentiator is delivery method plus a conversational interface, not depth of planning features. Current scope is deliberately narrow. The public roadmap lists basics still in progress, including remembering specific reminder times and repeating reminders, and Dewey does not yet support heavy customization. Default cadence is every three hours between 7am and 9pm in the timezone used at signup, and you can change frequency by texting Dewey. Setup takes minutes and requires no new app on your phone.
