Overview

About SureThing.io

SureThing is an autonomous AI agent that remembers who you are and works on your behalf 24/7. Unlike AI chatbots that wait for instructions, SureThing operates proactively: it monitors your inbox, drafts replies in your voice, manages your schedule, tracks ongoing projects, and takes action across connected apps while you're focused elsewhere.
Its persistent memory sets it apart — SureThing remembers your preferences, your patterns, your contacts, and your goals across every session. It doesn't lose context, doesn't repeat mistakes, and adapts continuously to how you work.
SureThing is built for reliability over demos. SOC 2 certified and Google CASA Tier 2 compliant, it is designed for users who need an agent they can actually trust with real work — not one that breaks the moment it leaves the slide deck.
Early adopters include a technical director who contributed code to OpenClaw and calls SureThing "the Mac of AI agents," and solo founders executing full go-to-market launches alone.

About WriteVoice

WriteVoice is your AI-powered thinking partner, designed to transform your spoken thoughts into polished, ready-to-use text at the speed of conversation. It goes far beyond simple dictation by acting as an intelligent editor that lives right in your keyboard. The core idea is simple: you click record, speak naturally as you think, and WriteVoice delivers clean, accurate, and well-structured text. It's built for anyone who needs to write anything—from quick Slack messages and client emails to detailed meeting notes, project specs, and long-form content—but wants to break free from the slow, frustrating process of typing, especially on mobile.

The tool is perfect for busy professionals, managers, creators, and teams who value both efficiency and privacy. Its main value proposition is a seamless, "privacy-first" workflow: it captures your brilliance without killing your flow, never stores your recordings or transcripts, and works directly within the apps you already use like WhatsApp, Gmail, Notion, and Slack. By turning rambling voice notes into actionable plans, professionally-toned messages, and publish-ready content in seconds, WriteVoice helps you communicate clearly and get more done, directly from your voice.
