## Description

Assertion is a software brand focused on helping developers work more effectively with AI coding agents through persistent memory and efficient model usage. Its main product, the Assertion agent, is designed for Macs with Apple Silicon and works as a desktop app or in the terminal. Rather than compressing long conversations and potentially losing instructions, it recalls relevant decisions and facts as work progresses. The service supports Claude, GPT, Gemini, and Grok models, with plans that bundle model usage at half the usual plan price, according to the company. Assertion also offers a free personal memory plugin for Claude Code, Cursor, and Codex, allowing developers to keep their existing tools while adding shared or individual memory. Team plans include pooled usage and shared memory, with administrative controls available on a premium tier. Users can review captured memories and their supporting evidence in Studio, and delete information they do not want retained.
