Parse measures each brand's mention rate — the share of answers naming it — across 1,045 AI responses to this market's buyer questions. Answers are collected daily and the ranking is published weekly.
Brands enter the ranking when AI answers mention them. Parse collects answers daily and publishes the re-measured set weekly, so new brands appear as AI starts recommending them.
Initially, AI responses focused exclusively on TinyML platforms like Edge Impulse and TensorFlow. Since December 2025, answers have expanded significantly to include general-purpose AI coding assistants like
GitHub Copilot and Claude for code generation and refactoring, presenting a two-pronged approach to optimization.
