Seven Letter Launches Engine to Audit How AI Describes Brands
WASHINGTON – October 29, 2026 -- Seven Letter, a bipartisan strategic communications firm, launched Engine, an "Answer Intelligence" service that audits how seven AI platforms describe a brand, executive or issue and then builds a plan to change that portrayal.
Engine audits ChatGPT, Claude and five other AI platforms
Each Engine report draws on custom prompts run through ChatGPT, Google AI Overviews, Google AI Mode, DeepSeek, Perplexity, Copilot and Claude. It quantifies brand visibility, mentions, sentiment, top sources cited, top journalists cited and frequent prompts. A separate score measures narrative favorability, mention and citation rates, frequency and intensity, and prominence and placement.
The audit also benchmarks clients against competitors and flags AI-generated answers that contain negative themes or possible inaccuracies.
