What is Letter AI?

Letter AI is an AI-native sales enablement platform that generates training, coaching modules, and product content directly from your existing materials, such as blog posts, API documentation, and product specifications. Rather than treating enablement as a content management challenge, Letter AI focuses on rapid generation of personalised training programmes using what you already produce. The platform can turn a few blog posts and product documents into full training modules in minutes, instead of the weeks traditional tools require. Founded by a YC-backed team, it addresses a specific gap: teams launching new products or scaling rapidly need training fast, but traditional tools like Highspot are slow at content creation. Letter AI personalises output for individual reps based on performance data, making it particularly useful for mid-market and enterprise sales teams with regular product updates or rapid hiring cycles.
