What is Trainn?
Trainn is a video-first product documentation platform designed for SaaS companies. It enables teams to create video walkthroughs by recording screen sessions, then enhances them with AI-generated voiceovers, automatic annotations, and translations. Trainn focuses on visual learning through video guides rather than written help-center articles.

Key differences between KnowUp and Trainn
Trainn centers on video documentation — you record your screen, and it produces polished video guides. KnowUp focuses on written help-center articles with screenshots, generated autonomously by an AI agent. The key difference is format and effort: Trainn requires manual recording sessions; KnowUp creates and maintains documentation without human involvement. When your product UI changes, Trainn videos need to be re-recorded, while KnowUp detects changes and updates articles automatically.
?
Pricing comparison
Trainn offers tiered pricing based on the number of videos and features needed, with plans typically starting from a per-user/month model. KnowUp pricing is tailored to your product's complexity — based on audit frequency and number of workflows. Book a demo for a custom quote based on your product architecture.
