Used by people from
Say it however it comes out
Lassu keeps what you meant, drops the ums and retakes, and rewrites the rest into a clear script read by a natural voice.
Built for teams
that teach
One recording becomes the format each team needs, from a new-hire course to a sales demo.
Training and onboarding
Courses new hires can follow at their own pace, in their own language.
SOPs and job aids
Procedures people can follow at their desk, written from the walkthrough.
Customer education
Help-center videos and articles from the same take.
Marketing and sales demos
Keep the strongest moments, skip the setup, end on the result.
Lassu turns the way your team already works into knowledge people can learn from and AI can use.
What every recording becomes
A natural voice, in your team’s languages
Keep your own voice or switch to a clear AI narrator, then publish the same video in French, Spanish, German and more.
The guide writes itself
Every recording also becomes a step-by-step guide with screenshots. Need an FAQ, a job aid or release notes? They come from the same take.
Knowledge from every recording
Searchable to the word
Every word is transcribed and searchable, so anyone can find a step and jump to the moment it’s explained.
Ready for your AI tools
Each video comes with a summary, chapters and a transcript that your own tools can read through the Lassu API.
Keep a video to your workspace, share it with the people you add, or with anyone who has the link.
