Laika is an AI writing tool that helps writers by generating suggestions for character traits and creating visuals for their stories. It allows users to upload text, which is then used to train Laika to create a unique "brain" based on the user's writing style. Laika's features include creating visuals, generating snippets of text, and training private and public brain. It is created by a team with experience in tech, gaming, and writing, and has a growing community of writers who use the tool to enhance their work. Laika is in beta and is available for use with an account.
