What is Pika and what is it used for?
Pika is an AI platform for creating and editing video, images and sound, combining Pika's own models with third-party models in browser and iOS apps.
It is used to generate clips and images and to change videos that already exist. Two of its own features show the kind of use: Pikaffects turns a photo into an effect video (the user uploads a photo, picks an effect and generates), and Pikaswaps replaces subjects or objects in a video while keeping the rest of the scene. Pika's model catalog lists the Pika 2.5 family, and the pricing page names third-party models such as Seedance 2.5 and Nano Banana 2.
Usage is measured in credits. Each plan renews an allowance every month, and each generation spends an amount that depends on the model chosen.
Pika also publishes a separate API for developers, billed per request and outside the subscription plans.
