Castup
Castup is an AI-powered, human-perfected podcast editing service for creators. It handles all aspects of audio and video editing to produce publish-ready episodes.

Brief Overview of Castup
Castup is a podcast editing service designed to handle the post-production workflow for creators, from first-time podcasters to seasoned professionals. The platform operates as a done-for-you solution, combining artificial intelligence with a team of human editors to deliver polished audio and video episodes. The primary problem it solves is the time-consuming and often technical challenge of editing, allowing creators to focus solely on recording their content. By managing tasks like audio cleanup, mistake removal, and the addition of music and effects, Castup provides a streamlined path to achieving professional broadcast quality. The service delivers final, publish-ready files, including details like ID3 tagging, within a 72-hour timeframe, aiming to simplify the entire content creation workflow for podcasters.
Castup Key Features for Content Creators
- Comprehensive Audio Editing: The core service includes a full suite of audio enhancements. Editors clean up audio files, add intros and outros, merge double-ended recordings, manage mic bleed and echo, and trim recordings to create a seamless listening experience.
- Video Podcast Editing: For creators on the Vodcaster plan, Castup provides full video editing services. This allows podcasters to expand their reach by publishing their content on video platforms without needing to learn video editing software.
- AI-Generated Transcripts: As part of the initial process, the service uses AI to generate episode transcripts within 18 hours of file submission. These transcripts can be used for editing direction and can also be purchased as a finalized add-on for publishing on a website or blog.
- 72-Hour Episode Delivery: Castup commits to delivering a final, publish-ready episode within 72 hours of receiving the raw files and editing directions. This quick turnaround helps creators maintain a consistent publishing schedule.

This human-first approach ensures that the nuances of editing are handled with creative control and a professional touch, complementing the speed of AI-powered initial processing.
- Publish-Ready File Preparation: The service handles the final details required for publishing. This includes ID3 tagging for audio files, ensuring that metadata like titles and artist information is correctly embedded before delivery.
- Micro Cuts Add-On: For an additional fee, creators can opt for the Micro Cuts service, which meticulously removes filler words such as “uhs,” “ums,” and repeated phrases from the recordings to create a cleaner, more professional-sounding episode.
- Multi Cam Cuts Add-On: This video-specific add-on provides dynamic editing for multi-speaker podcasts. It creates exclusive screen time for each speaker with professional transitions, enhancing the visual appeal of the video episode.
