Launch HN: Prism (YC P25) – Workspace and API to generate and edit videos

Hey HN — we’re Rajit, Land, and Alex. We’re building Prism (https://www.prismvideos.com https://www.prismvideos.com), an AI video creation platform and API. Here’s a quick demo of how you can remix any video with Prism: https://youtu.be/0eez_2DnayI https://youtu.be/0eez_2DnayI Here’s a quick demo of how you can automate UGC-style ads with Openclaw + Prism: https://www.youtube.com/watch?v=5dWaD23qnro https://www.youtube.com/watch?v=5dWaD23qnro Accompanying skill.md file: https://docs.google.com/document/d/1lIskVljW1OqbkXFyXeLHRsfMictCfuxGGwczAnB1vhk https://docs.google.com/document/d/1lIskVljW1OqbkXFyXeLHRsfM... Making an AI video today usually means stitching together a dozen tools (image generation, image-to-video, upscalers, lip-sync, voiceover, and an editor). Every step turns into export/import and file juggling, so assets end up scattered across tabs and local storage, and iterating on a multi-scene video is slow. Prism keeps the workflow in one place: you generate assets (images/video clips) and assemble them directly in a timeline editor without downloading files between tools. Practically, that means you can try different models (Kling, Veo, Sora, Hailuo, etc) and settings for a single clip, swap it on the timeline, and keep iterating without re-exporting and rebuilding the edit elsewhere. We also support templates and one-click asset recreation, so you can reuse workflows from us or the community instead of rebuilding each asset from scratch. Those templates are exposed through our API, letting your AI agents discover templates in our catalog, supply the required inputs, and generate videos in a repeatable way without manually stitching the workflow together. We built Prism because we were making AI videos ourselves and were unsatisfied with the available tools. We kept losing time to repetitive “glue work” such as constantly downloading files, keeping track of prompts/versions, and stitching clips in a separate video editing software. We’re trying to make the boring parts of multi-step AI video creation less manual so users can generate → review → edit → assemble → export, all inside one platform. Pricing is based on usage credits, with a free tier (100 credits/month) and free models, so you can try it without providing a credit card: https://prismvideos.com https://prismvideos.com. We’d love to hear from people who’ve tried making AI videos: where does your workflow break, what parts are the most tedious, and what do you wish video creation tools on the market could do?
