Who it is for
People who build a software product and still do their own marketing: founders and small teams with a live SaaS, app, developer tool or AI product, often building with an AI agent. They know what they shipped. They do not have a designer, a video editor or an agency, and they do not want one more tool to learn.
What it makes
- Videos. Launch videos, feature demos, explainers, app teasers, coming-soon teasers and more. Each video type is motion design written in code and rendered frame by frame, so the same prompt gives the same video. Your logo, colours, fonts, words and product screens go in. See every video.
- Ad creatives. One image per prompt, painted by an image model from your prompt and your brand, sized for the channel.
- Captions. Written for each platform, in your voice, with no hype words.
- Posts. Post now or at a time you pick, from the accounts you connect.
How it works
- Paste your site. Siren reads your logo, colours, fonts and what you sell into Brand DNA, the profile every video and image is made from.
- Say what you need in one line, in the app or from your AI agent.
- Siren makes it, writes the caption and posts it if you want. After a post goes out, its real likes, views and replies show what to make next.
What it costs
One launch video is $9.99 once at mysiren.ai/launch. Plans are billed monthly: Spark $19 (100 credits, 1 channel), Pro $49 (300 credits, 2 channels), Scale $149 (1,200 credits, 4 channels). A video is 25 credits and an ad creative is 10, on every plan. See pricing.
Where to use it
In the app at app.mysiren.ai, or from your AI agent: Siren is an MCP server at https://mcp.mysiren.ai/mcp for Claude, Claude Code, Cursor and ChatGPT. See Siren MCP and the API.
