Sidekick: The agent that does the chore in the tab you're on
Siren makes launch videos and ad creatives in your brand from one prompt, and posts them to X, LinkedIn and YouTube (TikTok with your OK on each post). One video is $9.99; plans are Spark $19, Pro $49 and Scale $149 a month, and Siren works inside Claude, Cursor and ChatGPT over MCP. Updated 7 Nov 2026.
Your agent does a chore in the tab its user is on, on a lavender haze under clouds in your colour. The tools it works with circle on three rings and gather into your mark, a real Chrome window shows the page it reads with what it found in the side panel, a new tab fills a form field by field, and the finished job lands in its recent list. Every line settles in word by word and is spoken.
This is one brand’s version. Yours gets your logo, colours, fonts, words and product screens, in the same motion.
Made for
- Agents and browser extensions that work beside their user
- Filling orders, applications, claims, bookings and posts
- Light and sure, a product that just works
How you get yours
- Paste your site. Siren reads your logo, colours, fonts and what you sell.
- Say what the video is about. A launch, a feature, a price drop. One line is enough.
- Pay once and watch it render. One video is $9.99, no subscription. On a plan it is 25 credits.
