features
Everything a marketing team makes. From one prompt.
Videos, ad creatives, captions and posts, all in your brand. Then Siren posts them and remembers what worked.
01 · videos
Launch videos, teasers and product demos.
Type what you shipped. Siren picks the right format, writes the script in your voice, and renders a finished video with its own sound design.
- Motion built for your brand, not a stock template
- Voice-over when you ask for it, silent when you don't
- Your own sign-off sound at the end of every video

02 · ad creatives
Ads and posts, painted for your brand.
Every ad creative is painted from your colours, type and voice. Square for the feed, tall for stories, wide for X. Ask for a shape and you get it.
- Painted, never a recycled template
- Every feed shape from one prompt
- Your logo and palette on every one




03 · brand dna
Set your brand once. Everything obeys it.
Colours, logo, fonts, voice and the words you never say. Set it once and every render follows the rules after that.
- Upload your logo, pick your colours
- Banned words stay banned
- One workspace per brand, no crossover
Colours
Voice
Never say
04 · posting
Posted where your people are.
X, LinkedIn, TikTok (with your OK on each post) and YouTube. Post now, schedule the week, or let an agent post when the render finishes. Captions come written.
- Schedule in your own timezone
- Captions in your voice, per channel
- Nothing posts unless you say so
This week
05 · brand memory
It remembers what worked.
After you post, Siren pulls the real likes, views and replies. The winners go into Brand Memory, and your next prompt leans on them.
- Real numbers from your own posts
- Winners kept for the next prompt
- Kept 6 months on Pro, 24 on Scale

06 · api & mcp
Run it from your agent or your code.
Connect Claude, ChatGPT, Cursor or Grok over MCP, or call the API. Your agent makes the video, shows it to you, and posts it when you say so.
- MCP and API on every plan
- Same brand rules as the dashboard
- Schedule a post for when the render lands
