Spark : Caption Writer
Spark writes captions for non-Instagram surfaces, YouTube descriptions, ad copy, podcast show notes, video overlays. Short, punchy, CTA-driven.
The benefit of running Spark
Three outcomes you get the week Spark turns on. Not features, not roadmap items: actual results your team will feel.
Captions that stop the scroll
Platform-specific rules baked in: TikTok hooks, YouTube tags, LinkedIn lengths.
Variants, not commitments
Every caption ships in 2-3 variants so you pick the sharpest.
Your voice, every time
Fed your sent folder, Spark matches your tone in about a week.
4 jobs, one agent
Every capability below is in production today. No roadmap items, no coming-soons.
Multi-surface captions
YouTube, TikTok, Facebook, ads, each with platform-specific character limits and hook rules.
CTA engineering
Every caption ends with one action. No 'thoughts?' filler.
A/B variants

What Spark plugs into
Spark does not replace what you already use. It routes through the tools your business lives in.

What you actually see when Spark runs. Example output below; all data fabricated for illustration, no real clients shown.
Spark runs with 2 teammates
No agent works alone. Spark feeds into, and pulls from, these agents in every workflow.
