Heraldcast
AI agents that catch viral outliers in your niche ... early
Heraldcast runs AI agents that scan TikTok, Reels and Shorts for your niche and score videos by how far it outperforms its creator's audience, so you catch outliers while they're still climbing. Then it tells you why they work: a topic map with impact and saturation that shows open lanes before they're crowded, analyst insights on the formats and hooks behind the winners. Less doomscrolling for ideas, more knowing exactly what to film this week or simply understand the market
Hey Product Hunt! 👋
Short-form video is the largest attention market in the world, and almost every decision made on it, whether by brands, agencies, or creators, is still made on vibes. Trending feeds are noise: big accounts, stale virality, no way to tell a real signal from an algorithm's mood.
Heraldcast is an analytics layer that extracts the signal surgically.
It scores videos on where they're going to land, not where they are. When an agent picks up a video that's six hours old, it doesn't just read today's counters. It projects the video's settled performance from growth curves fitted nightly on our own corpus of measured trajectories, per platform. That projection is normalized against the creator's audience, so a small account's breakout outranks a celebrity's routine million views. The result is one number: how far this content will outperform its expected reach.
And the forecast is audited. Every early call is settled against reality at 96 hours and kept in a receipts ledger, hits and misses side by side. You know exactly how reliable the radar is before you put budget or production time behind it. No trend tool I know of keeps score of its own predictions.
Then it's turned into strategy. Each agent maps its corpus into topics and plots impact against saturation, showing you where demand is proven but supply hasn't caught up. An AI analyst decomposes the top performers into the formats and hooks driving them, and outlier-producing creators are tracked automatically.
Whether you're a creator, an agency running client accounts, or a brand deciding where content budget goes: proven, audited signals beat instinct.
Free tier, no card. Name a market in the comments and I'll post the signal an agent pulls from it. 🙏
