Zernio (formerly Late) describes itself as "marketing infrastructure for agents": social posting, ads, inbox, WhatsApp, SMS and calls behind one API key, with an MCP server included. Hermoso is an AI marketing agent and a marketing MCP. Both answer "how does my agent post and manage ads". Only one answers "and who makes the ad".

Where Zernio is genuinely better
- Channel breadth for the price. Around sixteen posting networks, with per-account pricing that falls to $1 at volume.
- Messaging as a product. WhatsApp, SMS, RCS, iMessage and Slack in one inbox, and phone numbers with calls. Hermoso does not sell numbers or answer SMS.
- Building a product on it. White-label OAuth, multi-tenant profiles and a large REST surface for developers embedding social and ads into their own SaaS.
- A blogs API for WordPress and Shopify, which Hermoso does not have.
Where Hermoso is genuinely better
- It makes the ad. 100+ image, video, voice and writing models, written against a brand profile built from your site, with your real product composited into the scene. With Zernio the creative has to come from somewhere else.
- Research before creative. The Meta, Google and LinkedIn ad libraries and organic TikTok, Instagram, YouTube, Reddit and Threads, ranked by how long each ad has run.
- Four more ad platforms. Hermoso also builds campaigns on Microsoft Advertising, Snapchat Ads, Apple Search Ads and AppLovin Ads.
- Nothing is metered per account. Connect every channel and ad account you have; posting and campaign management cost no credits.

Which one to pick
If your creative already exists and you need one API to ship it to every network and inbox, Zernio is a clean fit. If the ads do not exist yet, or you want the agent to do the whole job from research to a live campaign, use Hermoso. Some teams will reasonably use both. The longer version is on the Zernio alternative page.
