Custom GPTs are powerful general assistants. Zivvo is a customer-facing AI agent that runs on your channels and answers from your real business data. Here's the honest break-down.
You can embed a Custom GPT iframe, but it only works inside OpenAI's own app — no native Instagram / WhatsApp / email coverage, no escalation queue, no record of replies, no accuracy check. For internal productivity Custom GPTs are great; for customer-facing AI they are not the right shape.
Zivvo uses Google's Gemini 2.5 Flash AI for the main thinking and a smaller AI for behind-the-scenes sorting. The exact models are invisible to you — what matters is that answers are checked against your info, and uncertain ones are handed to a human.
It depends on who is using it. For a 50-employee team needing an internal AI, Business at $25/user is cheaper than Zivvo. For a 50-message-per-day customer-facing inbox, Zivvo at £29 is cheaper than wiring multi-channel infrastructure around Custom GPTs.
ChatGPT Team is excellent for internal use — drafting, brainstorming, summarising tickets. It does not replace a customer-facing channel layer. Many small teams use ChatGPT Team for internal productivity AND Zivvo for customer-facing replies.
Not natively. The OpenAI API can power anything if you build it, but there is no "connect WhatsApp + Instagram + email and reply automatically" ready-to-use product from OpenAI. Zivvo is that product.
GPT-4 / GPT-5 makes up false answers less than older models but it still does. Zivvo runs every reply through a accuracy check against your business info and holds it back if it mentions anything not in your business info. That is a different architectural commitment, not a model-quality argument.
Yes — and so does Zivvo (image input on Instagram DM on Pro+ plans). The difference is again the channel-integration layer: Zivvo handles the connection to the platform, the escalation queue, the audit log, and the brand-voice tuning.
You can build a public Custom GPT and your customers can find it in the GPT Store. But they have to be ChatGPT users, find your GPT, start a conversation in OpenAI's app. Most SMB customers reach you on Instagram, WhatsApp, email — channels OpenAI does not connect to.
OpenAI: based in the US, and meets EU privacy rules (GDPR) through standard legal data agreements. Zivvo: EU-hosted (Hetzner Germany), GDPR-compliant by default. If EU residency is a hard requirement, Zivvo is the simpler answer.
Yes — and many teams do. ChatGPT for Business for internal team productivity, Zivvo for customer-facing channels. They solve different jobs.
