Mycel vs Otterly
The best agency programme in AI visibility, next to a system that also does the work.
What Otterly is good at
Otterly has thought harder about agencies than anyone else in the category. Its partner tiers give you extra prompts, pitch workspaces for prospect demos, unified billing across client workspaces and branded reporting — that is a real agency product, built by people who understood that the buyer resells.
The actual difference
Otterly is where an agency tracks whether ChatGPT names their clients. Mycel is where an agency runs. The overlap is one job: both ask the models and both produce a client-ready report. Everything either side of that is different — Otterly goes deeper on the measurement, Mycel carries the engagement it belongs to, the deliverable the client accepts, and the invoice that follows acceptance. An agency selling only that report may well be happier with Otterly.

Choose Otterly
- GEO is the whole service you sell and you want the deepest tooling for exactly that
- You already have a system you like for invoicing, delivery and client comms
- You want Looker Studio reporting specifically
Choose Mycel
- GEO is one of several things you sell and you are tired of five tools per client
- You want the report, the acceptance and the invoice to be the same thread
- You want the client's whole relationship in one portal rather than a reporting link
