One plan. That's it.
Not a subscription. Buy the days you actually use.
ZENIN pricing is one plan: $70 for any 7 days of use ($10/day), as of October 2026. Every tool — live word cloud, polls, Q&A and AI brainstorming — is included, and there is no participant cap or per-seat fee. It is not a subscription, so there are no idle months and nothing renews. The days do not have to be consecutive: pick them one at a time within 90 days of purchase. There is no free plan or trial.
