Zelto has three plans: Free, Observability and Improve. Every organization starts on Free. The in-app Plans view and the public pricing page show the current prices and limits; this page explains what they mean.

​
What each plan includes

Everything else is available on every plan: connecting agents, importing or uploading conversations, reading transcripts, and exploring traces.
A page for a feature your plan does not include stays in the sidebar. It explains what the feature does and which plan unlocks it. Nothing you already have is removed when you upgrade.

​
What counts toward the limits

  • Conversation minutes are the length of the conversations Zelto analyzes in a month. Each conversation counts once, by its duration. Text conversations, whose metadata.channel is text, chat, web-chat, sms, whatsapp or in-app, use no minutes. A conversation with no duration is not counted or analyzed until one is recorded, and shows Not analyzed: no duration recorded; send call.durationSeconds or call.startedAt and call.endedAt with it.
  • Spans and logs are the telemetry your agents send. A trace is the step-by-step record of one agent run. Each step is a span. Logs are the text messages your agent writes. Spans and logs count together.
  • Connected agents are the agents that send conversations to Zelto.
Usage above your included amounts on a paid plan is added to the monthly invoice. The Usage and Billing tabs under Settings show where you stand. Included amounts start again on the 1st of each month at 00:00 UTC.

​
What happens at the Free limits

The Free plan is never charged, and it does not ask for a card. When you reach a limit, Zelto does not bill you; this is what changes instead:
  • 100 conversation minutes. A conversation is analyzed only if its whole duration fits in the minutes you have left this month. One that is longer than what is left is still received and stored, so you can read its transcript, but Zelto does not analyze it; a shorter conversation that arrives later and still fits is analyzed, so the meter can read 80 / 100 while a long conversation is skipped. Zelto decides this after it has answered your upload with 200, so the response looks the same either way. To see which conversations were skipped, look for Not analyzed in the Conversations list and in a conversation’s details. The Usage tab shows Not enough minutes left with the number skipped this month. Skipped conversations are not analyzed retroactively when the month resets; upgrading analyzes the ones that arrive afterwards.
  • 10,000 spans and logs. Telemetry over the limit is still received.
  • 1 connected agent. A conversation for a second, new agent is refused with a 403 and the error connected_agent_limit, and it is not stored. The Usage tab shows how many conversations were refused. Conversations for the agent you already have keep working.
  • 1 report. The one report is in total, not per month. A report that fails to generate is not counted.
To go beyond a limit, upgrade your plan.

​
Retention

Retention is how long Zelto keeps the content of your conversations, such as transcripts, recordings and raw provider payloads, and your traces, spans and logs. Zelto deletes older content every day. The conversation record itself and the metrics built from it stay, so your history and trends do not change.
  • Free keeps content for 7 days.
  • Observability keeps content for 90 days.
  • Improve uses the retention agreed with you.
Traces, spans and logs are never kept longer than 90 days on any plan. Open a conversation to see when its content will be deleted: the Content retention line in its details shows the date, counted from when the conversation was created. It is empty when your retention is unlimited.
If you cancel a paid subscription, your organization returns to the Free plan, including its 7-day retention. Content older than 7 days is then deleted.
Retention can also be set to a shorter period for your organization. Ask your Zelto contact if you need that. To ask about deleting your data sooner, see the Privacy Policy.
