The two units: credits and slots

Mentova uses two related units to meter campaign cost:

• Credits - the currency your plan allocates each month. Credits are consumed when you run a campaign.
• Slots - the cost multiplier of each AI model. A model with 1 slot costs 1 credit per prompt; a model with 3 slots costs 3 credits per prompt.

Campaign cost formula

Campaign cost = number of prompts × slot cost per model (summed across all selected models)

Example: a campaign with 10 prompts running on Claude Sonnet (3 slots) and GPT-5 Chat (1 slot) costs 10 × (3 + 1) = 40 credits.

Model slot costs

GPT-5 Chat is a deliberate exception: a premium-priced model billed at 1 slot, because it is the default model of the ChatGPT class on every plan. Measuring your visibility on a cheaper stand-in than what chatgpt.com actually serves would skew your numbers.

Max-slots cap per plan

Each plan has a maximum number of slots you can select per campaign. This sets the ceiling for how many premium or ultra models you can combine:

A cap of 3 means you can pick one premium model (3 slots) or up to three standard models (3 × 1 slot), but not two premium models at once.

Monthly credit allocations

Important: Monthly credits reset every 30 days on every plan, FREE included (lazy reset triggered on the next campaign launch after 30 days have elapsed).

Bonus credit packs

You can purchase additional credits at any time from any paid plan. Bonus credits never expire, are shared across all your brands, and are consumed only after your monthly allocation is exhausted.

Common pitfall

Adding more models to a campaign multiplies cost proportionally. Before launching a campaign across many premium models, preview the estimated credit cost shown in the campaign launch modal. Running a quick test campaign with only standard models first is a good way to validate your prompts before committing premium-model credits.

Agent credits — a second, separate pool

The credits above are campaign credits (research). Separately, every plan includes a monthly pool of Agent credits that powers the Mentova assistant and content generation. The two pools are independent — spending one never touches the other.

Agent-credit costs are weighted per action: a chat message costs 1, a chat message with web search 2, generating a piece of content 5, applying a fix or re-evaluating an edited draft 1, repurposing into another format 5, and a PDF 1. They reset every 30 days, like campaign credits.
