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 ChatGPT (1 slot) costs 10 × (3 + 1) = 40 credits.

The number of passes per question does not change that cost: a model asked three times on the same prompt consumes the same credits as a model asked once. Passes exist to narrow the gap a model has with itself — two identical calls do not return the same list of brands — and they are set per model, from its real price.

Model slot costs

A slot represents spend, not an advertised tier. That is why the table above is not a straight copy of the tiers: Claude Haiku and Grok 4.5 are billed 2 slots because they write long answers and, in practice, cost about twice a common standard model.

ChatGPT Premium at 1 slot follows the same logic. It costs 4.4× more per call than its class default, but it makes a single pass per question where the default makes three: per prompt, the spend ends up only ~45% higher, which two slots would overcharge.

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. As of 2026-08-26 this ceiling is 6 on every plan, FREE included — it climbs whenever a model's slot cost rises (most recently when Google AI Mode moved to 2 slots), because a cap left behind silently crops your model selection instead of raising your spend:

A cap of 6 lets you pick one ultra model (5 slots) plus one standard model (1 slot), or two premium models (3 + 3), or six standard models — any combination up to 6 slots total.

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, an illustration 10, and a PDF 1. They reset every 30 days, like campaign credits.
