Merlin alternative: plans, limits and who should pick which
Merlin, from Merlin AI's own pages as they read on September 28, 2026: its plans, the limits it publishes, and what it says it does. Then what a message costs on each side, and who should pick which.
Other companies' plans checked . Updated .
Short answer
Merlin's cheapest paid plan is $180 a year per seat ($15 a month), and it publishes no message count for its paid plans, so a message's price on them can't be worked out. llmwise Pro is $20 a month for up to 31 GPT-6 Astra messages a month ($0.65 each), each model's count shown before you send.

Merlin's plans
Checked September 28, 2026. Prices change: the quote is what the page said that day.
| Plan | Price | In its words | Messages it states |
|---|---|---|---|
| Pro (yearly) | $228 a year ($19 a month) | “Billed $228 for a year” (Merlin pricing) | None published |
| Teams (yearly) | $180 a year per seat ($15 a month) | “Billed $180 for a year” (Merlin pricing) | None published |
What a message costs
Merlin publishes no price and count together, so there's no price per message to set beside llmwise's. Here's llmwise Pro's ($20), model by model.
| Where | Messages | A message |
|---|---|---|
| llmwise Pro, GPT-6 Astra | Up to 31 a month | $0.65 |
| llmwise Pro, Claude Opus 5.5 | Up to 62 a month | $0.32 |
| llmwise Pro, Claude Sonnet 5 | Up to 125 a month | $0.16 |
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
