1. Free AI plans: $0 per month
Leiolai Free includes Leiolai 1, the flagship model, and Plus Ultra, the highest thinking depth. Leveling up your chip system to Silicon unlocks our highest tier of intelligence at no added cost to you.
The Leiolai app is free and no card is required. You can earn with Leiolai by contributing computation from your phone or PC, then use those earnings to ask questions without a monthly subscription.
If you ask me, this is the best plan on the list, but I might be a little biased.
ChatGPT Free, Claude Free, Gemini Free, Grok Free, and Perplexity Standard also cost $0. For model access and usage limits, see the best free AI plans in 2026.
2. Google AI Plus: $4.99 per month
Google AI Plus costs $4.99 a month with 400 GB of storage and twice the Gemini usage limits of Free.
3. ChatGPT Go: $8 per month
ChatGPT Go costs $8 a month, below the $20 Plus plan. It also includes Work and Codex.
4. Google AI Plus with 2 TB: $9.99 per month
Google AI Plus with 2 TB costs $9.99 a month. Both Plus versions give Gemini twice Free's usage limits, so this upgrade adds storage rather than a higher Gemini usage limit.
5. Google AI Pro: $19.99 per month
Google AI Pro costs $19.99 a month with 5 TB of storage, four times Free's Gemini usage limits, and access to Google's Pro model and Deep Research.
6. AI plans at $20 per month
