Taken from the documented limitations in our Nodalist AI profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Nodalist AI (this page) | $5.99/mo (Starter) | Yes | Web | The free plan gives only 250 credits per month, 5 workspaces and one grounding session per day, and each AI action costs a varying number of credits. |
| Gemini Notebook (formerly NotebookLM) | Not published | Yes | Web, Mobile | Free tier has standard usage limits and 50 sources per notebook; higher limits need a Google AI Plus, Pro or Ultra plan, which Google says are only available in specific regions. |
| Perplexity | $10/mo (Education Pro (consumer, verified students/faculty)) | Yes | Web, API | The consumer pricing page is blocked to automated checks, so the Pro price could not be confirmed here, and free-tier Pro Search and Research access are described only as 'very limited' / 'limited'. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription. |
