How do I choose an AI tool to generate documents?
When selecting the right tool, start by identifying the platform accessibility you require; if you need to work on mobile or desktop-mac, choose Runable. For automated workflows and data integrations, prioritize platforms that offer API access like Fillout or Superhuman Docs. Check the pricing structure carefully, noting that ThesisAI starts at $14 per month without a free tier, while others offer a free option to test capabilities. Always review subscription terms, as most platforms state no refunds and some, like Fillout and Superhuman Docs, include auto-renewal features that you must manage in-app. Finally, pay attention to stated limitations, such as Readdy being intended only for evaluation or ThesisAI providing no accuracy guarantees, to ensure the tool aligns with your professional standards and production needs.
