How do I price my SaaS?

Hey PH tribe, Few weeks ago, I launched AnswerFlowAI - A Custom ChatGPT Bot Builder as a pre-launch lifetime license offer. Post-launch I'd like to go with monthly SaaS plans for both my steady MRR and also provide continuos support to our users. Since our USP is letting users use their own OpenAI API Key, we are able to provide a standard chatbot service at market-challenging price. Now, what do you guys think is a good starter price for this saas? Other similar tools cost an average of $99/month to get a good chatbot solution up and running. As we're gearing up for launch, I will have to decide and finalise the pricing 🚀 🥳 PS: Our launch page - https://www.producthunt.com/products/answerflow-ai
