Heuristica is based on ChatGPT. It allows the user to interact with ChatGPT by simply pressing buttons instead of writing lengthy prompts. Heuristica takes care of obtaining information from the AI so that you can focus on exploring and learning new things.

A chat-based interface can only support a linear flow of information. Heuristica leverages a node-based user interface (UI) to support non-linear and visual learning. This way, you can explore a subject differently and learn unexpected things. Heuristica helps you interact with ChatGPT by simply clicking buttons, saving you time. It doesn't require any prompting knowledge.

With a professional subscription, you can take advantage of many valuable features like having access to more capable models like GPT-4, editing capabilities, writing custom prompts, taking advantage of integrations with Semantic Scholar, Arxiv, search news, podcasts, or YouTube videos, taking advantage of premium prompts like generating social media posts, etc. See some of our newly added features at https://www.heuristi.ca/docs/changelog

You can cancel your subscription at any time. It is not a long-term commitment. You will only be charged for the current month (or the year if it is an annual subscription). To manage your subscription, click the Subscription button in the header or footer. This button is only visible to subscribed users.

Sometimes, you notice that features are still locked even if you purchase a subscription. The most common reason for this problem is that the email address used for purchase differs from the email address registered on the website. You can fix this issue by updating your primary email address on the site by clicking your user avatar and selecting Manage Account.

You can use the Subscription button at the bottom of the landing page to manage your subscription and download your invoice. This button is only visible to subscribed users.
