What do you like best about Notion?I like having dynamic pages in Notion that AI can reference, which helps to share information with my team. It's clean, simple to use, and was easy for me to set up. I value the knowledge management feature for aiding with AI prompting and keeping me in the loop with what's going on in the company. Overall, I think Notion is a great tool. Review collected by and hosted on G2.com.What do you dislike about Notion?n/a Review collected by and hosted on G2.com.

What do you like best about Notion?It’s very intuitive and flexible, and the templates are really nice. I also like the Notion AI question option. Review collected by and hosted on G2.com.What do you dislike about Notion?I don’t really dislike anything about it. The only issue is that it can sometimes be too easy to make changes where I shouldn’t. For example, I occasionally end up editing pages that aren’t mine and aren’t locked.

What do you like best about Notion?I like the flexibility of Notion's system. I find it good for personal task managers and I appreciate the views. I also like Notion AI. Review collected by and hosted on G2.com.What do you dislike about Notion?I think the AI needs to be able to access automations. Also, I need the calendar to be able to group things by a date function. It does not, and I had to create a workaround to automate changing the date to text so Notion would use it for the calendar. Honestly, the initial setup was a good deal of work. I had ChatGPT help me, so I could get it to work the way I wanted. Review collected by and hosted on G2.com.

Has anyone else noticed certain words make AI agents actually listen?

Been working with AI agents for about 2 years and I keep noticing word choice matters way more than I expected. Simple example that got me thinking. "Don't do Y until X is done" works maybe \~75% of the time for me. But "Y has a dependency on X" and compliance jumps way up (well into the 90s). Same
