Hello @sanjeev n
I was wondering about this for the last 2 years, even before they launched Product Tours but announced it during one Intercom event.
Since then some time passed and it was finally live. I had high hopes for it as back at that time I've been already dealing with other Digital Adoption Platforms and since Intercom was already used I thought it would be great to migrate everything to Intercom. But realized that Product Tours is pretty basic compared to what I needed back then. So we did not go with Product Tours.
However, Product Tours is a great tool to start with especially if you are already using Intercom heavily. I like how it can be integrated into other features like chat and Series.
What it lacks is better options for styling (as does Intercom in general). It does not have any advanced triggering options, no advanced logic.
If you need complex user tours, with a lot of logic, branching, Intercom Product Tours is not for you.
Will Intercom improve Product Tours? Probably yes, but I highly doubt that it will be competing with real DAP any time soon, maybe if Intercom acquires one of the smaller DAP players.
BTW, with the help of some devs, you can simulate the checklist (dev can create a menu with links to product tours and can track who clicked on it and put a checkmark if it is clicked). I've worked on cases where devs even took over the logic and they were launching different Tours I made based on the activity of the user on the page and thus creating the one longer Tour, like it had a capability to branch.
