I think it would be great for both products if they were integrated tightly. The chat features in quip are barely used because they’re so anemic, and Slack is missing a document catalog UI, and, in a way, has gone to war with document catalogs because it wants chat to be the “center” of work. But this is often a mismatch for customers who view both as equally important.
At my job we use Quip strictly for collaborative design docs (i.e. architectural design, project scope, tutorials etc). Personally I don't think it can be a true wiki platform since it lacks robust indexing -- this is without doubt its biggest shortcoming.
Correct. Quip is not a wiki. I would call it an “opinionated and stripped-down version of GSuite with excellent collaboration support”. Quip also has chat stapled to it.
Slack is missing doc management/creation. Quip is missing a good chat solution. It’s almost like PB&J.
