Can't really recommend Reddit Answers since... well, it's AI generated and not that much different than actually
using Reddit search (which, funnily enough, you have to use
from outside Reddit for it to work right because enshittification). It does however manage to cover pretty well two of the subreddit communities that should be most
useful for people going there from here: r/writing and r/eli5. Defo can't recommend it for asking anything scientific or historic, who knows how it's going to censor or bias the answers.
Conversely, have seen
people do quite good stuff – marvels level even– from Picrew for quite a few years already I think? I could swear there was an upsurge of usage of face makers like Picrew or perhaps some predecessor right when Generation VI hit the market (wow writing that makes me FEEL OLD) and the ones that were around got a
lot of improvements because of that. Am not using it
only because I'm more of a "find an actor/actress who looks like and claim that instead" person and I've had luck with that so far XD.
On tools, it's more of a programming thing so only mostly useful to verify stuff in a pinch or in batches, but
PokeAPI gets you all the statistical or mechanical data you wanted about Pokémon in the games but you feared to ask, without having to load up Bulbapedia. There's a lot of frontend already (or for Veekun's Pokédex, its original dataset) that you can load up on your phone etc..., quite useful for those who write or consult data on‑the‑go.
