Perplexity is an AI answer engine, best known for answering questions from the web with linked sources. Flash ∞ AI is an all-in-one AI workspace: you type what you want, and Flash sends each request to the AI model that does that job best.
If you mainly want fast answers with sources and nothing more, Perplexity is built just for that.
Flash is free to start, with credits every month and no card needed, so you can compare with your own work.
