What to look for in a free Perplexity alternative
Free tiers differ a lot from tool to tool. Check these points before you settle on one.
Cited web sources
Perplexity is built around tying answers to sources. If you need to verify what you read, favour an alternative that also shows the pages behind each reply.
Up-to-date answers
Research depends on current information. Check that the alternative can fetch recent web results instead of leaning on old training data alone.
General-purpose flexibility
You may want help with writing and reasoning as well as search. See whether the alternative also works as a capable all-round assistant beyond quick lookups.
Free-tier usage limits
Free plans cap usage and reset the limits on a schedule. Make sure the caps cover the number of questions and searches you run on a normal day.
