Grok
xAI's assistant with real-time X (Twitter) awareness and an anything-goes persona.
Search & Research
Answer engines replaced the blue-links ritual with direct, sourced answers; deep-research assistants go further and spend minutes compiling a cited report. For academic work, systematic review tools can screen hundreds of papers in an afternoon. The skill being replaced is not reading — it's filtering.
How to choose
- Everyday questions with sources → Perplexity-class answer engines.
- Literature reviews and evidence synthesis → Elicit and Consensus read the papers for you.
- Your own documents → move to Docs & PDF tools; general search tools won't index them.
