General AI assistant and work platform Tested

ChatGPT

Keeps conversation, files, research, analysis, images, and reusable project context in one interface for many ordinary knowledge-work tasks.

Best for

Repeated document, spreadsheet, research, study, and drafting tasks with a retained source and human reviewer
People who benefit from moving between conversation, files, analysis, images, and follow-up without rebuilding all context

Bottom line: Start with the free tier on one repeated task, retain the source and first output, and pay only when a measured limit blocks a workflow you can already verify.

AI answer engine and research assistant Partially Tested

Perplexity

Turns open-web questions into concise answers with links that give you a faster starting point for research.

Best for

Getting oriented quickly on a current or unfamiliar topic
Finding source links before doing deeper manual research

Bottom line: Use it as a source-finding front end, not as the final authority; try the free workflow before paying for higher limits or advanced modes.
