Julius analyses research data using natural language queries.

PerplexityFree
AI search with real-time web access

Search with AI that actually cites its sources. Every answer comes with numbered references you can click through — no more wondering where the statistic came from or whether it was invented. Best for research, fact-checking, and staying current on fast-moving topics where accuracy matters more than creative flair.

Deep reasoning & long-context chat

Anthropic's AI assistant — the one most often cited by professionals who care about depth. Exceptional at long-document analysis, nuanced conversation, research synthesis, and tasks requiring genuine reasoning rather than pattern-matched confidence. Widely used by writers, analysts, lawyers, and engineers who need an assistant that's careful, not just fast.

AI research assistant for academics

Search and summarise academic papers, extract key findings into structured tables, and trace every claim back to its source.

The honest way to do an AI-assisted literature review.

The world's most-used AI chat

The tool that made AI assistants mainstream — and still the most broadly capable for everyday use. Best-in-class for general knowledge, coding, content drafting, data analysis, and image generation via DALL·E 3. Four years of model improvement and a vast plugin and GPT ecosystem give it a feature lead that's hard to catch up to.

Self-organising AI notes
