Perplexity

Perplexity is an AI-powered search engine available on web, iOS, and Android that queries the live web in real time and returns concise answers with inline citations, allowing users to verify every claim. Unlike traditional search engines that return a list of links, Perplexity synthesises information from multiple sources into a direct answer with a follow-up question interface. Pro subscribers can select which AI model answers their query — GPT-4o, Claude, Gemini, or Perplexity's own Sonar models — and access more search capacity. Focus modes filter searches to specific sources like academic papers, Reddit, or YouTube. Perplexity is used by researchers, developers, and knowledge workers who need fast, cited answers to complex questions without manually reading through multiple web pages.

Windsurf

Windsurf is an AI-powered IDE developed by Codeium, available for Windows, Mac, and Linux, built around an agentic AI called Cascade that can read, understand, write, and execute code across an entire project — not just the currently open file. Cascade operates in Flow mode, where it plans multi-step changes, runs terminal commands, interprets test output, and explains its reasoning as it works through a task. All standard IDE features including syntax highlighting, debugging, and Git integration are included. Windsurf is compatible with most VS Code extensions. The free tier provides a generous daily AI usage allowance. It is used by developers who want an AI that can take on larger, end-to-end coding tasks with minimal manual steering, rather than providing individual line completions.
