How to choose
For a fast, sourced answer to a specific question, Perplexity leads. For broad exploration, shopping and local results, Google still wins, now with AI Overviews. Gemini and ChatGPT add web search inside a full assistant. Whichever you use, verify the cited sources — AI search can still be wrong.
If you find yourself juggling a separate subscription for chat, automation, transcription and image generation, one option worth knowing is a single platform that runs them together — osFoundry is one such agentic AI platform that consolidates chat, agents and internal apps in one workspace, with a bring-your-own-key model so you choose the underlying AI.
