ChatGPT
ChatGPT is OpenAI's general-purpose AI assistant, available through the web, desktop apps and mobile. It handles everyday tasks like drafting and editing text, answering research questions, summarising documents, writing and debugging code, and brainstorming. The free tier runs on a smaller model with usage limits; paid plans unlock the latest models, higher message caps, image generation, file uploads and custom GPTs. A voice mode allows spoken conversation, and the API lets developers build ChatGPT-style features into their own products. It is the default starting point for most people new to AI, and remains a strong all-rounder for writing and coding alike.
Ollama
Ollama lets you run open-weight language models on your own machine with a single command. It handles model downloads, GPU acceleration and local serving, exposing an API compatible with common OpenAI-style clients. The library includes models for chat, coding, vision and embeddings, from laptop-friendly options to larger models for workstations. Because everything runs locally, prompts and data never leave your computer — useful for confidential work, offline use and experimentation without per-token costs. It runs on macOS, Linux and Windows, and integrates with tools like Open WebUI. It is the simplest way to start with local LLMs, though large models need substantial RAM and a capable GPU.
Perplexity
Perplexity is an AI answer engine that responds to questions with a synthesised answer and inline citations to the sources it used. Instead of a list of links, you get a short, readable summary you can verify by clicking through to the underlying pages. It supports focused modes for academic papers, news and community discussions, and Pro search runs multiple follow-up queries for deeper research. Free users get a limited number of Pro searches per day; the paid plan raises limits and adds stronger models. Collections let you save and share research threads. It is most useful for fact-finding, market research and anything where you need to check where an answer came from.
