Showing 8 of 8 tools
AI assistants are general-purpose chat tools you can ask to answer questions, research a topic, summarize documents, analyze data, draft text or write code. This page compares hosted assistants such as ChatGPT, Claude, Gemini, Perplexity and Copilot with open-source and self-hosted chat apps that keep your conversations on your own hardware.
How to choose an AI assistant
Start with what you will use it for most. Compare reasoning quality on your own real questions, how long a document it can read at once, whether it can search the web and show sources, and which files and apps it connects to. For teams, check admin controls, shared workspaces and whether your data is used for training on each plan.
Hosted or self-hosted
Hosted assistants are the easiest to start with and usually have the strongest models. Self-hosted chat apps let you run open models locally or connect several model providers in one interface, which helps with privacy and cost control but needs setup and maintenance. Many businesses use a hosted assistant for everyday work and a private option for sensitive data.
FAQ
Which AI assistant is best?
There is no single winner. Each leads in different areas such as writing, coding, research with sources or integration with Google or Microsoft apps. Test two or three with the tasks you actually do and compare the answers side by side.
Are free AI assistants good enough for work?
Free plans are fine for trying a tool and occasional use. Paid plans usually add stronger models, higher usage limits, file uploads and better data controls, which matter for daily business use.
Can I use an AI assistant with confidential information?
Only if the plan's data terms fit your needs. Check whether conversations are used for training, how long they are stored and who can access them, or use a self-hosted assistant for sensitive material.
