AI Chat Assistants: how to choose a tool
Short answer General advice
The choice turns on which account the assistant should reach, who else receives what you type, whether the question depends on current facts, and how much you expect to use it. Then give two assistants the same task you can check yourself and compare the answers with a source.
First, separate the job
General adviceA chat assistant answers questions and drafts text in a conversation. Researching with cited sources, summarizing a long document or building an app are separate jobs, and an assistant that suits chat may handle them differently. Answers read fluently whether or not they are right, so judge them against a source you trust, not by tone.
Questions to decide
Tools under each question come from our dated records of official pages, not tests.
Which account and data should the assistant reach?
- Why it matters
- Personal chat and work features can be different products with different data access. An assistant tied to your company or Drive files may see more than you intend, or less than you expect.
- How to check on the official page
- Find which account type the feature needs, whether company or file access sits behind a separate licence or a permissions setting, and what your organization allows.
According to our records · checked
Microsoft Copilot · Website
Personal use with a Microsoft account and work features in the Microsoft business suite are different products; company data needs the work licence and the right account.

Google Gemini · Website
For Drive material, confirm Connected Apps permissions and organizational settings first; the record also says file analysis needs a signed-in account.

Who else receives what you type?
- Why it matters
- Some services pass conversations on to model providers or to the makers of third-party bots, and settings decide what is kept. Treat pasted text as shared until the policy says otherwise.
- How to check on the official page
- Read the privacy policy and the data controls in the account for storage, sharing with developers and any opt-out; keep confidential text out until you have.
According to our records · checked
Poe · Website
The policy says bot developers and model providers receive details of your interactions, including chat text and uploaded files, and that some developers may store chats to train their models.

ChatGPT · Website
The record advises reviewing data controls and workspace policy before pasting sensitive material; the help site has a privacy center.

Does your question depend on current facts?
- Why it matters
- A fluent answer about recent events can be out of date, or drawn from posts rather than primary sources.
- How to check on the official page
- See whether web search is on by default or a switch, whether the answer links its sources, and open the original pages yourself for anything you will repeat.
According to our records · checked
Grok · Website
For news questions it can draw on X and web search; the record says a post on X is a claim, not a primary source, so open the original.
Source: docs.x.ai/grok/overview and docs.x.ai/grok/faq ·
ChatGPT · Website
For current facts the record advises asking for web sources and opening the original pages yourself.

How much will you use it?
- Why it matters
- Free access is usually limited by messages, searches or a shared allowance, and heavy tasks use it up faster than short questions.
- How to check on the official page
- Read the plan page for how limits are counted, what resets and when, and whether heavy features draw from the same allowance as chat.
According to our records · checked
Mistral Vibe · Website
The Free plan gives limited messages, web searches and coding sessions; the paid plan raises them, and the record advises upgrading when you hit the limits.
Source: mistral.ai/pricing ·
Grok · Website
Usage is one shared weekly allowance across Grok products, so long video or coding tasks use it up faster than chat; the free allowance is not stated on the pages reviewed.
Source: docs.x.ai/grok/faq and docs.x.ai/grok/overview ·
Limits
According to our records · checked
Claude: Non-PDF document uploads are processed as text, so embedded images may be missed; access and usage depend on plan, location and changing limits.
Source: support.claude.com/en/articles/8241126-upload-files-to-claude ·
DeepSeek: The chat sign-in page could not be opened during review, so sign-in requirements and free chat limits are unverified; developer API prices are separate and can change.
Source: www.deepseek.com/en/ and api-docs.deepseek.com/quick_start/pricing ·
Poe: The terms say bots may not give accurate information and offer no warranty; bots run under different conditions, so a result from one does not carry over to another.
Source: poe.com/tos ·
Microsoft Copilot: Sign-in is required and there is no anonymous chat; do not plan around a feature the page labels as a preview.

A first try
General advice- Choose a task you can check yourself: a paragraph to rewrite, a question whose answer you know, or a short draft built from facts you supply.
- Give the same task to two assistants that fit your answers, on the plan you would use, and compare accuracy, tone and what each asks to see.
- Open the source of any fact you will repeat, and keep confidential text out until you have read the privacy settings.
If nothing fits

Notes that apply to several tools
- Check the official page for current quotas and output conditions.
- Check each tool’s plan separately; one feature’s allowance does not cover another.
- Check AI answers against their sources. Review account permissions and data settings before sharing private files or connections.
