Many investors already use a general AI assistant to read research material. Upload an annual report and ask for the risk factors, paste a transcript and ask what changed in guidance, or ask for a plain explanation of a term in a filing. These assistants are flexible and cheap compared with professional platforms.
They are also the tools most likely to get a number wrong. A general assistant may read the wrong period, misread a table, confuse two companies with similar names or fill a gap with a plausible guess. Some can search the web, and their answers depend on which pages they find. Treat every figure as unverified until you have found it in the source document yourself.
Good habits help. Give the assistant the document instead of asking it to recall facts, ask it to quote the passage behind each answer, and ask for the page or section so you can check it. Use it to organize questions and drafts, not to make decisions.
Think about what you upload. Check each assistant's data settings, such as whether chats are used for training and how long files are kept, before sharing anything private, such as client portfolios or account statements.
A simple routine works well. Upload the filing or transcript, ask the assistant to list the main points with section references, and then read those sections yourself. Ask follow-up questions about what changed from the previous period, and paste in both documents so it compares the right texts.

Microsoft's consumer assistant for chat and web answers, built into Windows and Edge.
AI search engine that answers questions with numbered citations to the pages it used.
Watch for dates. Assistants without web access may not know about recent results, and those with web access may pick up old articles or forum posts. Ask the assistant to state the date of each source it used, and check that the period matches the one you care about.
Numbers in tables are the weak spot. When you need figures from a financial statement, ask the assistant to copy the table exactly, then compare a few rows with the filing before you work with it.
Keep the output in your own words. Notes written by an assistant can sound more certain than the evidence allows. Rewrite the conclusions yourself and keep the links to the source passages beside them. If you work with client information, ask your employer which tools are approved before uploading anything.
Nothing on this page is investment advice, and these assistants don't give it either, whatever they say. They don't know your situation, and they can be confidently wrong.
You can, but the answer isn't advice from someone who knows your situation, and it may rest on wrong or outdated facts. Use assistants to read and organize research, and make decisions with your own checks or a licensed adviser.
Give it the document, ask it to quote the exact passage behind each figure and check those passages yourself. Answers recalled from the model's memory are the most likely to be wrong.
Check the assistant's data settings first, including training use and retention, and remove account numbers and personal details you don't need to share.
Accuracy varies with the document and the question. Try the same filing and questions in two assistants, and compare their answers against the source before you settle on one.
