How to Analyze Your Personal Finances Using the Perplexity Comet AI Browser Extension

Use a browser assistant to summarize information already visible in a financial account, while keeping login and transaction control with the user and independently checking balances, dates, fees, tax lots, and calculations before acting.

How to Analyze Your Personal Finances Using the Perplexity Comet AI Browser Extension

Anish describes opening a financial site in Comet and asking the browser assistant how his portfolio is performing, using the page context to make a complex website easier to understand through natural language questions.

Before you start

What you need

  • A supported financial site and an account with strong multifactor authentication
  • A clear read only question and the exact period, benchmark, and account scope
  • The institution's statements or exports for independent comparison
  • A privacy decision about what the browser assistant may read and retain
  • A qualified financial or tax professional when the question affects consequential decisions

What you’ll make

A read only portfolio summary with the selected date range, calculation method, source values, limitations, and discrepancies clearly identified, without trades, transfers, credential sharing, or personalized recommendations executed by the assistant.

Tools used

Step by step

The workflow

Follow the sequence once, then adapt the prompts, checks, and handoffs to your own setup.

4 steps

Step01

Install the Comet Browser Extension

Review Comet's current permissions, data use, retention, and site support. Secure the financial account with multifactor authentication and decide which pages and fields the assistant may read. Keep transaction permissions out of scope.

Step02

Navigate to Your Financial Platform

Log in through the financial institution yourself and navigate to the exact account and period. Do not paste passwords, recovery codes, full account numbers, or tax identifiers into the assistant.

Step03

Use Comet to Log In and Analyze

Ask a narrowly defined read only question and require the assistant to show the displayed values and formula behind its answer. Start with description and reconciliation, not investment advice.

Example prompt
Using only the information visible on this page, summarize the performance of [account scope] from [start date] to [end date]. Show beginning value, ending value, deposits, withdrawals, dividends, fees, currency, and calculation method. Compare with [benchmark] only if matching period data is present. Cite the page section for every figure. Do not trade, transfer, or recommend a security.
Step04

Ask for Financial Insights

Compare balances and calculations with the institution's statement or export. Investigate discrepancies, note missing data and stale prices, and take consequential financial or tax questions to a qualified professional.

Example prompt
Give me an analysis of my portfolio.

What good looks like

  • The assistant never receives a password, recovery code, or permission to trade or transfer funds.
  • Performance calculations state account scope, cash flows, fees, dividends, dates, currency, and benchmark.
  • Balances and material figures match the institution's statement or export.
  • The output separates factual account description from market interpretation and financial or tax advice.

Recover

If it goes sideways

The assistant asks for credentials, recovery codes, or broader account permissions
Stop, use the site's normal login and multifactor flow yourself, and restrict the assistant to approved read only page context.
The reported return ignores deposits, withdrawals, fees, dividends, currency, or the selected date range
Request the exact formula and source values, then compare them with the official statement or export.
A summary drifts into a trade, transfer, or high stakes personalized recommendation
Do not authorize transactions, and review consequential investment or tax decisions with a qualified professional.
Sensitive balances, account numbers, or tax information are retained or exposed unnecessarily
Limit visible pages and fields, redact exports, review provider retention controls, and remove stored sessions or data when supported.
