Your AI Is Brilliant — Until You Hand It a Bank Statement.
Pennyweight fixes that: a memory that persists, and your finances fed to it organized, categorized, and current — pieces it can actually reason over. The AI you already use, finally smart about your money.
6 months free. No credit card needed.
Ask, don’t click.
No more guessing which expense belongs where. Ask real questions across every entity, get answers that actually separate your lives.
Ask, don’t click
No dashboards to learn. Ask questions about your money in plain English and get answers instantly, inside the AI tool you already use.
Built for AI
Designed for the AI you already use — Claude, ChatGPT, Gemini, Grok, or any MCP client — from the ground up, not a chatbot bolted onto an old product. Pennyweight gives your AI a memory that persists between chats and context it can actually reason over, so it generates the reports you need.
Encrypted with your passphrase
Your passphrase derives an encryption key in your browser, and your data is encrypted with it. A stolen copy of our database is unreadable. Our servers decrypt only during your session, to answer your questions and sync your bank.
Three steps. That’s it.
No software to install. No spreadsheets to set up. Connect and ask.
- 01
Connect Pennyweight
Add Pennyweight as a custom connector in the AI you already use — Claude, ChatGPT, Gemini, Grok, or any MCP client — by pasting one link. Then link your bank through Plaid.
- 02
Your data flows in
Your bank pushes new transactions as they post; they land in your encrypted ledger the next time you open Pennyweight or ask your AI. Pennyweight helps you categorize everything in minutes — drafting rules that learn your patterns.
- 03
Ask anything
Ask your AI for a P&L, a tax summary, a category breakdown, per entity or across all of them. Real answers, instantly.
Get early access.
We’re building this for people whose financial life doesn’t fit in one bucket.
6 months free — then $7.99/mo or $69.99/yr, USD. No catch.
