  • Summarize totals and trends in an injected dashboard
  • Keep credentials in your browser — no third-party data import

How it works

The workflow, in plain English

Before: You log into your bank. A list of 100 transactions. You export CSV, import into YNAB, manually categorize the ones it missed, wait for reports.

After: Dassi reads every transaction row directly from the bank page. At the top of your statement, a panel materializes: “Food: $423, Transport: $187, Subscriptions: $89.” A pie chart appears. Your bank didn’t build this feature. Dassi did, using the data already on screen.

Why traditional tools can’t: Budgeting apps require CSV export or API access. Dassi reads the DOM directly — no export, no integration, no sharing your credentials with a third party.

Step-by-step

  1. Open your bank statement page (while logged in).
  2. Ask dassi to read the transaction table and categorize spending.
  3. Review category assignments and correct any ambiguous merchants.
  4. Export a summary or copy the categorized list into Sheets if needed.

Example prompts to try

  • “Categorize these transactions and show a pie chart.”
  • “Flag subscriptions and list them with monthly cost.”
  • “Show total dining spend for the last 30 days.”

Tips for better results

  • Be specific about what you want injected into the page (buttons, filters, a panel, a summary, etc.).
  • If the page has multiple sections, tell dassi exactly what to focus on (e.g., “the transactions table” or “the diff for file X”).
  • Prefer safe workflows first: draft, summarize, label, and prepare — then take actions (submit, purchase) only after review.

Frequently Asked Questions

Do I need to export a CSV?

No. dassi can analyze what’s already on screen and generate an in-page summary.

Is this secure?

dassi runs as a Chrome extension. Be mindful of what you send to a model provider; you can redact fields or ask for totals-only reporting.

Can I customize categories?

Yes. Tell dassi what categories you use (e.g., “Client Meals” vs “Personal Food”) and it can re-map accordingly.
