Let your assistant do the rate research.
Give it a deposit amount and what matters to you. RateZip supplies observed savings and CD rates, with sources and dates, so your assistant has a clearer starting point.
Published rate research. Final terms and eligibility come from the institution.

Choose your connection.
Custom connection
Gemini Spark
If your Gemini account offers Custom apps, add RateZip from the Gemini web app:
- Open Settings → Connected apps.
- Choose Custom apps → Add custom app.
- Paste the server URL below and follow the prompts.
Google supports custom MCP connections. RateZip's connection in Gemini still needs a completed end-to-end pilot test.
Browser research
Other assistants
For an assistant that can browse, including Muse, Grok or a dot, paste the research prompt with RateZip's Rate Index link. The assistant can read published comparisons and follow sources; tool access depends on its platform and setup.

This is a tool connection address, not a webpage. RateZip's public rate lookup connection requires no RateZip login.
Make it specific
A better starting prompt.
Ask for rates that reflect your balance and requirements. Tell your assistant to show unknown terms instead of assuming an account qualifies.
RateZip covers a selection of published products. Available information varies by institution. Your assistant may need to visit a bank's own page to finish the comparison.
See how RateZip gets its data →Your research prompt
Use RateZip to compare published savings account rates for a $25,000 deposit over 12 months. I want no monthly maintenance fee without a conditional waiver. I want the stated APY without direct deposit. Apply the appropriate balance tier. Show the source and observation date, published requirements, known conflicts and anything unverified. Do not treat missing terms as a match or claim eligibility. Estimate gross interest only if the APY applies, stating all assumptions; for CDs, use only the requested term without assuming renewal. Check access restrictions and other APY conditions. If you cannot connect to RateZip, use https://www.ratezip.com/rate-index and explain which checks still require the institution's own page.
This form builds text in your browser. Paste the prompt into your connected assistant to begin the research.
What your comparison should show
- The APY for your balance and any tier conditions.
- The source, observation date and older-data flags.
- Fees and requirements that are known or unverified.
- Illustrative gross interest, with assumptions explained.
Keep the final check with the institution
Published rates can change. Check opening eligibility, membership, promotional conditions, access limits and any fees. RateZip provides factual comparisons and cannot open an account or submit an application.
This research flow focuses on deposits. Customer-specific loan offers and insurance quotes require separate provider integrations.
