In their own words
PromptLoop
PromptLoop helps sales and go-to-market teams research and qualify prospects by extracting company data, buying signals, and custom insights from websites. Its no-code AI tasks accept website lists or search terms and return structured data, strict formats, and confidence scores. Website tasks crawl supplied URLs; search tasks find a name or keyword and then crawl relevant pages. Managed tasks can create or transform AI columns and return verified or probable work emails and phone numbers with related metadata. PromptLoop documents HubSpot and Salesforce integrations for importing company lists and syncing selected results to CRM records. Its functions and tasks work with Excel and Google Sheets, and a REST API connects existing systems. Credit use varies: normal outputs cost one credit per row or website, list outputs cost one credit per returned row, and returned emails and phones cost 5 and 50 credits respectively. Tasks with more than six output items may run slower or lose accuracy; chained workflows support up to five steps. The Free plan has 500 credits, one seat, and 25 rows or inputs at a time.
Quadratic
Quadratic is an AI-enabled spreadsheet that combines spreadsheet formulas with Python, SQL, JavaScript, live data connections and AI. Users can ask questions in plain English, then inspect and edit the formulas, code and charts AI generates in spreadsheet cells. It imports CSV, Excel, Parquet, PDF and Google Sheets files, and connects to sources including PostgreSQL, Snowflake, BigQuery, QuickBooks, Google Analytics, Mixpanel, Plaid and Salesforce. Quadratic says a sheet can hold 100 million rows and can import multi-GB CSV and Parquet files. Its MCP server lets compatible AI tools read sheets, write cells and charts, and run Python, SQL and formulas; an API can trigger AI runs and read or write cells. Quadratic says data is stored and calculations run on the user's computer by default, and that its cloud service is SOC 2 and HIPAA compliant. Desktop apps are available for macOS and Windows, with a mobile UI for phones. Personal is free with limits; Pro costs $18.00 per month, billed annually.
