kasipa (formerly deepsheet) vs PromptLoop

kasipa (formerly deepsheet) turns CSV, Excel, or Google Sheets into interactive Plotly charts when you ask questions in plain English. Upload a spreadsheet or paste a Google Sheets link, describe the chart you want, and refine the result with follow-up messages until it matches what you need.

Unlike cloud analytics suites that upload your files to remote servers, kasipa runs spreadsheet parsing and chart generation locally in the browser via WebAssembly. That local-first approach suits quick one-off visualizations where you do not want data leaving your device, though team database connections and shared Explores sit behind the paid Professional tier.

You can start charting without creating an account, and multi-sheet Excel workbooks let you pick which tab to visualize. kasipa also hosts a community showcase where users publish charts built from public-interest datasets, plus dedicated CSV and Excel to chart landing pages for fast uploads.

Creator Dylan Castillo built kasipa for analysts, researchers, and business users who want spreadsheet insights without writing code or juggling separate charting tools.

Upload a CSV or Excel file with company names or URLs, tell PromptLoop what data you need, and AI agents crawl the web to fill new columns in your dataset. The platform targets go-to-market teams who want prospect lists enriched with live web signals rather than hand-researched one row at a time. Results land back in a filterable workspace you can export or sync to HubSpot and Salesforce.

Most Excel AI tools generate formulas or analyze cells you already have. PromptLoop treats each row as a research job instead. Its agents browse live sites with configurable crawl depth, return structured fields like phone numbers or pricing signals, and scale from a single test row to 50,000 inputs per job. That workflow sits closer to Clay-style list enrichment than a copilot inside one spreadsheet cell.

Growth, sales, and revenue teams use PromptLoop to qualify outbound targets, scrape competitor pages at scale, and push enriched records into HubSpot or Salesforce. Customers listed on the site include BCG, Arketa, and Kinside. Excel and Google Sheets integrations remain available for teams that want formula-style access alongside the main dataset builder.
