PrompLoop

Extracts B2B data from websites in minutes

PromptLoop is an AI platform that automates B2B research and data enrichment for sales and marketing teams. It extracts company information from websites, processes large datasets in spreadsheets, and integrates with tools like HubSpot.

The core functionality centers on AI agents that crawl multiple pages per site and apply custom models to verify and format data. Users input URLs or search terms into Google Sheets or Excel, where formulas like =PROMPTLOOP.INFERENCE trigger tasks such as summarization or classification. Deep Research processes up to 50,000 rows simultaneously in higher plans, maintaining consistent outputs with version control. Custom AI models train on sample data without coding, supporting tasks like lead qualification or SEO tagging.

PromptLoop uses dozens of AI models, including proprietary ones updated weekly, for 90 percent accuracy in extractions. It outperforms ChatGPT and Claude in multi-page handling and sourcing, as shown in its comparison table. Competitors include Clay, which offers similar enrichment but requires more configuration, and Numerous.ai, focused on formula automation rather than web scraping. PromptLoops free plan provides 100 credits for trials, while paid tiers scale affordably compared to agency services, often reducing costs by 85 percent.

Users appreciate the speed of setup and one-click CRM syncs, which save hours on manual entry. The Geographic Search filters results by location, and Phone + Email Enrichments add contact details reliably. Potential drawbacks include credit limits on free use and occasional inaccuracies in complex prompts, requiring retraining. A surprise element is the Web API, enabling seamless ties to existing systems for automated workflows.

Integrations extend to REST APIs for custom connections, supporting unlimited exports across plans. Technical specs include cloud-based browsers for global access and strict formatting to match user schemas. For teams handling GTM data, it provides enterprise-grade scale without added complexity.

Test PromptLoop on a small dataset first, refine prompts based on outputs, and integrate with your CRM early to maximize efficiency in daily research.
