Best use cases

Best use cases

Customer Support Agent

Support teams handle 60-80% of tickets that are repetitive FAQs, draining agent time and creating inconsistent responses. As ticket volume scales, hiring linearly is unsustainable and new agents take weeks to ramp up on product knowledge.

Open Guide

Code Review Agent

Engineering teams spend 20-30% of their review cycle on repetitive style, security, and performance checks that could be automated. At scale, manual reviews become a bottleneck that slows deployment velocity.

Open Guide

Sales Outreach Agent

SDRs manually craft 50-100 outreach messages daily, losing context across touchpoints and spending 40% of their time on leads that will never convert. Response rates on generic templates hover at 2-3%, while personalized outreach can reach 15-20%.

Open Guide

Document Processor

Organizations process thousands of documents monthly in mixed formats (PDF, scans, emails, images). Manual classification and data extraction introduces 5-15% error rates, 2-3 day processing delays, and scales linearly with headcount.

Open Guide

Lead Qualifier

SDRs spend 40% of their time on leads that never convert. Manual qualification is inconsistent across reps, high-value leads get delayed in queue, and scoring criteria evolve faster than spreadsheet-based models can keep up.

Open Guide

Email Automation Agent

Email teams handle 200-500 messages daily with repetitive follow-ups and inbox spikes around product launches and incidents. Average response time stretches to 6-12 hours, while customers expect replies within 1 hour.
