Jev is a new AI tool from a ChatGPT co-creator that replaces traditional chatbot responses with rapid, structured decision-making. Instead of generating text answers, Jev takes multiple-choice style questions and returns decisions with confidence scores, making it 200x faster and 400x cheaper than standard LLMs. The article walks through practical use cases including filtering LinkedIn connections, processing Gmail, and research paper analysis.
Key Takeaways
- Jev skips text generation entirely, acting as a 'smart yes/no button' that processes decisions hundreds of times per second at a fraction of traditional LLM costs
- The tool is 200x faster and 400x cheaper than conventional chatbots like ChatGPT or Claude, with $5 in free credit that is practically impossible to exhaust
- Jev works by accepting structured MCQ-style inputs and returning decisions with confidence scores, eliminating hallucination risks from open-ended responses
- Practical applications include classifying thousands of LinkedIn connections, filtering emails, and screening research papers at scale
- Jev integrates with Claude Code and Codex via a plugin marketplace and can be connected to tools like GitHub, Vercel, and Apify for richer workflows
