What is Hintro?

During a call, Boxy Controls give you one-tap prompts: What to say next, Handle objection, Explain clearly, and Ask a good question, plus custom controls you define yourself.
Boxy answers from your own Knowledge Base of documents, quick notes, and Custom Vocabulary, so suggestions sound like your product and your playbook.

Over 500 users have processed more than 1,000 hours of live calls on Hintro.

Where Cluely wins
Cluely has a genuine free tier, an iOS app, and the broadest general-purpose scope. If your calls span classes, interviews, and meetings, one tool covers all of it. Its brand recognition also means more community content and third-party reviews to evaluate.
Where Hintro wins
Hintro is purpose-built for sales. Boxy Controls map to moments reps actually face mid-call, like objections and pricing questions, instead of generic prompting. The Knowledge Base and Custom Vocabulary keep suggestions on-product. Hinglish transcription and suggestions are unique in this category, and the entry plan at 499 INR per month is the cheapest serious option for a sales rep paying out of pocket.
