CinderReal-time AI coaching for every call. No bot on the line.

Built for professionals who live on calls.
Real-time sales coaching
Real-time sales call coaching gives a rep guidance during a live call instead of feedback after it ends. Cinder does this on Mac by listening to your call audio and showing short, specific prompts as the conversation happens: the next question to ask, how to handle the objection on the table, and the buying signals worth chasing.
Unlike post-call tools that score a call after it is over, and unlike notetaker bots that join the meeting, Cinder runs quietly on your machine and never appears in the call.
Cinder reads your call through Mac system audio. No bot joins, no plugin, no link to paste.
As you talk, it surfaces the next move, the objection you have not handled yet, and signals worth chasing.
After the call you get a summary, action items, and a follow-up draft you can send.

Categories reflect each product's public positioning. Tools like Gong and Chorus lead the post-call category, which is a different job from coaching you during the call.
Real-time sales call coaching gives a rep guidance during a live call instead of feedback after it ends. As the conversation happens, the tool surfaces the next question to ask, how to handle the objection on the table, and the buying signals worth chasing.
Post-call tools score and summarize a call after it is over, which is useful for review but cannot change the call you are on. Real-time coaching helps you during the conversation, while you can still act on it.
