Open-source platform for conversational AI agents.4,08710Released 16d agoFrom $10We use this tool for lead qualification in real estate, and it’s been a huge win.

Create AI voice agents for automated calls in seconds.3,88446Released 1y agoFrom $37/moCallfluent is NOT ready for commercial use. I signed up, followed their tutorials to a tee, and could not get voice bot to work. The bot would hallucinate about dates, and would actually argue with me about days dates. I tried to connect with their support, and kept getting the same replies -- to not use the web based calling feature. I was actually calling by phone to test the bot. Support is TONE DEAF. I sent call recordings, transcriptions, and detailed list of issues by email. They kept repeating the same answers... almost as if they use their own garbage AI for tech support. I requested a ZOOM call with their "onboarding specialist" and was given access to a calendar, with the soonest appointment 8 days away. I requested a sooner appointment and the specialist started offering me times IN THE PAST. Again, I think they use their own AI for support or scheduling. I would stay away from this product. Not very good at all. Avoid at all costs if you wish to have a successful AI chat and voice bot. -
