ChaseAI Alternative: Dun

ChaseAI positions itself as AI-powered invoice collection. It uses artificial intelligence to generate and send collection messages to your clients on your behalf.

Dun takes a different approach. Instead of AI-generated communication, Dun uses a deterministic 7-stage escalation sequence. You can see exactly what will be sent at each stage before it goes out. There is no guessing about what the AI might write or how it might phrase a request for payment.

Two approaches to collections

AI-generated messages (ChaseAI): An AI writes and sends collection messages. The content varies based on the AI's interpretation of each situation. You may not know exactly what your clients will receive.

Rule-based escalation (Dun): A structured sequence of 7 emails, each increasing in urgency. You preview every message. The pattern is predictable and professional. Early stages are friendly reminders. Later stages are firm. The final stage is a formal demand letter.

When to choose ChaseAI

If you want AI to handle the writing and sending of collection messages for you, and you are comfortable with AI-generated communication going to your clients, ChaseAI's approach may appeal to you.

When to choose Dun

If you want to control exactly what gets sent and when, Dun is the better fit. Freelancers often have ongoing relationships with their clients. Sending an AI-generated message you have not reviewed can create awkward situations. Dun's rule-based approach means your communication is consistent, professional, and predictable.

Dun is $14.99/mo and free until you get paid. Connect your invoicing platform and let the escalation sequence do the work.
