AI agents for Instagram DMs: tools that answer on their own in 2026
Updated:
For most small businesses, SendPulse is the cheapest way to let AI answer Instagram DMs with a person ready to step in. Its ChatGPT integration comes with the Pro plan from $12 a month, and its pricing page shows no separate AI fee. If you would rather pay your AI provider directly, InstantDM runs its agent on your own OpenAI or Claude key for a flat $30.
How AI replies are billed
The price on the plan is rarely the whole cost of AI. The tools here bill it in three ways, and the model matters more than the sticker price once your account gets busy.
Included in the plan. SendPulse lists AI on its Pro plan. ManyChat includes its AI from Pro, and SleekFlow includes AI agents from its Pro plan.
Credits or messages. Chatfuel and Flowgent give each plan a monthly allowance of AI credits, and Kommo does the same per user. SetSmart charges by AI message. When the allowance runs out, you top up or the AI stops.
Your own key. InstantDM connects your own AI account, such as OpenAI or Claude, and your provider bills you for usage. Chatfuel offers the same as an option when its credits run out.
