The AI comes ready
No API key, no model to pick and no second bill from an AI provider. Add your website and documents and the agent starts answering.
Comparison
SimplyBoostvs InstantDM.
SimplyBoost does what InstantDM does, with the AI already built in. Comment-to-DM rules send your link with a public reply, a follow request and follow-ups, and an AI agent trained on your website and documents answers Instagram DMs on every plan, with no API key to bring and no flow to build.
Our Verdict
SimplyBoost is the better choice for AI in your Instagram DMs. InstantDM's AI agent sits inside a flow and runs on an API key you bring and pay for. SimplyBoost's agent is included on every plan, learns from your website and documents, and answers without a flow to build, with a hand-off to your helpdesk, the same agent on WhatsApp and your website, and hosting in Europe.
One comment, start to finish.
The keyword triggers the DM with your link. When the person asks something your DM didn't cover, the AI agent answers from your own website and documents, with no flow to build for it.
