Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Decagon you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 91 of the 101 other AI agents grade higher.
What you could not
- An AI agent, with the models and the safeguards behind it.
- An AI model answering your customers from your own help articles.
- A chatbot builder hooked into the messaging apps.
- Splitting visitors between versions and telling you which won.
What this rests on. Decagon’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
