Common questions

Is Boost.ai better than CustomGPT.ai for a small business?

No. CustomGPT.ai is better for small businesses because it's cheaper, faster to set up, and doesn't require a dedicated AI team. Boost.ai is overkill unless you have thousands of daily customer interactions and a compliance team.

Can I use CustomGPT.ai on my phone?

Not as a standalone app — there's no mobile app. But you can embed the chatbot on your mobile website or use it in a browser, so it works on your phone that way.

Which tool is easier for a non-technical person?

CustomGPT.ai is much easier. You just upload documents or a website URL, and it builds the chatbot. Boost.ai requires you to map out 'intents' and train the AI manually, which is technical work.

Does Boost.ai have a free trial?

Boost.ai does not publicly offer a free trial. You have to contact their sales team for a demo. CustomGPT.ai offers a 7-day free trial with no credit card required.

Which tool is better for handling phone calls?

Boost.ai is better because it supports voice input and output via SIP/RTP telephony connectors. CustomGPT.ai only handles text and code, so it cannot answer phone calls.

Can I connect these tools to my existing software like Salesforce or Slack?

CustomGPT.ai offers pre-built integrations with Google Drive, Notion, Confluence, and a RAG API for custom connections. Boost.ai has an 'Action' builder for API integrations but requires more technical setup and doesn't list common app integrations.

CustomGPT.ai wins for everyday users: it's cheaper, faster, and easier, while Boost.ai is only for big enterprises with deep pockets and dedicated AI teams.

For almost everyone reading this, start with CustomGPT.ai. It's affordable, you can try it free for a week, and you'll have a working chatbot in under an hour. Only look at Boost.ai if you're running a massive customer support operation and have a budget and team to match.
