Paperchat vs CustomGPT, which is better? (2026)

Paperchat

Free plan

Paperchat is a no-code platform for building AI chatbots trained on your own data. You upload files, point it at a website URL or sitemap, or paste plain text, and Paperchat turns that material into a chatbot that answers from your content using retrieval. Compared with an enterprise focused tool like CustomGPT, its advantages are reach, simplicity, and price. The same trained bot runs on a website widget and natively across WhatsApp, Facebook Messenger, Instagram, and Telegram, and real-time human handover lets a staff member step into any live conversation. Lead capture, conversation history, and multi-tenant team workspaces are included rather than gated behind a high starting tier. Paperchat begins on a genuinely free plan with no credit card, and its paid plans scale gently. That makes it a strong fit for startups, agencies, and support teams that want capable multi-channel chat and live handover without the enterprise price tag, heavier setup, and plain text restriction that come with CustomGPT.

CustomGPT

$99/mo

CustomGPT, sometimes written CustomGPT.ai, is an enterprise leaning platform for building retrieval augmented chatbots on your own content. It is engineered for accuracy and trust: strong anti-hallucination behavior, source citations on answers, support for very large knowledge bases, more than ninety languages, a developer API, and security posture including SOC 2. It is a genuinely strong choice for larger organizations that need compliance, auditability, and the ability to ingest huge document sets. The trade-offs are cost, weight, and flexibility. Pricing starts around ninety nine dollars per month, which is high relative to most no-code rivals, the product is heavier to set up and operate, and it does not support training directly on plain text the way lighter tools do. CustomGPT is built for the enterprise end of the market rather than for a startup that wants to launch quickly on a free plan.
