No Installation Required
Being a web application, it can be used directly from a browser without downloading or installing any software.
Potentially Free or Low-Cost Access
Many GPT wrapper sites like this offer free tiers or lower-cost access compared to official API pricing, making AI chat more accessible to casual users.

Possible disadvantages

Uncertain Reliability
Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
Data Privacy Concerns
Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
Limited Transparency
It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
Potential Hidden Costs or Ads
Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
Lack of Official Support
Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.

Questions & Answers

As answered by people managing https://open-gpt.app/ and Exarbi.

Who are some of the biggest customers of your product?

Exarbi's answer:

Customer names are not publicly disclosed.

What makes your product unique?

Exarbi's answer:

Exarbi combines live cross-exchange arbitrage monitoring with transfer-readiness and risk signals in one multilingual interface. It helps users evaluate not only price differences, but also factors such as network compatibility and deposit or withdrawal availability. Exarbi does not require exchange API keys, does not execute trades on behalf of users, and does not hold user funds.

Why should a person choose your product over its competitors?

Exarbi's answer:

Exarbi is designed for users who want decision-support rather than an automated trading bot. It provides a clearer view of cross-exchange opportunities while highlighting operational conditions that can affect whether an arbitrage opportunity is actually usable. Users can review market and transfer signals without giving the platform exchange API access or custody of their funds.

How would you describe the primary audience of your product?

Exarbi's answer:

Exarbi is primarily built for crypto traders, arbitrage researchers, market analysts, and advanced retail users who compare prices across exchanges and want to evaluate transfer conditions before making their own trading decisions. It is also useful for users who prefer a non-custodial monitoring tool instead of automated trade execution.

What's the story behind your product?

Exarbi's answer:

Exarbi was created to make crypto arbitrage data easier to understand and evaluate. Price differences alone are often misleading because transfer networks, deposit and withdrawal status, fees, liquidity, and timing can affect whether an opportunity is practical. Exarbi brings these signals together in one interface so users can make more informed decisions without handing over exchange API keys or control of their funds.

Which are the primary technologies used for building your product?

Exarbi's answer:

Exarbi is built with Next.js and TypeScript using the App Router architecture. Its stack also includes Prisma for data access, server-side authentication and protected routes, Stripe for subscription payments, Resend for transactional email, GA4 for consent-aware analytics, Tawk.to for customer support, and Nginx for production delivery and reverse proxying.
