Abelo 10 features
  • Accessible AI Chat Interface
    Provides a user-friendly web-based interface for interacting with GPT-based AI models without needing to set up API access or coding knowledge.
  • 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.
  • Quick Setup
    Users can typically start chatting almost immediately after visiting the site, with minimal account creation or configuration steps.
  • Cross-Platform Compatibility
    Since it runs in a browser, it can be accessed from various devices including desktops, tablets, and smartphones without platform-specific versions.

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.
  • Viber & WhatsApp campaigns
    Reach customers where they actually read — chat apps hit up to 98% open rates vs. 18% for email, so your offers get seen instead of buried.

  • 1:1 message personalization
    Customer names, tailored discounts, and product recommendations make every message feel handwritten — not mass-blasted.

    Set-and-forget flows for post-purchase upsells, win-backs, and back-in-stock alerts that sell 24/7 with zero manual effort.
  • Real-time ROI attribution

Questions & Answers

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

What makes your product unique?

Abelo's answer:

VibeCart is the first sales and marketing platform built specifically for selling on Viber and WhatsApp — the channels where Southeast European shoppers actually live. Most tools treat chat as an add-on to email; VibeCart is chat-native. It reads your store data in real time and acts as an autonomous sales agent, automatically running cart recovery, product launches, and personalized campaigns that convert 5–10x better than email or SMS. AI generates the copy and visuals, and every order is attributed in real time — so it does the work of a full marketing team with zero manual effort.

Why should a person choose your product over its competitors?

Abelo's answer:

Channel, automation, and proof. Competitors push email and SMS — channels with ~18% open rates and rising fatigue. VibeCart puts you on Viber and WhatsApp, where open rates reach 98% and messages actually get read. It's autonomous: AI writes the copy, segments your audience, and runs flows on autopilot, so you don't need a copywriter, designer, or extra staff. And every euro is tracked — real-time ROI attribution shows exactly what your marketing earns, so you never have to guess. It's purpose-built for Greece and Southeast Europe, not a US tool awkwardly translated.

How would you describe the primary audience of your product?

Abelo's answer:

Small and mid-sized e-commerce stores in Greece and Southeast Europe (Bulgaria, Serbia, Romania) running on Shopify, WooCommerce, or Magento — merchants whose customers use Viber and WhatsApp daily but who are stuck with email and SMS tools that under-deliver. Typically store owners and marketing leads who want more revenue without hiring more people, across fashion, health & beauty, electronics, home & garden, pharmacy, pet supplies, food & beverage, and more.

What's the story behind your product?

Abelo's answer:

VibeCart was born from a clear gap. Across Southeast Europe, 110,000+ e-shops rely on Viber as the everyday way they reach customers — yet every marketing tool on the market ignored it, forcing merchants into email and SMS that shoppers tune out. Built by Trebbble, an Athens-based product company, VibeCart set out to turn the region's favorite chat apps into a 24/7 revenue engine for online stores — giving local merchants an autonomous, AI-powered sales agent that levels the playing field with the big players. The mission starts in Greece and expands across the Balkans.

Which are the primary technologies used for building your product?

Abelo's answer:

VibeCart integrates with the Viber Business Messages API and the WhatsApp Business Platform (Cloud API), connects to e-commerce platforms via the Shopify, WooCommerce, and Magento APIs (plus custom platforms via API), and uses AI/LLMs for campaign copy and image generation. Core stack is GCP.
