Heatpoints VS https://open-gpt.app/

• Attention Score
  The free scanner: paste a URL, get a score out of 100 and a blurred heatmap in seconds. No account needed.
• Scan Designs & mockups
  Drop a JPG or PNG — a Lovable export, a Figma frame, a client's V1 — and score it before a single line of code ships. Same model, same metrics as a live URL.
• LiveHeat
  Not a screenshot tool: LiveHeat runs the model on your page as you use it. Four modes, one canvas — each answers a different question.
• Regions
  Draw any zone on the page — a CTA, a banner, a face — and get the exact share of predicted attention it captures. Select several zones and compare them: the A/B argument in one number.
• Scrollcast
  LiveHeat records a full scroll of your page and renders it as a saliency video: attention flowing, section after section. Export it, drop it in a client deck — it's the before/after nobody argues with.
• Scrub
  Flip Scrub on and the page scroll becomes the video timeline: you walk the attention story frame by frame, at exactly the position your visitor would be. The most natural way to review a long page.
• Words Map
  Every text block is scored twice: what it says, and whether the eye actually reads it. Not per paragraph — per word, with a 0→1 reading-attention score on each token and a verdict on each sentence.
• Multi-device audit
  Desktop, tablet and mobile captured section by section — each screen scored on attention, focus, coverage and hierarchy.
• Report Studio
  Executive summary, per-section notes, cross-device findings and priority actions — written by GLM-5.2 from your real metrics. Generated server-side: close the tab, the finished report waits in your dashboard.
• Pulse
  A cookieless snippet measures how real visitors actually behave — scroll reach, dwell, rage clicks — and confronts the prediction with reality. No banner needed.
• Badges
  Every scan ships a live badge for your README or footer, and pages scoring 80+ earn the Certified label — rare on purpose, verifiable by anyone.
• Figma plugin
  Select a frame and the attention heatmap lands on your canvas as a layer, with 4 scores (attention, focus, coverage, hierarchy). Catch hierarchy problems in design review — before dev builds anything. Pending Figma Community review.

• 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.
