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

• Live-camera-only capture
  Photos come from the phone camera at the moment of submission — no gallery uploads, no forwarded images, no old photos.
• No app or login for workers
  Workers get a text, tap a link, and take the photo — nothing to download, no account, works on any phone.
• GPS + server-set timestamps
  Every record carries GPS coordinates and a server-set time, so location and timing can't be set by the device.
• Tamper-evident chain of custody
  Each submission is sealed with a SHA-256 hash — any later edit is detectable.
• Randomized photo challenges
  The system initiates unannounced photo requests, so proof can't be staged in advance.
• Dispute-ready evidence packets
  Sealed records export as an organized packet the moment a claim or chargeback lands.
• Site proximity verification
  Submissions are checked against the job site's location, flagging photos taken elsewhere.
• AI photo review (advisory)
  Automated review flags photos that don't match the task instructions — advisory only, never blocking a submission.

• 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.
