The app boasts a range of powerful tools to enhance the chat experience. Users can upload images for vision-capable models or text files for any model, enriching conversations with contextual information. The integrated Web Content Reader, powered by Jina Reader, allows for the fetching and inclusion of webpage content directly into chats. For quick access, a Home Screen Widget enables instant chat initiation by snapping a photo, uploading an image, pasting clipboard text, or starting a blank conversation. The Share Extension further streamlines this by allowing users to send text or links from any app directly into 3S Chat.
A standout feature is the built-in AI Keyboard Extension, which acts as a writing assistant within any application, including iMessage, WhatsApp, and email. This extension offers customizable prompts for instant rewriting, personalized tone and style settings, and ensures no forced cloud storage, giving users control over their data. The application is optimized for iOS, iPadOS, and visionOS, providing a seamless experience across Apple devices.
User feedback highlights its utility for connecting to local LLM servers like LM Studio, with appreciation for its one-time purchase model. While some users have requested additional features like improved backgrounding and specific model grounding, the developer has been responsive, continuously adding new functionalities such as image and web content support, and iCloud sync. The app aims to provide a flexible and powerful way to engage with AI models, catering to both casual users and those who prefer to manage their own LLM infrastructure.
