What is Capit?
Capit is a freemium app developed by Swift Fox Software LLC, currently supporting only iPhone, iPad, and Mac devices. Powered by OpenAI’s GPT-4V multimodal model, it can “see” and interpret image content, generating high-quality social media captions in real time. Users simply choose an image, set their desired tone, and receive five ready-to-post caption options with one tap. Additionally, Capit allows users to save frequently used settings as multi-account profiles, bookmark favorite captions, intelligently insert spaces and timestamps, create more precise, lower-competition hashtags, and directly access the app via the system’s share menu from photo apps. Android and web versions are still under planning.
Key features
Automatic text generation: After uploading an image or video, users select a preset tone—like humorous, inspirational, poetic, or casual—and Capit instantly produces five stylistically consistent, semantically relevant social media captions. For example, “When land meets the ocean, stories settle with every gentle tide” comes from the poetic tone example.
Built-in caption editor: Users can easily add spaces, timestamps, and additional hashtags; a hashtag grouping feature will also be available in the future.
