About

Sigmix One

Features
Read full description

Sigmix One puts eleven business tools on your device and runs every one of them there. Ask a question and get an answer. Write a social post and create the picture that goes with it. Turn a rough idea into a priced proposal, a brochure or a slide deck. Draft a professional email. Create an image, or generate a sheet of logo concepts to choose from. Make a vertical reel. Read a contract and get the short version. WHAT MAKES IT DIFFERENT Sigmix One uses the power of your iPhone or iPad GPU, together with Apple Metal technology, to run AI models directly on your device. The models are downloaded once and then run locally using your device's own hardware. Your words, files and pictures stay on your device. Nothing is uploaded, nobody else sees them, and no account is required. Turn off your internet connection completely and everything still works. On a plane, in a basement, or on a SIM with no data left. That is not a privacy setting you switch on. It is simply how Sigmix One works. NO SUBSCRIPTION Everything is included. No credits, no charge per document and nothing to cancel. The models use open weights under the Apache 2.0 licence, so there are no recurring model usage fees for us to pass on to you. ARABIC FIRST Built for Arabic and English, in that order. Documents, presentations and posts lay out properly from right to left, rather than using a mirrored English template. Every tool responds in the language you use in your brief, regardless of which language the app interface is set to. WHAT YOU GET Ā· Chat: ask anything, read a file, get the short version Ā· Posts: caption, hashtags and image, ready to publish Ā· Reels: vertical video, around nine seconds Ā· Emails: designed emails, not walls of text Ā· Proposals, Brochures and PowerPoint: real documents, built page by page Ā· CV: turn your experience into a well structured CV Ā· Images: create images with no watermark Ā· Logos: generate two to ten concepts from one idea Ā· Enhance: improve a photo instantly, with no additional model download required THE DOWNLOAD The app itself is small. The AI models are downloaded separately over Wi-Fi. The writing model is about 3 GB. The image model requires around 4 GB more if you want to use the image generation tools. Once downloaded, the models do not need to be downloaded again, and Sigmix One shows you the size before each download begins. Sigmix One requires iOS 26 or iPadOS 26 because its on-device AI models rely on technologies available in those versions. Made in the Kingdom of Saudi Arabia.
