Signa AI vs Cube Solver AI

Signa AI turns everyday text, audio and speech into sign language, right on your iPhone or iPad. Type or paste a sentence, record your voice, or upload an audio file and watch a clear avatar sign it back to you. Built to make communication more accessible for the Deaf and hard-of-hearing community, Signa AI works in Kinyarwanda, French and English. What you can do • Type or paste text and see it signed • Record your voice and have it transcribed, then signed • Upload an audio file (MP3, WAV, M4A) and get a signed version • Watch a clean, easy-to-follow signing avatar • Revisit your previous translations anytime in the History tab at no cost Languages Speak or type in Kinyarwanda, French or English, then choose your sign-language output: Kinyarwanda Sign Language, American Sign Language, French Sign Language or British Sign Language. Signed output is powered by a research-backed pose model, and our coverage keeps improving. Who it's for • Schools and teachers caption lessons for Deaf students • Creators and YouTubers add a signing avatar to your videos • Broadcasters and organizations make announcements accessible • Anyone who wants to connect with Deaf friends, family or customers Signa AI is built by Xendly Labs in Kigali, Rwanda.

Completely free. No in-app purchases, no subscription, no paid tier, no account — every feature described below is simply there when you open the app. Point your camera at each face and Cube Solver AI reads the colours for you, then walks you through the solution one turn at a time, with the layer actually rotating on screen. SCAN WITH YOUR CAMERA A neural network trained for colour constancy runs entirely on your device, so it copes with warm lamps, cold daylight, and the glare that makes white and yellow look alike. A live overlay shows exactly which colour it reads on every sticker while you hold the cube, so you can see it working before you commit. FIX ANYTHING IT GETS WRONG Detection is never perfect on every cube in every light. Tap any sticker on the 3D cube or the flat net to repaint it, with undo and redo throughout. Stickers the model was unsure about are highlighted, so you know where to look first. SOLUTIONS YOU CAN ACTUALLY FOLLOW Every step names the move, describes it in plain words, and animates the layer swinging on the cube, which is far more useful than a line of notation. Step back and forth freely, jump to any move, or hand it to auto-solve and just watch the cube unscramble itself. Choose slow, normal or fast, and let the camera follow the turning face or stay put. 3x3, 4x4 AND 5x5 The 3x3 uses a two-phase search that finds solutions of around 20 moves. Larger cubes are solved by reduction: centres first, then edge pairing, then the 3x3 finish, including the parity cases that only appear on even cubes. FREE, PRIVATE, OFFLINE The neural network and the solver both run on your iPhone, so your photos never leave the device and nothing is collected about you. It works with no signal at all.
