NativeX

NativeX is a visual playground for Apple's on-device intelligence โ€” build prompt pipelines as a graph of cards, wire them together with variables, and run them right on your iPhone. Built for iOS engineers, prompt engineers, and the AI-curious: if you want to know what Apple's on-device model can actually do, this is the fastest way to find out. FREE AND PRIVATE Every run executes on the Apple foundation model that ships with your device. No account, no API key, no server: prompts, photos, and recordings never leave your iPhone, and inference costs nothing. LEARN THE REAL API Every card mirrors one Apple framework call and names the exact Swift symbol โ€” LanguageModelSession, NLTokenizer, RecognizeTextRequest, SpeechTranscriber, etc. Configure it in the inspector, run it, read the output. What you learn transfers line-for-line to Xcode. BUILD PROMPT PIPELINES โ€ข Prompt groups assemble instructions, few-shot examples, history, and the curreturn into a single transcript โ€ข Guided generation: constrain output to JSON with registered schemas, or design your own schema on the fly โ€” no rebuild โ€ข 17 native ops: tokenize, detect language, named entities, sentiment, OCR a photo, read a barcode, transcribe speech, speak text aloud, regex, JSON extraction, and more. Wait for more! โ€ข Human-in-the-loop pauses: type or dictate an answer mid-run EVALUATE LIKE A PRO โ€” LLM OPS, ON-DEVICE NativeX brings the modern LLM-ops workflow โ€” observability, datasets, evaluations โ€” to the model in your pocket: โ€ข Run History logs every execution as a step-level trace โ€” assembled prompt, output, timing, token estimates โ€ข Datasets batch-run a graph over a table of records, sequential or parallel โ€ข LLM-as-judge scoring runs on-device too โ€ข Re-run, reproduce, and compare past runs REQUIREMENTS NativeX runs the Apple Intelligence on-device model. That requires an iPhone 15 Pro or newer (A17 Pro chip or later) on iOS 26 or later, with Apple Intelligence enabled in Settings.
