Sifr is a mobile-first, AI-powered IDE that lets you work on your real codebases from your phone. In a world where AI writes 95% of code, you don't need a keyboard — you need to direct, review, and ship. Sifr lets you do that from anywhere. KEY FEATURES • AI-Powered Development Tell the AI what to build in natural language. It reads your codebase, plans the implementation, writes the code, and waits for your approval. • Work on Real Projects Connect your GitHub repositories and work on actual codebases. Not toy apps — your production code. • Full Git Workflow View status, review diffs, stage changes, commit, and push — all from your phone. Ship code without opening your laptop. • Permission Control Choose how much freedom the AI has. Safe mode for exploration, Balanced for everyday work, or Autonomous for power users. • Multi-Model Support Access Claude, GPT, Gemini, and more through OpenRouter. Pick the best model for each task, or let Sifr auto-select. • Transparent Pricing Pay for what you use. See costs in real-time. No surprise bills. PERFECT FOR • Quick bug fixes while commuting • Code review on the go • Shipping features from anywhere • On-call incident response • Learning and experimentation FROM ZERO, EVERYTHING IS BUILT Sifr (صفر) is the Arabic word for "zero" — the origin of the word "cipher" and the concept of zero in mathematics. From nothing, we create working software. Start building today. Terms of Use: https://sifr-prod.up.railway.app/legal/terms

About

Sidecar ML

Features
Read full description

Turn your iPhone into a private, on-device AI server for your whole network. Sidecar ML runs a lightweight HTTP server on your iPhone that exposes Apple's built-in machine-learning models to any device on your local network. Tap Start Server, scan the QR code, and your Mac, PC, Raspberry Pi, or browser can call powerful on-device AI over plain REST — no cloud, no accounts, no API keys, no usage fees, and no data leaving your network. Everything runs on the phone. Nothing is uploaded to a server and there's nothing to pay for. (The one exception, music recognition, matches against Apple's catalog and tells you so up front.) ONE IPHONE, A DOZEN AI CAPABILITIES • Chat with the on-device large language model through a chat-completions endpoint that's compatible with the popular OpenAI API format — streaming, JSON mode, and structured output included. Point existing tools and SDKs at your phone and they just work. • Generate images from a text prompt in a choice of art styles. • OCR — pull text out of photos, receipts, and screenshots with per-line boxes and multi-language support. • Read barcodes and QR codes (EAN, Code128, and more). • Classify images across roughly a thousand categories, or produce image embeddings for similarity search. • Remove backgrounds and isolate subjects or people as clean PNG cut-outs. • Detect faces and facial landmarks, body pose, and hand pose. • Scan documents with automatic edge detection and perspective correction. • Convert speech to text and text to speech, with a wide range of voices (including Personal Voice). • Translate text between languages completely offline. • Analyse text: language, sentiment, named entities, tokens, and embeddings. • Classify sounds across hundreds of categories, or identify the music that's playing. BUILT FOR DEVELOPERS AND MAKERS • Clean REST + Server-Sent Events API — call it from curl, Python, JavaScript, or any HTTP client. • Chat endpoint compatible with the OpenAI format, so many existing tools and SDKs work unchanged. • Automatic discovery on your network via Bonjour. • Honest capability reporting: ask the server what it can do and it tells you exactly what's available on your device, and why. • Optional bearer-token authentication to lock the server down on shared networks. FREE WEB CONSOLE AND CODE EXAMPLES A ready-to-use web console — plus Python examples, a command-line client, and full API documentation — is free and open-source. Download the single-file console and browse the source here: https://github.com/AndersFB/Sidecar-ML-Console/ Open the console in any browser, enter your phone's address, and try every capability with a friendly UI — nothing to install. GOOD TO KNOW • The on-device large language model and image generation require an Apple Intelligence-capable iPhone. The other capabilities run on a much wider range of devices. • The server runs while the app is in the foreground; a keep-awake option helps during longer sessions. • Some features (offline translation language pairs and certain speech models) download their models on first use. Turn the iPhone in your pocket into a private AI endpoint for your projects, your home lab, and your prototypes — Sidecar ML.
