About

JSON Pilot

Features
Read full description

A native JSON viewer and editor for iPhone, with an on-device AI assistant that explains your data without sending a byte to the cloud. JSON Pilot opens any JSON โ€” from Files, the share sheet, AirDrop, your clipboard, or an HTTP request you fire from inside the app โ€” and gives you three ways to read it: a syntax-highlighted Tree, a tap-to-edit Fields drilldown, and a Text view with line numbers. Edit at any level, prettify or minify, validate with a precise line:col error, and Save the edits back to the original file. โ€” FREE FOREVER โ€” The whole viewer and editor is free with no account, no nags, no cloud sync. View, edit, validate, format, minify, search, Save, Save to Files, Share, Copy. We never gate the basics. โ€” ON-DEVICE AI ASSISTANT โ€” Ask "What is this JSON?" or "Find issues" or "Extract all emails" and JSON Pilot answers locally, using Apple Foundation Models. Your JSON, your prompts, and the model's replies never leave your iPhone. No server, no API key, no cloud fallback. (The AI assistant requires an Apple-Intelligence-capable iPhone โ€” 15 Pro and the full 16/17 family. On other devices the assistant is automatically disabled; everything else in the app still works.) โ€” POWER TOOLS (PRO) โ€” โ€ข JSON Diff โ€” compare two payloads by structure. Reformatting is never a change. Summary view groups Changed / Added / Removed; Unified view shows a GitHub-style line diff. โ€ข JSONPath queries โ€” $, ., [i], [*], .. and more. Matches highlight right on the Tree. โ€ข Format conversion โ€” export to YAML, CSV, or XML. โ€ข HTTP request tool โ€” send GET / POST / PUT / PATCH / DELETE with custom headers, open the JSON response in the same workspace. โ€ข Auto-fix โ€” repair broken JSON: trailing commas, single quotes, unquoted keys, comments, smart quotes. โ€ข Themes โ€” accent color and three syntax palettes. โ€” PRIVACY YOU CAN VERIFY โ€” Zero analytics SDKs. Zero telemetry. Zero crash reporters. The only network traffic the app initiates is StoreKit (your purchases) and HTTP requests you fire yourself. Recents are stored locally โ€” CloudKit is explicitly disabled. JSON Pilot does not request Camera, Photos, Contacts, Microphone, Location, or any other iOS permission. โ€” UPGRADE TO PRO โ€” Two ways to unlock the same Pro features: โ€ข Monthly subscription โ€” billed monthly, cancel anytime. โ€ข Lifetime โ€” one-time purchase, keep Pro forever. Both options unlock the same features. See the App Store listing for current pricing in your region. Manage or cancel anytime in iOS Settings โ†’ Apple ID โ†’ Subscriptions. โ€” REQUIREMENTS โ€” iPhone running iOS 26.4 or later. AI features require an Apple-Intelligence-capable iPhone. โ€” SUPPORT โ€” Questions, bugs, ideas?

Difftray brings code review to your phone and tablet. Pair it with the open-source Difftray desktop app, then read git diffs, browse every changed file, and leave line-by-line comments โ€” all over your own local network, with no cloud in between. Difftray is a companion app. It works alongside the Difftray desktop app running on your Mac. Scan a QR code once to pair, then pick up any project from the couch, a meeting room, or the other side of the office. REVIEW DIFFS ANYWHERE Read inline diffs with real syntax highlighting, sized for small screens. See additions and deletions at a glance, move between changes, and mark each file reviewed as you go. BROWSE CHANGED FILES Step through every changed file in a project and see exactly what moved, with per-file and total added/removed line counts. HAND OFF TO YOUR CODING AGENT Leave comments on the lines that need work, then export them as an agent-ready prompt. Copy it or share it straight into your AI coding agent so the fixes are queued up before you're back at your keyboard. ALL YOUR PROJECTS Every project open on your desktop is one tap away on your phone or tablet. PAIR LOCALLY, STAY PRIVATE Connect by scanning a QR code or entering a short code โ€” no account, no sign-up. Your phone talks directly to your own computer over local Wi-Fi, or over your private Tailscale network when you're away from your desk. Pairing is end-to-end encrypted, and your code never touches a server we run. REQUIREMENTS Difftray requires the free, open-source Difftray desktop app with its companion server enabled. This mobile app is a companion to that desktop app and does not work on its own. Pair your phone, step away from your desk, and keep reviewing.
