The AI-proof IDE.
Native Mac. All-in-one.

Mobile developers run four IDEs.
None were built for AI.

• Xcode for iOS, Android Studio for Android, VS Code for web, Cursor for AI. Daily context-switching tax: 30–60 min, every developer, every day.
• AI agents now write production code — Claude, Codex, Gemini, DeepSeek. But every existing IDE was designed before agents existed.Result: silent corruption of project.pbxproj, Info.plist, Gradle files, entitlements. The agent says "done." The build is broken. You don't know why.
• Cursor doesn't ship to iOS or Android. It can't open an .xcodeproj, drive the iOS Simulator, or sign for the App Store. Mobile teams can't actually use it as a daily driver.
• Electron-based AI editors burn 2–4× the RAM and battery of a native Mac app, on a platform where developer hardware is the work surface.

One native IDE.
Built so AI edits can't wreck the project.

LingCode is a from-scratch Swift-native Mac IDE with a unique work-protection layer wrapped around every AI tool call.

• Pre-edit snapshots of every project-critical file before any agent touches it. Project files, build configs, signing entitlements, Gradle — auto-protected.
• Per-hunk review & semantic time-travel undo — keep the good edits, reject the bad ones, three commits later. No other AI editor offers this. Cursor's checkpoint is file-level. Ours is hunk-level + semantic.
• All four IDEs, replaced. iOS Simulator, Android Emulator, LLDB, xcodebuild, Gradle, code-signing, Postgres tools, and Claude Code / Codex / Gemini CLI — built in.
• Native. No Electron. Boots in <1s. Lower RAM, longer battery, on the platform that matters most to developers.

The agent era forces a new IDE category.

• 2025 was the year coding agents went mainstream. Cursor > $500M ARR, Claude Code at GA, every YC company is shipping with an agent in the loop.
• Trust, not capability, is now the bottleneck. The next billion lines of code will be written by agents — and the next $1B IDE will be the one developers trust to let an agent run unsupervised.
• Apple silicon made native viable again. Electron's "good enough" excuse weakens when M-series Macs make a Swift-native app feel like a different category of software.
• Mobile is still a gap. Cursor and Windsurf treat iOS/Android as out-of-scope. We started there.

Replaces four IDEs. Adds the safety layer they all lack.

• Built-in agents: Claude Code, Codex, Gemini CLI, DeepSeek — pick a provider per task or per file.
• Built-in deploy: one-click App Store and Google Play, including signing and version bumps.
• LingModel proxy: our own routing layer — users get a free agent tier without holding any API keys.
• RTK token compression — bundled, zero-config: LingCode is the first IDE to ship RTK (Rust Token Killer) pre-bundled. Every bash tool call is compressed 60–90% before it reaches the model. Quota stretches further; context stays leaner. No install, no init.
• Cross-device: Mac app + iPhone/iPad app + CLI + browser playground at /try.

Mac-first developers shipping mobile + web.

Beachhead: the ~6M mobile devs Cursor can't actually serve. Expand: every Mac developer touching multiple platforms.

Shipped, signed, paying users.

Free → Pro → LingModel margin → Enterprise.

• Free. Native IDE, work-protection, all four IDE replacements. Drives top-of-funnel and word-of-mouth among Mac devs.
• Pro · $20/mo. Higher LingModel quotas, advanced undo history, team sync, priority support.
• LingModel proxy margin. We resell upstream model calls at a structural margin. Users get an agent without paperwork; we earn on every token.
• Enterprise · later. Air-gapped + BYOK + SSO + audit log. Mobile-shop teams who can't use Cursor for compliance reasons.

No one else does all-in-one + native + work-protection.

Moat: native Mac engineering depth (multi-year), the work-protection layer, and a cross-surface footprint Cursor can't ship without rebuilding from scratch.

200 apps in. The IDE was the bottleneck.

• Weijia Huang · Solo founder & CEO. Shipped 200+ apps before LingCode — iOS, Android, web, native Mac. LingCode was built out of the friction of building all of them.
• The insight. After that many builds, the limit on what I could ship was never the language, the framework, or the model. It was the tools — the daily tax of switching between Xcode, Android Studio, VS Code, and Cursor.
• AI made it worse, not better. Agents removed the language barrier, so multi-platform native development became standard. But every IDE was still single-platform. The tool tax went up, not down. That's the gap LingCode closes.
• Why solo, why fundable. v2.0 is already shipped — Mac app, iOS / iPad app, CLI, browser playground — code-signed, notarized, paying users, no funding to date. Capital accelerates a proven build, not a hopeful one.

Build the IDE the agent era actually needs.

If you invest in dev tools, native software, or the AI infrastructure layer — we'd love a conversation.
