Changelog

Improvements

• Simpler AI Model Selection - No more confusion with 10+ models. We now show 5 recommended models at the top with plain-English descriptions like "Balanced quality and price" or "Best UI/UX design quality".
• New Default: Claude Sonnet 4.5 - The best balance of quality and cost. Creates beautiful designs without burning through credits too fast.
• Power Users: Other Models - Need something specific? Click "Other models" to access Grok, Gemini, and GPT variants. Collapsed by default to reduce clutter.

Improvements

• Import from AI - Redesigned - The "Import from AI" popover now clearly explains what it's for: importing code from ChatGPT, Gemini, Grok, or any AI assistant. Each step has a help tooltip explaining exactly what to do.
• 90%+ Success Rate - Smart content detection now works almost perfectly. Paste any code and Playcode figures out if it's HTML, CSS, JavaScript, Python, C, C++, Go, or SQL and puts it in the right file automatically.

Improvements

• AI Now Understands All Languages - The built-in AI assistant now fully understands Python, C, C++, Go, and SQL projects. It knows how each language works in Playcode, including entry points, package management, and execution modes.
• Import from AI - Multi-Language - The Import from AI feature now detects Python, C, C++, Go, and SQL code automatically. Paste code from ChatGPT or Claude and it goes to the right file (main.py, main.c, main.cpp, main.go, or main.sql).
• Smarter Code Detection - Improved detection patterns for all supported languages. Python imports, C/C++ includes, Go packages, and SQL queries are now recognized instantly.

New

• Import from AI - New button in the header to easily import code from ChatGPT, Claude, Gemini, or any AI assistant. Just copy the AI's response and paste it directly. Playcode automatically detects whether it's HTML, JavaScript, or CSS and puts it in the right file. No more manually creating files or figuring out where code should go.

Improvements

• Smart Content Detection - When you paste code, Playcode now intelligently detects the content type. HTML goes to index.html, JavaScript to your main script file, and CSS to your stylesheet. Works perfectly with code copied from ChatGPT Canvas.
• One-Click Undo - Made a mistake? The Import panel includes Undo/Redo buttons so you can quickly revert any changes without leaving the workflow.

Fixes

• Assets Lost When Deleting Cloned Projects - Fixed a critical bug where images and other files would disappear from your original project after deleting a cloned copy. The issue occurred because cloned projects were sharing file references with the original instead of creating independent copies. Now when you clone a project or create a new version, all assets are properly duplicated to separate storage locations, ensuring each project's files are completely independent.
• Version Creation Reliability - Fixed an issue where creating a new project version could fail with a timeout error. The version creation process has been redesigned to work reliably without interrupting your current editing session.

Fixes

• Missing Projects After Update - Fixed a critical bug where some users couldn't see their projects after app updates. The issue occurred when internal data structures changed, causing the app to read from empty storage instead of existing data. Projects are now automatically recovered from the server when this situation is detected. No more need to log out and back in.

Improvements

• Go Runtime Now Works Everywhere - Rebuilt the Go interpreter with self-hosted WebAssembly. No more CDN dependencies that were blocked in some regions. Go code execution is now reliable worldwide.
• Python Runtime Self-Hosted - Core Python runtime (Pyodide 0.29.1) now loads from our servers instead of external CDN. Faster initial load and works in regions where jsdelivr was blocked.

New

• Multi-Language Playground - Playcode now supports Python, SQL, C++, C, and Go alongside JavaScript/TypeScript. All languages run 100% in your browser via WebAssembly. No server, complete privacy.
• Python with Pyodide - Full Python 3.12 with pip package manager. Install NumPy, Pandas, Matplotlib, scikit-learn, and 300+ packages. Visualizations render inline.
• SQL with PostgreSQL - Real PostgreSQL via PGlite with persistent IndexedDB storage. 18+ extensions including pgvector for AI, pg_trgm for fuzzy search. Database Explorer with pagination.
• C++ and C Compilers - Modern C++20 and C17 support via Clang/LLVM compiled to WebAssembly. Write, compile, and run instantly.
• Go Compiler - Run Go code in browser using Yaegi interpreter. Standard library support included.

Improvements

• Language-Aware UI - Header buttons adapt based on project language. Preview for JavaScript, Output for Python/C++/Go, Database Explorer for SQL.
• Python Package Manager - See popular packages (NumPy, Pandas, Matplotlib) immediately. Install any PyPI package by typing its name.
• New Templates - Quick-start templates for Python, SQL (PostgreSQL and SQLite), C++, C, and Go. Create a new project and start coding in seconds.

New

• AI Access Control - Project owners can now disable AI chat for collaborators. Perfect for coding interviews where you want to test candidates without AI assistance. Find the toggle in Share settings (Pro feature).

Improvements

• Redesigned Navigation - Console, Preview, and AI buttons now have text labels for better discoverability. Core features should be visible, not hidden behind icons.

Improvements

• Redesigned AI Mode Selector - The mode selector now explains exactly how to work with AI. Each mode is color-coded: Plan (blue) for planning, Agent (green) for building, and Ask (orange) for questions only.
• Recommended Workflow Guide - The menu now shows "Plan → Agent → Ask" as the recommended workflow, with step numbers (1, 2, 3) and clear descriptions for each mode. Perfect for non-programmers!
• Mode Badges - Each mode has a helpful badge: "Start here" for Plan, "Default" for Agent, and "Read-only" for Ask.
• Learn More Link - Quick access to detailed documentation about how each mode works.
