Your chats, voice transcriptions, and files stay on your device. Playground for LM is a private local AI workspace for Apple devices. Run supported language models with local llama.cpp-based inference, chat with models offline, manage your own model library, and transcribe supported audio locally with Whisper.cpp. The app includes a limited free trial so you can test the core workflow on your device. Playground For LM Pro unlocks the full experience, including extended local model usage, full transcription access, premium themes, and the exclusive gilded Pro app icon. Local AI Chat Run supported local language models directly on your device. Test models, compare responses, experiment with prompts, draft text, and build personal AI workflows without relying entirely on cloud-based chat services. Free users can try the chat workflow with a limited message allowance. Playground For LM Pro removes the free-user message restriction. Local Audio Transcription Turn supported recorded or imported audio into text with local Whisper.cpp-powered transcription. Review generated transcripts and organize spoken content into cleaner, more readable text. Free users can try transcription with a limited allowance. Playground For LM Pro unlocks the full transcription workflow. Model Library Management Choose or create your own model library folder. Add models, load them, chat with them, and unload them when you are done. Playground for LM is designed for users who want clear control over where their models are stored and how they are used. Clean Output Rendering Playground for LM supports readable rendering for common AI-generated formats, including Markdown, code blocks, LaTeX formulas, tables, and structured lists. System Diagnostics View useful runtime and model information while working with local AI. Depending on your device, model, and workflow, the app may display loading state, model status, memory-related notes, transcription state, runtime behavior, and generation performance. Playground For LM Pro Upgrade to Playground For LM Pro to unlock extended local model usage, full local transcription access, premium themes, the exclusive gilded Pro app icon, and future Pro features. Privacy-Oriented by Design When using supported local language models, inference runs on your device through the app’s local runtime. When using local transcription, supported audio is processed on device. Some actions, such as downloading models, importing files from external locations, restoring purchases, completing in-app purchases, or opening external legal documents, may require a network connection. Important Notes Playground for LM does not include every possible AI model or transcription model by default. Users are responsible for ensuring that any model they use is compatible with the app and that they have the right to use it. Local AI models and transcription models may require significant storage, memory, and processing power. Larger models may load slowly, fail to load, or perform differently depending on your device. Generated content and transcription results may be inaccurate, incomplete, or misleading. Speech transcription may be affected by background noise, speaker accent, audio quality, language, and model limitations. Always review important information carefully before relying on it. Playground for LM gives you a practical way to experiment with private local AI on Apple devices: local chat, Whisper.cpp-powered transcription, model management, clean rendering, diagnostics, and a focused workspace under your control.

Keep the details from a meeting, revisit a lecture or capture an idea before it disappears. RecordMind turns recordings and selected audio files into searchable text, with timed passages you can replay alongside the original audio. START FREE. UPGRADE ONCE IF YOU NEED MORE. Use the included model for basic transcription. Record up to 5 minutes at a time on iPhone, or import longer audio and transcribe the first 5 minutes free. Copy and share the available plain transcript text without Pro. With Pro, you can complete a preview transcript when its original audio and required model remain available. RecordMind Pro is an optional one-time in-app purchase, not a subscription. It removes the free 5-minute limit and unlocks advanced models, local summaries and Markdown, SRT and OPML exports. Recording length and processing still depend on device storage and system conditions. TRANSCRIBE ON YOUR DEVICE Speech recognition runs locally; your audio does not need to be sent to a transcription server. The basic model is included. Additional models require an internet download before offline use. Choose a language and model to suit the recording and your device; speed and quality vary with audio, language and hardware. FIND AND REPLAY THE DETAILS • Record audio or import a selected audio file • Organize notes into meetings, ideas and interviews • Search saved titles and transcript text • Tap a timed passage to replay retained audio • Adjust playback speed and move back or forward 15 seconds • Copy the available transcript text or an individual passage SUMMARIES AND EXPORTS WITH PRO Get a shorter view of a transcript through on-device key-sentence extraction. Summaries select passages from the source; they are not a conversational AI or a guarantee that every decision or action is captured. Check important details against the original. Export Markdown for your notes, SRT subtitles when timing information is available, or an OPML outline for a mind-map workflow. These formats require Pro; plain-text copying and sharing do not. FOLLOW RECORDING AND TRANSCRIPTION Optionally enable live captions to see text while recording. On supported devices and system versions, Live Activities show recording or transcription progress. Interrupted transcription jobs can offer a resume option when saved progress is available; do not rely on uninterrupted background processing. RECORD WITH APPLE WATCH Capture audio on Apple Watch and send it to your paired iPhone for transcription. The watch interface follows your app language. Transcription runs on iPhone, not independently on the watch; transfer timing depends on connectivity and system conditions. For meeting notes, study, interviews and voice memos. Start with short recordings, then unlock Pro once when you need more. No subscription. RecordMind is not a phone-call recorder. Record only with any required permission or consent.
