Pocket Typewriter vs LLM Studio Go

Platn is a pocket typewriter for your phone. One sheet. A 15-minute ruler. Done. No account. No sync anxiety. No subscription. Write now. Edit later somewhere else. Support is an optional tip. Nothing unlocks.

LLM Studio Go brings local AI to iPhone and iPad. Choose a model, download it, and run it on your device without creating an account. NEW: VIDEO (BETA) • Video studio: describe an idea and get a short vertical video. A chat model writes the script, a speech model narrates it, music plays underneath, and image and video models create the scenes and the cover. • Video from text: FastWan models turn a description into a short clip. Each model shows the memory it needs; video needs a device with at least 6 GB of memory. • Video generation is in beta: it is slow, uses a lot of battery and heats the device. AUDIO AND VOICE • Voice conversation: speak to a chat model and hear its answer, with live captions. Speech recognition, replies and speech run on your device. • Music and sound effects: describe a mood, instruments or a scene and get a track of up to 2 minutes. • Songs with vocals: write your own lyrics or let a local model write them, then pick a style and a singer. • Natural speech: turn text into speech in more than 30 languages with several voices. • A built-in player with waveform, speed, repeat and lock-screen controls. Save tracks as WAV or share them. LOCAL AI • Chat with supported language and vision models. Attach PDF, Word, Excel, PowerPoint, text files or images to a conversation. • Generate images with compatible diffusion models. • Browse GGUF and MLX models, import your own files, and manage downloads. • Keep conversations on your device and use models offline after downloading them. • Optionally enable DuckDuckGo web search and reading of linked pages for answers with sources. • Measure model performance and, if you choose, enable an OpenAI-compatible API for devices on your trusted local network. Model availability and speed depend on your device, its free storage, and the model you choose. Audio models are large downloads; songs need an iPhone or iPad with at least 12 GB of memory and are created while the app is open. Internet access is needed to browse and download models. Web search and link reading are off by default; when enabled, search queries go to DuckDuckGo and page requests go to the websites visited. The model catalog, the model picker and the audio generation screen may show ads. An optional one-time “Remove Ads Forever” purchase removes those ads and can be restored with the same Apple Account. All local AI features are available without the purchase.
