Side-by-side comparison · Updated September 2026

 Klu.aiKlu.aiPrivate LLMPrivate LLM
DescriptionKlu is an all-in-one LLM App Platform that allows users to experiment, version, and fine-tune GPT-4 Apps. It supports collaborative prompt engineering, enabling teams to explore, save, and prototype completions, assistants, and workflows. The platform also offers functionalities for tracking and integrating changes into product development workflows, and it automatically evaluates prompt and model changes. The Klu platform is compatible with best-in-class LLMs such as Llama 2 and Mistral 7b, and it enables users to fine-tune custom models with curated data.Private LLM runs text-based AI models locally on supported iPhones, iPads and Macs. It is a useful alternative for personal writing, summaries and questions when you want an on-device assistant instead of a hosted team workspace. Download a suitable model first; supported models and performance depend on your device and available memory. The US App Store lists a one-time price of $4.99. The developer describes access across supported Apple platforms with Family Sharing for up to six people and no subscription. Check your own store region for the current price and device requirements. Siri and Apple Shortcuts integration can connect the assistant to your existing workflows. The app privacy policy says conversations stay on-device and are not collected by the developer. This is distinct from the product website, which has analytics and a support form, and from the network requests needed to download models. Local processing is useful for controlling your chat data, but it does not establish that every model answer is correct or that every model will run well on every device.
