1. Description of the Services

Chat LLM provides multiple ways to interact with AI:

On-Device Local Model (Optional): Chat LLM offers an optional local AI model that runs entirely on your device. The model is not bundled with the app; it is downloaded on demand from Hugging Face the first time you tap the Local LLM card in the model picker. After this initial download, no internet connection is required and no chat content is sent to external servers when using the local model. You can delete the downloaded model at any time from the model picker to reclaim storage.

Free Cloud AI (Groq): Chat LLM provides a free cloud AI option that does not require an API key. This service requires an internet connection and may be subject to shared usage limits across users. Free cloud AI is text-only and does not support image or document uploads. Messages and conversation content are forwarded to Groq to generate AI responses.

Voice Chat (Optional) (Google Gemini or xAI Grok): Chat LLM supports real-time voice conversations through two backends. With Google Gemini (requires your own Gemini API key), voice chat includes built-in Google Search grounding, so Gemini may automatically perform web searches to answer questions about current events or live information, and you may attach photos or camera images during a session; these are transmitted to Google for processing. With xAI Grok (requires your own xAI API key, or sign in with your xAI account to use your existing xAI subscription), spoken input and conversation content are processed by xAI. You are responsible for any API usage or subscription costs charged by the provider you use.

Grok Text Chat (Optional) (xAI): When you are signed in with your xAI account (or have provided an xAI API key), Grok text models are available in the model picker. Messages and conversation content are sent to xAI to generate responses, using your xAI subscription or API account. You are responsible for any costs charged by xAI.

AI Image and Video Generation (Optional) (OpenRouter or xAI): Chat LLM can generate images and videos into the chat thread using media models from OpenRouter (requires your own OpenRouter API key) or xAI (requires your own xAI API key or an xAI sign-in). Your prompt and any reference images you provide are sent to the selected provider, and the result is stored on your device. Generation and editing costs are billed by the provider to your own account; per-model prices are shown in the app where the provider publishes them. Cancelling an in-progress generation in the app may not stop the provider from completing the job and billing it. You are responsible for ensuring you have the rights to any reference images you supply and for how you use generated media.

Web Search (Optional) (OpenRouter): When using OpenRouter models in Chat LLM, you may enable real-time web search. When enabled, OpenRouter performs a live web search and incorporates the results into the model's response. A small per-search fee (~$0.004) is charged by OpenRouter to your account on top of normal model costs. You are responsible for any costs incurred.

Spoken Playback of AI Replies (Chat LLM): In Chat LLM, spoken playback of AI replies is handled by Reader. To hear a reply aloud, share the message into Reader (see Reader Mode below), where it is read using your selected text-to-speech provider and your own API key. You are responsible for any generation costs charged by that provider.

Reader Mode (Optional): Chat LLM includes a document reader that speaks any imported PDF, EPUB, TXT file, pasted text, or shared webpage/document aloud, sentence by sentence. You choose a text-to-speech provider per document — OpenRouter (Kokoro), MiniMax, ElevenLabs, Fish Audio, or xAI — using your own API key for the chosen provider (or your xAI sign-in for xAI). Text is sent to the selected provider to generate audio, which is returned and cached locally on your device. You are responsible for any generation costs charged by that provider. When importing a webpage, you may optionally add your own Groq API key to clean up the page text for clearer narration.

LM Studio (Optional): Chat LLM can connect to LM Studio running on your own computer and use models hosted there, over your own private network (for example, a Tailscale connection). Your chat content is sent directly to your own machine and not to us or any third-party cloud provider. If you configure MCP tool server names, the model may invoke those tools on your own machine, and any external requests they make originate from your computer. You are responsible for running and securing your own LM Studio server and any tool servers it calls.

iCloud Sync (Optional) (Apple iCloud): Chat LLM backs up your settings, system prompts, conversations, and imported Reader documents to your own iCloud account so they restore across your devices and after reinstalling. The data is stored in your own private iCloud, not on our servers. This uses Apple's iCloud and is governed by Apple's terms.

Bring Your Own API Key (Optional): Chat LLM allows you to connect your own API keys to use third-party services — including OpenRouter (text chat, web search, and image and video generation), Google Gemini and xAI (voice chat; xAI also covers Grok text chat and media generation via key or account sign-in), and OpenRouter (Kokoro), MiniMax, ElevenLabs, Fish Audio, and xAI (Reader text-to-speech), plus an optional Groq key for webpage cleanup. When using this option, the App sends your content (text, and where supported images and documents) to the selected provider and displays the responses returned. If you use OpenRouter, OpenRouter may route requests to different model providers depending on the model selected. We do not operate or control third-party services or models.

LLM Pro provides the following AI interaction options:

Free Cloud AI (Groq): LLM Pro includes a free cloud AI option that does not require an API key. This service requires an internet connection and may be subject to shared usage limits across users. Free cloud AI is text-only and does not support image or document uploads. Messages and conversation content are forwarded to Groq to generate AI responses.

Premium Subscription: LLM Pro offers a premium subscription service (£9.99 per month) that unlocks:

• Access to curated high-performance cloud AI models (processed by Groq and Cerebras, depending on the model selected)
• Real-time web search on supported models (powered by Serper)
• Vision capabilities on supported models (for image analysis)
• AI image generation and image-to-image editing with a monthly allowance (processed by Replicate)
• Spoken playback of AI replies (processed by Replicate)

AI Image Generation (Included with Subscription) (Replicate): LLM Pro includes image generation and editing processed by Replicate. Image generation requires an internet connection. A monthly image allowance applies and is displayed in-app (currently up to 100 images per month).

Spoken Playback of AI Replies (Included with Subscription) (Replicate): LLM Pro can play any AI reply aloud using the Kokoro voice model on Replicate. Generation requests pass through our backend server, which forwards them to Replicate. Generation costs are absorbed by the subscription — no API key is required and no per-message charge is passed on to you. Generated audio is cached locally on your device so repeat playback of the same message does not re-incur a generation cost.

Thinking Box (Optional): LLM Pro may display intermediate reasoning for supported models. Availability depends on the selected model/provider and may vary.

Voice Chat (Optional) (xAI): LLM Pro may support real-time voice conversations using xAI. This feature requires you to provide your own compatible API key. You are responsible for any API usage costs charged by xAI.

Bring Your Own API Key (Optional): LLM Pro may allow you to connect your own API keys to use third-party services such as OpenRouter, OpenAI, or xAI. When using this option, the App sends your content (text, and where supported images/documents/voice) to the selected provider and displays the responses returned. If you use OpenRouter, OpenRouter may route requests to different model providers depending on the model selected. We do not operate or control third-party services or models.

3. User Responsibilities

You agree that you will not use the Apps to:

• Upload or generate content that is illegal, harmful, or abusive;

You are solely responsible for ensuring you have the necessary rights to any content you import into, process with, or export from the Apps — including documents, webpages, and text you add to Reader, and any audio files you export from it. Reader's text-to-speech and audio-export features are intended for content you own or are otherwise permitted to use (for example, your own material, public-domain works, or content you hold a licence or other right to use). You must not reproduce, distribute, or share exported audio — or any other content produced with the Apps — in a way that infringes the copyright, privacy, or other rights of any third party. You are responsible for how you use and share anything you export.

When using features that require your own API key, you are solely responsible for:

• Obtaining and maintaining a valid API key from the third-party provider;
• All costs and charges incurred through your API usage;
• Complying with the provider's terms of service and usage policies;
• Monitoring and managing your API usage to avoid unexpected charges.

4. Third-Party Services
