## What is TangiLM?

TangiLM — Run AI Locally on Your iPhone

TangiLM is a mobile language model app that lets you run powerful chat and reasoning locally on your iPhone. No account required, no cloud subscription, and no need to send your prompts to remote servers.

Download your own GGUF models easily, manage them easily, and chat with full control over what runs on-device.

Key Features

Offline-first private chat
Run your language model locally for everyday conversations, brainstorming, Q&A, and writing. Keep your data on your device to support a more private workflow.

Download and manage local models
Browse, download, and load your favorite GGUF models from Hugging Face. The app scans your model directory, tracks download progress, and lets you switch models anytime.

Optional web search for up-to-date answers
When enabled, TangiLM can perform web searches and pull relevant page content to help answer time-sensitive questions. This hybrid approach keeps casual chat fast while still supporting more current information when you choose.

Built-in search workflow (analyzing → searching → evaluating → fetching)
For improved relevance, the app uses an advanced internal agent loop to refine search queries, decide whether to fetch a page, and combine results into the final context used for generation.

Thinking and searching controls
If your selected model supports advanced reasoning, you can enable a “thinking” mode for better step-by-step answers. You can also toggle the web search feature per conversation.

Fine-tuned performance and stability
TangiLM also lets you fine-tune inference parameters for better speed and stability. For newer model releases, the app provides strong compatibility and optimized inference behavior, which helps reduce the likelihood of overheating and crashes commonly seen in other iOS AI tools.

Session and history support
Your chat sessions are saved automatically so you can continue where you left off. Review messages, edit user content, and keep your workflow organized.

Multilingual UI and prompts
The interface is localized across multiple languages, and the app supports multilingual prompts for smoother international use.

Why TangiLM

local speed and privacy by default, with optional online search when you need it.

### 1/5 — 无法删除聊天会话

*2026-04-17*

1、聊天会话无法删除，点击删除后点击保存仍然无效
2、导入 qwen3.5 模型问答都说不出自己是谁，问几遍只会说自己是基于你选择的模型运行，合理怀疑本地导入功能都没做，塞了一个调试过的模型进来冒充

**Developer response:** 您好，谢谢您的评论！关于您的问题：
1: 如果要删除当前的对话，麻烦切换到其他对话后再尝试一下；
2: 模型的回答和输出能力基于模型选择和您的参数设置，我们在参数设置中提供了最大化的自由度，请麻烦着重查看一下system prompt，建议简化一些。我们没有也不会在本地塞入一个调试过的模型，如有疑惑，可以看一下APP安装包大小，谢谢！

### 5/5 — 很好

*2026-04-09*

**Developer response:** 感谢支持！如果有疑问，欢迎随时提出，谢谢！
