## Cumbersome Description
IMPORTANT: Requires your own provider API keys or an OpenAI-compatible endpoint.

I built Cumbersome because consumer AI apps kept dumbing things down. Cumbersome is the manual transmission of AI apps: more complex, but with far greater control.

WHY I BUILT THIS

Consumer AI apps hide the controls I want and lock me into one provider.

I wanted direct API access, the freedom to pick and compare models, and to pay providers for what I use. This is the app I use every day, so I pay attention and try to get it right.

SUPPORTED PROVIDERS

- ChatGPT / OpenAI
- Claude / Anthropic
- Gemini / Google AI Studio
- OpenRouter multi-provider
- Vercel AI Gateway multi-provider
- Z.ai
- OpenAI-compatible custom endpoints, including Ollama, Azure, LM Studio, Groq, Together, and self-hosted backends

WHAT YOU GET

- A versatile API client. One app, every major provider and model.
- Total control. Pick your model, tune the parameters, switch providers mid-conversation.
- Compare models head to head. Stream multiple chats in parallel and let an AI judge pick the best.
- Bring your own tools. Local browser use, reasoning, web search, image generation.

## Cumbersome Reviews in United States

### ***** "Perfect for local AI"
I tried several apps before I found this to connect to a model I host on my own hardware. I almost thought I would have to build it myself. This is exactly what I wanted to build!
-- Matt Always Building, 2026-09-14

### *---- "Plagued with analytics: app-analytics-services.com gets hammered."
Constant Firebase analytics outbound connections. 

Small developers have become the new surveillance dark horses, more dangerous than big tech, because we trusted them.

Shame on you.
-- Rtr8, 2026-09-10

### ***** "The Perfect Blend"
This LLM client’s approach is the perfect blend of simplicity and complexity. For example, it’s simple and has a straightforward conversation history but an individual chat can easily be exported in full JSON for another agent to use if you need to take a conversation to the next level. Or how it uses iCloud for seamless sync. Peter rocks!
-- OrganizeIt, 2026-08-01

### ****- "No macOS 15 local search support?"
Everything is great except for no macOS 15 local search support. Is this a technical limitation?
-- Douglas F. Williams, 2026-07-15

### ****- "优势是免费、手机电脑同步"
轻量化、清晰顺滑、免费、接入友好。有几个小缺憾：1. 长文本输入输出的时候有概率出现滑动卡顿、闪屏、显示故障。2. 侧栏 ui 的颜色有些刺眼，对于一个大量阅读的 app 来说最好还是配色风格温和专业一些。3. 添加 provider 之后无法修改，调试换端点稍有点麻烦，但问题不大。
-- Tesethus, 2026-07-02

### ***** "Just the right amount of complexity"
Reading the history of this developer (hi, Peter!), I shouldn’t be surprised at how well this app is put together. It integrates complexity very well. It thoughtfully fills gaps between what models offer and clients typically provide. Plus it’s just really (really) fast to start and sync.
-- john.catalano, 2026-06-27

### ***** "Exactly what I needed"
I’ve been using this app since it came out. I’ve long wished for certain features and hoped for continued updates. It’s worked fine, however, the past 5 versions or so have finally given me the features I’ve been waiting for the whole time and it’s amazing. Separate system prompts, chat scoped system prompts,, toggleable parameters, more fixes to the streaming text Views, all the newer OpenRouter backend tool support. He even added COMPACTION! That’s amazing! Thank you so much! Love this app.
-- Ailthrim, 2026-06-23

### ***** "Excellent LLM client"
I’ve been using local LLMs through openwebui for a while, but the lack of a proper iPad client makes the usability hard. Cumbersome is an excellent alternative to being able to access models you host on your own network. If you use VPN or tailscale, you’ll always have access to these models.
-- codeanish, 2026-06-06

### ***** "REGENARATION"
pls pls pls add a regeneration feature
-- Tvoe_Serde4ko, 2026-05-29

### ***** "Very awesome, but.."
The app itself is pretty cool! And very nice and easy to use for Local LLMs, but I do have an issue.. some APIs actually provide free-to-use, with no api key required… and the app needs an API key, so im asking if we can get update to make it not needed or whatever. 

Overall, Thanks!
