Use Apple Private Cloud Compute, your 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 - Apple Private Cloud Compute - 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. - Rich, editable conversations. Markdown, LaTeX, code blocks, attachments, edit and export anything. - Private by design. iCloud sync across devices. Nothing saved to our servers. - Native and accessible on iPhone, iPad, and Mac.

Verdict

The call

The clearest difference is rating: Cumbersome at 4.9 against opchat's 4.0. Cumbersome also leads on ratings volume (102 vs 2) and update cadence (every 4 days vs every 2 weeks). opchat's advantage is review sentiment (100% vs 89%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Cumbersome holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Cumbersome has 102 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 89% of Cumbersome's written reviews are positive against 100% of opchat's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Cumbersome ships an update every 4 days, opchat every 2 weeks. Both last shipped on November 9, 2026.
