Nul is a focus browser that gets out of the way of your intentions. Most of the internet is designed to pull your attention in every direction. Nul gives you a browser that only goes where you tell it to. BLOCK DISTRACTING SITES Add any website to your block list. Once blocked, visiting that site shows a simple reminder instead of the page. No redirects, no search results — just a quiet prompt to refocus. A COMMITMENT DEVICE, NOT A FILTER Removing a site from your block list takes 24 hours. That gap is the point. It's long enough to outlast the impulse, but short enough to feel reasonable. Your block list is backed by iCloud, so deleting and reinstalling the app won't bypass it. INTENTIONAL NAVIGATION Nul has no address bar. You open URLs from other apps, or scan QR codes with the built-in scanner. Browsing starts with a deliberate action. NO BUSINESS MODEL Nul is free with no ads, no subscriptions, and no data collection. You using this and getting some of your mind back is our payment.

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.
