About

Kerlig is an AI-powered writing assistant for Mac that helps users save time and improve their communication at work by integrating with all apps. It supports multi-language features and allows you to proofread, summarize, translate, and extract key points from PDFs, documents, and web pages. Custom Actions and presets make it adaptable to your workflow. Custom Actions allow for editing prompts to make the AI model perform exactly what you need. Invoke them with a single click or a keyboard shortcut. Presets are personalized settings for AI models that give them a specific personality and guide their actions based on your preferences. For example, they can help the AI write emails in your style or take on roles like a software engineer or copywriter. Kerlig supports over 350 AI models, including providers like OpenAI, Google Gemini, Anthropic Claude, Perplexity, AWS Bedrock, OpenRouter, and more. It also supports running local models via Ollama and LM Studio integrations.

About

PromptUnit cuts your AI API bill without hurting answer quality. Inferio, the engine inside PromptUnit, checks every request your app or agent sends. When a cheaper model is just as good for that request, it uses it; otherwise the request goes to the model you asked for. If you connect keys for more than one provider, the cheaper model can be at another of them. Setup is two settings: point your AI API address at PromptUnit and add your PromptUnit key. Your own provider keys stay yours. Works with OpenAI, Anthropic, Google Gemini, Groq and DeepSeek keys, and with your own OpenRouter key, plus tools like n8n, Open WebUI, LibreChat and Dify. The dashboard shows every request: the model asked for, the model that answered, what it cost and what it saved. It also groups requests into the steps of your app and shows what each step costs. Pricing: the first $5 of savings is free, then 20% of what PromptUnit saves you, billed weekly. Nothing if it saves nothing.
