Appaca is the AI workspace for operators. Build internal tools and AI co-workers powered by the model that fits your use case - connected to your real data and ready for your whole team.
Describe it, and it's built
Tell the Appaca agent the internal tool you need - a support bot on Claude, a report generator on GPT-5.5, a writing tool on Gemini - and it builds a working app. No code, no API keys, no deployment.
Switch models without rebuilding
Start on one model, test the same tool on another, and keep whichever performs better for your specific use case - the rest of your app stays exactly as it is.
Automated for the whole team
Schedule tools to run on autopilot - daily digests, weekly reports, real-time triggers - and share them with your whole team from one workspace.
Describe it, and it's built
Tell the Appaca agent what your team needs and it builds a working app powered by the model you choose - connected to the tools you already use.







FAQs
Start with the task - what kind of output do you need, how long are the inputs, and how often will it run? For complex reasoning tasks like legal review or research, frontier models like Claude 4 Opus or GPT-5.5 lead. For high-volume, lower-stakes tasks like email drafting or summarisation, smaller fast models cut costs significantly. Each use case page ranks the top five models and explains what evaluation criteria matter most.
Yes. Frontier text models like GPT-5.5 and Claude 4 Opus perform strongly across most text-based use cases - coding, writing, legal, research, and customer support. The real trade-off is cost: if you run high volumes of a simpler task, a specialised or smaller model will often be more cost-effective than using a frontier model for everything.
Not with Appaca. Describe the internal tool your team needs - a customer support assistant, a contract summariser, an email drafter - and the Appaca agent builds it as a working app powered by the model you choose. No API keys, no code, no deployment.
Appaca is an AI workspace for operators. Describe what your team needs and get a working app with a built-in database, team access, and no coding required. It supports every model in this directory, so your tools always run on the model that fits the task.
