💡 What You Will Learn
An AI ad copy generator you control: local LLM + your product facts + angle prompts. No subscriptions, no generic SaaS output.
📜 Table of Contents
Most AI ad copy tools generate the same five templates. The workaround is to build your own generator around a local model and your actual product facts - the output stops being generic the moment the input stops being generic.
The Workflow
Step 1: write a facts file - price, guarantee, differentiators, testimonials (real ones). Step 2: build a prompt that forces the model to use only those facts. Step 3: generate 20 variants per angle (benefit, pain, social proof, urgency). Run it locally with Ollama (177,874 stars) or any open model; DeepSeek-V3 (104,114 stars) is a strong open-weight option for copy quality.
Why It Beats Templates
SaaS tools optimize for demo-ability, so every output smells the same. A facts-driven local generator produces copy your competitors literally cannot have, and it costs zero per run. The one skill to learn is prompt iteration: 10 minutes of refining angles beats 10 more template tools.
FAQ
Q: Is local model copy good enough?
A: For short-form ads, yes - modern open models write punchy headlines; always run a human edit pass.
Q: Can I generate at scale?
A: Yes - batch prompts through one-api (36,211 stars) or direct local inference; 100 variants costs nothing locally.
