Complex coding, have any of the following help you and then import the code into Cursor as a .md file. Then tell cursor you had an external llm assist, and to review the instructions and the code.
Make sure you have the External LLM give implementation instruction.
I use Anthropic Opus 4, however the following have a free accounts:
- Claude
- Perplexity
- Grok
- Manus
- DeepSeek
There are even more than this if you want to download Ollama or LM Studio.
