# Avgidea, Inc.

> Avgidea, Inc. is a Japan-based software company. Its main product, Greenative Studio, is a Private AI Workbench for Mac: a macOS desktop app that runs local large language models (LLMs) and coding agents entirely on Apple Silicon Macs, so prompts, business documents and source code never leave the device. It is built for small and medium-sized businesses and professionals who want to use generative AI while keeping control of their data (data sovereignty). A Free plan is available permanently with no credit card required.

## Key facts

- Platform: macOS on Apple Silicon (M1 to M5). Also runs on cloud-hosted Macs such as Amazon EC2 Mac instances.
- Fully local inference: no data is sent to cloud AI services. Suitable for confidential client documents, internal data and proprietary code.
- Local models: commercially licensed open models including Gemma, Phi, Mistral, Qwen and NVIDIA Nemotron.
- Free plan: private chat with the Phi-4-mini local model and tool calling, free updates, no time limit, no credit card required.
- Pro plan (US$18/month or US$180/year): adds local coding with LLMs, bundled MCP servers and local fine-tuning with your own data. Fixed price with no token-based billing for local models.
- Local coding: works with Claude Code and compatible coding agents using locally hosted models, so source code stays on the Mac. Larger coding models such as Nemotron 3.5 Lightning are recommended with 32GB or more of memory.
- Documents: file handling and document conversion, such as PDF to PowerPoint, Word or Excel.
- Business data: can connect to databases and cloud storage through Greenative Platform (optional).
