Built my own model-agnostic AI workstation because I was tired of platform lock-in — free, BYOAK, open source

Key Points

The article describes a new “model-agnostic” AI workstation UI called Architect's Domain designed to reduce context rebuilding when switching between providers and models.
It includes persistent workspace environments with pinned context, imported files, and notes, aiming to make setups portable across different LLMs.
The system provides manual memory curation, showing memory fragments during chat and letting the user approve or reject what gets remembered.
It supports character/persona creation via file injection (e.g., .txt as system context) and offers provider switching across services like OpenRouter, Venice.ai, and DeepSeek.
The project is open source and runs fully static with BYOAK (user-provided keys and data), and is implemented in plain JavaScript/HTML/CSS for easy deployment without framework bloat.

Tired of rebuilding context every time I switched models. Tired of my personas living inside OpenAI's walled garden. Built something to fix it.

**Architect's Domain**, a workstation UI that sits on top of any provider.

Core features:

- **Workspace system**, persistent environments with pinned context, imported files, notes. Think Claude Projects but provider-agnostic

- **Manual memory curation**, fragments surface during chat, you approve or reject what gets remembered. No silent auto-memory

- **Character/persona system via file injection**, load .txt files as system context. Works with character cards, lorebooks, personality files, anything

- **Provider switching**, OpenRouter, Venice.ai, DeepSeek. Swap models without losing your setup

- **BYOAK**, your keys, your data, runs fully static

No React, no framework bloat. Vanilla JS + CSS + HTML. Deployable anywhere.

I use it daily for prompt engineering and RP character testing across different frontier models. The workspace + memory combo is what makes it actually useful vs just another chat wrapper.

Feedback welcome! especially from people who've tried similar setups.
