Gremllm — an Idea Development Environment

Slow thinking with AI.

Gremllm is a desktop workspace for working on high-value documents with AI — investment memos, strategy docs, product requirements. Documents that carry your name, get scrutinized, and usually take several experts to produce.

You direct; the AI writes. You never type into the document — every change comes from the AI, and you accept, reject, or redirect each one. Select text to focus the next round. Your judgment shapes the document; the AI does the typing.

Status

Early. Not ready for real work.

Today:

• Document panel with live markdown rendering
• AI assistant via the Agent Client Protocol (Claude, through claude-agent-acp)
• Pending diffs appear inline with accept/reject controls
• Selected text stages as structured context for the next prompt
• Workspaces are portable folders of markdown files — today one document.md per workspace

Next:

• Quick-action agents: launch a purpose-built topic from a selection (validate, research, simplify)
