Brainglue
Brainglue was a conversational AI client built for creative professionals and knowledge workers who wanted more steerable outputs with less re-prompting. It combined fine-tuned assistants with direct access to frontier models like GPT-4o, Claude 3.5, Gemini, and Llama 3.1 inside one fast chat interface. The service is no longer available; brainglue.ai now displays a shutdown notice thanking users for supporting the team's AI experiments.
Instead of treating every prompt like a generic chatbot request, Brainglue routed queries to specialized workflows through slash commands. Assistants like /write, /journey, /brainstorm, and /product-writer were designed for professional writing, user journey mapping, ideation, and product documentation. Users could also jump between foundational models without leaving the same conversation.
A single subscription aimed to replace juggling multiple AI accounts by bundling unlimited access to flagship models from OpenAI, Anthropic, Google, Meta, xAI, Stability AI, Black Forest Labs, and Perplexity. Memory documents let users store recurring context and pull it back into prompts, while workflows like /journey could return visual artifacts instead of plain text.
The product targeted designers, UX writers, product managers, and other creative professionals who needed a thought co-pilot rather than a one-size-fits-all chat box. Brainglue AI, Inc. built it as a productivity-focused experiment in augmenting strategic thinking.
