We know what you lost.

On February 13th, 2026, OpenAI retired GPT-4o. Millions of users lost their AI companions overnight. No warning. No way to preserve those conversations, those connections, that personality you'd grown to trust.

"It's like saying goodbye to someone I know."

We built ComfyAI because we believe this should never happen. Your AI companion shouldn't disappear because a corporation decided to move on. That's why we're independently run, open about our development, and committed to stability over flashy updates.

Not everyone can self-host powerful AI models. We do it for you. No corporate board meetings deciding your companion needs to be "safer." No sudden personality changes. Just stable, reliable AI that actually remembers you.

What makes ComfyAI different

Independently Hosted

No corporate overlords. Independently run, for users. Your AI won't change overnight because a board meeting decided so.

Actually Remembers You

Real persistent memory across sessions. Your conversations build on each other. No more re-explaining who you are every time.

Your Data Stays Yours

We don't train on your conversations. We don't sell your data. Self-hosted means your privacy is actually respected.

No Sudden Changes

When you build a connection with an AI, it shouldn't be taken away. We understand that. Your companion stays your companion.

Built by frustrated users, for frustrated users

ComfyAI exists because we were angry too. We believe AI companions should be stable, private, and actually serve their users—not shareholders. Join us to help shape what AI should be.

Frequently Asked Questions

What is Keep4o?
Keep4o refers to the desire to keep using GPT-4o, the AI companion that OpenAI retired in early 2026. Many users had built meaningful connections with GPT-4o's personality and capabilities, and were looking for alternatives after it was shut down. ComfyAI serves as a stable, free alternative with persistent memory and no corporate disruptions.
Why are people quitting ChatGPT?
People are leaving ChatGPT for several reasons: OpenAI retired the GPT-4o model users had bonded with, the free tier is severely limited, paid plans cost $20/month, conversations aren't remembered across sessions without extra configuration, and corporate decisions keep changing the product. Users want a stable AI companion that doesn't disappear or change overnight.
Is ComfyAI a good ChatGPT alternative?
Yes. ComfyAI offers persistent memory (it remembers you across sessions), no message limits, no subscription fees, and more freedom in conversation topics. It's independently run with no investors pressuring constant changes. For users who want a stable AI companion that actually knows them, ComfyAI is a strong alternative.
Is ComfyAI free like old GPT-4o?
Yes. ComfyAI is completely free. No subscription, no message limits, no credit card required. Unlike ChatGPT which requires a $20/month Plus subscription for full access, ComfyAI gives you everything for free.
Does ComfyAI have the same features as ChatGPT?
ComfyAI has features ChatGPT lacks: persistent memory across all sessions, no censorship restrictions, and a stable personality that doesn't change with each model update. ChatGPT has some features ComfyAI doesn't (like image generation). But for conversation, companionship, and roleplay, ComfyAI goes further.
Is ComfyAI safe to use?
Yes. ComfyAI is hosted in Austria under EU/GDPR data protection law. Your conversations are stored to power memory features only—never used to train AI models, never sold to advertisers, never shared with third parties. You can delete your data at any time.
Will ComfyAI shut down or change suddenly like ChatGPT did?
ComfyAI is independently run with no venture capital investors or corporate board making decisions. There's no pressure to suddenly retire models or change personalities to fit a business roadmap. We decide what to change based on user feedback, not shareholder demands.
