ChatGPT browser freezes and crashes on long conversations (300+ messages)

Heavy ChatGPT users experience severe browser lag and crashes when opening conversations with 300+ messages, as the interface renders the entire DOM at once. The problem scales with usage — power users who rely on ChatGPT most are penalized hardest. Virtual scrolling is a proven fix but OpenAI has not natively implemented it.

ChatGPT Becomes Unusably Slow in Long Conversations

ChatGPT degrades severely — lag, freezes, excessive RAM usage — in conversations exceeding roughly 100 messages. The browser must render and hold the full conversation DOM, creating a structural performance ceiling that affects anyone using ChatGPT for extended research, coding, or writing sessions. OpenAI has not addressed this natively, leaving a persistent gap for third-party tooling.

AI assistants lose all user context between sessions

Every new AI chat session starts completely blank — users must re-explain their role, tech stack, preferences, and communication style from scratch. This stateless design degrades response quality for power users and creates a compounding productivity tax the more someone relies on AI tools daily. The problem is structural to current LLM chat UX, not a surface-level bug.

Premium Ad Blockers Have Become Bloated and Subscription-Gated

Users frustrated with dominant ad blockers find them increasingly heavy, feature-bloated, and pushed toward paid tiers for full functionality. The original value proposition of lightweight install-and-forget ad blocking has eroded as incumbents monetize their user bases.
