Carry your conversation from one AI to another — without losing the thread.
Sweater is a Chrome extension (Manifest V3) that captures the context of an AI chat, compresses and enriches it, and lets you "wear" it into a different AI — ChatGPT, Claude, Gemini, Grok, Perplexity, Groq, and more — so you never have to re-explain yourself.
- One-click capture of the current AI conversation into a portable capsule.
- Smart Compress: multiple compression modes (Clean Chat, Transcript, AI Smart Memory) to cut token usage while preserving intent.
- Context Quality Score and auto-detected conversation domain/tags.
- Smart Save Checkpoints — extract durable state (goals, decisions, open items) instead of raw transcript.
- Summary, Insights, Translate (11+ languages), and Ask AI — run directly on the captured context.
- Bring your own key via multiple provider integrations (OpenAI, Anthropic, Gemini, Groq, DeepSeek, Mistral, OpenRouter, NVIDIA NIM, local Ollama/LM Studio, and more).
- Try More Models — test additional providers/models without changing your primary configuration.
- Wardrobe: your saved capsule library — tag, search, edit, duplicate, and manage every captured context.
- Wear: inject a saved capsule straight into any supported AI's input box (or attach as a file) to resume the conversation instantly.
- Select any text on a supported AI site and launch Mini Sweater — a floating, assistant scoped to just that selection.
- Run quick actions (Explain, Summarize, Rewrite, Fix Grammar, Change Tone, Review Code, and more) or have a follow-up conversation about the selected text, without leaving the page.
- Manage API keys per provider, set a default translation language, toggle Smart Save/Smart Naming, and configure Try More Models slots.
- Export/import your full capsule library as backup.
