Compress prompts, save tokens & inject memory into ChatGPT, Claude, Gemini + 12 AI platforms. Privacy-first. Works automatically. AETHER reduces the token cost of every AI conversation by compressing your prompts, remembering your context, and catching duplicate questions — automatically.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PROMPT COMPRESSION Compress any AI prompt before sending with one click. Three modes to match your needs:
Fewer tokens sent means less money spent on every message, whether you are using a paid AI subscription or API credits.
MEMORY BLOCKS — AI THAT REMEMBERS YOU Save your tech stack, coding style, company voice, or project context as a reusable Memory Block. AETHER injects it automatically into every new chat so you never waste tokens re-explaining yourself at the start of each conversation.
SEMANTIC CACHE — STOP PAYING TWICE When you ask something similar to a question you have already asked, AETHER recognizes it and offers the cached answer instantly. Zero tokens spent. Zero API cost.
TOKEN SAVINGS DASHBOARD Track exactly how many tokens and how much money you have saved over time. All data stays on your device — nothing is sent anywhere.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WORKS ON ANY AI CHAT PLATFORM ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
AETHER activates automatically on any AI chat website you visit — including ChatGPT, Claude, and Gemini — with no manual setup or configuration required. New platforms are detected automatically without needing an extension update.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BUILT FOR DAILY AI USERS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
If you use AI tools every day you are likely wasting tokens on:
AETHER is particularly useful for developers using AI coding assistants, writers using AI for content creation, researchers running multiple AI conversations, and anyone paying for an AI subscription who wants more output for less cost.

No account required. No API key required. Works immediately.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY FIRST ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Everything runs locally on your device. Zero telemetry, zero data collection, zero external servers. Your prompts never leave your browser except to the AI you chose to talk to. AETHER only reads the text in the input box before you send it — it cannot see AI responses or your conversation history.
