Terse — Token Optimizer for LLMs

Terse compresses your AI prompts in real-time, saving tokens and reducing API costs — without losing meaning. How it works: Terse runs a 20+ technique optimization engine directly in your browser. It removes filler words, politeness padding, hedging, redundant phrases, and compresses whitespace — all while preserving the meaning of your prompt. Your text never leaves your browser unless you choose to sign in. Three optimization modes: - Soft — Typo correction + whitespace compression. 100% meaning preserved. - Normal — Removes fillers, politeness, hedging, meta-language, shortens phrases. - Aggressive — Maximum compression. Abbreviations, article removal, telegraph style. Works with every AI chat: Terse works on any AI chat or agent — if you can type into it, Terse can optimize it. Features: - One-click Capture & Replace — reads your prompt, optimizes it, writes it back - Live monitoring — auto-optimizes as you type (optional) - Manual paste mode — paste any text to optimize - Token counter — see exactly how many tokens you save - Technique tags — see which optimizations were applied - 8 beautiful themes (Lime, Lavender, Coral, Teal, Midnight, Rose, Sage, Sand) - Keyboard shortcuts (Cmd+Shift+T to optimize, Cmd+Shift+R to replace) - Undo — instantly revert any replacement - All optimization runs locally in your browser — fast and private Saves real money: If you use AI APIs, every token counts. Terse typically saves 15–40% of tokens per prompt, which adds up fast when you're paying per million tokens. Privacy first: All optimization happens locally in your browser. No text is sent to any server. Optional sign-in enables usage sync and subscription features.
