Tierpik: the right AI model, set up for you

Picks the right AI model and setting for your task, then sets it up in ChatGPT, Claude, Gemini, Grok or Perplexity.

Stop burning your AI usage limits on the wrong model. Tierpik tells you which model and setting to use for what you're about to ask, based on the plan you actually pay for. Then it sets it up for you. WHAT IT DOES A tip while you type: in ChatGPT, Claude, Gemini, Grok and Perplexity, Tierpik reads your draft and tells you when a lighter model will do the job, or when the task needs a stronger one. One-click switch: press Switch and Tierpik changes the model (and Claude's effort level) for you. Your draft stays exactly as it is. Tierpik never presses Send. Set up from tierpik.com: type a task on tierpik.com, press "Set up in ChatGPT" (or Claude, Gemini, Grok, Perplexity), and Tierpik opens a new chat, picks the model and pastes your prompt. Plan-aware: tell Tierpik your plans once (Free, Plus, Pro, Max, Workspace…) and its picks only use models you actually have. Usage meters: a badge shows how close you are to your tightest limit. PRIVATE BY DESIGN Everything runs in your browser. Your drafts and prompts are never sent to Tierpik or anyone else. No account, no sign-in, no tracking, no ads. Tierpik only runs on the five AI sites above and on tierpik.com. Tierpik is independent and not affiliated with OpenAI, Anthropic, Google, xAI or Perplexity. Model names belong to their owners. Plans and limits change often; Tierpik's data is dated and updated regularly.
