Your brand, in every AI answer.

Siftie builds and tests a prompt portfolio across different LLMs — from sources you already have. Drop in your brand brief, chat with the agent, and ship a tested set of prompts ready for ChatGPT, Gemini, Claude, and Perplexity.

How it works

From sources to a tested prompt portfolio in three steps.

  1. 01

    Add sources

    Drop PDFs, paste URLs, or share Google Docs and markdown notes. Gemini indexes each one into a structured ContextDoc the agent can quote in chat.

    PDF · URL · Doc · Markdown

  2. 02

    Chat with the agent

    Answer six tailored questions about your brand, then refine the context conversationally. The agent searches the web when your sources fall short.

    Interview · Refine · Web search

  3. 03

    Get a tested portfolio

    Siftie ideates ~24 prompts, runs a multi-LLM Council to pick the strongest, and tests each one against live ChatGPT / Gemini / Claude / Perplexity baselines.
