X Search Assistant targets researchers, marketers and power users who rely on X search but dislike building complex operator strings by hand. The extension adds a prompt box on top of X; you type something like "tweets by dejavucoder about system design in 2024 with more than 10 likes" and the model produces an equivalent query such as from:dejavucoder (system design OR architecture) since:2024-01-01 until:2024-12-31. The generated query is then executed on the real X web interface in a new tab, so results come straight from the platform.
The tool is model-agnostic. You bring your own API key from OpenAI, Anthropic or OpenRouter, and because the underlying system prompt is elaborate, even smaller and cheaper models such as Claude Haiku or Gemini Flash produce usable queries. Useful conveniences include a history of recent English-input/query pairs, an editable and transparent default prompt, and shortcut flags like -l for the latest timeline and -idk for when you are unsure about a username, plus a Ctrl+Shift+S keyboard shortcut.
It is an independent third-party extension and is not affiliated with, endorsed by or published by X Corp. It only generates and launches search URLs, so it does not scrape or store tweet data on its own servers. Because it is distributed free through the Chrome Web Store and asks users to supply their own model credentials, your only running cost is whatever your chosen LLM provider charges per request.
