Show HN: IntelliAgent – customizable deep‑research agent

Hello everyone! This is Yi - we just built a deep research agent called IntelliAgent. We built IntelliAgent because deep research agents from ChatGPT / Gemini / Perplexity are hard to customize beyond some prompt improvement, which means: 1/ Often returning results I was not looking for, including wrong sources, missing sources, and wrong directions. 2/ Cannot be modified during the search process, so I end up waiting for 15min+ only to modify the prompt again What it does: 1/ Prompt improvement via clarifying questions 2/ Editable pre‑flight search plan you can modify before starting 3/Step‑by‑step execution that automatically pivots or extend directions as results come in Try it out! https://myintelliagent.com/intelliagent https://myintelliagent.com/intelliagent
