I don’t like the duck.ai interface much (choosing a different LLM is not easy once you’re already in a conversation), but I use it a lot more than I use the DuckDuckGo search engine (the results from the latter aren’t great).
Just like with DuckDuckGo search, where I start a search and then use the !g bang command to go to Google for better results if needed, I try duck.ai and then move to ChatGPT (without any account) when even the best models in duck.ai aren’t good enough.
For most simpler queries though — where I’m just looking to learn a bit about something as opposed to finding a solution for a specific (more complex) question or problem — duck.ai with its GPT 5 models are more than adequate (even the 4o mini is fine).
You can search "!w Gabriel Weinberg" and it will open the Wikipedia article because of the leading exclamation mark and w. If a site changes their search url, you can submit the precise new pattern they should use for a redirect. If a new service pops up, you can use the same form to request a new search prefix. These form submissions could give someone at DDG an easy interface to verify quickly and approve or reject them.
These form submissions get ignored and have been for years at this point.
Just for anyone else who isn’t aware, the bang commands can be anywhere in the search string, and need not necessarily be at the beginning.
All these queries will take you to Wikipedia for the term:
"!w Gabriel Weinberg"
"Gabriel !w Weinberg"
"Gabriel Weinberg !w"
Many a times when I find the default DuckDuckGo search results inadequate and want to go to Google search, I just put a “!g” as a separate term anywhere within the search string and hit enter. This is especially useful on mobile where the search string may be a lot longer than the visible text box and I can’t be bothered to move the cursor.
