“Complete sanity saver when it comes to YouTube. Not being able to listen to a single song hands-off without listening to two 5 minute long ads on each song was agonizing. This app has made YouTube usable again. Cannot express how much of a relief this has been, especially for those who use it while working and can't stop to skip 5 ads in a row on every 2 minute long video, but don't want to buy premium for something that used to be free for years. THANK YOU!”

“Unfortunately it’s currently nowhere near as good as a ChatGPT Plus subscription. It doesn’t have any extensions for producing finished applications or documents, so you’re forced to manually go back and forth from chat if you actually want to build or refine something. The daily/weekly usage limits are also quite low if you’re using the more advanced models. Just sending a basic query to GPT 5.6 Sol might use up 2-3% or more of your daily quota, whereas basic chat queries don’t even eat”

“For obvious reasons the security & elimination/minimization of the non-stop bombardment of absolutely useless ads. I currently use the free version, however, if they suddenly announced a small fee for the "free"version I would undoubtedly pay for the service!! I'm not asking for that I'm just saying!! Thank you for providing the service.”

“tl;dr —duck.ai allows AI companies to store your chats, process them for profit, and build a personal, permanent profile about you based on metadata and inferences extracted from the content of your conversations. —[edit] In comments responding to this Reddit thread, DuckDuckGo outright admitted that models can and do access and retain your user data, even when accessed through duck.ai. DDG has refused to specify what data is accessed and kept, and what purposes user data can be used for. —DuckD”

“Duck.AI users have probably noticed the new usage meters popping up as well as the ability to use weekly limits if your daily limit is reached. This has coincided with a dramatic decrease in limits of use on my account and would like to hear if others are experiencing the same. For the past few days daily limits are reached with 10-12 prompts (no, I’m not a coder) using Claude Opus, which is absolutely ridiculous for a premium paid plan. I also noticed they decreased the specs for Pro from 3x Pl”

“I've used this for several years, and it improves in protection, especially from cookies and other unwanted tracking, every year. I pay for a different, separate security program that also covers my laptop, and I'm debating whether to renew it because after Duck does its thing, my security reports show there's not a lot for that program to clean up or screen out. Chrome's search results are better sometimes, but Duck's privacy protection and AI responses are far better for my needs.”

NEGATIVE google_play

“The version 5.295.2 is awful. Very often when you search for an item, the address bar completely disappears, making it worthless. You must escape from the app and relaunch in oder to get the address bar displayed. Simply closing it won't regenerate the homepage. My previous review was 3 stars. I will be hoping that this gets straightened out.”

POSITIVE google_play

“I wish I had switched to DDG sooner! I was a 10+ year Firefox user, and lately their backtracking on privacy disappointed me, among other changes they made. I heard DDG had had a surge of popularity and was very private so thought "why not?". And now I am never going back! I love how much more private it feels - the tracker blocker, built in ad-blocker, the option to remove AI, the FIRE button to instantly erase all your data and tabs. The layout is customisable too, so very easy to get used to.”

POSITIVE google_play

“Exceptional protections, fully functioning browser, alright search results. I love that I'm not being tracked, the lack of ubiquitous ads, and the fact that it actually loads every single page I've been to correctly (not gonna call anyone out. You know who you are.) Search results with DDG are not quite as good as using Google, but for most searches, it's acceptable.”

“Never too late to quack: Now that Google sucks up to a deranged damaged demagogue, I deleted it and will only search with DuckDuckGo. I like the privacy that comes with it, ease of use, and not supporting a company that sold its corporate soul.”

“Good app, good ai, relatively secure. There is one slight problem.... when you go to clear the list of downloaded files, IT ACTUALLY DELETES THEM. I just lost a month's worth of downloaded files, all because there's no "clear" list of downloaded files. please change this.”

NEGATIVE app_store

“Okay I guess: I mean…still has AI baked into it, doesn’t it? So not really all that it’s cracked up to be. Keeps asking me to upgrade…and limits how many sites I can block? Why don’t you let ME decide what slop, if any, is worth reading? This doesn’t actually do what it wants you to believe it does, and doesn’t even summarize “blocked” trackers. Hard to see the value here.”

“New update is so annoying: Stop trying to cram the AI feature down my throat. I want to search not get taken to an AI chat where nothing even loads because you want me to pay for the feature”
