What DeepSider is
DeepSider is an AI assistant that sits in your browser sidebar. It is built on the DeepSeek R1 and V3 models and is described as free and open-source. With a clean interface and fast replies, it helps with work, study, and daily browsing. You can ask questions, write content, translate text, generate code, and interact with documents and images. A highlight tool lets you select text on a page for quick translation or summary, so you do not have to leave the tab you are reading, and an online search option pulls in fresher answers.

What to watch out for
As an open-source tool, it can change or break when updates ship, so keep backups of important work and install updates carefully. Its answers are not always correct, so verify facts before you rely on them, especially for code. It also depends on the underlying models, so availability and quality can shift if those models change or if the project is not maintained. For best results, start with a small test file and review the output carefully before working on anything important. Free tiers can change over time, so it is worth checking the current limits on the official page before you rely on the tool daily. If the result is not quite right, try adjusting your input description or settings and run the task again.
