Most people who land on this page are asking a question that doesn’t need asking, and the old version of this page asked it too. You don’t have to choose between Brave and dassi. dassi installs from the Chrome Web Store into Brave the same way it installs into Chrome or Edge, and it works in your normal Brave profile. So the real comparison is narrower: Leo, the assistant Brave builds in, against dassi running in the same window.
What Leo is for
Leo is good at reading. Open a long article, a PDF or a doc, ask Leo to summarize it or explain a paragraph, and it answers in the sidebar. The free tier doesn’t make you create an account, Brave says Leo doesn’t keep your chats or train on them, and it’s in Brave for Android and iOS as well as desktop. Leo Premium ($14.99 a month or $149.99 a year) raises the limits and adds models, and if you’d rather plug in your own model, local or remote, the bring-your-own-model screens got a redesign in Brave’s September 11 desktop release.
None of that is what dassi does. dassi is for the moment after the reading, when somebody has to go and do the thing: fill in the supplier form, copy the order numbers into the sheet, update the CRM record.
Brave’s own agent test
Brave has an agent too. Leo’s AI browsing takes a task, opens pages and clicks through them by itself. Brave moved it out of Nightly on May 5, 2026, and it’s now an early test in every release channel, off by default, switched on at brave://flags and started by hand each time. Brave is unusually frank about it. Its announcement calls agentic browsing “inherently dangerous” and “a work in progress,” and says the safeguards (a second model that checks the first one stays on task, plus no access to non-HTTPS pages or sites flagged by Safe Browsing) “do not eliminate risks such as prompt injection.”
We like that frankness. We’d still wait for it to leave the flags page before building a weekly routine on it.
Logging in
This is where the two designs part ways. Brave runs AI browsing in a separate profile, and in its words, “cookies, logged-in state, caches, and other site data do not cross profiles.” That’s on purpose, since an agent that can’t see your sessions can’t wander into your bank or your inbox. It also means the agent starts without your work logins, and Brave’s post doesn’t describe signing in to sites from inside that profile.
dassi works in your regular Brave profile, on the sites you’re already signed into. When a session has expired, it signs in with whatever Brave’s password manager autofills, so the password stays in the password manager instead of going into a chat or into dassi’s settings, and you type the 2FA code yourself. The safety comes from somewhere else: dassi pauses before any action you’ve flagged and asks you when it reaches a decision only you can make.
When to choose Leo
If what you want from AI in Brave is help reading, Leo is already there and the free tier costs nothing. Pick Leo, too, if you’d rather an agent never touched your logged-in accounts. Brave’s isolated profile is a reasonable line to draw, and some people should draw it.
When to choose dassi
When the job sits behind a login and comes back every week. You describe it in plain English or do it once while dassi follows along, save it as a workflow, and rerun it whenever you like, or on a schedule as long as your browser is open when it’s due. You pick the model (Claude, GPT, Gemini, Grok, DeepSeek, Kimi, something on OpenRouter, or a local one) and pay $10 a month with your own key, or $25 to $300 a month on a plan with credits. The instructions and page content go to whichever provider you picked, through dassi’s relay if you use included credits.
Nothing stops you keeping Leo in the sidebar for reading while dassi does the typing, either. They don’t get in each other’s way.
