Oasis Browser for Mac - A privacy-first AI browser you can train anonymously

@pallavi_m18 I hope we can deliver on your dream. What are your dream workflows? What are the series of actions you find yourself doing in the browser? If you could wave a magic wand and have Oasis do anything for you, what spell would you cast? These are the things we'd love to learn more about. When you let us know, we can build in new features that makes it a reality :)

@nlokesh9 Thanks for sharing more about our Journey, Lokesh! The no-ads experience also somewhat snuck up on me. The idea was to always make it add free, but only through sitting in user interviews with Archana and BD, did I realize that no-ads and privacy ranked just as high on the priority list for many users as privacy, anonymity, and data security. We're still learning now with all the responses in this thread!

@shivam_jaiswal21 Thanks for sharing your thoughts, Shivam! That shared-profile / sync-leaking-context problem is exactly the kind of thing we had in mind when we separated “your browser” from “how we improve the assistant.”

Short answer: the assistant is not local-only. When you use Oasis Assistant, prompts and replies go to cloud LLMs (routed via our backend/proxy — e.g. Gemini through Supabase Edge). That’s separate from “anonymous training,” which is about whether improvement data is tied to your account, not whether anything leaves your machine.

What stays on your device (by default)

• Browsing history, bookmarks, and the local memory / semantic search index (including on-device history embeddings)

• Saved passwords in Firefox’s encrypted Login Manager — not in assistant memory or training payloads

• Day-to-day browsing profile — we’re not building a “shared browser profile” that syncs your full context to ads or a central browsing graph

What leaves the device when you use the assistant

• Inference: Your message, the model’s reply, and whatever context the agent attaches (e.g. active tab URL/title, tool results, and sometimes page text if you use summarize / page-grounded tools) — that goes to the remote model so the assistant can answer.

• Product improvement (optional logging): With “Personalize Oasis Assistant with my account” turned off (the default for new profiles), we still log assistant interactions to improve the product, but user_id is null — no email, no account block in the payload. “Anonymous” here means not linked to your identity in our DB, not “nothing leaves the device.”

“Anonymous training” specifically

That’s the thumbs up/down + comment flow on replies. You can submit training as anonymous (feedback_events without your user id) or personalized (linked to your account). That’s a second knob from the Privacy setting above — same words, different tables. Either way, you’re giving us signal on what worked; anonymous mode just keeps that row off your account.

What we’re not doing

• We’re not claiming a fully on-device model for chat today (perhaps in the near future!)

• We’re not claiming zero data when the assistant runs — cloud inference + (by default) anonymous interaction logs.

• We’re not uploading your whole browsing history as a training corpus; improvement signal is assistant-shaped (prompts, responses, tab context when you’re in the assistant, tool traces).

For B2B CS workflows: Oasis is closer to “your machine holds the messy browser state; the assistant only sees what you invoke and what tools pull in for that turn” than to “train a shared synced profile.” If you need air-gapped / no cloud at all, we’re not there yet — we’d say that upfront.

Happy to go deeper on any layer (telemetry JSON shape, user-initiated training vs telemetry data from general llm usage, or what’s local for search vs chat).

Just curious, what other aspects are you and your team thinking about? I love this space and these conversations :)

@saksham0403 "Simpler and more natural" has been our North Star from Day 1. That you feel this way makes us feel a degree of fulfillment in achieving our mission. I'm flattered that you're excited about the direction we are taking. While we've tested other ai browsers on the market, yes, we have noticed that some feel like some added another layer of complexity to the user experience, rather than facilitating deep work. These are all positive things, but if you have any constructive criticisms or things you feel like we can improve on for you, please let us know!

@rashmilamitra we're honored that you've trusted us to give Oasis a try over the last few weeks, and we're delighted to hear that you feel calmer while browsing. I just wanted to emphasize that we are committed to preserving this calm and double down on Oasis as a refuge for you to traverse the Internet and do deep, meaningful work. I'm excited to see what you cultivate and build in your Oasis.

We're also looking for negative feedback of any type. If you ever notice an issue that makes you cringe, whether it's a feature or user experience element, please don't hesitate to give us a shout so we can smooth that out ASAP for you :)

@jaideep_kulkarni it's wonderful to hear that you feel like your experience and workflow have become more structured with Oasis. This is a goal we set out to achieve when we decided to build it, and the fact you feel this way means we are moving in the right direction. We feel like we are just getting started with this, so if you have any wish-list enhancements we can make to the built-in AI, we'd love to know. One that comes to my mind is attacking more complex workflows: if there are more abstract or complex, multi-step workflows you wish you'd be able to do, we'd love to learn more about what those are. We have built a solid foundation and architecture with Oasis AI, and we see a wide open blue ocean ahead to rapidly expand the capabilities of the built-in AI. I'm frothing at the mouth to add more XD

@krishna_samhitha You should try out the "create tab group" and "add this tab to tab group" features! I also switched on "Vertical tabs" by right clicking tabs. I feel like this makes my experience calmer. If you have any wishlist commands holler them. If you had a magic wand and could say anything out loud to manage and reorganize your tabs like magic, what are the things you'd say?

@arch14 are there any new types of workflows you’d like us to introduce? Thanks for sharing the positives so far. We still feel like we have a lot of room to improve. If you could wave a magic wand and have Oasis do anything for you, what would you say?

@sonali_ankolikar Don't you worry, Windows version pipeline is being wired up as we speak. I can't wait for you to dive in

@rashmikadwani it's definitely early, and we feel like we have a wide open frontier to explore. Oasis can be expanded significantly. If you had to say, what could we change or improve? Do you have suggestions? Beyond what you've shared, is there something else we haven't touched on yet that you'd ideally want in Oasis to make your life easier?
