Tabbit AI is a free agentic web browser built by Meituan's GN06 team — the group formerly known as Light Year — that adds an AI chat sidebar, a task-running Agent, and access to 10+ language models directly into the browser itself. It runs on macOS and Windows, migrates your bookmarks and history from Chrome, Safari, or Edge in one click, and lets you switch between models like DeepSeek, Claude, and GPT mid-conversation instead of locking you into one vendor.
Short answer: Tabbit AI is a free agentic browser from Meituan (macOS 12+ Apple Silicon, Windows 10/11) with a chat sidebar, an Agent that automates multi-step tasks across tabs, and 10+ selectable models. The Free and Standard tiers cost nothing — Standard unlocks 10x usage by setting Tabbit as your default browser. Pro adds top-tier models and 100x usage for $30/month.
I installed Tabbit AI on a Windows machine, migrated an existing Chrome profile, and ran its Agent against a handful of real research and form-filling tasks over several sessions. In my testing, the browser itself feels closer to Chrome than to a novelty AI wrapper — tabs, extensions, and bookmarks behave the way you'd expect — and the AI layer sits in a sidebar you can ignore entirely if you just want a normal browser that day. Here's what setup actually involves, what each pricing tier gets you, and where I'd slow down before trusting the Agent with anything that touches a real account.
What you'll need
Tabbit AI runs on macOS 12.0 or later (Apple Silicon only — Intel Macs aren't supported) or Windows 10/11; mobile versions were still in testing as of this writing. You don't need an invite code — the download is open, and sign-in takes an email or an existing Google/Apple account. If you want to migrate history, bookmarks, and saved passwords from your current browser, keep it installed during setup so Tabbit can read its profile directly; the import is one click but it needs the source browser present on the machine. No credit card is required for the Free or Standard tiers — you'll only be asked for payment if you choose to upgrade to Pro.
Step-by-step: Setting up Tabbit AI
1. Download and install
Grab the installer from tabbit.ai for your OS. Installation is a standard drag-to-Applications on Mac or a normal Windows installer — nothing AI-specific about this step.
2. Migrate your existing browser
On first launch, Tabbit offers to import bookmarks, history, and saved logins from Chrome, Safari, or Edge. I migrated a Chrome profile with a few hundred bookmarks and it carried over folders and favicons correctly, including open tab groups.
3. Open the AI sidebar and pick a model
Click the sidebar icon to open Tabbit's chat panel, then use the model picker to choose which AI you want to talk to. Free and Standard tiers rotate through the latest models Tabbit has integrated; Pro adds guaranteed access to top-tier options like GPT-5.6-Sol, Claude-Opus-4.8, and Gemini-3.6-flash.
4. Chat with the page you're on
With any webpage open, ask the sidebar a question about it directly — "summarize this," "pull the pricing table into a list" — and Tabbit reads the page content into context automatically, without you copying and pasting anything.
5. Run a task with Agent Mode
Switch the sidebar to Agent Mode and give it a multi-step instruction — research a topic across several sites, fill out a form, or pull data from a set of tabs into a summary. The Agent opens tabs, reads content, and acts on your behalf while showing its steps as it goes, so you can stop it if it heads the wrong direction.
6. Save a Trick for repeat tasks
If you find yourself giving the Agent the same kind of instruction often, save it as a "Trick" — Tabbit's term for a reusable prompt or script tied to a shortcut, so you don't retype the same brief every time.
7. Choose a plan
Free works out of the box with a weekly usage allowance. Setting Tabbit as your default browser unlocks Standard for free, at 10x the usage. If you're running the Agent daily or want guaranteed access to frontier models, Pro is a $30/month upgrade from inside the app.
Example prompts you can copy
Tabbit's sidebar and Agent respond to the same kind of specific, scoped instructions that work in any chat-based AI tool. A few I reused across sessions:
- "Summarize this page in 3 bullet points, then tell me what's missing compared to the top 2 search results for the same topic."
- "Open these 5 product pages in new tabs, pull the price and shipping time from each, and put it in a table."
- "Fill out this contact form with my saved info, but leave the message field blank so I can write it myself."
- "Compare this article's claims against the source it links to and flag anything that doesn't match."
- "Save this as a Trick: whenever I ask, summarize the current tab's comments section and rank the top 3 counterarguments."
Naming the output format — a table, a bullet list, a specific number of items — cuts down on re-prompting more than anything else.
Common mistakes to avoid
The mistake I made first: letting the Agent loose on a task with a vague brief and assuming it would ask clarifying questions the way a chat model does — it mostly doesn't, it just starts opening tabs and acting on its best guess, so a fuzzy instruction produces a fuzzy result you have to redo. Second, treating Standard's "free" unlock as permanent without realizing it requires Tabbit to stay your default browser — switch that setting back and the usage cap drops with it. Third, running Agent Mode against a page that requires login (email, banking, a paid subscription) without watching it closely; the Agent can fill forms and click through multi-step flows, and that's exactly the kind of task where a wrong click has real consequences. Fourth, assuming every model in the picker behaves identically — in my testing, output length and tone varied noticeably switching from a Chinese-market model like Doubao to GPT, so re-check tone-sensitive output after a model switch. Fifth, skipping the browser migration step and starting from a blank profile, which throws away the actual point of an AI-native browser replacing your daily one instead of sitting alongside it.
Tabbit AI pricing
Tabbit's pricing is tier-based rather than pay-per-use, and the free tiers are genuinely usable, not a locked demo. I confirmed the numbers below directly on Tabbit's membership page.
| Plan | Price | Usage | What it includes |
|---|---|---|---|
| Free | $0 | 1x (baseline) | Latest rotating models, unlimited default-model chats, docs/image/research tasks, vertical tabs, data sync |
| Standard | $0 (set Tabbit as default browser) | 10x Free | Priority service, multi-model chat, everyday Agent use, 1 scheduled task |
| Pro | $30/month | 100x Free | Priority stability, top-tier models (GPT-5.6-Sol, Claude-Opus-4.8, Gemini-3.6-flash), 10 scheduled tasks, full Agent capabilities, multi-device sync |
Tabbit AI vs. Dia Browser at a glance
Dia, from The Browser Company, is the closest comparison point — another AI-native browser built around a chat sidebar and page context rather than a plugin bolted onto Chrome.
| Tabbit AI | Dia Browser | |
|---|---|---|
| Free tier | Yes — chat, Agent, docs/image tasks | Browsing only, no AI features |
| Entry AI price | $0 (Standard, default-browser unlock) | $20/month (Better Answers) |
| Top tier price | $30/month (Pro) | $100/month (Better Days) |
| Platforms | macOS 12+ (Apple Silicon), Windows 10/11 | macOS 14+ (Apple Silicon) only |
| Model choice | 10+ models, user-switchable | Underlying models not user-selectable |
| Agent/automation | Agent Mode + scheduled tasks (Standard/Pro) | Skills + Reports (Better Days tier only) |
Tabbit's free tiers cover more ground before you pay anything, and it runs on Windows, which Dia still doesn't. Dia's paid tiers integrate directly with tools like Slack, Notion, and Gmail in a way I didn't find an equivalent for in Tabbit.
Tools that make this easier
If Agent Mode is the part you're actually here for, it's worth comparing against ChatGPT’s own Agent Mode to see whether a browser-native agent or a standalone one fits your workflow better — they solve overlapping problems differently. For research specifically, ChatGPT’s search engine mode is a lighter-weight alternative if you don't need multi-tab automation. Since Tabbit lets you switch models mid-task, my Claude vs. ChatGPT comparison is a useful reference for which model to pick for which kind of prompt. If you're using Tabbit for content work rather than research, best AI tool for content creation and best AI writing tools cover dedicated options worth pairing it with. And if you're curious about the technical side of running models inside a browser at all, WebLLM covers a different, fully local approach to the same idea.
My take
Tabbit's actual differentiator isn't any single feature — it's that the AI layer sits inside a browser that otherwise behaves like Chrome, migrates your existing setup cleanly, and doesn't force you into one AI vendor. The free and Standard tiers are enough to figure out if the Agent fits your workflow before you'd ever consider Pro's $30/month. What I'd want more history on before trusting it with anything sensitive is exactly what a same-market comparison like Dia can't tell you: how Tabbit's Agent handles logged-in flows and payment forms at scale, since that's the riskiest thing an agentic browser is asked to do. For research, tab management, and low-stakes automation, it earned a spot in my regular rotation. For anything touching a real account, I still watch every step.
Frequently Asked Questions
Is Tabbit AI free?
Yes, in a real way. The Free tier needs no card and no default-browser change. Standard, also free, unlocks 10x the usage once you set Tabbit as your default browser. Only Pro, at $30/month, costs money, and it's optional — for top-tier models and heavier Agent use.
How long does it take to set up Tabbit AI?
Installing and migrating your browser data takes a few minutes. Learning which tasks the Agent handles well versus which need a tighter brief takes a session or two of real use, the same as with any agentic AI tool.
What is the easiest way to get good results from Tabbit AI?
Give the Agent a scoped instruction with a clear output format — "pull these 5 prices into a table" beats "help me shop" — the same rule that makes any chat-based AI tool more useful.
Does Tabbit AI work on Mac?
Yes, but only on Apple Silicon Macs running macOS 12.0 or later — Intel Macs aren't supported. Windows 10/11 is fully supported, and mobile versions were still in testing as of this writing.
How is Tabbit AI different from Dia Browser?
Tabbit gives you AI chat and Agent automation for free, plus a $30/month Pro tier and Windows support. Dia requires $20/month just to unlock AI features at all, its top $100/month tier adds Reports and a daily briefing, and it currently runs on Apple Silicon Macs only.
