First of all, RIP Arc.
Secondly, just used Tabbit CLI to scan 400 replies to Arc's sunset post. Here are the features people want to keep. Which would you miss most and what would you like Tabbit to build next?
🤖 Made with AI
We've decided to sunset Arc on December 22, 2026.
That's not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community.
Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that's where our engineering and security teams will focus moving forward.
We've worked to make switching to @diabrowser as easy as possible for Arc members. Here's how:
· Your passwords, bookmarks, extensions and history come over to Dia seamlessly.
· Spaces, Folders, and Tab Groups are in Dia and import over with your data intact.
· Dia now surpasses Arc benchmarks in stability, speed, and security.
· The browser features you use in Arc are free in Dia, and the AI is optional.
Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We'd love for you to be there with us when it lands.
Markdown is becoming the default file format for humans and agents working together in the AI era.
Tabbit gives you browser automation and Markdown preview in one place, and right now it's the best combination.
折腾了大半天markdown软件最后发现，居然最适合自己的是一款浏览器，而且让 Claude 配合浏览器的技能做视频的上传发布和抓数据，特别省token，而且效率很高，感谢美团出品。
Tabbit - The browser for the AI era @TabbitBrowser 已经成为的默认浏览器了，Chrome都很少打开
Tabbit v1.17: always on the way to elevating your daily experience.
Skills Market now lets you browse by content category. Find Skills for content creation, productivity, study, and more.
Btw, screenshots in Tabbit now support scrolling capture on macOS. A better way to share great tea with your friends 👀
Tabbit v1.16 is live.
Preview, translate, and export your files without leaving the browser.
One place to manage your Markdown, HTML and PDFs.
Claude Haiku 5.5 is now available in Tabbit.
It’s Anthropic’s fastest model yet, which makes it a good fit for the little questions that come up while browsing: what a paragraph means, which details matter, or how to phrase a reply.
Pick Haiku-5.5 from the model menu and ask about the page you’re on.
We gave Claude Sonnet 5.5 its own developer guide and asked it to turn the article into an interactive model picker and migration checklist inside Tabbit.
Finished in under 30 seconds, using just 0.38% of the available token budget.
Claude Sonnet 5.5 is now live in Tabbit.
OpenAI and Anthropic released three new models within hours of each other. We spent the last few hours getting all three into Tabbit.
GPT-6 Sol, GPT-6 Luna, and Claude Opus 5.5 are live now.
Use them with the page you’re already on, and switch models whenever the task changes.
uBlock Origin has long been considered the gold standard for blocking ads and trackers. But on Chrome, the original version has become increasingly difficult to use.
Tabbit now includes the original uBlock Origin, built directly into the browser.
It’s off by default. To turn it on, go to:
Settings → Extensions → My Extensions → Built-in Extensions
AI browsers don’t need more features. They need less friction.
In Tabbit 1.14, you can search long conversations instead of scrolling, type @ to find your latest tabs first, capture context directly from chat or the toolbar, and choose what syncs across devices.
Small changes, but together they make the browser feel much more in step with how you work.
Tabbit 1.14 is live.
Keep building.
Give your agents a faster, better way to get real work done in the browser.
Love,
Tabbit CLI
使用了十几款 AI 浏览器后，兜兜转转又用回了美团的 @TabbitBrowser。
不得不说，在场景工程化落地这件事上，国内团队的执行力确实很强。曾经被寄予厚望的 ChatGPT Atlas 已经死了，Dia 和 Chrome 的 AI 功能还在挤牙膏，反倒是 Tabbit 把实用性和产品纵深打磨出来了。
说实话，Tabbit 刚上线时我还锤过它：当时发现它的翻译功能抄袭陪读蛙，我顺手把截图转给作者，后来还在科技媒体圈引发了一波热议。本以为又是一款昙花一现的套壳产品，但后续的高强度迭代确实颠覆了我的预期。
促使我重新把它作为主力工作台的几个硬核特性：
- 双模架构与模型调度：Chat 与 Agent 模式并存，做深度行业调研效率极高。虽然免费版只能用一些轻量模型，但额度够用；DeepSeek v4.1 Flash 的响应速度飞快，国际版还支持 Gemini 3.8 和 GPT-5.6 Luna。
- 开放外部 Agent 操控：这是我重新回坑的关键契机。它开放了底层控制能力，在 Claude Code 等外部 Agent 工具中输入 /tabbit ，直接挂载并驱动 Tabbit 接管真实浏览器操作，这直接让最近很火的 Ego Lite 黯然失色。
- 标签管理与无缝迁移：智能分组与缩略图预览把杂乱的多标签状态收拾得非常清晰；同时支持从 Chrome、Arc、Edge 一键无损迁移历史记录、Cookie、扩展，无缝上手，也有同步功能。
- 告别吃灰的“活”收藏夹：它的收藏夹不是用来存死链接的，而是让你能直接把网页里的高亮段落、连同你和 AI 讨论出来的核心结论一起存下来，并由 AI 自动生成重点摘要。

DeepSeek-V4.1-Flash is now live in Tabbit. ⚡
Fast, efficient, and natively multimodal, it can understand both the text and images on the page you’re viewing.
Summarize a long read, compare sources, extract the important bits, or start writing, all with the page already in context.
Once Codex can control the Tabbit browser, you can give it access to your browser, inherit your existing login sessions, and get work done.
- Search Amazon for newly launched products and maintain the results in Google Sheets
- Export operational data from the Shopify admin and analyze it
- Have it browse your Twitter feed and summarize the posts
...
And it’s not limited to Codex. Other agents, including Claude Code, Grok , Antigravity, and OpenCode, can use it as well.
Try the same setup with Codex:
- Install the latest Tabbit
- Connect Codex to Tabbit
- Type /tabbit, then describe the browser task
- Start simple: ask Codex to review a site where you are already signed in and collect what is worth reading today.
