AI ブラウザとは？
すべての「AI ブラウザ」が同じわけではない
AI ブラウザは 2 つのグループに分かれる。AI 支援型は従来のエンジンにチャットパネルを追加。AI ネイティブ型は、ウェブを読み、推論し、行動するエージェントを中心に再構築されている。
AI 支援型
Chrome + Gemini、Edge + Copilot、Brave + Leo。アクティブなページを要約し、フォローアップに答えるサイドバー。
AI ネイティブ型
Tabbit、Atlas、Comet、Dia。ブラウザ自体がエージェント：ナビゲート、抽出、比較、ワークフロー完了を行う。
なぜ重要か
チャットボットは数回のクリックを節約。エージェントネイティブブラウザは調査、データ入力、サイト横断比較といったタスクそのものを排除する。

Tabbit はどう比較されるか
A quick breakdown of where Tabbit leads — and where each rival focuses — so you can choose based on your actual workflow.
Tabbit vs ChatGPT Atlas
Them: Atlas is unbeatable if you live inside ChatGPT and want persistent cross-app memory.
Tabbit: Tabbit goes further as a browser agent: it can navigate arbitrary sites, fill forms, extract data, and run workflows outside the OpenAI ecosystem — with multi-model freedom.
Tabbit vs Perplexity Comet
Them: Comet is the research king for cited, sourced answers and parallel information retrieval.
Tabbit: Tabbit matches deep research with agentic execution. It does not just find answers — it performs the next action, from booking to reporting.
Tabbit vs Dia Browser
Them: Dia wins on polish and a minimal, Arc-like visual experience with custom AI skills.
Tabbit: Tabbit offers comparable minimalism plus deeper automation, vertical tabs, and a multi-model skill marketplace that adapts to serious work.
Tabbit vs Chrome / Edge
Them: Chrome and Edge are familiar, free, and tightly integrated with Google or Microsoft services.
Tabbit: Tabbit is not a wrapper with a chat sidebar. It is rebuilt for agentic browsing, workspace organization, and context-aware automation that traditional browsers cannot match.
