今日のAIブラウザアシスタントの位置づけ
Most results are chat layers. Tabbit targets Tier 3–4: research plus execution in one free browser.
Comet (Perplexity)
Tier 2–3Strength: Personal assistant branding, task automation pitch
Gap: Limited public detail on multi-tab @ context and parallel execution
Brave Leo
Tier 1Strength: Privacy-first in-page Q&A
Gap: No Agent lane or multi-tab research workspace
Gemini in Chrome
Tier 2Strength: Page gist, compare, light Auto Browse
Gap: Chrome-only, Google account, weak cross-tab grounding
HARPA & extensions
Tier 1–2Strength: Summaries on any site you visit
Gap: Extension friction, API keys, brittle automation
Tabbit — Tier 1–4 in one free AI-native browser
A day with Tabbit
一日を通じたAIブラウザアシスタント
Three moments where a built-in assistant beats another extension.
Morning brief from open tabs
@ your news and inbox tabs—Omnibox summarizes priorities before your first meeting.
Research sprint in parallel
Agent reads a tab group, drafts a cited memo. You stay on the slide deck in your main lane.
Execute repetitive flows
Agent fills forms and aggregates vendor quotes—Skills (/ shortcuts) reuse the workflow tomorrow.
Assistant vs extension
Tabbitがより完全なAIブラウザアシスタントである理由
Extensions and built-in chat solve Tier 1–2. Tabbit covers the full ladder.
| 機能 | 一般的なアシスタント | Tabbit Tabbit |
|---|---|---|
| Multi-tab @ context | Single page or none | Tabs, groups, files, screenshots |
| Executes clicks & forms | Rare / brittle | Agent Mode in background lane |
| Parallel browsing | Blocks or overlays current tab | Isolated Agent tag group |
| API keys required | Often yes (extensions) | Integrated models—free in beta |
| Vertical workspaces | N/A | Built-in tab groups + Omnibox |
| Skills / repeatable flows | Manual prompts | / shortcuts + Skills plaza |
Built in, not bolted on
What your personal assistant gets on day one
Omnibox assistant
URLs, search, and agent commands share one input—your assistant is always one keystroke away.
@ grounding
Reference any tab, group, screenshot, or local file—the assistant sees what you see.
Agent tag group
Long tasks run in isolation while you browse, email, or present in the main thread.
Free top models
International and domestic editions ship leading models at no cost during public beta.
FAQ
AI browser assistant questions
An AI browser assistant is AI embedded in the browser—not a separate chat app—so it can read pages you open, answer in context, and optionally execute tasks. Tabbit extends this with @ multi-tab grounding and Agent execution.
