4.5

OpenAI's general-purpose AI assistant now powered by GPT-5.4 with 1M token context and computer-use capability for desktop automation. Supports text, voice, image, file, and code workflows in one interface. Used by 400M+ weekly active users across professional and consumer contexts.

Category:AI Assistants

Features

GPT-5.4 model with 1M token context window
Computer-use feature for desktop task automation
Codex App integration for autonomous coding agents
Voice mode with real-time conversation
DALL-E image generation built in as GPT Image
+3 more

Pros

Largest installed base means most third-party integrations and community resources
GPT-5.4 scores top-3 on most public benchmarks as of Q1 2026
Computer-use reduces need for separate automation tools for desktop workflows
Custom GPTs allow non-developers to build specialized assistants without code

Cons

Plus plan ($20/mo) imposes daily message limits on GPT-5.4; heavy users hit caps before noon
Computer-use feature is US-only and requires desktop app install as of March 2026
Context window degrades in quality above 600K tokens — 1M is theoretical max, not practical
Free tier locks users to older GPT-4o mini model, not GPT-5.4
Codex App autonomous tasks can consume credits unpredictably, reaching $50+ in a single session

4.0

Notion's native AI layer that operates across your entire workspace — pages, databases, projects, and meeting notes. Updated in 2025 with full workspace Q&A (ask questions across all your notes), automatic action item extraction from meetings, and smarter database queries using natural language. Available as an add-on to any Notion plan at $10/user/month.

Category:Productivity

Features

Workspace Q&A: ask questions across all pages, databases, and team wikis
Action item extraction from meeting notes with automatic assignee detection
AI database queries: filter, sort, and analyze data with natural language
AI writing assistant with context-awareness across the current page
Autofill database properties using AI from page content
+3 more

Pros

Workspace Q&A replaces manual search for teams with large wikis — answers come with source citations
Action item extraction from meeting transcripts saves 10-20 minutes per meeting of manual note cleanup
Database autofill allows structured data entry at writing speed — describe a project and properties populate automatically
Native integration means no data leaves Notion to a third-party service for AI processing

Cons

Costs $10/user/month on top of the Notion plan ($8-18/user/mo) — total cost is $18-28/user/mo for AI-enabled teams
Workspace Q&A quality drops when pages are poorly formatted or lack structure — garbage in, garbage out
AI writing suggestions are less capable than dedicated writing tools (Claude, ChatGPT) for complex creative work
Database queries via natural language still fail on multi-join queries and complex aggregations
Action item extraction requires clean meeting transcripts — works poorly with speaker-unattributed raw notes
