AI画像生成が「誰でも使える」時代に

2025年はAI画像生成技術が本当に大衆化した年でした。MidjourneyからDALL-E、Stable DiffusionからFluxまで、様々なAIモデルが登場しました。しかし一般人にとって、ある厄介な現実が続いています:

「AIで素敵な画像を生成したいけど、プロンプトの書き方がわからない。」

2026年のAI画像生成ツールの3つのタイプ

詳しく見る前に、市場にある3種類の主要なAI画像ツールを理解しましょう:

🎨 Lovart - Professional Designer Canvas

Lovart Canvas Interface - Professional design workflow with canvas, layers, and collaboration features

Raphael - Minimalist Simple Interface

Raphael Simple Interface - Basic text input with auto model routing

CreateVision AI - Smart Companion with AI Agent

CreateVision AI Interface - AI Agent auto-recommendation with smart model selection

🎨プロフェッショナルデザイナーツール(Lovartを例に)

Features:

  • Complete "ChatCanvas" design workflow
  • Support for image, video, 3D and other formats
  • Annotation, marking, and sketching on canvas for team collaboration
  • Multi-model access and unlimited project creation

✅ Advantage: 機能が充実し、専門性が高く、デザイナーが完全なワークフローを構築するのに適しています

⚠️ Problem: 一般人にとって、キャンバス機能は理解コストを増やします。単に素敵な画像を生成したいだけなのに、キャンバスの使い方を学び、レイヤーの概念を理解し、コラボレーション注釈をマスターする必要があります—個人ユーザーには全く意味がありません。

👥 Best for: プロのデザイナー、デザインチーム、エージェンシー

シンプル初心者ツール(Raphaelを例に)

Features:

  • Completely free, no registration required
  • Smart model routing, automatic model selection
  • Create images directly from text descriptions
  • Privacy-first, no data storage

✅ Advantage: ゼロバリア、ゼロコスト、すぐに使える

⚠️ Problems:
  • Limited functionality: Lacks scene guidance. When facing a blank input box, you still don't know what to write—"a dog" works, but "help me generate a nice food photo for social media" is impossible
  • Limited quality: Uses basic models, output quality differs significantly from professional tools—blurry details, flat lighting, simple composition
  • Missing scenarios: Professional needs (ID photos, product shots, wedding photos) cannot be addressed

👥 Best for: AI画像生成を試してみたい好奇心旺盛なユーザー、品質要求の低い一時的なニーズ

スマートコンパニオンツール(CreateVision AIを例に)

Features:

  • Three usage modes covering beginners to advanced users
  • AI Image Tools: True 0-prompt experience
  • 12 scene templates: Cover 90% of life's image needs
  • AI Mentor system: Professional prompts at your fingertips
  • AI Agent: Automatically selects optimal model and optimizes prompts

✅ Advantage: 複雑さはあなたが決めます。素早く画像を生成したい場合も、細かく調整したい場合も、対応できます。プロ級のAIモデルを使用して出力品質を保証します。

👥 Best for: 一般人、コンテンツクリエイター、画像処理が必要だが専門スキルを学びたくないユーザー

vs Lovart:キャンバスが一般人に必要ない理由

Lovart's "ChatCanvas" design canvas feature is great for professional designers—you can annotate, mark, and sketch on a unified canvas, with AI responding to design in a conversational way. But the problem is: You just want to generate a nice image, you don't need the "canvas" concept. Collaborative annotations have no value for individual users. Multi-format output adds complexity. Prices from $10 to $60/month are too expensive for regular needs.

Lovartは簡単な編集にPhotoshopを使うようなものです—大げさすぎます。ツールを半日学んでも、機能の1%しか使いません。

vs Raphael:「無料でシンプル」では不十分な理由

  • Blank input box dilemma: When facing a blank input box, you still don't know what to write
  • Quality limitations: Uses basic models, output quality differs significantly from professional tools—blurry details, flat lighting, simple composition
  • Missing scenarios: No scene guidance or template support, true beginners are equally lost
  • Professional gap: Want ID photos? Product shots? Wedding photos? Sorry, Raphael can't handle that

Raphaelは「AIで画像が生成できるか試してみる」好奇心を満たすには適していますが、日常のツールにはなれません。

CreateVision AI Difference

🎛️

Core Philosophy: You Decide the Complexity

Can be as quick as Raphael (use AI Image Tools), or as refined as advanced users (use AI Mentor + manual mode), or let AI decide (use AI Agent auto-recommend)

🎯

Scene-Driven, Not Tool-Driven

Instead of giving you a blank box for free expression, we first ask: "What do you want to do?" Then provide the most suitable tools and presets based on your answer.

🤝

True AI Companionship

Not a cold tool, but "your friend who's best at photo editing" helping solve problems. Don't know? Use templates. Want to learn? Use mentors. Want speed? Use Agent.
