Copy.ai – Surprisingly Useful

Copy.ai is made with marketers in mind but works well for writers who need punchy, energetic copy. It excels at creating bold openings and fleshing out arguments.

Its tone customization lets you choose styles from formal to casual, while the talking points feature breaks down big ideas into manageable chunks for quick outlines. The auto paragraph expansion turns short input into fuller explanations.

Copy.ai is ideal for confident, convincing text such as persuasive writing, opinion pieces, or meeting prep. It also works well as a brainstorming tool.

Copy.ai’s strengths:

• Tone customization from formal to casual
• Breaking down ideas into talking points

Extra tip: Pair Copy.ai with a reference manager like Zotero to add context and credibility to your paragraphs.

AI-Writer – The Source-Finder

AI-Writer generates drafts based on existing sources, automatically citing them in recognized styles. It minimizes non-contextual content, focusing on research-based writing.

The fast draft mode produces structured, fact-packed drafts in under 10 minutes. It also offers a “reword” tool, giving three alternatives if a sentence feels out of place.

Keep in mind, AI-Writer’s output can sound formal and mechanical, which works well for technical writing but may need tweaking for a more personal voice.

AI-Writer’s strengths:

• Automatic citation generation in real-time
• Research-focused content with minimal fluff
• Quick draft creation

Simplified – Strong on Design

Simplified offers one of the cleanest interfaces and works well for both creative and academic writing. It supports long-form drafts with multiple sections and provides visual organisation using sidebars, cards, and content blocks.

The tone sliders let you adjust style from casual to academic instantly. It’s great for digital media, PR, marketing texts, and brainstorming visuals alongside writing—for example, presentations.

Simplified includes a built-in plagiarism checker, which is not as detailed as StudyPro’s but useful for quick scans. Its attractive interface and flexibility strike a good balance for many users.

Simplified’s strengths:

• Long-form assistant for multi-section drafts
• Visual organisation tools
• Tone sliders for real-time style adjustment
• Quick plagiarism checking

Buffer AI Tools – Great for Small Tasks

Buffer AI tools are best suited for short-form tasks like discussion posts or reflection paragraphs. It’s not ideal for full documents but shines when you need to polish or expand small sections quickly.

Its sentence expansion tool turns brief notes or bullet points into complete thoughts. The tone adjuster can make writing sound more formal without changing the message. Rewrite suggestions tighten up repetitive or vague parts.

Buffer runs in-browser, responds quickly, and doesn’t require a full account to start.

What works well:

• Sentence expansion from notes
• Tone adjustment for formality
• Rewrite suggestions to improve clarity
