Hands-on with QuillBot AI: Review and Guide for Writers
AI tools are becoming a staple for many writers. Some worry AI might replace their role, while others see it as a way to sharpen writing skills. Accuracy, clarity, and originality remain core goals, and any tool that helps with these is worth exploring. QuillBot AI is one such tool, offering features for creating content ranging from blog posts and emails to detailed analyses.
Below is a detailed look at QuillBot AI’s core features, pricing, how it compares to other tools like Grammarly, and its usefulness in real-world writing tasks.
Core Features of QuillBot AI
QuillBot AI provides a suite of writing aids suitable for students, researchers, and professional writers. Its features include:
- Grammar checking: Covers spelling, punctuation, mechanics, and spacing.
- Plagiarism checking: Available only in the paid versions.
- Summarization: Supports paragraph or bullet point modes with customizable summary lengths.
- Paraphrasing: Offers rewriting with different tones and styles.
- Translation: Supports multiple languages including Spanish and French.
- Citation generation: Generates citations from titles, URLs, ISBNs, and more.
- Flow: An integrated word processor with AI features like grammar checks, content analytics, writing prompts, and live web search results.
QuillBot also features an AI detector that estimates the percentage of AI-written content in a document along with a confidence level. The free detector works up to 1,200 words. While helpful, these detectors aren’t foolproof and should be supplemented with human judgment.
Pricing and Integration
QuillBot AI offers three plans:
- Free Plan: No cost or registration needed. Allows paraphrasing up to 125 words in two modes, basic grammar and spelling checks, simple summaries, and the AI detector up to 1,200 words.
- Premium Plan: Priced at $8.33/month billed annually. Offers unlimited paraphrasing in all modes, advanced grammar checks, custom summaries, unlimited AI detection, plagiarism checks, translation into 40+ languages, and synonym adjustments.
- Team Plan: Pricing depends on the number of users and includes all Premium features plus team metrics, data management dashboards, centralized billing, and personalized support.
The tool supports Chrome and Microsoft Word extensions, with availability for Safari, Edge, and macOS, making it easy to integrate into various writing workflows.
How QuillBot AI Compares to Other Writing Tools
General AI chatbots like ChatGPT or Claude provide broad capabilities but lack the focused editing tools found in writing-specific AI like QuillBot.
Other notable writing tools include:
- Jasper AI: Geared toward marketing and creative content generation.
- Hemingway: Focuses on tone and readability improvements.
- Turnitin: Specializes in plagiarism detection.
- Grammarly: Offers comprehensive grammar, tone, and style checks.
QuillBot AI vs. Grammarly: A Practical Test
Testing involved feeding an 1,853-word draft into both tools. Grammarly’s free version returned 38 spelling and grammar suggestions almost instantly. QuillBot took about 10 seconds and offered 30 suggestions. Both interfaces are user-friendly with clear suggestions and easy application.
QuillBot Premium enhances this experience by providing detailed writing statistics, readability scores, tone analysis, and AI commands to expand or rephrase content.
Experienced writers should treat these tools as assistants—not decision-makers. There are times when suggestions miss the mark or don’t fit the intended tone. It's best to review each change carefully and avoid accepting all suggestions blindly.
One downside noted was that QuillBot’s free version can feel slower compared to Grammarly, reinforcing the value proposition of upgrading to Premium.
Testing Unconventional Content
QuillBot was tested with Markdown-formatted pages and Python code snippets. It handled Markdown formatting elements like bold text well but ignored unrecognized symbols without errors. For Python code, it stripped indentation but did not flag code-specific syntax issues, confirming it’s not suited for code editing but can catch basic text errors within code files.
Is QuillBot AI Worth Using?
AI writing tools are now part of many writers’ arsenals. While AI can’t replace an author’s voice and insight, features like translation and summarization add practical value. QuillBot’s free tier offers enough functionality to evaluate its suitability before committing to a paid plan.
It competes effectively with established tools like Grammarly, especially for writers seeking a mix of paraphrasing, summarization, and grammar support in one package.
For writers interested in expanding their AI toolset and improving their craft, QuillBot AI is worth exploring.
