Choosing an AI tool for content creation often means deciding between two types of platforms: one that helps build a content strategy and another that polishes the final text. Scalenut and Grammarly are examples of these different approaches.
Scalenut is an end-to-end platform for planning, researching, and creating content optimized for what it calls Generative Engine Optimization (GEO). This targets both traditional search engines and AI answer engines. Grammarly is a writing assistant that focuses on making sure text is clear, correct, and professional. While their main functions are different, their use of generative AI can create some overlap for users trying to find the best tool.
This guide provides a factual comparison of Scalenut and Grammarly by looking at their features, pricing, and typical use cases based on their official documentation. We will also introduce an alternative, the eesel AI blog writer, for teams that want to generate complete, publish-ready blog posts from just a keyword.
What is Scalenut?
Scalenut is a platform for what it calls Generative Engine Optimization (GEO). It is designed to manage the content process from start to finish, aiming for visibility on search engines, AI platforms like ChatGPT and Perplexity, and social sites like Reddit. The goal is to help businesses get discovered by creating and optimizing content for these different channels.
The platform is based on four main components:
- GEO Core: This is the main toolset for planning, creating, optimizing, and auditing content. It includes features like the Cruise Mode article writer, which generates a draft from a keyword, a content optimizer with a GEO Score to guide improvements, and a keyword planner for building topic clusters.
- GEO Watchtower: This tool tracks a brand's visibility and mentions in AI-generated answers on platforms like ChatGPT, Claude, and Google’s AI Overviews. It helps teams see how their content is being used by generative AI.
- Social UpReach: This tool monitors keyword mentions and conversations on Reddit. The information can be used to inform content strategy by finding new trends and user questions directly from community discussions.
- Backlinks Marketplace: This is a platform where users can buy backlinks from publishers to build domain authority, supporting off-page SEO efforts within the Scalenut system.
Scalenut is intended for SEO specialists, content marketing teams, and digital agencies that need a structured process to produce content for multi-engine visibility.
What is Grammarly?
Grammarly is an AI writing assistant that helps users improve their writing. Its main purpose is to find and fix errors in grammar, spelling, punctuation, and style. Beyond basic proofreading, Grammarly offers suggestions to improve clarity, tone, and readability across different platforms like email clients and web browsers.
Key features include:
- Advanced corrections: It finds complex grammatical errors and suggests ways to improve sentence structure and word choice to make writing more direct.
- AI agents: Grammarly has specialized tools like Proofreader for final checks, Paraphraser for rewording sentences, and Humanizer to help make AI-assisted writing sound more natural.
- Plagiarism checker: This feature compares text against billions of web pages and academic databases to check for originality, which is useful for academic and professional writing.
- Go AI assistant: A generative AI feature that helps write, rewrite, and brainstorm text inside different applications. It can generate outlines, draft emails, or create paragraphs from a user's prompt.
- Security and compliance: Grammarly has several enterprise-level security certifications, including SOC 2 (Type 2) and multiple ISO certifications like ISO/IEC 27001, showing its focus on data security.
Grammarly is made for a wide audience, including students, professionals, writers, and business teams who need to make sure their writing is error-free and effective.
Feature comparison: Scalenut vs Grammarly
Although both tools use AI, their features apply to different parts of the content process. Scalenut is for strategy, research, and drafting content meant for various search engines. Grammarly is for refining the final text to improve its quality and clarity.
| Feature | Scalenut | Grammarly |
|---|---|---|
| Primary Goal | Generative Engine Optimization (GEO) and content creation | Writing correctness, clarity, and tone |
| Core Audience | SEO managers and content marketers | All writers and professional teams |
| Content Generation | Cruise Mode for full articles | Go AI assistant for in-line assistance and text generation |
| SEO/GEO Tools | Comprehensive (GEO Core, Watchtower, Social UpReach) | None |
| Proofreading | Basic grammar and spell check | Advanced suggestions for grammar, style, tone, and clarity |
| Plagiarism Checker | Yes (via integration) | Yes (built-in, checks billions of pages and academic databases) |
| Security | Standard security practices | Enterprise-grade (SOC 2 Type 2, multiple ISO certifications) |
Content strategy and optimization
This is Scalenut's main strength. The platform is centered on GEO, which goes beyond traditional SEO to include visibility in AI answer engines.
- GEO Core offers tools for keyword clustering, creating content briefs, and auditing performance.
- GEO Watchtower lets users track brand visibility in AI engines like ChatGPT and Claude, providing information on where their content is sourced for AI answers.
- Social UpReach follows Reddit conversations to find content ideas and analyze sentiment.
Grammarly has no direct SEO or GEO features. While making content more readable can indirectly help SEO by improving the user experience, it doesn't have the strategic tools for a data-driven content plan.
AI content generation
Scalenut’s Cruise Mode is built to generate a full-length, SEO-optimized blog post from a keyword in a five-step process. It automates research by looking at top-ranking content and structures the article with headings and key points to produce a first draft.
Grammarly's generative AI, available through its Go assistant, acts more like a writing partner. It can generate text for articles, emails, and outlines from a prompt, but it's mainly designed to help within an existing writing task, not to produce a complete article in one go. Its strength is in enhancing the writing process.
Writing assistance and proofreading
Grammarly is the leader in this area. Its AI provides context-aware suggestions for grammar, punctuation, style, and tone. It can change its feedback based on the user's intended audience and goals. The platform also has AI agents like the Paraphraser for rewording text and the Humanizer for making AI-generated writing sound more natural.
Scalenut's GEO Core has basic proofreading and an "AI Detector & Humanizer" as a paid add-on. Its focus is on content structure and keyword optimization, not detailed linguistic improvements. It checks for basic errors but doesn't offer the deep stylistic feedback that Grammarly does.
Pricing comparison for Scalenut vs Grammarly
The pricing for Scalenut and Grammarly is based on their different product offerings and target users.
Scalenut pricing
Scalenut uses a modular pricing model based on its four components. The main product, GEO Core, has several tiers with different usage limits.
- Essential: Starts at $49 per month for 5 articles and 5 pages to optimize.
- Growth: Starts at $79 per month for 30 articles and 30 keyword clusters.
- Pro: Starts at $149 per month for 75 articles and additional team members.
Other components like GEO Watchtower, Social UpReach, and add-ons have separate pricing. For instance, Social UpReach starts at $19 per month. This approach lets users create a plan for their specific needs but can also raise the overall cost.
Grammarly pricing
Grammarly has a useful free version, with paid plans that add advanced features for individuals and teams.
- Free: $0. Offers basic grammar, spelling, and punctuation checks, plus limited use of generative AI.
- Pro: Starts at $12 per member per month (billed annually) or $30 per month billed monthly. It provides full-sentence rewrites, tone suggestions, plagiarism detection, and more generative AI features.
- Enterprise: Custom pricing. This plan includes advanced security features like SAML single sign-on, a style guide, and specific team features.
