AI Writing & Rewriting Tools
Free AI Writer
Drafts blog posts, ads, and emails from a single prompt. Free runs, no account required.
AI Article Writer
Generates full SEO-optimized articles from a keyword: real structure, headings, and sections instead of a blank page.
AI Article Reviewer
Reviews AI or human-written content and flags robotic tone, flat phrasing, or weak flow before it goes live.
AI Paraphrasing Tool
Rewrites a passage completely into a new version while keeping the meaning intact.
Free AI Rewording Tool
Edits only the clunky parts of a sentence for clarity, rather than rewriting the whole thing.
AI Detection & Humanizing Tools
AI Text Humanizer
Strips the AI tells from machine-drafted text so it reads like a person wrote it.
AI Content Detector
Shows you a score, not a verdict. Detectors vary in accuracy and sometimes flag human writing, so treat the result as one signal among several.
Research & On-Page SEO Tools
Competitor Analysis Tool
Uncovers a competitor's organic keywords, backlinks, and traffic sources, and shows exactly where you can outrank them.
Alt Text Generator
Writes descriptive alt text for any image in seconds. It matters more than most teams think: WebAIM's February 2026 crawl of one million home pages found 53.1% of them missing image alt text.
Why These Tools Are Free
Here's the fun part: this whole free tier is basically our marketing budget. A 2026 survey of 200 B2B software products found 3–5% of freemium users usually convert to paid, 6–8% if you're an AI product, and 15–20% means you're basically printing money. Some of you will upgrade. Everyone else just keeps the free tools, on us.

Free Tools or the Full Agent? How to Choose
Free tools
Do one task at a time: humanize a paragraph, score a draft, write alt text. Fixed limits, one job, done. That covers a lot of days.
The full platform
Covers the rest. An agent is a program that makes a decision: it works across services, reading from one and writing to another. The full SEO Suite runs 15 tools across three phases: 7 for Discovery & Research, 3 for Strategy & Planning, and 5 for Implementation. It draws on 150+ LLM models (315 in the catalog) across dozens of integrations. Never copy and paste again.
The short version: single task today? Use a free tool above. Building a repeatable SEO workflow? That's the full platform — Starter $20 or Pro $129.

Frequently Asked Questions
Straight answers on what's free, what isn't, and where each one fits.
Yes, for single tasks. Humanizing a paragraph, checking a draft, writing alt text: a free tool handles each in seconds. Free tools stop at scale and workflow — running research across a market or chaining steps together is where the platform picks up.
No credit card, ever. An account only matters if you want to save your work or move up to the full agent platform. Everything on this page runs without one.
The catch is the business model: free tools are how you discover the platform. Per the freemium-conversion survey above, single-digit conversion to paid is considered normal for B2B software. We'd rather show you the numbers than pretend the tools are charity.
Not for research at scale. Free tools handle writing, checking, and fixing one item at a time. Competitive research across a whole market, dozens of integrations, and a full model catalog is platform territory.
Unedited, generic AI content is a risk. Reviewed, humanized, on-brand content is standard practice now — that's exactly why the free set includes a reviewer, a humanizer, and a detector.
