29 free tools
Free tools for demand and competitor intelligence
29 free tools across 6 jobs: getting recommended by AI assistants, the on-page and technical work that decides whether a page can be read at all, finding people who are actively asking to buy, tracking competitors, and the Reddit specifics. Every one has a complete core that is free with no account and no card. 8 never leave your browser.
Technical SEO & Structured Data
Free tools for the machine-readable layer: robots.txt, JSON-LD, Open Graph, and whether a page can be indexed at all. Each one reads its own output back through a real parser, so what you are told is what a crawler will actually see.
Structured data
Open Graph Checker
Reads your og:image file and reports its real dimensions, rather than trusting the width you declared in a meta tag.

Build JSON-LD for ten schema types with a hint on every field, then check it against the markup already on your page.
Try it free ->Technical SEO
Robots.txt Generator
Build a valid robots.txt from a preset or your own rules, then see the file read back through a real parser before you ship it.
Try it free ->On-Page SEO & Content
Free tools for the on-page work that decides whether a page can rank at all: headings, titles, descriptions, readability and keyword coverage. Every check shows the threshold behind it, so the result is something you can argue with rather than a score you have to trust.

Try it free ->Why these tools are free
Every tool here does, by hand, one job that Linkeddit automates. You can generate a set of competitor complaint searches in a minute and get real switching-intent threads without paying anyone. You can build a battlecard, model the ROI of a competitive intelligence program, or ship a valid llms.txt file today.
What the free versions cannot do is run without you. They do not remember what you found last week, dedupe repeat signals, grade which competitor move actually matters, or put a brief in your inbox every Monday.
That gap is the product. Compete delivers a graded weekly brief on every competitor you track. Demand Intelligence runs intent searches continuously and scores each result. Answer Radar measures your share of AI recommendations over time.
So the tools on this page are not crippled samples with a paywall halfway through. They are the honest manual version, and they stay free.
FAQ
Free tools, answered directly
The questions people actually ask before using a free tool from a paid product.
Are these tools really free?
Yes, and specifically: every one of the 29 tools here has a complete core you can use for free, with no credit card and no trial. 8 run entirely in your browser and never send anything to us at all. 14 of them additionally carry a deeper layer behind a free sign-in, and three of those spend real money per run and are limited to one run a month. The free core is never a crippled sample of the paid thing: the sign-in adds a layer, it does not take a piece out of the result.
Do I need to create an account?
Not to get a result. Every tool here answers your question without an account, and 8 of the 29 never leave your browser. 14 have an extra layer that does need a free sign-in, and it is genuinely extra: the deeper read of your own page, or a comparison against a second one. Three of those cost us money per run, so they are metered at one run per account per month. Tools that fetch a live URL are also rate limited per visitor, to keep them available rather than to push you anywhere.
What is the catch?
These tools do the manual version of jobs Linkeddit automates. Generating a set of competitor complaint searches takes a minute; running those searches every week, deduping the results, and grading which ones signal a switchable account is what the paid product does. The free tools are genuinely complete for one-off use.
Which free tool should I start with?
If you sell software and want to know why buyers are not finding you, start with the AI Visibility Checker and the llms.txt Generator. If you want pipeline this week, start with the Buyer Intent Query Builder or the Competitor Complaint Finder. If you are preparing a sales team, start with the Battlecard Generator.
Do the tools that fetch live data use real sources?
Yes. The Subreddit Finder and Best Time to Post tool read Reddit's public data directly, and the AI Visibility Checker queries a real answer engine and quotes the response it received. Nothing on this page returns invented metrics, estimated volumes, or fabricated answers.
Can I use these tools for client work?
Yes. Agencies and consultants use them for pitch prep, competitive audits, and onboarding research. There is no license restriction on the output. If you are running the same audit across many clients every month, the paid product will be faster than repeating the manual loop.
