69 free marketing tools and 44 guides for founders, grouped by the job you are trying to do: find the right subreddits, write the post, keep your account safe, and measure what happened. Every tool runs in the browser with no signup.
Not sure where to start? The table below maps 10 common situations to the right tool, and the 4-step starter flow takes you from zero to a first post that survives the mods.
Decision helper
Find your situation in the left column. Start with the first tool, use the second if the first one answers only half the question.
| Your situation | Start here | What you get |
|---|---|---|
| I don't know which subreddits to post in | Shortlist 3-5 communities, then compare them side by side. | |
| I have a subreddit in mind but I'm not sure it fits | Check activity, rules and self-promo tolerance before you write. | |
| My account is new or low on karma | See the thresholds you need to clear, and how long it takes. | |
| I need a first draft | Generate, then score and rewrite the title. | |
| I have a draft and I'm afraid it gets removed | Get a rule-by-rule verdict and an AutoMod removal estimate. | |
| My draft sounds like ChatGPT wrote it | Fix the flagged phrases, then read it out loud once. | |
| My posts get zero views or comments | Rule out a shadowban or a low trust score before you change the content. | |
| I want threads to reply to, not posts to write | Find live threads, draft a reply, rewrite it in your voice. | |
| I posted and want to know if it worked | Compare your numbers against subreddit-size benchmarks. | |
| I'm not sure Reddit is the right channel at all | Pick one channel first, then come back for the tools. |

REDDIT MARKETING TOOL PRICING
They are asking for a product like yours on Reddit right now. The only question is whether they find you or your competitor.
Founders already growing with MediaFast
EVERYTHING IN MONTHLY, PLUS
If we can't help you market on Reddit, we'll refund you. No questions asked.
Costs, accounts, AI output and where to start.
Yes. Every tool on this page is free to use with no signup required. AI-powered tools are rate-limited per visitor to prevent abuse, so if you hit the limit, wait a minute and try again. MediaFast's paid plan is separate: it runs subreddit discovery, rule checks, drafting and scheduling for you every week.
If Reddit is new to you, start with Find My Subreddits to shortlist communities, then Subreddit Posting Requirements to see whether your account qualifies, then the Reddit Post Generator for a first draft, and finally the Subreddit Rules Checker before you post. The 'which tool do I need' table on this page maps 10 common situations to the right starting tool.
They are built for founders marketing on Reddit and LinkedIn, not generic content writing. The Reddit tools are organized around the problems that sink most posts: wrong subreddit, account below the posting threshold, rule violations, and drafts that read as ads or AI. Several tools read live public Reddit data, like subreddit rules, account age and karma.
No account is required for any free tool. Open the page and start. Tools that check a Reddit account only need a public username, never your Reddit password.
You provide inputs like your topic, tone, product URL or target subreddit. The tool sends them to a large language model with instructions written around Reddit and LinkedIn norms, and returns a draft, score or list in seconds. Treat every AI output as a first draft: add your own experience and numbers before you publish.
The tools themselves do not post anything or touch your account, so using them carries no risk. What gets accounts banned is how you post: the same link across many subreddits, heavy self-promotion, or ignoring a community's rules. The tools in the 'stay unbanned' group exist to catch those problems before you post.
The free tools each do one job, one time, when you run them. MediaFast connects the jobs: it finds subreddits that fit your product, checks their rules, drafts posts you edit and approve, schedules them, and flags threads worth replying to. You still write your comments yourself.
