AI writes the comment", "summary": "SignalsFlow launched a free beta that scans public Reddit posts to find people whose problems match a user's product, scores each post 0–100, and uses AI to draft five comments per post that the user reviews and posts from their own account. The tool generates 3 to 7 \"theses\" from a product's site or description in under a minute, lets users add up to 50 of their own subreddits, and never signs in to Reddit, reading only public subreddit pages. SignalsFlow is free during the beta with per-user daily limits that reset at 00:00 UTC, and sign-up is via Google with no invite or card required.", "body_md": "### People with the problem, not mentions\n\nThe feed looks for the need behind a post, by meaning and by words, not for your product's name. An AI judge checks the top of it.\n\nBeta · free · Reddit, read only\n\nEvery day people post about problems your product solves. Most have never heard of it. SignalsFlow finds their posts, and its AI writes a reply that answers each one and suggests your product. You check it and post it yourself.\n\nFree during the beta · Sign up with Google · No invite, no card\n\nThe problem\n\nPeople describe their problem in their own words, not in yours. An alert on your product's name finds mentions, not the people it would help.\n\nChecking a dozen subreddits by hand eats an hour a day, and the good post is a day old when you find it.\n\nIt has to answer the post first and bring up your product second. Writing one for every post eats the rest of your day, and tools that post for you get banned.\n\nHow it works\n\nStep 1\n\nGive its site or a description. In under a minute the AI writes 3 to 7 theses: the problems your product solves and the needs it meets. You edit them.\n\nStep 2\n\nSignalsFlow picks posts whose authors have one of those problems, whatever words they use. Each is scored 0–100, with what its author wants. What came since your last visit is marked new.\n\nStep 3\n\nOne click, and the AI writes five comments that answer the post and suggest your product, or a longer reply under the subreddit's rules. Pick one, edit it if you like, and post it from your own account.\n\nWhat you get\n\nEach post shows a score from 0 to 100, what its author wants — a recommendation, an alternative, a way out of a struggle — and the problem of yours it fits.\n\nFor a post, the AI writes five comments of different lengths. Each answers what the author asked and suggests your product as a way to solve it. Edit one, copy it, mark it answered.\n\nFor a longer reply, the AI reads the rules of the subreddit and its thread, and says how you are tied to the product.\n\nMark a post not a fit, answered or skipped, and it leaves the feed. Counters show how each thesis does.\n\nAdd the subreddits your buyers read, on top of the ones every feed shares. Up to 50 of your own.\n\nIn numbers\n\nPricing\n\nNo card, no invite and no trial clock. Instead of a price, the beta has limits for each user.\n\nBeta\n\n$0 a month\n\nThe limits of a day start over at 00:00 UTC.\n\nFAQ\n\nNo, and that is the point. Most people who need your product have never heard of it. The feed finds posts where someone has a problem your product solves or asks for what it does, whatever words they use.\n\nThe AI. For a post it writes five short comments, or a longer reply under the subreddit's rules. Each answers what the author asked and suggests your product. You read it, edit it if you like, and post it.\n\nNo. It only reads public subreddit pages. You copy the reply the AI wrote and post it from your own account.\n\nNot for SignalsFlow: it never signs in to Reddit. You need your own account only to post your replies.\n\nA shared set that every feed draws on, and the subreddits users add. You can add up to 50 of your own; busy ones are checked more often than quiet ones.\n\nYour product's site or description to write the theses, the public posts it scores, and for a reply, the post with its subreddit's rules and thread.\n\nWith Google. No invite, no card and no password; SignalsFlow keeps only the email and the name your account gives it.\n\nSignalsFlow works and is free while it is in beta. It changes often, and each user has limits instead of a price.\n\nBeta · free\n\nAdd your product: SignalsFlow finds the people it can help, and the AI writes your reply to each of them.\n\nFree during the beta · Sign up with Google", "url": "https://wpnews.pro/news/find-a-reddit-post-where-your-saas-can-help-ai-writes-the-comment", "canonical_source": "https://signalsflow.apposters.com/", "published_at": "2026-10-12 20:24:14+00:00", "updated_at": "2026-10-12 20:51:06.300683+00:00", "lang": "en", "topics": ["ai-tools", "ai-products", "generative-ai"], "entities": ["SignalsFlow", "Reddit", "Google"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/find-a-reddit-post-where-your-saas-can-help-ai-writes-the-comment", "markdown": "https://wpnews.pro/news/find-a-reddit-post-where-your-saas-can-help-ai-writes-the-comment.md", "text": "https://wpnews.pro/news/find-a-reddit-post-where-your-saas-can-help-ai-writes-the-comment.txt", "jsonld": "https://wpnews.pro/news/find-a-reddit-post-where-your-saas-can-help-ai-writes-the-comment.jsonld"}}
