PaidOnTime new
Spending my Sundays chasing unpaid invoices. How do you handle it?
r/freelance · 2 hours ago · 23 comments
I have 9 clients and 3 of them pay late every month. Reminder emails by hand eat hours, and I hate writing them.
86 struggles with it
Getting paid on time 86
The reply the AI wrote
Same here with two clients. What fixed it was reminders on a schedule, not by mood: on the due day, then a week and two weeks after. I use PaidOnTime for that now, it sends them for me and shows who opened the invoice.
The problem
The people who need your product don't know its name
Keyword alerts miss them
People 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.
Scrolling takes hours
Checking a dozen subreddits by hand eats an hour a day, and the good post is a day old when you find it.
A good reply takes time
It 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.
How it works
From your site to a ready reply in three steps
Step 1
Add your product
Give 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.
Step 2
Get the posts of people who need it
SignalsFlow 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.
Step 3
Let the AI write the reply
One 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.
What you get
The people, and the words to reach them
People with the problem, not mentions
The 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.
A score on every post
Each 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.
Replies the AI writes for you
For 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.
Under the subreddit's rules
For a longer reply, the AI reads the rules of the subreddit and its thread, and says how you are tied to the product.
A feed you clear
Mark a post not a fit, answered or skipped, and it leaves the feed. Counters show how each thesis does.
Your subreddits
Add the subreddits your buyers read, on top of the ones every feed shares. Up to 50 of your own.

FAQ
Before you sign up
Does it find only posts that mention my product?
No, 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.
Who writes the replies?
The 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.
Does SignalsFlow post to Reddit for me?
No. It only reads public subreddit pages. You copy the reply the AI wrote and post it from your own account.
Do I need a Reddit account?
Not for SignalsFlow: it never signs in to Reddit. You need your own account only to post your replies.
Which subreddits does it read?
A 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.
What does the AI read?
Your 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.
How do I sign up?
With Google. No invite, no card and no password; SignalsFlow keeps only the email and the name your account gives it.
What does the beta mean?
SignalsFlow works and is free while it is in beta. It changes often, and each user has limits instead of a price.
