When they check
One Stop Social checks your groups every 2 hours by default, and you can change the schedule in its settings. GroupSignal doesn't wait for a schedule: while Chrome is open and signed in to Facebook, it keeps reading your groups one after another at a steady pace and sends each new post for an AI check. Alert times still vary, and neither checks while Chrome is closed. When Chrome opens again, GroupSignal catches up on posts from up to the last 24 hours, and Sosaly shows any gap it couldn't cover.
Where you review matches
One Stop Social stores your leads in your browser, with browser notifications and email alerts, so you work through them on the computer that found them. GroupSignal sends matches to your inbox at sosaly.com, which works on any signed-in device, including your phone, and shows why each post matched. You can open the post on Facebook or save it to follow up.
How they find posts
One Stop Social combines keywords with an AI search you describe in plain language. GroupSignal uses no keywords: you write who and what to find, and what to ignore, and AI reads every new post against that, by meaning and in any language (why keywords miss posts).
What they cost
One Stop Social Premium is $29/month, or $249/year, for 25 groups. GroupSignal is $10/month for five group slots and $2/month for each extra slot, up to 25. A slot is one group in one active monitor, so watching each group in one monitor costs $2 a group: 10 groups cost $20/month and 25 cost $50/month. Up to 14 groups, GroupSignal costs less; from 15 groups, One Stop Social's monthly price is lower. Both offer 7 days free without a card.
Which to choose
- One Stop Social if you watch 15 or more groups and a check every couple of hours is enough, or you want keyword alerts.
- GroupSignal if you want your groups read continuously while Chrome is open, posts matched by meaning, and an inbox you can check from your phone.
