In short
LeadScanner is the fit when you need public Facebook monitoring without any Facebook account, plus separate client campaigns. Groups Watcher suits work that requires private groups or rapid alerts. Devi AI suits teams that prioritize broader network coverage and can use a signed-in Facebook session.
LeadScanner vs Groups Watcher and Devi AI: the main difference
LeadScanner reads public Facebook groups and public pages as a signed-out visitor. It does not use a customer's Facebook account or its own account, does not require a browser extension, and does not read closed groups. It scans sources on a schedule, reads the posts that are visible, and reads comments under those posts.
Devi AI has a broader network scope. Based on available information, it monitors Facebook through the user's signed-in session in an extension, as well as Reddit, LinkedIn, and Twitter. Groups Watcher states that it monitors public and private groups and sends alerts in under 60 seconds to Slack, Discord, email, and webhooks.
LeadScanner reads public content without using a Facebook, Reddit, or X account on either side.
architectureA Devi AI alternative without a Facebook account
If you are looking for a Devi AI alternative because you do not want to connect your Facebook session, LeadScanner uses a different access model. It reads only what Facebook shows a visitor who is not signed in. It does not ask for a login, password, session cookie, or browser extension. There is no Facebook account behind the scans, either.
The tradeoff is clear: LeadScanner cannot see content that is available only after sign-in and cannot enter private groups. Devi AI is the better fit when you need one tool across several networks, especially LinkedIn, Reddit, and Twitter, and accept using your own signed-in session. LeadScanner fits when public Facebook groups and pages are the source and the access boundary needs to remain clear.
Groups Watcher alternative for private groups and fast alerts
Groups Watcher is a better choice than LeadScanner if your work depends on private groups. LeadScanner never reads them. A closed group is outside the scope regardless of plan, point balance, or client. We also do not collect reaction lists, contact details, or member exports because that information is not visible in the signed-out view.
According to information on the Groups Watcher site, its product monitors public and private groups, does not require an account, and sends alerts in under 60 seconds. If responding almost immediately after publication matters most, compare that model with LeadScanner's scheduled scans. LeadScanner does not promise alerts within a specified time. It focuses on public sources, intent matching, and an organized sales workflow.
Monitoring public Facebook groups and matching leads
In LeadScanner, posts can be matched with your own keyword phrases or with AI mode. In AI mode, a model scores buying intent from 0 to 100, explains the score, and drafts a reply in the post's language and in your company's voice. Comments under visible posts are read on plans that include AI mode and comments.
One scan of one source uses one point, and an AI scan uses two points. There is no surcharge for scan scope, and points are refunded when a scan fails on our side.
A tool for agencies with several clients
LeadScanner is also built for agencies running separate work for several clients. Each client can have its own workspace, offer profile, sources, notification rules, and time zone. That keeps a roofing company in Chicago separate from a law firm in Austin even when the same team handles both accounts.
The interface is available in Polish and English. LeadScanner is operated by an EU company and provides a data processing agreement. Public posts are still personal data, so history follows the plan's retention period and data is deleted on request. The guide titled “Is monitoring public Facebook groups legal?” explains that boundary in more detail.
Which tool to choose and how to check a group
Choose Devi AI when monitoring several networks is the priority and you can work through your signed-in session. Choose Groups Watcher when you need private groups or its stated sub-60-second alerts. Choose LeadScanner when you monitor public Facebook groups and pages without an account, want to read comments, score buying intent, and run separate client campaigns.
First, check your own group for free on the home page. Paste its link and get a verdict on whether the group is public and readable without a login. Then start LeadScanner's free trial with no card.
Run a like-for-like test
Use one client offer and five real search phrases for every product you evaluate. Include a phrase with clear buying intent, a broad industry phrase, and a phrase likely to produce irrelevant discussion. Write down the public group or page links you expect to monitor before the test begins.
For each result, check four things: whether the source was available, whether the matched text showed a real need, whether comments mattered, and whether a teammate could act on the result. Keep private-group requirements separate. A tool that cannot read required private groups is not comparable for that part of the work.
Set campaign boundaries first
Create one campaign per client before adding sources. Add the client’s offer, service area, exclusions, and phrases that signal a request for help. Set the campaign time zone and decide who receives notifications. This avoids sending a lead for one client to another client’s team.
When reviewing matches, open the original post and check context before replying. A phrase such as “need an accountant” may be a direct request, a referral question, or a complaint. Treat the score and draft as a starting point, then make the final response yourself.
Questions that come with it
Is there a Devi AI alternative that does not use my Facebook account?
Yes. LeadScanner reads public Facebook groups and public pages without signing in to a customer account or a LeadScanner account. It does not require a browser extension or a signed-in session. In return, it does not read private, closed, or sign-in-only content.
Does Groups Watcher read private groups?

Can I try LeadScanner without a card?
