What it is
GravityAgent is a Gravity Forms add-on that scores each submission for spam before notifications fire, through a hosted service that needs no API key, learns from the site owner's Spam and Not Spam corrections, and never marks an entry spam without a clean verdict from that service.
Built for
Three ways in. One rule that never bends.
Only a clean verdict from our service can mark an entry spam. Everything else gets through. Agencies, procurement, the one-site owner: same rule, no exceptions.
Agencies
Running 25 client sites? One license.
No API key to paste into 25 wp-admins. No per-site setup routine. One Agency license covers 25 sites, each activated from its own settings page and each learning from its own corrections. And the privacy policy and DPA are public pages you can forward to a client's IT contact without editing a word.

Procurement will like this one.
We never store submission content. Not in a database, not in a log, not in a cache, not in a backup. Your WordPress site is the controller and GravityAgent is a transient processor. Stored data is US-only, and nothing trains a model. Ever.

Install freeHow it works
Four steps. The fourth is the clever one.
Scoring stays off until you turn it on for a form. Forms you haven't switched on make no call at all.
Step 01
Install
Install the plugin beside Gravity Forms 2.6 or later. Same as any other add-on.
Step 02
Activate
Open Forms → Settings → GravityAgent and press Activate on the Free plan. No license key, no card, no provider account. GravityAgent reads your public pages and builds a profile of your business by itself.
Step 03
Turn scoring on
Open a form's GravityAgent tab and turn scoring on. Tick any field under Fields to keep on this site and its value never leaves your site. Ever.
Step 04 · repeats
Correct when needed
Wrong call? Press Spam or Not Spam on the entry, like you already do. That's the whole setup. Every correction informs future decisions.
Checked
There is no API key anywhere in this procedure. Read it again if you like.
What you see in wp-admin
Nothing new to learn. Five screens you already know how to read.
A column on the Entries table and a panel on each entry. Behind them, the settings page, the per-form tab, and what you see on the rare day we're the problem.
| Entry | Time | Form | Message | GravityAgent |
|---|---|---|---|---|
| #1044 | 14:01 | Contact | Do you fit implants for a patient who… | Passed4%Why? |

The GravityAgent column: the verdict, the spam likelihood, and a link to the reasoning. Sample entries.
The message offers search-ranking services to the site owner and asks nothing about the practice. It matches the shape of two entries you marked Spam on this form.

Fields to keep on this site
Name
Phone
Message
Date of birth
Tick a field to keep its value on this site. Ticked values are never sent to GravityAgent; the entry still records them in full, and the rest of the submission is still scored.
Turn scoring on per form, and keep any field on this site. A ticked value never leaves your site, including in the correction examples sent later. File uploads are sent as a file name and field label only.
Not scored
GravityAgent did not answer within its 3-second budget, so this submission was admitted without a decision.
The one thing we never trade away: no verdict, for any reason, means the entry gets through with the reason written on it. Nothing for you to do. The next submission on this form is scored as usual.

Failure modes
Fail-openEvery one of these lets the entry through, marked Not scored with the reason, and marks nothing spam. It lands on your Entries table like any other, Not scored in the GravityAgent column. Only a clean, well-formed verdict from our service can mark an entry spam. Something else already marked it spam? We leave it alone and make no call.

Founder
NoteA spam filter that eats a real inquiry does more damage than one that misses a spam. So GravityAgent has one rule it never trades away: only a clean verdict from our service can mark an entry spam. A timeout, an outage, a reached limit, a malformed response, or a bug in our own code admits the entry and flags it Not scored, with the reason on the entry. We measured it the same way: 0 false positives on 95 genuine submissions on our benchmark, and 87.2% of the spam caught. If the rule is ever broken on your site, that is a bug, and we want to hear about it.

Rows you can trace. Our column is the fact sheet. The other four are each category as its own vendor documents it.

FAQ
The questions people ask before they switch a form on.
Shorter versions of the plugin listing's answers. Same facts, fewer words.
Does GravityAgent replace my CAPTCHA or honeypot?
It can. GravityAgent judges what was written, not whether a human typed it, and asks nothing of your visitors. It also works alongside whatever you already run: an entry another filter has already marked spam is left alone, and no call is made.
What happens if the service is down?
It gets through. The entry is admitted and flagged "Not scored", with the reason recorded on the entry. Nothing is marked spam because we had a bad day. There is nothing for you to do.
What does GravityAgent store?
Never the submission content. GravityAgent keeps a non-content record of each decision (ids, label, confidence, model, latency, tokens) for about 90 days, daily outcome counts, and the site profile and description until the site is deactivated. Entries stay in WordPress.
How are sites counted?
Each WordPress site activates separately from its own settings page and takes one slot on the license. Growth has 5 slots and Agency has 25. The settings page lists the sites using the license and lets you free a slot.
Is there an API key to paste?
No. There is no provider account to open and no key to paste, on any plan. Activation sends the site's domain and, on a paid plan, the license key and merchant identifiers, and gets back a token the plugin keeps. That's the whole handshake.
Does GravityAgent slow down my forms?
One request per submission, with a ceiling of 3 seconds and no retries. If no answer has arrived by then, the entry is admitted and flagged "Not scored". Forms you have not switched on make no call at all.
Which fields are sent?
Every field on a scored form, except the ones you tick under Fields to keep on this site. Passwords and presentation fields are never sent. A file upload is sent as its file name and field label only.
What happens when a month runs past its limit?
Scoring stops after a 10% grace allowance and submissions come through, marked "Not scored". Nothing is ever charged as overage. Upgrading is your call, and an upgrade applies immediately.
Does GravityAgent train a model on my submissions?
No. Your corrections are sent as examples with that form's later submissions on that site and inform its future decisions. No model is fine-tuned, and nothing from your site serves another customer.
