“CPA is up 38% since Friday. Did something change over the weekend?”
You open Ads Manager. You filter by date. 17 events. 45 minutes later, you reply. You kept the client — barely.

Evida is a Chrome extension that shows every edit made in Meta Ads Manager — who, what, when, and the performance impact — inline next to your Facebook and Instagram ad campaigns, plus Slack alerts when something important changes. Built for agencies and in-house media teams. Pricing scales with your client book, not your team size.

The three Mondays
You know this Monday.
Three conversations every Meta Ads team walks into unarmed. The tool exists so you don't have to.
Paid media lead
Tuesday · 11:47 AM
“Who set budget to $2,000/day instead of $200?”
A missing zero. $1,800 burned before anyone noticed. You'd know in 45 seconds, not 4 hours — with the actor's name and a one-click rollback URL.
Senior buyer
Sunday · 9:12 PM
“Why is the winning creative off? It was doing 5 ROAS.”
Someone paused it during the Saturday audit. No note, no Slack message. On Monday, CPA is 2× and nobody's sure what to unpause first.
Why it works
Three layers, one job: defensibility.
Not "activity history." Change intelligence — so the edit, the actor, and the performance impact land in the same line.
Layer 01 · See
Inline badges, right on the campaign row.
Every edited campaign gets a badge the moment it changes — inside the Meta Ads Manager you already use. No dashboard-switching, no tab juggling, no clicks to find who changed what.
- Works on every row in every account view
- Normalized actor matching — "only my edits" actually works
- Click the badge for the full diff — before → after

Layer 02 · Know
Slack alerts framed in dollars, not events.
Don't tell me "budget changed." Tell me someone bumped it +40% on a campaign still in learning — and that's projected to burn $2,100 more this week. Every alert has a dollar-impact line so you can triage without opening another tab.
- Off-hours edits, learning-phase pumps, attribution flips
- Unlimited rules on Studio+ — route by client, by buyer, by severity
- Jump from Slack straight to the edit in Ads Manager — with the diff pre-open

Layer 03 · Prove
Every edit, tied to the performance delta that followed.
The edit happened. Did it matter? We track CPA, ROAS, and spend in the 24–72h window after every change — so you walk into the client call with the timeline, the actor, and the number. Screenshot it into the thread. Conversation over.
- CPA / ROAS / spend delta on every edit
- 12 months of history on Agency tier — survives EOM reporting
- White-label client PDF export (agency logo, not ours)

What agencies say
Stops fires you didn't know were burning.
Early users running real client books. Real quotes, light edits for length.
★★★★★
Caught a $2k/day budget typo within 4 minutes. Slack alert popped while the buyer was still on the edit screen. That one save paid for the year.
★★★★★
We used to lose 30 min every Monday standup just reconstructing the weekend. Now the extension shows it inline — who, what, when — no debate.
★★★★★
I pause and unpause 50 ads a day. Having the CPA delta right there next to the name tells me in 2 seconds if I made the right call. Can't go back.
★★★★★
The "outside active hours" alert caught a contractor making changes at 2am on a Saturday. Old-us wouldn't have found out till Monday morning panic.
★★★★★
Rolled it out to my team of 6 on Monday. By Friday, nobody was asking "who changed this?" in the group chat. The chat went quiet. That's the ROI.
★★★★★
The thing I didn't expect: it made my juniors more careful. Knowing an alert fires if they touch budget past 1.5x, they double-check. Cut mistakes in half.
Pricing
Pricing that scales with your client book, not your team size.
Most tools charge per seat — which punishes you for hiring. We charge per account, because that's what actually grows.

Evida vs the alternatives
Why agencies pick Evida over Triple Whale, Motion, or Meta's native log.
The honest comparison. We're not trying to be an analytics platform — we're the change intelligence layer your analytics platform doesn't have.
| Capability | Evida | Triple Whale | Motion | Meta native log |
|---|---|---|---|---|
| Inline change badges in Ads Manager | — | — | — | |
| Real-time Slack alerts with dollar impact | Basic digests | — | — | |
| Multi-account cross-client feed | One account at a time | |||
| Edit → performance correlation (24–72h) | — | Creative-level only | — | |
| Pricing for a 10-client agency | $199/mo | $1,500+/mo | $1,200+/mo | Free (and painful) |
| Install time | 30 seconds | 2–4 weeks | 1–2 weeks | 0 (native) |
Triple Whale and Motion are great analytics platforms — that's not us. Evida is the change intelligence layer: who edited what, when, and the performance delta that followed. Use Evida alongside your analytics stack.
FAQ
Answers to the real objections.
Written in practitioner voice. No marketing fluff.
Is Evida free?
Yes. The Free tier includes 1 ad account, 7 days of change history, and inline badges in Meta Ads Manager — no credit card, no email required. Paid tiers start at $19/mo (Solo) and unlock multi-account tracking, Slack alerts, and edit-to-performance correlation.
Does Evida work with Instagram ads too?
Yes. Evida reads from the Meta Ads API, which covers every ad account that runs on Facebook and Instagram — feed, Stories, Reels, Shops, Messenger. If it's in Meta Ads Manager, Evida tracks edits on it. One change log for both platforms.
Can multiple team members use Evida?
Studio includes 5 seats, Agency is unlimited seats, Network is unlimited. Every buyer installs the extension on their own Chrome, logs in to the shared Meta Business accounts, and the actor normalization engine matches every edit to a real human — so "who changed this" always has an answer.
Is my Meta API token safe?
On the Free tier, the token stays in chrome.storage.local and never leaves your browser. On Studio and above (where correlation and cross-client dashboards live), we store it encrypted at rest and only read the scopes you grant. You can revoke access from your Meta Business Settings at any time. Full details: privacy policy.
Does Evida need approval from Meta?
No. Evida uses Meta's public Graph API with read-only scopes that you authorize with your own token. There is no Meta app review required for customers — you install from the Chrome Web Store, paste your token, and you're done. Evida never writes back to your ad accounts.
Does Evida work in Chrome, Edge, and Safari?
Chrome and Chromium-based Edge are supported today — same extension, same Chrome Web Store listing. Safari is not supported (Apple uses a different extension platform). Firefox is on the roadmap. If you're on Arc, Brave, or Vivaldi, you're covered — they all accept Chrome Web Store extensions.
Why not just use Meta's native change log — it's free?
Because it's 3 clicks deep, one account at a time, and has no alerts. For a solo with 2 clients, the native log is fine. For an agency with 10 clients, you'll open 10 tabs to answer one client's question. We're not better than native — we're faster.
Do I have to give you my Meta API token?
The token stays on your machine. Nothing syncs to a server on the free tier. For Studio+ (where we do correlation and cross-client dashboards) we store the token encrypted and only read what's needed to build the log. You can revoke access from your Meta Business Settings any time.
Full details: privacy policy.
Is this compliant with Meta's platform terms?
Yes. The extension uses Meta's public Graph API with read-only scopes (ads_read, ads_management — we never write back to your accounts). You authorize your own token; we don't scrape the DOM, don't bypass rate limits, and don't proxy your traffic. Data goes directly from your browser to graph.facebook.com.
My agency does 100+ edits per day on one account — will your limits bite?
No. Account limits mean distinct ad accounts, not edits. We log every edit on every connected account, regardless of volume. Retention windows apply (7d Free, 30d Solo, 90d Studio, 12 mo Agency+) but volume does not.
What's the difference between Studio and Agency? They look similar.
Three things. Agency gives you (a) unlimited team seats instead of 5 — so your junior AMs don't cost extra, (b) white-label client-facing digests — send weekly "what we did" reports with your agency's logo, and (c) 12 months of history for EOM reporting. Studio is for teams still growing. Agency is for teams billing clients.
Can I cancel anytime?
Yes. Monthly plans cancel immediately at period end. Annual plans — we'll refund the unused months minus the 2 months of annual discount. 30-day money-back guarantee, no questions asked. No "contact us to cancel" — there's a button in your dashboard.
Does this work with Google Ads or TikTok Ads?
Not yet. Meta-only by design — depth over breadth. Google Ads is on the 2026 roadmap. TikTok is not.
What happens if Meta changes their API or Ads Manager UI?
We update within 48 hours of any breaking change. It's our core dependency and we monitor it continuously. If we can't adapt in 48h (hasn't happened), we credit that week back.
