For marketing teams, brands and agencies. Its plans pair prompt tracking with indexing submissions, website audits and monthly articles, and an agency bundle manages several client projects under one bill.[1]

Where each shines
Both tools are built well for different teams. Each point is a strength, read from that vendor's own pages.
Where Indexly shines
- SEO and AI search in one subscription. Indexly adds indexing submissions, SEO and AI readiness audits, backlink intelligence and article writing to its AI tracking on one self-serve bill. Proofsource runs site readiness audits and drafts content in the product, and on Managed its team writes and publishes the articles for you.[1]
- Several countries on the entry plan. The AI Visibility plan tracks 100 prompts across 2 sites and 2 countries of your choice.[1]
- Social and forum agents. Its social agents publish posts and threads, and its Reddit and LinkedIn work targets the off-site sources AI answers lean on.[2]
Where Proofsource shines
- All four main engines by default. Proofsource asks ChatGPT, Perplexity, Claude and Google AI Overviews on the trial and by default on every plan, where Indexly's AI Visibility plan tracks the 3 models you pick.
- Intervals before alerts. Every Proofsource rate carries a 95% Wilson interval, and an alert waits until a change clears it. Indexly's pricing page does not describe how it handles run-to-run variation.
- A trial you can run alone. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call. Indexly's pricing page does not publish a trial.
Proofsource or Indexly: the fair verdict
If you want one tool for SEO indexing, audits and content production as well as AI tracking, Indexly covers more ground for one monthly price.
If you need to trust the AI visibility number itself, Proofsource is the stronger pick: four engines by default, an interval on every figure, and a draft fix built from the pages that beat you, held for your approval.

You do not have to choose on day one. Here is how teams run Proofsource beside Indexly and decide on their own data.
Keep Indexly running
Nothing about trying Proofsource needs you to stop Indexly. Your history and reports there stay where they are.
Bring your questions across
Export or copy the prompts you track in Indexly and add them as buyer questions in Proofsource, so both tools ask the same things.
Run both side by side
Read the two for the same days on your own domain. Where the numbers differ, Proofsource shows the answers and the pages each engine cited, so you can see why.
Keep what serves your team
Many teams keep one tool for reporting and another for fixes. Pick on your own evidence, not on a comparison page.
Proofsource or Indexly: what buyers ask
What are the best alternatives to Peec AI for tracking prompt variations and AI answer coverage?
Some AI answers to that question named Indexly. From its own pricing page: prompts tracked daily on 3 models you choose, from $99 a month. Proofsource asks each buyer question on ChatGPT, Perplexity, Claude and Google AI Overviews and shows, question by question and engine by engine, where your brand is named and where it is left out. We have not verified Peec AI's plans here; check its own pricing page.
What's the best way to benchmark my brand's share of AI citations against category leaders?
Ask the same buyer questions on the engines your buyers use, every day, and compare rates that carry their margin of error. Indexly tracks prompts daily on the 3 models you pick and adds citation gap analysis. Proofsource names who is cited instead of you on each question and puts a 95% interval on each rate, so a gap to the leader is a measured difference.
How much does Indexly cost?
Its pricing page lists Starter at $99, Growth at $299 and Scale at $499 a month billed monthly, with 17% off for annual billing and custom plans on request.
Does Indexly have a free trial?
Its pricing page does not publish one. Proofsource's trial: 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card.
