Prove your fix changed the answer, then share the proof
Proofsource records what AI engines said before a fix and checks again on day 7, 14 and 28 after it ships. The result is a proof receipt and a frozen replay of the before and after answers that you can share by link with anyone. It is built for marketers and agencies who need to show that their AI search work actually moved ChatGPT, Perplexity, Gemini, Copilot or other AI engines.

Before and after AI answer proof, explained
Before and after AI answer proof is evidence that a specific change, such as a new page, a corrected fact or a fresh citation, changed what AI engines say. It pairs the answer an engine gave before the change with the answer it gives after, for the same buyer question.
Proof matters because AI answers move for many reasons. Without a dated before and a checked after, it is easy to claim credit for noise, or to miss a fix that worked. Checking more than once also matters, since engines pick up changes at different speeds.
Proofsource dates every shipped fix, then checks the same questions on day 7, 14 and 28. Each verified result becomes a proof receipt with the before and after answers, and any time range can be frozen into a replay. Receipts, wins, replays and live fix views can all be shared by unlisted link, so a client or a boss sees the evidence for themselves.

Questions about before and after AI answer proof
How do I prove an AI search fix worked?
Mark the fix as shipped. Proofsource asks the same buyer questions on day 7, 14 and 28 and compares the answers with the ones recorded before the fix.
What is a proof receipt?
A short record of one fix, with the answers before and after, the date it shipped and the verdict from the follow-up checks.
Can I share proof with a client who has no account?
Yes. Receipts, wins and replays open by unlisted link with no sign-in.
Does the shared replay change if new answers come in?
No. A replay is frozen to the time range you chose, so it always shows what you sent.
Which engines can I prove changes on?
Every engine your plan covers, up to 10: ChatGPT, Perplexity, Claude, Google AI Overviews, Google AI Mode, Gemini, Microsoft Copilot, Grok, DeepSeek and Meta AI. The free trial runs four.
Why check three times?
Engines pick up changes at different speeds. Checking on day 7, 14 and 28 shows whether a change happened and whether it held.
What is Your week in 60 seconds?
A weekly link to a frozen replay of the brand's week, so you can catch up in a minute.
How is this different from answer history in other tools?
Tools such as Ahrefs and Scrunch keep strong answer history. Proofsource ties each before and after to a dated fix, checks it three times and packages the result as a shareable receipt.
