UserEvidence alternatives for customer proof
One approach asks for new answers. The other starts with evidence you already have.
UserEvidence gathers customer proof by surveying customers directly and turning their verified answers into shareable evidence — stats, quotes and one-page assets for buyers. Casily starts with evidence you already have: reviews from Google, Trustpilot, G2 and Clutch, existing case studies and website content, and what customers say on calls. It brings those sources into one library, keeps every claim traceable, gets drafted proof confirmed, and puts usable proof into sales and marketing work. Which approach suits you depends on whether your proof problem is collecting a new dataset or making better use of material that already exists.
What the survey approach does well
Structured customer surveys have real advantages, and they are the reason the category exists:
- You get comparable, quantified answers across many customers, which is how you end up with defensible aggregate statistics.
- The evidence is attributable and verified at the point of collection, which matters to a sceptical buyer and to a legal reviewer.
- It works even when you don't have recorded conversations to draw on — a fresh dataset is created on demand.
- It produces assets that sales can hand over immediately without a writing step.
If you want a benchmark-style number across a customer base, asking everyone the same question is the right way to get it.
What it costs you
Every survey is an ask. Response rates set the ceiling on what you can collect, the customers most willing to answer are not always the ones with the best story, and the evidence is a snapshot of the day they replied. Meanwhile useful material may already be scattered across public reviews, published case studies, website pages and call transcripts that nobody revisits.
How Casily approaches it
Casily works from evidence you already have. It imports public reviews with their attribution and original link, reads existing case studies and website content, and extracts proof-worthy passages from customer call transcripts. It can turn that material into case study or testimonial drafts, with every figure and quote linked back to its source. Nothing drafted leaves that state without internal approval.
Then two things happen that surveys don't usually cover. First, the named customer is sent the exact wording to approve, and that approval is tied to the version they read — an edit afterwards is flagged rather than silently carried forward. Second, proof is treated as perishable: Casily flags items that are ageing or whose figures have likely moved on, and gives you a single link to ask the customer to confirm, correct or withdraw what they said.
| Survey-led evidence | Casily | |
|---|---|---|
| Source of proof | Answers you ask customers for | Reviews, case studies, website content and customer calls you already have |
| Best at | Comparable statistics across many customers | Narrative proof drawn from what a customer actually said |
| Effort per item | Designing and fielding a survey | Reviewing a draft that was written for you |
| Approval record | Verified at collection | Bound to the exact version the customer approved |
| Staying current | Re-field the survey | Ageing proof is flagged; one link to confirm, correct or withdraw |
Which one you want
- You need a headline statistic across hundreds of customers: a survey-led tool is the better fit.
- You have scattered reviews, case studies, website content and customer calls but no coherent proof library: start by bringing it together.
- Your published proof is two years old and you're not sure it's still true: the currency problem is what Casily is built around.
- You need to prove a customer signed off on specific wording: that record is what approval tracking exists for.
They are not mutually exclusive. Nothing stops you from surveying for benchmark numbers while bringing reviews, existing content and customer calls into one traceable proof workflow.
What happens when the source is a call transcript
Proof-relevant passages are extracted and the raw transcript is then discarded, kept seven days, or retained, according to a per-workspace setting that defaults to seven days for new workspaces.
Frequently asked questions
Is Casily a survey tool?
No. Casily can send a customer a request for a testimonial or confirmation, but it does not field structured surveys across a customer base. It starts with reviews, existing case studies, website content and customer call transcripts you already have.
Can we use both approaches together?
Yes. Surveys are good at comparable answers across many customers. Casily is built to organise and activate the reviews, existing content and customer conversations you already have. There is no conflict between using both approaches.
How does Casily prove a customer approved something?
Customer approval is a separate gate from internal approval, and it is bound to a hash of the exact wording the customer saw. If the text is edited after sign-off, Casily flags it as changed since approval rather than treating it as still approved.
What does Casily do when a result changes?
It flags proof that is ageing or whose figures have likely moved on and gives you one link to send the customer so they can confirm, correct or withdraw what they said. Withdrawn proof stops being usable.
