StoryVoice comes first because it is the only option here built for customer case studies alone. The agencies after it are the ones buyers and AI answers name alongside StoryArb. We opened each vendor's own pages on 2026-10-16, and where a price is not published we say so.
In one sentence. Software that interviews your customer by voice, writes the case study, gets her approval and makes four sharing assets.
How it works. A voice AI interviews your customer for about 5 minutes. StoryVoice writes the case study with each number it pulls from the interview linked to the sentence she said it in, sends it to her for approval, and adds a LinkedIn post, an X post, a pull quote and a sales email.
Pricing.
- →One story $39, 3-pack $99, 5-pack $149. Credits never expire.
- →Agency plan $249 a month for 50 case studies.
- →Free trial: interview yourself and read a finished case study, no credit card.
What's good.
- →No retainer, no minimum term and no kickoff: you can send the first interview today
- →The case study is written minutes after the customer finishes, not weeks after a call
- →The customer approves by link, with no account, so sign-off does not stall in email
- →Every interview also gives you a LinkedIn post, an X post, a pull quote and a sales email
Best for. Teams whose gap is customer case studies and who want to pay per story.
Skip if. You need newsletters, executive thought leadership, filmed customers or a human strategist. StoryVoice is text only and built for customer stories.

What's good.
