If you're researching Delphi AI pricing for coaches, you've probably run into a contradiction. The platform's help documentation and its public pricing page don't agree on a critical point - whether Builder and Scaler plan users can monetize their AI twin and what revenue share Delphi takes.
Here's what the numbers actually show. We dug into Delphi's pricing structure, revenue sharing model, and how it compares to Coachvox, BuddyPro, and Personify for coaches who want to sell $1,000 to $2,000/year AI subscriptions.
What Does Delphi AI Actually Cost for Coaches?
Delphi offers three tiers, with pricing published for two of them (per delphi.ai/pricing, checked August 2026):
- Builder Plan: $99/month, or $79/month billed annually ($948/year). Includes 5 million training words, chat and voice capabilities, and 2 embedding locations.
- Scaler Plan: $349/month, or $299/month billed annually ($3,588/year). Adds a custom domain, professional voice options, more contact capacity, and 10 embedding locations.
- Immortal Plan: Custom pricing only. Delphi does not publish this tier's cost.
One constraint coaches often miss during signup: Delphi requires you to create a new Delphi-connected Stripe Express account. You cannot link an existing Stripe account. Native subscription billing is USD-only, which complicates things for coaches with international audiences who pay in other currencies.
The fixed monthly costs are competitive with other platforms in this category. But the revenue share model changes the total cost picture significantly once your subscriber count grows past the early stage.
Does Delphi Take a Revenue Share Cut?
Yes - with an important caveat about which plans it applies to and a contradiction between Delphi's help documentation and its pricing page.
Delphi's help documentation explicitly states a 15% revenue share on Builder and Scaler subscriptions (per docs.delphi.ai, checked August 2026). On a $1,500/year coaching subscription, that's $225 going to Delphi per subscriber per year, before any Stripe payment processing fees.
Here's the complication: Delphi's current public pricing page lists "Monetization" as a feature available only on the Immortal plan - the custom-priced top tier. Builder and Scaler pages don't visibly include it. This creates a direct contradiction between the help center documentation and the pricing page that Delphi has not publicly resolved.
The practical implication: before signing up for any Delphi plan, get written confirmation of three things from their team. First, whether your specific plan supports native paid subscriptions at all. Second, the exact revenue share percentage that applies to your plan. Third, whether Stripe processing fees are charged on top of the 15% or included within it.
At scale, the 15% fee is the dominant cost variable. If Delphi's help documentation is accurate and Builder and Scaler users pay it, a coach with 100 subscribers at $1,500/year pays $22,500 in revenue share per year - more than 23 times the annual Builder plan cost. If monetization is only available on Immortal, the custom pricing conversation becomes the relevant one.
How Do Delphi's Costs Compare to Coachvox and BuddyPro?
Here's how platform costs stack up at $1,500/year per subscriber, using each platform's annual billing rate. Delphi uses Builder plan pricing and the 15% revenue share from help documentation. Coachvox uses its published 10% platform fee plus 2.9% Stripe. BuddyPro uses its $2,364/year license and the approximately $300/subscriber/year average AI usage figure.
Subscribers | Revenue | Delphi Builder + 15% | Coachvox + 12.9% | BuddyPro (0% share) |
10 | $15,000 | $3,198 (21.3%) | $2,931 (19.5%) | $5,364 (35.8%) |
50 | $75,000 | $12,198 (16.3%) | $10,671 (14.2%) | $17,364 (23.2%) |
100 | $150,000 | $23,448 (15.6%) | $20,346 (13.6%) | $32,364 (21.6%) |
Sources: Delphi figures include $948/year Builder annual plan plus 15% revenue share per docs.delphi.ai. Coachvox includes $996/year ($83/month annual) plus 10% platform fee and 2.9% Stripe per support.coachvox.ai, checked August 2026. BuddyPro includes $2,364/year license plus $300/subscriber/year average AI usage per pro.buddy.fm, checked August 2026. Stripe transaction fees for Delphi and BuddyPro payments are excluded as exact applicable rates are not published by either platform.
BuddyPro appears most expensive at low subscriber counts. That relationship changes as subscription price increases. BuddyPro's AI usage cost stays roughly constant at about $300/subscriber/year regardless of what you charge. At $1,000/year per subscriber, that AI cost represents about 30% of revenue. At $2,000/year, it drops to roughly 15%. Percentage-based platforms like Delphi and Coachvox work the opposite way - the more you charge per subscriber, the more they take in absolute terms.
Coachvox charges $99/month ($83/month billed annually) with a documented 10% platform fee plus 2.9% Stripe processing (per support.coachvox.ai, checked August 2026). Multiple currencies and billing intervals are supported. Coachvox also documents an external paywall approach that may bypass the 10% fee, though they don't confirm this in writing. See our full Coachvox pricing breakdown for details.
A fourth option worth factoring in: Personify Pro costs $39/month or $29/month annually ($348/year) - the lowest published fixed cost in this category (per personify.fyi/ai-clone-pricing/, checked August 2026). However, Personify does not publicly disclose its commission or revenue share for Pro plan native subscriptions. Only their Done-For-You tier explicitly states no Personify commission.

What Should Coaches Ask Before Signing Up?
Platform pricing pages rarely tell the full cost story. Before committing to any AI coaching platform, send these six questions to the vendor in writing and wait for written answers before signing:
- Does your platform take any commission or revenue share on subscription payments from my coaching subscribers?
- Is payment processing deducted on top of the published platform percentage, or included within it?
- Can I collect full annual amounts upfront from subscribers?
- Who is the merchant of record - the platform or me?
- Who controls subscriber billing data, and can I access and export it at any time?
- Can I export subscriber records, conversation history, and training data if I switch to another platform?
These questions become more consequential as your subscriber base grows. A 15% revenue share on $150,000 in annual subscriptions costs $22,500/year in platform fees in addition to your fixed plan cost. A flat licensing model at the same scale costs only the fixed annual license regardless of how much you charge per subscriber. The crossover point depends on your pricing strategy and growth trajectory.
The coaches who build profitable AI subscriptions don't win on low platform fees. They win by offering something that justifies $1,000 to $2,000/year - an AI that remembers what subscribers tell it, coaches proactively, and builds the kind of ongoing relationship that monthly group programs and one-time courses cannot replicate. Platform economics matter, but product quality and retention drive the actual revenue numbers. Our AI coaching platform cost-per-subscriber analysis shows how these variables interact across different subscriber counts and pricing tiers.
Delphi AI pricing for coaches in 2026 requires a direct conversation with their team before you can model the real costs. The 15% revenue share is documented in the help center, but the public pricing page places monetization under the custom Immortal tier - that's a contradiction worth resolving before you commit to any plan. Get the answers in writing, apply the six questions above to every platform you're evaluating, and run the cost model at your target subscriber count and subscription price before signing.
