How Much Does Delphi AI Cost? The Real 2026 Prices

The answer, with a date on it#

How much does Delphi AI cost? As of 14 August 2026, checked directly on delphi.ai/pricing: Free is $0, Builder is $79/month, Scaler is $299/month, and Immortal is custom pricing. Disclosure before you read another line: we make hiy, a Delphi alternative — so read the last two sections as a competitor talking, and re-check the Delphi figures on their own page, which is why we linked it first rather than last.

We put a date on that paragraph because the other pages answering this question don't agree with each other. One directory currently lists Delphi at $99 and $399. Another lists a flat $97. Those are not different readings of the same page; at least one of them is simply wrong. The rest of this post is the plan-by-plan breakdown, what the ladder actually meters, and why the aggregators drift.

This is only the price question. We've argued the positioning elsewhere — the direct hiy vs Delphi head-to-head covers features side by side, and the Delphi alternatives survey covers the rest of the category. Neither of them tells you what it costs, so this one does.

How much does Delphi AI cost, plan by plan#

Four tiers, at these prices on the vendor's own pricing page on 14 August 2026:

Builder is the entry paid tier, and as of writing the page lists voice calling, millions of training words, contact collection, analytics and integrations under it. Scaler and Immortal read as more of the same rather than a different kind of product — the ladder is metered on scale and plumbing, not on whether the core capability is switched on. Immortal is quoted rather than listed, which in practice means the ceiling there is a conversation, not a number.

We are deliberately not reprinting Delphi's per-tier limits — the exact word counts, contact caps and seat numbers. Those are the figures that move, and a stale limit in a table is precisely the failure mode this post exists to complain about. They are on the page, one click away, dated by the fact that you are looking at them.

What the ladder does tell you is where the decision sits. If voice, analytics and contact collection start at $79, then the step to $299 buys audience scale and downstream plumbing rather than a capability you were missing. Work out how many people you expect to talk to, and where their details need to land afterwards, and the tier mostly chooses itself.

Why do third-party pages quote different Delphi prices?#

Because most of them were scraped once and never re-checked. A software directory publishes a pricing page, ranks for it, and has no mechanism that notices when the vendor changes a number eight months later. The page keeps ranking. The number keeps being wrong.

You can usually spot the failure mode from the shape of the figure:

• $99 and $399 looks like an older price list, or a list-price-plus-margin guess. It preserves a two-paid-tier structure but inflates both ends.
• A flat $97 looks like a single number lifted from a promotion, a launch-week rate, or a mis-parse of a page that had more than one price on it. A tier ladder collapsed into one figure is almost always a scraping artifact.
• Anything without a date is unfalsifiable. If a pricing page won't tell you when it last looked, it is telling you it doesn't know.

There is a second, quieter reason: nobody is paid to un-publish a wrong number. The traffic arrives on the strength of the query, not the accuracy of the answer, so the incentive to re-check decays to zero the moment the page starts ranking. That is a mechanism, not a conspiracy, and it applies to us too — which is why this page carries a date rather than an air of authority.

The practical rule: for any SaaS price, open the vendor's page before you budget. For Delphi that is delphi.ai/pricing, and if what you see there differs from our table, their page is right and ours is stale.

What does hiy cost instead, and what does it not include?#

hiy has two plans: Free, which publishes a real twin, and Founding Creator at $49/month, which is a founding rate that stays yours as the list price rises toward $79. The 14-day trial is card-free and starts when your twin goes live, so setup time is never trial time. Visitors always chat free — the cost is on the creator, never the audience. The full breakdown is on our pricing page.

Now the part that matters more than the price, because a cheaper number for less product is not a saving:

Delphi has voice calling. hiy does not. Not on any plan, not as an add-on. If your audience should be able to ring your twin and hear you answer, this post ends here and Delphi is your product. We also don't have Slack, WhatsApp, SMS, CRM syncing, a custom domain, or a roster of names you'd recognize. Delphi is the older, larger, more integrated product and pretending otherwise would be insulting.

What $49 buys is a different bet. Every grounded answer carries a citation that opens the passage it came from and links back to the spot on your original page. When a question falls outside your material, the twin says it doesn't know — in your voice — and shows the searches it ran before giving up, then queues the question for you so one answer from you closes the gap permanently. Visitors can leave their details, which land in a People list with a New-to-Won pipeline and a CSV export, and you can open the exact conversation behind a lead. Bookings go through your existing Cal.com or Calendly link.

Crucially, none of the honesty mechanics are behind the paywall. Paying removes the "Powered by hiy.ai" credit and swaps the brand noun for the category noun. It cannot remove the AI disclosure label, the citations, the honest "I don't know", the report link, or the Verified badge — including on the free plan, where they all work exactly the same.

The honest version#

A price comparison between these two products is close to meaningless on its own. $49 against $79 is roughly a 38% difference on a line item that is probably not your largest cost, and Delphi's Builder tier does more things than hiy does. If you total up features, Delphi wins the count.

The question worth asking is narrower: what happens when your twin is asked something you never wrote about? That is the one behavior a pricing table can't show you, and it's the one your audience will judge you on. We built hiy around admitting the gap. Whether that's worth choosing a smaller product for is genuinely your call, and if voice is on your requirements list, it isn't.

What to do next#

Open delphi.ai/pricing and check the four numbers above against what's on the page today — that takes fifteen seconds and it is the whole point of this article. A price you verified yourself beats a price you read somewhere, including this one.

Then, if you'd rather test behavior than read tables, open our live demo and ask it something outside its material. Watch it decline, and watch it show you the searches it ran before it did. That is the property you would actually be buying, and it costs nothing to check.
