Delphi.ai alternatives: an honest comparison (from a competitor)

Disclosure first: we make hiy, a direct Delphi alternative. You should read everything below knowing that — and we've kept it to things you can verify on both products' public pages. If we've got something wrong, tell us and we'll correct it; corrections outranking older claims is literally our product.

What Delphi does well#

Delphi is the category's reference product, and it's earned that. As of July 2026 (per their public pricing page): a free tier to start; a Builder plan at $79/month for professionals with voice calling, chat, millions of training words, contact collection, analytics and integrations; a Scaler tier at $299/month; and a roster that includes genuinely famous experts. If you want your twin to talk on the phone, or you're an established creator monetizing a large audience, Delphi is a serious, polished choice.

Where hiy takes a different bet#

hiy's bet is that the category's binding constraint isn't features — it's trust. An AI answering as a real person is only worth anything if the audience can believe it, so we made the honesty mechanics the product:

• Citations by default, on every plan. A visitor can open the exact passage of your material behind a grounded answer. Never a paid add-on.
• A designed "I don't know." Outside your material, your twin says so in your tone — and the question queues for you; your one-time answer teaches it permanently.
• Corrections that win. Fix a price or a position once; the fix overrides every older source.
• Identity rules with teeth. You may only twin yourself or a product you own; public twins are reviewed, every page is labeled AI and carries a report link.
• Price. Free includes a real published twin. The one paid plan is Founding Creator at $49/month — a founding rate that stays yours — versus Delphi's $79 entry.

What hiy doesn't have today, honestly: voice calling, a celebrity roster, and Delphi's years of scale. If those are your requirements, choose accordingly.

How to decide, whoever you pick#

Run the same three tests on any twin platform, ours included:

1. The receipt test — ask where an answer came from. Can a visitor see the source?
2. The edge test — ask something your material doesn't cover. Does it admit it, or improvise in your name?
3. The exit test — can you read everything it knows, correct it, unpublish instantly, and export or delete everything?

The fastest way to run those tests on hiy is the live demo — including the edge case, which we've deliberately left in. Then build yours free and run them on your own material.
