The bottom line
Try the free plan first; the $5,000 annual starting price is hard to justify without a clear use case.
Delphi connects people seeking advice with others who have relevant experience, and lets creators make digital versions of themselves available for questions. Topic browsing, featured expert chats and example questions give visitors ways to get started, but the published material does not establish answer quality or expert vetting.
The pricing page lists a free hosting plan and paid annual plans starting at $5,000 a year ($416.67 a month equivalent). Scaler lists 12M training words and 10 integrations; Scaler + API is $10,000 a year, with 20M training words and unlimited integrations. Monthly prices and seat limits are not published. The Reddit threads we read concern the Delphi programming language, so they offer no useful signal about Delphi.ai users.
Good fit if
- Creators sharing expertise through a digital version
- People seeking advice from relevant experience
- Teams scaling training and integrations
Skip it if
- Buyers requiring published monthly pricing
- Teams needing published seat limits
- Low-cost AI at organizational scale

01What Delphi actually does
Delphi is a platform for getting advice from people with relevant experience, and for letting experts or creators offer answers through a digital version of themselves. A user describes a situation and asks for perspective; the idea is to connect that question with people who have faced something similar.
You can browse topics such as career, startups, health, relationships, marketing and productivity, or ask featured experts about areas including management, business and personal growth. Delphi also surfaces example questions about everyday situations, from work priorities to family disagreements, and perspectives tied to personal, professional and practical challenges.
For creators and experts, the other side of the product is making a digital version that others can ask questions. The available plan details focus on hosting and training that version, rather than specifying limits for advice seekers. So Delphi is best understood as both an advice-discovery product and a way to make an expert’s knowledge available through an interactive digital persona.
02Where Delphi is strong
Delphi’s clearest strength is the specific advice-seeking flow: describe a situation and ask people with relevant life experience. That is more focused than browsing generic articles when the question is personal or depends on context. Topic browsing gives users a starting point across career, startups, health, relationships, marketing and productivity, while example questions can help someone turn a vague concern into a question they can actually ask.
The expert and digital-version features give the product a second use. Users can chat with featured experts on subjects such as management, business and personal growth; creators can build a digital version of themselves for others to question. For someone trying to make their expertise available beyond one-to-one conversations, that is the central pitch.
- Advice seekers can explore topics and practical scenarios rather than starting from a blank page.
- Experts and creators can host a digital version on Delphi’s platform.
- The Free Delphi plan costs $0 and includes platform hosting, according to the published plan details.
That makes the free plan the sensible first step. We would want to see whether the available people and answers fit a real use case before paying for expanded training or integrations.
03Where it falls short
The main drawback is the price jump from free to paid. The pricing page lists Scaler at $5,000 per year, equivalent to $416.67 per month, for 12 million training words and 10 integrations. Scaler + API is $10,000 per year, or $833.33 per month, for 20 million training words and unlimited integrations. Monthly billing prices are not published, so those monthly figures are annual costs divided across 12 months, not stated month-to-month rates.
The free plan hosts a Delphi, but its training-word and seat limits are not published. Seat limits are also not published for Scaler or Scaler + API, making it hard to estimate costs for a team. Immortal includes unlimited training words, but its price is tailored and its integration and seat limits are not published.
That leaves key buying questions unanswered: how much the free plan can handle, how many people can use paid plans, and what a tailored plan will cost. Try the free plan first; the $5,000 annual starting price is hard to justify without a clear use case.
04Delphi pricing: what you'll actually pay
Delphi has a free plan for hosting a Delphi on the platform, but its training-word and seat limits are not published. The first paid tier, Scaler, is listed at $5,000 per year—equivalent to $416.67 a month—with 12M training words and 10 integrations. Monthly billing prices are not published.
Scaler + API costs $10,000 per year, or $833.33 a month on an equivalent basis. That doubles the annual bill for 8M more training words and unlimited integrations; the seat limit is still not published. The Immortal plan includes unlimited training words, but its price is tailored and its integration and seat limits are not published.
The pricing lists no add-ons. The main gotcha is that the monthly figures are annual-price equivalents, not published month-to-month rates. We’d try the free plan first and confirm the required training capacity, integrations, and seat count before committing to at least $5,000 a year.
05Switching to (or from) Delphi
The published product and pricing details do not explain how to import an existing digital version, export training materials, or migrate conversation history. We’d get those answers from Delphi before building a setup you may later need to move. Also confirm whether your required integrations fit the 10-integration Scaler limit or require Scaler + API, which is listed at $10,000 a year.
For a move to Delphi, first identify what you want the digital version to answer and check whether the free plan’s unpublished training-word limit is enough to evaluate it. For a move away, ask what content and data you can take with you, in what format, and whether integrations can be disconnected without losing access to your materials.
We don’t have a sourced Reddit report on why Delphi users leave, so we won’t attribute a common reason to them. The clearest documented friction points are the $5,000 annual starting price and unpublished seat limits, monthly billing, and some plan caps. Get those details in writing before switching.
From the threadsWhat users say
The Reddit posts are about Delphi the programming language and development tools, not Delphi.ai, so they are not direct reviews of this advice platform. Those users show interest in Delphi for native Windows development, but one long-time user says they are quitting over a Community Edition limitation on publishing iOS apps.
Every 5-10 years or so, I had to re-invent myself to stay current
I'm curious where everyone is using Delphi and whether it is all for work, personal projects, or a mix of both
What I want is a RAD tool reminiscent of VB6 ( easy to use, non-bloated, creates native EXE, compiled programs run noticeably fast)
the CE version can't build and push iOS apps to app store anymore (and no one seems to care)
