Prezo
Prezo is an AI workspace from Barrel Through Inc. that turns a brief, a résumé or a pile of files into presentations, documents and personal websites, then lets you question them and route the conversation across several leading models.
What is Prezo?
Prezo is an AI creation platform published by Barrel Through Inc., a Californian company. The title the site sets states the promise directly: create presentations, documents and websites with AI. A visitor who is not signed in meets an animated question — what will you create today? — followed by an invitation to select a use case to start. Two are offered. Personal site builds an online profile for personal branding and networking; it asks you to upload or paste a résumé or LinkedIn profile and lists the fields it expects, from name, location and role through to experience, projects and social links. General presentation is aimed at business and academic use: you describe the purpose of the deck and any relevant detail, then set language, tone and audience in the settings.
Behind those two doors sits a broader product the company calls an orb, presented as an AI smart folder for all your files. An orb pairs a knowledge base with a persona, keeps its memory between sessions and, according to the about page, grows more useful with every conversation. Orbs are collaborative and shareable by design, and the company points to project management, event coordination and community onboarding as the situations it suits, places where conventional tools feel rigid. Files arrive by drag and drop or by URL, are organised into folders, and can be shared by email, published behind a public link or opened through an invitation code. Conversation is not confined to the built-in assistant: the interface routes the same thread to Claude, OpenAI's GPT, Gemini, Grok, Llama, DeepSeek or Qwen.
Two things temper the picture. The domain is in transition, and a banner tells former customers that it has been migrated to the company's new AI platform while their old account lives elsewhere; the legal pages still describe the product under its other name. The application also carries an alpha version marker, signs users in with a one-time code sent by email, and meters consumption through purchasable credits it calls fuel, whose prices appear only once you hold an account.

Pros & Cons
Pros
- A first attempt costs nothing, thanks to a usage allowance for anonymous and unpaid accounts
- Two guided use cases remove the blank-page problem for newcomers
- Several leading models are reachable from a single interface, without separate subscriptions
- Files and conversation share one workspace, with memory that survives between sessions
- Data ownership is stated explicitly in both the terms and the privacy policy
- An opt-out from data being used for service improvement is written into the policy
- Nothing is locked in: individual resources and whole folders export as ZIP archives
Cons
- No pricing page at all, and credit pack prices become visible only once you hold an account
- The brand is mid-migration, and the legal pages still describe the product under another name
- No mention of GDPR, no data processing agreement, no EU representative and no retention period
- The hosting country and region are never disclosed
- An alpha version marker is displayed in the application, so scope and interface may still move
- English-only interface, with no mobile application, no public API and no contact page
- The voice features the about page presents as central are switched off on this domain
Pricing & Plans
Prezo publishes no pricing page and states no rates. Paid usage runs on prepaid credits, which the company calls fuel and sells in packs denominated in US dollars, with tax added at checkout; the endpoint that serves those packs requires an account, so the lowest paid entry point cannot be verified publicly. A free entry point does exist in practice: the application allocates a usage allowance to anonymous visitors and a larger one to registered accounts that have not paid, reserving the largest for paying users. No time-limited free trial is advertised.

Data, GDPR & hosting
A consolidated view of how Prezo handles your data.
GDPR overview
There is no GDPR implementation to report. Neither the privacy policy, the terms of use, the about page nor the application itself mentions the General Data Protection Regulation at any point: no lawful basis, no data protection officer, no Article 27 EU representative, no data processing agreement and no retention period. Barrel Through Inc. is a Californian company with no declared European entity or address. The policy, last updated in May 2025, does grant rights that overlap with GDPR ones — access to the data held, deletion on request, an opt-out from data being used for service improvement where applicable, and notice of significant changes — but it offers them as company commitments, not as regulatory compliance. European buyers with contractual obligations will find nothing here to rely on.
Who owns the data?
Both the terms of use and the privacy policy state plainly that the user keeps ownership of what they upload and create. Barrel Through Inc. positions itself as a custodian rather than an owner: it may access account details, audio input, transcripts and usage logs in order to run and improve the service, personalise responses, troubleshoot performance and monitor abuse. The processors it names — OpenAI and other model providers, Supabase for database storage and authentication, and unnamed infrastructure suppliers — are described as handling that data solely on the company's behalf and not for their own purposes. Users may ask what is held about them and request deletion at any time, which is granted unless a legal obligation requires retention.
Reuse rights
Because ownership stays with the user, nothing in the terms restricts reusing what goes in or comes out. Presentations, documents, personal sites and uploaded files remain yours to publish, print, sell or repurpose without asking permission, and no attribution requirement, watermark or restriction on commercial use is stated anywhere. The platform supports that in practice rather than merely tolerating it: individual resources and entire folders can be exported as ZIP archives, and results can be shared by email, opened behind a public link or handed over through an invitation code. The one reservation runs the other way, in the company's favour: the privacy policy keeps open the possibility of using anonymised data to improve model performance in future.
Data retention & training
Hosting summary
Prezo discloses nothing about where data is hosted. Neither the privacy policy, the terms of use nor any other page names a country, a region or a data centre, and no residency option is offered. What the policy does name is the processing chain: Supabase for database storage and user authentication, model APIs including OpenAI, and unnamed infrastructure providers, all described as acting on the company's behalf and not for their own purposes. The publisher, Barrel Through Inc., is established in California, which places the service under United States jurisdiction by default. Technical observation adds a little, though none of it is a company statement: the domain resolves to a Cloudflare anycast address registered in the United States, and the application's backend answers on a Render-hosted endpoint. None of this amounts to a hosting commitment. Anyone with data residency requirements should treat the location as unknown and ask directly before uploading anything sensitive.
Things to keep in mind
Risks and trade-offs to weigh before adopting Prezo.
- Ownership is asserted but not bounded: the policy keeps open the future use of anonymised data to improve model performance
- Voice recordings and session transcripts are collected, and no retention period is given for either
- Leaning on generated decks erodes the habit of structuring an argument yourself, a skill that is slow to rebuild
- A personal site assembled from a résumé repeats any error or exaggeration it contains, with the authority of a polished page
- Buying credits whose prices are not published makes it easy to lose track of what a working session actually costs
- Public links and invitation codes make oversharing effortless: a folder opened once stays open until it is revoked
- The alpha status and the ongoing domain migration mean work in progress could be disrupted or need moving
Setup & Integrations
Technical difficulty
Setup is minimal. Prezo runs entirely in a browser, with nothing to install, no API key to supply and no model configuration to choose. A first attempt is possible without an account, within the anonymous allowance; going further needs only an email address, confirmed by a one-time code. Material is added by dragging files in or pasting a URL, and the two guided use cases walk a newcomer through to a first result. The only friction likely to interrupt a session is running out of fuel credits, which calls for a purchase before work can continue.

Should you pick Prezo?
Prezo is a genuinely interesting idea caught at an awkward moment. The concept holds together: two guided doors — a personal site built from a résumé, a presentation shaped by language, tone and audience — opening onto a smart folder that keeps your files, remembers what has been said and lets you put the same question to Claude, GPT, Gemini and four other models without leaving the page. For a founder needing a portfolio, a student assembling a deck or a small team that wants its documents and its assistant in one place, that combination does real work.
What surrounds it is harder to recommend without reservation. The domain is mid-migration: a banner redirects former customers to another address, and the legal pages still describe the product under a different name and a different domain. The application shows an alpha version marker. More consequentially for anyone buying rather than trying, there is no pricing page whatsoever — credit packs are priced in US dollars but only once you have an account — and the legal disclosure is thin: no mention of GDPR, no data processing agreement, no EU representative, no retention period and no stated hosting location.
The company does better on the point that matters most. Ownership of your material is asserted clearly in both documents, deletion is available on request, an opt-out from service-improvement use is written down, the processors are named, and everything exports as a ZIP archive. Treat Prezo as a promising young tool worth trying on non-sensitive work, and ask about pricing, hosting and retention before committing anything that matters.
