Overview

What is Voilà?

Voilà is a general-purpose AI assistant published by Useful collective s.r.o., a Czech company based in Prague, and online since early 2023. Its central idea is that you should not have to change tools: Voilà opens on top of the site or application you are already working in and reads the context of the page, instead of asking you to copy your work into a separate chat window.

It runs on several surfaces. There is a browser extension for Chrome, Edge, Firefox, Brave and Safari, a desktop application for Windows and macOS still labelled a Preview release, a mobile progressive web app added to the home screen rather than installed from a store, and a plain web app that needs nothing installed. In the browser, typing 'voila' followed by a space or a tab in the address bar opens the assistant directly.

The engine is OpenAI. GPT-5.6 has been the default since 12 July 2026, after a documented succession of GPT-4o (May 2024), GPT-4o mini (July 2024), GPT-4.1 (April 2025), GPT-5 (August 2025) and GPT-5.5 (May 2026). Beyond a fair-usage threshold of roughly 500,000 words per month, requests fall back to GPT-5 mini. Users who supply their own OpenRouter key also reach Claude 3.5 Sonnet, Claude 3 Haiku, o1-mini, o1-preview and Gemini Pro.

Around the model sits a library of expert prompts covering 26 named deliverables, from ad campaigns and landing page copy to project charters, release notes and market research reports. Custom actions let you save a prompt, target part of a page with a CSS selector and pick a model and an output language per action, while Personas apply a reusable personality globally. Voilà also chats with documents and spreadsheets in eleven file formats, chats with images, generates images from text, summarizes and transcribes YouTube videos, and runs Deep Search with links to its sources. Conversation history can be searched, renamed, exported, favourited and shared by link, and Voilà Automate fires webhooks from a custom action to Zapier, Make.com or a custom endpoint. A team offer adds shared libraries, shared workflows and a pooled request allowance. The site claims more than 100,000 users and a 4.9 rating from over 250 reviews republished from AppSumo.

Audience

When to use Voilà / When not to

A quick filter to help you decide if Voilà is the right fit.

When to use Voilà

  • Knowledge workers who read, write and research in the browser all day and would rather call an assistant onto the current page than switch tabs.
  • Marketing and content professionals, who get an expert prompt library covering ad campaigns, landing page copy, blog posts, SEO content, social posts and product descriptions.
  • People who live in their inbox: Voilà drafts and answers emails, stores reusable templates and offers a one-click Instant Reply.
  • Teams that need a shared prompt library, shared workflows and templates, a pooled request allowance and centralised member and billing management.
  • Cost-conscious users: the free tier asks for no credit card, and anyone who already holds an OpenAI API key can take the Bring Your Own Key plan at 5 USD per month.

When not to use Voilà

  • Regulated organisations that require a signed DPA and a security certification before onboarding a vendor: no DPA is published or offered on request, and no SOC 2 or ISO 27001 evidence is displayed, only 'GDPR Compliant' and 'CCPA Ready' claims.
  • Privacy and compliance teams that must document data residency, since no hosting country or region is named in the privacy policy, the terms of use or the teams page.
  • Developers who want to build on the tool: there is no public API and no developer documentation. The webhooks let Voilà call external services, not the reverse.
  • Anyone processing large or scanned document sets: document chat accepts a maximum of three attachments of 2.5 MB each and has no OCR, so scanned PDFs do not work.
  • Users who expect Claude or Gemini natively, a native Android app or a settled desktop build: other model families require a personal OpenRouter key, mobile is a progressive web app, and the desktop app is still a Preview release.
Get started

How to use Voilà

A typical end-to-end flow, from setup to results.

  1. Create a free account on the sign-up page: no credit card is required.
  2. Install the browser extension for Chrome, Edge, Firefox or Brave from the download page.
  3. On desktop, install the Windows (.exe) or macOS (.dmg) build hosted on the publisher's GitHub releases; Safari users are directed to that same desktop app.
  4. On mobile, open the install link or scan the QR code from the app page, then add the progressive web app to your home screen.
  5. Or skip installation altogether and use the Voilà web chat in any browser.
  6. Open Voilà on any page, or type 'voila' followed by a space in the browser address bar.
  7. Pick an action from the prompt library or type a free-form request; the up arrow recalls recent prompts and the space bar triggers follow-up actions.
  8. Use the content of the current page as context, or attach a document or an image by drag and drop, by pasting it, or through the paperclip icon.
  9. Set the answer language with the 'Output language' button at the bottom right.
  10. Go further with custom actions built on a CSS selector or a webhook URL, Quick Actions on selected text in the desktop app, and team invitations from the team details page.

Pros & Cons

Pros

  • Works on top of any website and any application, so there is no tool to switch to and the assistant sees the context of the page
  • Unusually wide surface coverage for the price: extensions for five browsers, Windows and macOS desktop apps, a mobile progressive web app and a web chat
  • Explicit commitment that content and AI conversations are neither stored on the publisher's servers nor used to train the AI
  • Subprocessors are named in the privacy policy (OpenAI, Microsoft Azure, Paddle, Google Analytics, PostHog), and the publisher is established in the European Union with a named supervisory authority
  • A genuine free tier with no credit card, a 20% discount on annual billing for Premium and Ultimate, and a Bring Your Own Key plan at 5 USD per month carrying the Ultimate feature set
  • Open automation through webhooks to Zapier, Make.com or a custom endpoint, which is uncommon in an assistant extension
  • A supplied prompt library, custom actions and Personas, plus around 50 free AI tools usable without an account

Cons

  • Default dependence on OpenAI: reaching Claude, Gemini or o1 requires a personal OpenRouter key
  • No DPA published, no hosting location declared and no transfer mechanism described, although the AI subprocessors are US companies; no security certification is displayed either
  • No public API and no developer documentation
  • Legal documents lag the product: the terms of use are dated 28 February 2023, the privacy policy carries no effective date, and there is no contact page or legal notice, everything going through a single email address
  • Tight upload limits (three attachments, 2.5 MB per file, no OCR) and an automatic fallback to GPT-5 mini beyond the fair-usage threshold
  • Refunds only on a written request within 24 hours, purchases being final otherwise, with liability capped at the higher of twelve months of subscription fees or 100 USD
  • The desktop app is still a Preview release, there is no native Android or iOS app, and the free tier advertises 250 requests without stating over what period

Trust & Privacy

Data, GDPR & hosting

A consolidated view of how Voilà handles your data.

GDPR overview

Voilà displays 'GDPR Compliant' and 'CCPA Ready' badges on its home page and repeats the claim on its teams page. The privacy policy names Useful collective s.r.o. as controller, contactable at hello@getvoila.ai, and sets out rights of access, rectification, portability, erasure, objection and restriction of processing, plus an unsubscribe route against direct marketing. The Czech supervisory authority is named: the Úřad pro ochranu osobních údajů, Pplk. Sochora 27, 170 00 Prague 7. Subprocessors are disclosed: OpenAI, Microsoft Azure, Paddle, Google Analytics and PostHog. No Article 27 representative is designated, which is consistent with an establishment inside the European Union, and no data protection officer is appointed. Three gaps remain: no published DPA, no declared hosting country or region, and no described transfer mechanism such as standard contractual clauses, although the AI subprocessors are US-based.

Who owns the data?

The terms of use claim all intellectual property rights in the Services themselves, including text, graphics, logos and trademarks, for the publisher Useful collective s.r.o. or its licensors. Neither the terms nor the privacy policy contains any clause assigning ownership of the content users submit or of the AI output they receive: the question is simply not addressed, which is a fact to note rather than a guarantee in the user's favour. The publisher states that content and AI conversations are never stored on its servers. Requests are processed through the OpenAI API and Microsoft Azure, whose own terms govern that processing.

Reuse rights

Creating an account collects an email address, a hashed password, a location and an IP address; contacting support adds a full name, an email address, a location, a device type and an operating system. The stated purpose is to perform and execute the service and to personalise the experience, on the legal bases of performing the terms, meeting legal obligations and revocable consent. Data may be shared with regulators and authorities under a validated request, transferred in a merger, acquisition or bankruptcy, and passed to third parties with the user's consent. Payments run through Paddle and are not stored or processed on the publisher's servers; Google Analytics and PostHog record visit frequency, page views and referring site, while cookies and anonymous identifiers support personalisation. User content is never used to train the AI. As for the outputs, the documents place no restriction on what users do with what they generate, but they grant no explicit reuse licence either: the point is left unaddressed.

Data retention & training

Retention summary
The privacy policy states a single retention rule: data is kept until it is no longer necessary to provide the service, or until the account is deleted, whichever comes first. Account deletion is available on request by contacting the publisher. No figures accompany that rule, with no retention period, no purge deadline and no backup policy documented. The publisher also states that user content and AI conversations are not stored on its servers at all, so the rule applies in practice to account and support data such as the email address, hashed password, location and IP address. Payment data is held by Paddle rather than by the publisher. Nothing is said about anonymisation, or about how long the analytics data collected through Google Analytics and PostHog is kept.

Hosting summary

The publisher names no hosting country and no hosting region anywhere in its privacy policy, its terms of use or its teams page: there is no data residency statement to report. What it does state is that user content and AI conversations are not stored on its servers, that sensitive information is encrypted in transit over SSL, that access is limited and networks are secured, and that vulnerability scans are run regularly. The account data that is kept, namely email address, hashed password, location and IP address, sits with a controller established in Prague, Useful collective s.r.o., which places the controller under Czech and European Union jurisdiction even though the location of the servers is not disclosed. The disclosed subprocessors handling data are OpenAI, Microsoft Azure, Paddle, Google Analytics and PostHog. Separately, and not as a publisher declaration, a network probe run on 24 August 2026 showed the domain resolving to 15.197.246.237, an Amazon.com (AS16509) anycast node geolocated in Seattle, United States. That reflects the website infrastructure only and says nothing certain about where user data is processed or stored.

Watch-outs

Things to keep in mind

Risks and trade-offs to weigh before adopting Voilà.

  • Convenience can turn into dependence: an assistant available on every page makes it easy to stop drafting, summarising and checking things yourself, and skills that go unused tend to fade.
  • Outputs come with the fluency of a language model but not its certainty. Deep Search cites its sources precisely because answers still have to be verified before they are used or published.
  • No DPA is published and no hosting country or region is declared, while the AI subprocessors (OpenAI, Microsoft Azure) are American and no transfer mechanism outside the European Union is described: a real question for confidential or personal data pasted into the assistant.
  • The legal documents are old relative to the product. The terms of use are dated 28 February 2023, the privacy policy carries no effective date, and the two texts disagree on age, the terms requiring 18 years while the privacy policy sets a floor at 13.
  • Commercial terms are strict: purchases are final apart from a written refund request within 24 hours, and liability is capped at the higher of twelve months of subscription fees or 100 USD.
  • Service continuity is not guaranteed. The publisher may suspend, restrict or change a plan in case of use it considers disproportionate, may terminate at its sole discretion without notice, and provides the service as is, without warranty of continuity or accuracy.
  • Quotas and support are easy to misjudge: fair usage is about 500,000 words per month before a fallback to GPT-5 mini, the free tier states 250 requests without naming a period, the desktop app is still a Preview release, and a single email address serves support, GDPR and legal questions.
Setup

Setup & Integrations

Technical difficulty

Everyday use requires no technical skill: create a free account without a credit card, then install the extension in a few clicks. The desktop app uses a standard Windows (.exe) or macOS (.dmg) installer, and mobile is a progressive web app added to the home screen with no app store involved; the web chat needs no installation. Only two features are advanced: custom actions built on a CSS selector, and webhook automation, defining the expected JSON object and running the action once so the endpoint learns the format. Bring Your Own Key assumes you can obtain an API key.

FAQ

Frequently asked questions

Where can I use Voilà?
On four kinds of surface: a browser extension for Chrome, Edge, Firefox, Brave and Safari, a desktop application for Windows and macOS, a mobile progressive web app added to the home screen, and a web app that runs in any browser without installation.
Which AI models power Voilà?
OpenAI models. GPT-5.6 has been the default since 12 July 2026, with an automatic fallback to GPT-5 mini beyond the fair-usage threshold. Claude, Gemini and o1 models can be reached by supplying a personal OpenRouter key.
Is there a free plan?
Yes. The Free plan costs nothing, requires no credit card and includes 250 free requests. It is a permanent free tier rather than a time-limited trial.
How much do the paid plans cost?
Premium is 10 USD per month, or 8 USD per month billed annually. Ultimate is 20 USD per month, or 16 USD per month billed annually. Bring Your Own Key is 5 USD per month with your own OpenAI API key, and Teams starts at 16 USD per seat per month.
Are my conversations stored or used to train the AI?
The publisher states that content and AI conversations are never stored on its servers and are never used to train the AI. That is a declaration by the publisher, repeated on the home page, the help FAQ and the teams page; no independent attestation is published.
Who processes my requests?
Requests are processed through the OpenAI API and Microsoft Azure. The privacy policy also discloses Paddle for payments and Google Analytics and PostHog for analytics.
Which file types can I chat with?
The supported formats are .pdf, .docx, .xls, .xlsx, .csv, .xml, .json, .yaml, .yml, .txt, .md and .html. Uploads are capped at three attachments of 2.5 MB each, and there is no OCR, so PDFs made of scanned images will not work.
Can I automate tasks, and is there a Voilà API?
Automation is possible through webhooks fired from a custom action towards Zapier, Make.com or your own endpoint. There is, however, no public Voilà API and no developer documentation: the webhooks call external services, they do not expose Voilà itself.
Is Voilà available worldwide and in my language?
The site's FAQ states that Voilà is available worldwide. Answers are returned in the language of the input by default, and the output language and dialect can be set explicitly, for example Spanish, UK English or Canadian French.
Who publishes Voilà, and is there a minimum age?
Voilà is published by Useful collective s.r.o., Tusarova 1179/37, 170 00 Prague, Czech Republic, reachable at hello@getvoila.ai. The terms of use require users to be at least 18 years old, or to have the permission and supervision of a parent or legal guardian.
Conclusion

Should you pick Voilà?

Voilà's positioning is clear: rather than asking you to come to the assistant, it comes to you, opening on top of whatever site or application you are already using and reading the context of the page. That principle is carried across an uncommon range of surfaces for the price — extensions for five browsers, Windows and macOS desktop builds, a mobile progressive web app and a web chat — and it is backed by a prompt library, custom actions, Personas and webhook automation.

Value for money is favourable, particularly on the Bring Your Own Key plan, which delivers the Ultimate feature set for 5 USD per month to anyone who already holds an OpenAI API key. The privacy stance is stated plainly and repeated on the home page, the help FAQ and the teams page: content and conversations are neither stored on the publisher's servers nor used for training, and the subprocessors are named.

The weak point is paperwork rather than product. No DPA is published, no hosting country or region is declared, no transfer mechanism is described although the AI subprocessors are American, and no security certification is shown. The terms of use date from February 2023 and the privacy policy carries no effective date, so the legal layer describes a product several years of changelog behind the current one. The publisher is a small Czech company with two partners, which explains the light legal apparatus without answering the question for a corporate buyer.

The product itself is clearly maintained: the changelog is active and GPT-5.6 was integrated in July 2026. For an individual or a small team, Voilà is a solid, well-priced everyday assistant; a regulated organisation will need to ask for the compliance documents before adopting it.
