Fluently
Fluently is an AI language tutor for professionals working in a second language. Sessions run like a phone call on iPhone, Android or the web, with no button to hold and instant feedback on pronunciation, fluency, vocabulary and grammar.
What is Fluently?
Fluently is published by Fluently Inc., a company registered in Delaware at 300 Delaware Ave, Wilmington, and operating out of San Francisco. It was founded in 2023 by Yurii Rebryk (CEO) and Stanislav Beliaev (CTO), and went through Y Combinator's Winter 2024 batch. The product is a mobile and web application for practising a language out loud with an AI tutor. Its store name has shifted from Fluently AI English Tutor to Fluently: AI Language Learning. The mechanic is a continuous voice conversation: there is no button to hold down, and reviewers describe a session as feeling just like a phone call. The tutor has a first name, Stacy in several reviews, and remembers earlier conversations from one session to the next. Speech is assessed on four axes: pronunciation, fluency, vocabulary and grammar. Around that sit several training modes, from games to structured courses organised by goal and level, and simulations of interviews and workplace situations. The technology is documented rather than merely asserted. In August 2026 Fluently published a benchmark, FLUENTLY-BENCH-01, on perceived-phone recognition in second-language speech, covering five model families and two evaluation sets. Its in-house model reaches a 20.97% phone error rate on real learner-tutor conversations, against 32.11% for the same method trained only on L2-ARCTIC. The proprietary FLUENTLY dataset holds 3.8 hours of training audio labelled by more than 400 linguists across 16 accents, with 0.6 hours held out for testing. On scale, the publisher claims learners in more than 160 countries, 999,000+ on the home page, 500,000+ Google Play downloads, and 4.8/5 ratings from roughly 5,400 App Store and 40,500 Google Play reviews. A newer Fluently for Teams tier adds a level per employee, structured practice, tracking and proof of progress. Two limits of scope are worth knowing. The privacy policy still describes a calendar connection with Google Calendar and Outlook and the analysis of online meeting recordings, a legacy of the original coaching-on-your-real-calls positioning. And on Apple's side the app is iPhone-only, 137 MB, iOS 16.4 minimum, listed under Education.

When to use Fluently / When not to
A quick filter to help you decide if Fluently is the right fit.
When to use Fluently
- Non-native English speakers who have to present, negotiate, run standups or answer hard questions in English at work
- Candidates rehearsing job interviews for their own role and industry before the real thing
- B1 to C1 learners who read and write competently but freeze the moment they have to speak
- HR and L&D teams that need a measurable speaking level per employee, with tracking and reporting
- Learners who want to practise out loud without being judged, at any hour, straight from their phone
When not to use Fluently
- Anyone under 18: the terms of service require users to be of legal age, whatever the App Store 4+ and PEGI 3 ratings suggest
- Learners looking for written grammar drills or flashcards: Fluently is built as the opposite, and says so with 'No taps. No flashcards.'
- Developers who want an API or an integration: no endpoint and no developer documentation are published
- Anyone unwilling to let their voice recordings train models: that is the default setting, and switching it off is a manual step
- Buyers who need a signed DPA or a published sub-processor list before deploying a tool: neither exists
How to use Fluently
A typical end-to-end flow, from setup to results.
- Choose your entry point: the App Store, Google Play, or the web app at app.getfluently.app; a single link, fluently.onelink.me, routes to the right store
- Open the web app and you land on an onboarding path at /onboarding/intro, which comes before any use of the product
- Sign in with an email account; the app asks for access to basic account information
- Pick the language you want to practise
- Start a conversation with the tutor and simply speak: there is no button to hold
- Receive corrections in real time and a personalised plan built from the session
- Optionally connect Google Calendar or Microsoft Outlook to see upcoming meetings inside the app
- Set your model-training and data-sharing preferences in account settings if you do not want your recordings used for training
- Manage the subscription where you bought it: App Store, Google Play or Stripe
- For a team, book a demo at app.getfluently.app/business, then follow the announced three-step sequence: pilot, report, decision on the data
Pros & Cons
Pros
- 4.8/5 on both stores, on serious volumes: roughly 5,400 App Store reviews and 40,500 on Google Play
- Real traction, with 500,000+ Google Play downloads and 999,000+ learners claimed on the home page
- Hands-free conversation with no button to hold, the point that comes back most often in user reviews

- Available on iOS, Android and in the browser, so practice follows you across devices
- 30-day money-back guarantee on purchases made directly on the site
- A documented way to switch off the use of your recordings for training, plus an enterprise tier with reporting, seat management and dedicated support
Cons
- No pricing page on the site: prices are only readable on the store listings and in a comparison table
- Inconsistent App Store grid, with two annual prices (USD 89.99 and USD 179.99) and two weekly prices (USD 6.99 and USD 9.99) coexisting
- A very broad licence over your recordings, and an explicit right to sell the de-identified data derived from them
- No DPA published or offered, no sub-processor list and no EU representative under Article 27, although the service explicitly addresses EEA and UK residents
- No API and no developer documentation, so nothing can be automated or embedded
- iPhone only on Apple's side, with no iPad or Mac version and iOS 16.4 as a minimum
- No contact or about page, no stated retention period, and no security certification such as SOC 2 or ISO claimed
Pricing & Plans
No permanent free plan is documented by the publisher. Both applications are free to download and monetised through in-app purchases. The lowest price point advertised by Fluently itself is USD 20.00 per month, taken from the comparison table on the /for-teams page, where it is set against USD 240 for a human tutor; the site publishes no pricing page. The in-app purchase tiers observed on the US App Store on 23 August 2026 tell a different story: weekly plans at USD 6.99 and USD 9.99, a monthly plan at USD 24.99, three-month plans at USD 44.99 and USD 89.99, annual plans at USD 89.99 and USD 179.99, and a one-off Workplace English course at USD 19.99. No single figure should therefore be read as an official price. Enterprise pricing is not public and requires a demo. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period.

Data, GDPR & hosting
A consolidated view of how Fluently handles your data.
GDPR overview
The privacy policy of 22 July 2026 carries a dedicated 'GDPR notice for residents in the EEA or UK'; the terms date from 25 June 2026. Four legal bases are invoked: consent, performance of the contract, legitimate interest and legal obligation. The rights listed are access, rectification, erasure, portability, restriction, objection including to profiling, objection to direct marketing, withdrawal of consent, and complaint to a supervisory authority. Transfers outside the EEA and UK, including between group entities, rely on the European Commission's standard contractual clauses; the destinations named, the United States and the Cayman Islands, are stated as carrying no adequacy decision. Rights are exercised through the in-app chat at app.getfluently.app/support or by phone on +1 (628) 200-4207, with support@getfluently.app reserved for CCPA requests. Two gaps: no Article 27 EU representative is designated and no data protection officer is named.
Who owns the data?
Fluently Inc. is the controller. The terms of service of 25 June 2026 have you grant Fluently a worldwide, royalty-free, perpetual, irrevocable, sub-licensable and transferable licence over your recordings, transcripts and related data, covering use, reproduction, storage, modification and derivative works. Fluently separately claims copyright over the material inside its services. The privacy policy of 22 July 2026 goes further: once data is de-identified it stops being personal information, and Fluently may use, retain, license or sell it for any business purpose. Fluently states it does not sell identifying personal information, and account settings allow opting out of aggregated data sharing. Card details are not stored by Fluently.
Reuse rights
Fluently collects sign-up details (name, email, phone, identifiers, IP address), professional data (company, job title, role, team), calendar metadata, billing data, audio and video recordings, technical and usage data, and data drawn from connected third-party tools. It uses them to deliver the service, provide support, analyse and improve the product, run marketing and advertising, and meet legal obligations. Recordings, transcripts and related data also feed model development: Fluently trains its own self-hosted speech-recognition, accent and pronunciation models on them, alongside models supplied by third-party AI services. Two exceptions are stated. Google Calendar data is never used to train any model, under Google's Limited Use rules, and Fluently says it does not retain the audio or video of other participants in a recorded meeting. Human access to recordings is restricted to named cases: a breach of the terms, a support request, a legal obligation, or the protection of rights. Advertising relies on third-party vendors including Google, and Google Analytics measures audience. Model-training and data-sharing preferences can be changed by the user in account settings.
Data retention & training
Hosting summary
Fluently operates from the United States, and the privacy policy of 22 July 2026 states that personal data may be transferred to, and accessed on, servers in the United States. Two transfer destinations are named, the United States and the Cayman Islands, and the policy states that neither benefits from a European Commission adequacy decision. Transfers outside the EEA and the UK, including between entities of the same group, are framed by the Commission's standard contractual clauses. No European hosting country is offered and no choice of hosting region exists. On security, Fluently declares physical, electronic and procedural safeguards and says it regularly runs security reviews, vulnerability scans and penetration tests. The Google Play Data safety card states that data is encrypted in transit and that deletion can be requested. What is left unsaid matters as much: no sub-processor is named beyond Google, for its APIs and Analytics, no sub-processor list is published, and no security certification such as SOC 2 or ISO 27001 is claimed.
Things to keep in mind
Risks and trade-offs to weigh before adopting Fluently.
- The licence you grant over your recordings and transcripts is perpetual, irrevocable, sub-licensable and transferable: it cannot be taken back later
- De-identified data stops being personal information and may be used, retained, licensed or sold for any business purpose, with no stated retention period and named transfers to the United States and the Cayman Islands
- Model training is on by default: turning it off is a manual step in account settings that most users will never take
- Judgement-free practice with a tutor that has a first name and remembers past sessions can become a comfortable substitute for the real conversations it is meant to prepare you for
- The terms require 18 or over, while the store ratings of 4+ and PEGI 3 let minors download the app and speak into it
- Mandatory individual arbitration and a waiver of class actions, with an opt-out to send within 30 days, under California law and before San Francisco courts
- Prices are not published on the site, store tiers are inconsistent between plans, and subscriptions renew automatically unless cancelled at least 24 hours before the period ends
Setup & Integrations
Technical difficulty
Very low. There is nothing to install beyond a store download, and nothing at all if you use the web app. You sign up with an email account and follow a guided onboarding path. Connecting Google Calendar or Outlook is optional and takes a few clicks. No server configuration, no API key and no development work are involved. On the team side, seats and billing are managed from a console and a pilot deployment is offered. The only hardware constraint comes from Apple: iPhone only, iOS 16.4 or later, 137 MB.

Should you pick Fluently?
Fluently is a more mature product than its Y Combinator Winter 2024 vintage suggests: two app stores, 4.8/5 on both, five-figure review counts and a claimed base approaching a million learners. Its differentiation is real and, unusually, documented: the publisher released a benchmark on perceived-phone recognition in second-language speech and reports its own error rates instead of adjectives. It answers a narrow, well-identified need: professionals who read and write a second language competently but stall the moment they have to speak it. Continuous voice conversation with no button to press, four scored axes, structured courses and interview simulation make a credible rehearsal room, and the newer Fluently for Teams tier extends it to HR reporting. The grey areas are contractual and commercial, not functional. There is no pricing page: the USD 20 per month the site sets against a human tutor's USD 240 sits next to a USD 24.99 monthly App Store subscription and two different annual prices, with no explanation. The licence taken over your recordings is perpetual, irrevocable and transferable, and de-identified data may be sold for any business purpose. Model training runs by default and has to be switched off by hand. No DPA, no sub-processor list, no Article 27 representative and no retention period are published, even though the privacy policy addresses EEA and UK residents directly. The shift from AI English Tutor to AI Language Learning widens the promise without the publisher documenting anywhere which languages can actually be practised. The enterprise tier is recent and carries no public price. Guidaio does not hand out scores: an individual buyer should check the exact price on their own store, and an organisation should ask whether it can deploy with no DPA and with model training on by default.
