Fluents
Fluents is an AI voice operations platform that answers inbound calls and runs paced outbound campaigns on your own contact lists, bundling agents, telephony, campaign controls and 214 integrations into a single dashboard.
What is Fluents?
Fluents is an AI voice operations platform built for teams whose phones already ring more than their headcount can answer. It covers two motions in one product: inbound, where agents answer, resolve, transact and route, and outbound, where paced campaigns run on contacts a company already owns, loaded from CSV or synced from a CRM.
Four building blocks live in the same dashboard. Agents carry the conversation, with voice, prompts, skills and mid-call actions configured per use case. Telephony is native: buy numbers from Fluents or bring your own trunk, then manage number reputation and verified business caller ID. Campaign controls cover pacing, contact windows, schedules, retries, answering-machine detection and do-not-call handling. Integrations write the outcome back where operators already work, with 214 connectors claimed and Salesforce, HubSpot, Zendesk, Google Calendar, Calendly, Zapier and Shopify among those named.
The order-status example on the homepage shows the whole loop: a caller asks where an order is, intent is detected, Fluents queries the Shopify API and the carrier, reads the tracking aloud and closes the Salesforce ticket, with nobody in the path. When a person is genuinely needed, the platform warm-transfers with full context instead of dropping the caller into a queue.
Conversation quality is a stated focus: natural turn-taking through interruptions and pauses, studio-grade voice cloning so the agent sounds like the brand, and multilingual delivery with code-switching. After hang-up, transcripts, recordings and dispositions feed call insights that surface drivers, drop-offs and handoff reasons, closing an explicit review, tune, redeploy and measure loop.
Builders get a real surface rather than an afterthought: REST resources under /v1, a full OpenAPI specification, webhooks on connect, disconnect, transcription and outcomes, branching on live variables mid-call, and the option to bring your own LLM, TTS or STT. Separate environments and keys, RBAC, request logs and audit trails come with it.
Published by Fluents.ai, Inc. of Mill Valley, California and founded in October 2024, the company claims hundreds of thousands of calls a day and a first workflow in production in about a week.

When to use Fluents / When not to
A quick filter to help you decide if Fluents is the right fit.
When to use Fluents
- Support and operations teams whose inbound lines saturate during peaks and seasonal spikes
- Ecommerce teams handling phone orders and order-status calls that need Shopify and carrier lookups mid-call
- Insurance and financial services teams running renewals, claims-status and confirmation programs on books they already own
- Agencies running paced outbound programs on client-approved lists and needing reporting they can share
- Practices and front desks in healthcare, real estate and home services that lose bookings to unanswered phones
When not to use Fluents
- Anyone needing to pass financial, medical or sensitive personal data through the calls: the terms of service prohibit it outright
- Teams without an existing contact list or systems to connect, since Fluents runs the phone layer but does not supply the contacts
- Solo users and side projects: there is no permanent free plan, and the entry tier bills 49 US dollars a month for only 120 minutes
- Buyers who need documented data residency, a published subprocessor list or a security certification such as SOC 2 before signing
- Teams wanting a mobile app, as Fluents ships only as a web dashboard and an API with no iOS or Android release
How to use Fluents
A typical end-to-end flow, from setup to results.
- Start the 14-day free trial from the Fluents platform, which asks for no credit card
- Configure your agent: choose a voice, write the prompts, and enable the skills that resolve, book, route or call your systems
- Connect your systems of record, from CRM and ecommerce to calendars and help desks, through OAuth and field mapping without writing code
- Wire niche or proprietary systems through webhooks, the REST API and mid-call actions, scoped with the Fluents team
- Buy phone numbers from Fluents or bring your own trunk, then set up verified business caller ID
- Load your contacts by CSV upload or sync them straight from your CRM
- For outbound work, set contact windows, pacing, retries, answering-machine detection and do-not-call rules before launching
- Point your inbound lines at Fluents and let the agents answer, resolve and route
- Add SMS or email follow-ups wherever the workflow needs a written confirmation or next step
- Review transcripts, dispositions and call insights, tune the agent or the campaign, then measure the next run
Pros & Cons
Pros
- Pricing is genuinely published: four tiers with their minute pools, concurrency limits, number counts and overage rates all on the page
- Unlimited agents, users and workflows on every paid plan, with API access and reporting included from the cheapest tier upward
- Inbound resolution and outbound campaigns run on one platform instead of two separate tools
- Campaign machinery such as pacing, answering-machine detection, do-not-call and contact windows ships in the product rather than being left to the buyer
- Operators run it from a dashboard and the API is there when needed, without being mandatory
- The terms of service leave you owning both your inputs and your outputs
- Portability is real: bring your own telephony trunk and your own LLM, TTS or STT
Cons
- No permanent free plan, only a 14-day trial, after which the floor is 49 US dollars a month
- The entry tier buys just 120 minutes, 5 concurrent calls and 2 numbers, with overage at 0.45 US dollars a minute, over four times the Scale rate
- No hosting country or region is published anywhere, so EU data residency cannot be verified
- No subprocessor list is published, although the privacy policy refers to third-party AI services
- No documented way to exclude your data from model training, and no stated position on training from customer content outside the Google Workspace carve-out
- No security certification is published, neither SOC 2 nor ISO 27001, with only a PCI-compliant claim on phone order taking
- SSO and SAML, audit logs, formal SLAs, a BAA or DPA and dedicated or self-hosted deployment are Enterprise-only, at an undisclosed price

Data, GDPR & hosting
A consolidated view of how Fluents handles your data.
GDPR overview
Fluents never claims GDPR compliance in so many words, but the privacy policy of 21 April 2025 carries most of the substance. A dedicated Europe section covers the EEA, Switzerland and the United Kingdom, names the legal bases relied on, consent, performance of a contract, legitimate interest and legal obligation, and confirms that transfers to third parties are safeguarded by European Commission-approved standard contractual clauses, with further measures where appropriate. The rights listed are complete: access, correction, updating, erasure, objection, restriction, portability, withdrawal of consent and complaint to a supervisory authority, all exercised through support@fluents.ai. A DPA is available, cited alongside a BAA among the Enterprise commitments. Two gaps stand out: no Article 27 EU representative is named and no data protection officer is designated.
Who owns the data?
Under the terms of service you keep what you bring and what comes out: you retain ownership of your Input and own all Outputs created through the service, to the fullest extent the law allows. The platform itself is not yours. Trademarks, software, know-how and trade secrets stay with Fluents.ai, Inc. as what the terms call Fluents IP, and nothing grants you a licence over them. Ownership is also not exclusivity: Fluents may use your Content to provide, maintain, develop and improve the service, to comply with the law and to enforce its terms and policies, and it may refuse or act on any content at its sole discretion. You stay responsible for everything your users say through the service.
Reuse rights
You can reuse your own material without asking Fluents for anything. Because the terms grant you ownership of the Outputs, transcripts, recordings, summaries and call dispositions can be pushed into your CRM, your warehouse or your BI tools and used commercially, and the platform is built to do exactly that. The constraints sit on what you feed in rather than on what you do afterwards: you warrant that your content is lawful and infringes nobody's rights, and you may not transmit financial, medical or sensitive personal data through the service. Fluents runs a parallel licence over the same material, using it to operate and improve the platform and disclosing it to service providers, which the privacy policy says may include third-party AI services. Payment details are handled by Stripe. One carve-out is explicit and one-way: Google Workspace data is never used to develop, improve or train AI models and is not shared with third-party AI tools, unless you configure that sharing yourself.
Data retention & training
Hosting summary
Fluents publishes no hosting location. The privacy policy states only that information is processed at its operating offices and in any other places where the parties involved in the processing are located, and warns that data may be transferred to and held on computers outside the user's state, province or country, in jurisdictions whose data protection laws differ. The company undertakes to take reasonable steps and maintain adequate controls before any transfer. For individuals in the EEA, Switzerland and the United Kingdom, transfers to third parties are covered by European Commission-approved standard contractual clauses plus additional safeguards where appropriate. The publisher, Fluents.ai, Inc., is established in Mill Valley, California, and the terms are governed by California law with arbitration in San Francisco, so United States processing should be assumed by default. Note that the domain resolves to an anycast address on Amazon's network, which tells you where the marketing site is served, not where call recordings and transcripts are stored. Buyers with a data residency requirement should raise it before signing, because nothing on the site answers it.
Things to keep in mind
Risks and trade-offs to weigh before adopting Fluents.
- Callers are not necessarily told they are speaking to a machine: the site never mentions AI disclosure, and in several jurisdictions that duty falls on you, not on Fluents
- Outbound calling is legally loaded. Pacing, contact windows, answering-machine detection and do-not-call controls exist in the product, but consent and list hygiene remain your liability
- The terms forbid sending financial, medical or sensitive personal data through the service, yet the marketing courts insurance, healthcare and phone payments. A caller reciting a card number or a symptom puts you outside the contract
- Voice cloning that makes an agent sound like your brand is the same technology that makes impersonation convincing, so restrict who can create and deploy voices
- Nothing is published about where recordings and transcripts live, who processes them or how long they are kept, which makes a data subject request hard to answer with confidence
- Automating containment can quietly degrade service for the callers least able to navigate a machine, such as elderly people, people in distress or non-native speakers, and a dashboard measuring containment will not show it
- Overage at 0.45 US dollars a minute on the entry tier turns a misconfigured campaign into an invoice before anyone notices, and there is no refund once the month has been billed
Setup & Integrations
Technical difficulty
Low for the standard path. Mainstream CRMs, calendars and help desks connect through OAuth and field mapping in the dashboard, explicitly without a project team, and most teams get a first real workflow live in about a week. What you do need to master is campaign mechanics: pacing, contact windows, retries, answering-machine detection, do-not-call rules and caller ID, which are operational rather than technical skills. Difficulty rises with proprietary or niche systems, scoped with Fluents through webhooks and the REST API. Guided setup, onboarding help and direct access to the team, often through a shared Slack channel, are offered.

Should you pick Fluents?
Fluents makes a clear bet: rather than sell a voice-agent builder and leave the operational plumbing to the buyer, it ships telephony, campaign pacing, do-not-call handling and 214 connectors as part of the product. Against the alternatives it names itself, Vapi, Retell, Bland, Synthflow and Regal, that is the difference between a toolkit and something an operations team can actually run, and it explains the promise of a first workflow live in about a week.
The commercial side is unusually candid for the category. Four tiers, their minute pools, their concurrency limits and their overage rates all sit on the pricing page, and unlimited agents, users and workflows come with every one of them. Read the numbers carefully, though: at 49 US dollars a month Starter buys 120 minutes with overage at 0.45 a minute, so the real operational entry point is SMB at 299.
Where it thins out is governance. No hosting country or region is published, no subprocessor list exists, no security certification is claimed beyond PCI on order taking, and the vendor never says whether it trains models on customer content outside an explicit Google Workspace carve-out. For an insurance or healthcare buyer, verticals the site actively courts, those gaps matter, especially alongside terms that forbid transmitting financial or medical data through the service at all. Note too that the terms set a minimum age of 13 while the privacy policy asserts 18.
Founded in October 2024 with five people on its team page, Fluents is young, and its terms disclaim any guarantee of uptime or reliability outside a separate written agreement. For an operations team with real phone volume, existing lists and systems to connect, it is worth a trial. For a regulated buyer, take the compliance questions to a demo first.
