Flowrite
Flowrite was an AI email writing tool, now acquired by Maestro Labs and folded into MailMaestro. Its domain redirects to a transition page, and former users are pointed to MailMaestro's assistant for Outlook and Gmail.
What is Flowrite?
Flowrite began as the AI email writing arm of Flow AI, and it no longer exists as a product you can buy. Maestro Labs, the company behind MailMaestro, acquired Flowrite and folded its business into MailMaestro; flowrite.com now lands on a transition page titled Flowrite is now MailMaestro. The original team stayed with Flow AI, which builds a platform for evaluating and improving LLM systems, a different business altogether. This entry therefore documents an archived brand and the service that took its place.
What a former Flowrite user finds today is MailMaestro, presented by its publisher as the number one independent AI email assistant. It ships as an Outlook add-in through the Microsoft Marketplace, as a Chrome extension for Gmail, and with a web dashboard at dashboard.maestrolabs.com. The feature set covers the ground Flowrite used to: an AI email writer that turns a short instruction into three drafts with a choice of language, tone and length; AI responses built from a thread and its attachments; automatic thread and attachment summaries at an adjustable length; and inbox management with triage, priority labels and reminders. Magic Templates and keyword shortcuts handle repetitive correspondence. The drafting runs on advanced language models from OpenAI and Anthropic, with GPT-4o and Claude 3.5 named on the free plan.
Around it sits a wider Maestro Labs suite: TeamsMaestro for meeting notes, CalMaestro for scheduling, WordMaestro for Microsoft Word. The publisher claims 300,000+ teams on its homepage, though the pricing page still says 55,000+, and store ratings run high, at 4.8 on Outlook across 936 reviews and 4.9 on Gmail across 164.
The compliance posture is unusually thorough for the price point: SOC 2 Type II, GDPR, HIPAA with a BAA on request, CASA Tier 2, plus Microsoft and Google attestations. Data is encrypted in transit and at rest, never used to train AI models, and enterprise customers can ask for zero-day retention and PII obfuscation. The publisher is Maestro Labs Pte. Ltd., headquartered in Singapore, with databases in the United States and the European Union.

Pros & Cons
Pros

- Runs inside Outlook and Gmail with nothing to install locally

- An explicit commitment that customer data is never used to train AI models
- Zero-day retention and PII obfuscation available to enterprise customers
- 20+ languages for drafting and summarising, on models from OpenAI and Anthropic
Cons
- Flowrite itself is gone: any continuity means a different product, a different publisher and a different jurisdiction
- The free plan is very tight, at three AI requests per week shared across composing, replying and improving
- The USD 12 headline price requires a non-refundable annual commitment; month to month costs USD 15
- Several features, including AI Priority Inbox, reminders and sharing to Microsoft Teams, are Outlook-only
- No public API and no mobile application for iOS or Android

Data, GDPR & hosting
A consolidated view of how Flowrite handles your data.
GDPR overview
GDPR compliance is claimed explicitly: a GDPR Compliant badge appears on the security page and the homepage, and the privacy policy, effective 27 January 2025, lists the eight data subject rights. Maestro Labs has named an internal data protection officer, Sebastian Illing (sebastian@maestrolabs.com), and routes rights requests to support@maestrolabs.com, with support.uk@maestrolabs.com for UK users. Because the databases sit in the United States, which holds no Article 45 adequacy decision, transfers rely on standard contractual clauses under Article 46, described as enhanced in line with European Data Protection Board guidance. A data processing agreement is available on request. No Article 27 EU representative is named anywhere on the site. The policy adds that the company has received zero government requests for information since it was founded, and that Do Not Track signals are not honoured.
Who owns the data?
Maestro Labs Pte. Ltd., registered at 160 Robinson Road, #14-04 Singapore Business Federation Centre, Singapore, is the controller behind the service. It has appointed an internal data protection officer, Sebastian Illing, reachable at sebastian@maestrolabs.com. The privacy policy, effective 27 January 2025, makes the customer responsible for whatever they feed the tool: the vendor describes itself as a passive processor of User Content and expects users to hold the lawful basis for processing and to inform third parties whose data appears in their emails. The terms of service also allow Maestro Labs to display a customer company's name and logo in its own marketing materials.
Reuse rights
Collected data serves only to deliver and improve the products, analyse usage patterns and troubleshoot. Personal information is never sold and is shared only with providers that help deliver the service; it is never used for advertising or profiling. Email content and user instructions are passed to third-party AI models so the assistant can draft and summarise, and the policy concedes that anonymisation applies only in some cases. Fully anonymised usage data feeds improvements to internal systems and prompt logic, and the security page states that customer data is never used to train AI models. On the user's side, the terms reserve Maestro Labs' intellectual property over its own site and application material and forbid republishing, reselling, reproducing or redistributing it. They say nothing explicit about who owns the drafts the assistant generates, so that point is worth clarifying before building a published workflow on top of it.
Data retention & training
Hosting summary
Maestro Labs Pte. Ltd. is headquartered in Singapore, but the privacy policy is explicit that the databases are located in the United States and that information collected about users is processed there. Storage also runs on cloud database services located in the United States and the European Union, and the policy notes that the specific location depends on the service and infrastructure used rather than on where the user is. Because the United States has neither sought nor received an adequacy finding under Article 45 of the GDPR, transfers rely on binding standard contractual clauses under Article 46, which the company describes as enhanced in line with European Data Protection Board guidance. Data is encrypted in transit and at rest. A subprocessor list is published in the Trust Center at security.maestrolabs.com, and the company says subprocessor and transfer impact assessments are ongoing. Note that the Trust Center is rendered in JavaScript, so the list itself could not be read directly during this review.
Things to keep in mind
Risks and trade-offs to weigh before adopting Flowrite.
- The Flowrite name no longer maps to a product you can buy, so check carefully where you are creating an account
- Publisher and jurisdiction both changed, from Flow AI to Maestro Labs Pte. Ltd. in Singapore
- The advertised USD 12 rate locks you into a year that is non-refundable, and every plan auto-renews by default
- Email content and instructions leave for third-party AI models, with anonymisation applied only in some cases
- Leaning on an assistant for everyday correspondence can erode the habit of writing a difficult message yourself
- On the sibling meeting product, a deletion request may be refused when other participants share access to the same record
- No minimum age is stated, Do Not Track signals are not honoured, and no Article 27 EU representative is named
Setup & Integrations
Technical difficulty
Very low. Nothing is installed locally: the Outlook add-in comes from the Microsoft Marketplace and the Gmail version from the Chrome Web Store, and the site repeats that no software and no credit card are needed. After signing in at dashboard.maestrolabs.com, the interface amounts to three buttons, Compose, Reply and Improve. There is no API key and no configuration to write. The one realistic obstacle is organisational rather than technical: in a managed Microsoft 365 tenant, an administrator may have to approve the add-in first.

Should you pick Flowrite?
Flowrite is best read today as an archive entry with a forwarding address. The brand no longer sells anything: Maestro Labs bought the AI email writing business and moved it into MailMaestro, while the original team went back to Flow AI and LLM evaluation. Anyone arriving at flowrite.com expecting to sign up will be redirected, and that is the single most useful thing this entry can tell them.
The successor is a credible landing spot. MailMaestro does what Flowrite did, turning a short instruction into usable drafts, answering threads in context and summarising long conversations, and it does so inside Outlook and Gmail rather than in a separate window. The compliance work behind it is stronger than the price suggests, with SOC 2 Type II, GDPR, HIPAA and CASA Tier 2 all claimed, a stated refusal to train on customer data, and zero-day retention offered to enterprise buyers.
The reservations are real. The free plan's three requests a week are a demonstration rather than a working allowance. The USD 12 headline needs an annual, non-refundable commitment, while month to month costs USD 15. Several of the more interesting features never left Outlook. Email content still travels to third-party models, and the privacy policy is candid that anonymisation is not systematic. Databases sit in the United States, so an EU-only residency requirement will not be met.
Treat every figure here as a snapshot. The transition page carries no date, the publisher's own adoption numbers disagree between pages, and pricing on an acquired product is exactly the sort of thing that moves without notice. Check the current terms on the vendor's site before committing a team to it.
