Let AI Navigate, You Govern
Stop operating. Start mixing.
Speak, and your session moves. Amia is the mixing assistant you used to have to hire — it runs transport, edits clips, inserts and tunes plug-ins, and manages channels, groups, sends, I/O and entire sessions. Give it a precise move and it executes exactly; describe a problem and it proposes the chain. It runs inside the free Lang3 Bridge app, where subscriptions and your account live.
Transport, editing, plug-ins, channels, groups, sends, I/O and session setup — the busywork engineers once hired someone to do, handled from a single sentence.
Give a precise instruction and it simply gets it done. Or tell Amia what you hear — “my bass sounds muddy” — and it draws on an ever-growing body of mixing knowledge, thinks the problem through, proposes the answer and carries it out. Hand over raw tracks and it builds the session and an initial mix. The creative decisions stay yours.
Basic requests run right on your Mac. Every change is previewed before it runs, destructive actions ask first, and anything is one word from undo.
State a precise move, or just describe what you hear.
Basic requests are carried out straight away. For an Advanced request — when you describe a problem instead of naming the move — Amia thinks it through and returns a proposed chain and settings for your approval.
Every step is shown before it runs. Destructive actions always ask first.
It executes in your DAW with original values captured — one word walks anything back.

Amia frees your mind to make the decisions; our controllers give your hands something real to turn again. Two purpose-built surfaces — one for equalization, one for dynamics — connect through the free Lang3 Bridge app and follow your plug-ins with no manual MIDI setup. Hardware is still being finalized and opens for reservation after the software beta — join the list to be first in line.
A focused surface for shaping tone: endless, detented controls where one turn is one precise move, with every band’s value and state visible at a glance. No menus, no hunting through plug-in windows — just ears, hands and the decision.
A surface for dynamics — threshold, ratio, attack, release and makeup under your fingers, with gain reduction you can read in your peripheral vision while you listen. Compression becomes a physical gesture again.
Controllers open for reservation after the software beta. Leave your email and choose hardware updates — no deposit, no commitment.

Lang3 is built local-first. The Lang3 Bridge application runs on your own computer and operates your DAW there; your audio files and session/project files are not uploaded to us. This policy explains the limited information we do need to run the Lang3 AI Mixing Assistant (Amia), subscriptions, and device pairing.
The data controller is Lang3, LLC, a Delaware limited liability company, 34 Brier Avenue, Wilmington, DE 19805, United States. Contact: legal@lang3.co.
We do not collect or upload your audio recordings or DAW session/project files. Audio and session manipulation happens locally on your computer.
Your audio, your sessions/projects and your conversations are not used to train shared models. When an instruction requires cloud intelligence, the relevant text and minimal context are sent to our AI inference subprocessor (Volcengine Ark / Doubao) solely to generate a response for that request; it acts as a processor, not as a training source for shared models. Your personal memory/preferences are stored locally and encrypted by default, are tied to your private library, and are not shared to the cloud unless you enable such sharing.
We are rolling out regional deployment so requests can be served close to users and to support data-residency requirements; see our regional architecture notes. Until a region is available for your location, cloud requests are processed by the subprocessors listed above.
We keep account and billing records for as long as your account is active and as required for tax, accounting and legal obligations. Diagnostic and request metadata are retained only as long as needed for operation, support and security, then deleted or anonymized. You can request deletion of your account and associated personal data at any time.
Depending on where you live (including under the GDPR/UK GDPR and the CCPA), you may have the right to access, correct, export, or delete your personal data, to object to or restrict certain processing, to withdraw consent, and not to receive discriminatory treatment for exercising these rights. To exercise any of them, email legal@lang3.co.
The website uses only minimal, necessary storage and the cookies set by our payment provider during checkout. We do not sell personal data or use advertising/tracking cookies.
We protect data with encryption in transit, local encryption of private memory, and OS-managed secrets. Our technical measures are summarized on the Security page.
Lang3 is not directed to children, and we do not knowingly collect data from them.
We may update this policy; material changes will be reflected by the “Last updated” date and, where appropriate, notified in-app or by email.

These terms govern your use of Lang3 Bridge, the Lang3 AI Mixing Assistant (Amia), related software and the website (together, “Lang3”), provided by Lang3, LLC.
By creating an account or using Lang3 you agree to these terms. You must be able to form a binding contract and provide accurate account information. You are responsible for activity under your account and for keeping your credentials secure.
Lang3 automates actions inside compatible digital audio workstations (initially Pro Tools) — such as transport, editing, mixer control and plug-in adjustments — based on your voice or text instructions and, optionally, connected Lang3 controllers. Lang3 performs actions on your live projects; you remain in control and are responsible for reviewing and confirming actions and for keeping backups of your work.
Subscriptions begin with a 14-day free trial. A payment method is collected through Stripe to start the trial, but you are not charged during the trial. You may cancel at any time during the trial and you will not be charged.
You can cancel at any time from your account/billing portal. Cancellation takes effect at the end of the current paid period: until then you keep full access, and at period end the account moves to the free tier. Cancelling does not create a prorated refund for the remainder of a period.
Except where mandatory consumer law requires otherwise, subscription fees are non-refundable once charged, and access continues through the end of the paid period. You can avoid any charge by cancelling during the 14-day trial. Nothing in these terms limits any non-waivable withdrawal, cooling-off or other right granted to consumers under applicable law (including in the EU/UK); where such a right applies, it controls.
You retain all rights to your audio, sessions/projects and settings. You grant us only the limited technical permissions needed to perform requested actions on your machines and to process the minimum context described in the Privacy Policy. Because Lang3 operates a live DAW, you are responsible for your files and sessions; save copies where appropriate, review confirmations for higher-risk actions, and use the provided undo/rollback features. Lang3 is an assistant, not a substitute for your professional judgment.
Lang3 interoperates with third-party DAWs and plug-ins that you license separately; we do not provide those licenses. Third-party names and marks belong to their owners and are used only to describe compatibility — see the Trademarks & Third-party notices. Payment, AI inference and hosting rely on the subprocessors listed in the Privacy Policy.
Mixing suggestions and automated results are provided for convenience and reflect technical/knowledge-based guidance, not guaranteed artistic, technical or commercial outcomes. Lang3 does not provide legal, tax or financial advice.
To the maximum extent permitted by law, Lang3 is provided “as is” without warranties of any kind, and Lang3, LLC will not be liable for indirect, incidental, consequential or punitive damages, or for lost projects, data or profits, arising from use of the service. Nothing here excludes liability that cannot be excluded under mandatory law (including for consumers).
We may suspend or terminate accounts that breach these terms or abuse the service. You may stop using Lang3 and cancel at any time. Provisions that by their nature should survive (such as liability limitations and ownership) will continue.
We may update these terms; continued use after the effective date constitutes acceptance of the updated terms to the extent permitted by law.
These terms are governed by the laws of the State of Delaware and the United States, without regard to conflict-of-law rules, and disputes may be brought in the competent courts of Delaware, subject to any mandatory jurisdiction and non-waivable consumer-protection rights that apply where you live.

Lang3 controls a live digital audio workstation, so security and least-privilege access are core design goals. This page summarizes how we protect your data and your system.
Lang3 Bridge runs on your own computer and performs DAW automation locally through the operating system’s Accessibility layer and MIDI/HUI interfaces. Your audio files and session/project files remain on your machine and are not uploaded to us. Accessibility control is used only to carry out the DAW actions you authorize.
Checkout and card handling are processed by Stripe, a PCI-DSS Level 1 payment processor. Lang3 never sees, stores or processes your full card number; card data goes directly to Stripe.
When an instruction needs cloud intelligence, only the request text and the minimum necessary DAW context are sent to our inference subprocessor (Volcengine Ark / Doubao) to produce that response. Your audio, sessions/projects and conversations are not used to train shared models. Personal data is private to your account by default.
Computer seats are paired using a device token, and access is scoped to your account. The app requests only the OS permissions required for the automation and MIDI features you enable, and the setup wizard shows each permission before you grant it.
Cloud endpoints are served behind Cloudflare with transport security. Regional deployment and data-residency controls are being rolled out so requests can be processed within the appropriate region.
We retain account, billing and diagnostic data only as long as needed for the service and our legal obligations; you can request account and personal-data deletion via legal@lang3.co.
If you believe you have found a security issue, please report it privately to legal@lang3.co with a description and reproduction steps. We ask that you give us reasonable time to investigate and remediate before any public disclosure, and we will acknowledge valid reports.
Security questions: legal@lang3.co, Lang3, LLC, 34 Brier Avenue, Wilmington, DE 19805, United States.
Transparency note: this page describes our current security posture in good faith and is not legal advice; it will be reviewed alongside our Privacy Policy and Terms before commercial launch.
During the beta, support is direct and personal — write to us and a real person replies. There is no ticket bot or call center; the same small team building Lang3 reads every message.
Email support@lang3.co. We read every message and reply directly during the beta. For billing and plan changes, use Manage billing inside the Lang3 Bridge app; for privacy or legal matters, write to legal@lang3.co.
To help us fix things quickly, please include:
The beta deeply supports Pro Tools on macOS. Windows and additional DAWs (Logic Pro, Cubase, Studio One and others) follow in stages, and the L3EQ / L3DY controllers open for reservation after the software beta. Features may change and some guides are still being written — if anything is unclear, email us and we will help directly.
Guides, video tutorials, a searchable knowledge base and integrated ticket tracking arrive as the beta grows — for now, email reaches the team fastest.
Lang3 Bridge is the local control hub behind your whole setup — it runs Amia, links the L3EQ / L3DY controllers, and does the actual work in your DAW, connecting to Pro Tools when it opens. It is also your management center for subscriptions, seats, devices and plug-in mappings — all local-first on your own computer. Available for macOS today; Windows and additional DAWs are on the way.
You state the intent in plain language.
Dedicated hardware controllers, sold separately.
The local control hub & management center.
Plug-ins, transport, editing, mixer, groups, sends & I/O.
macOS 14 Sonoma or later, including macOS 26 Tahoe.
A Windows version is on the roadmap. Exact versions and requirements will be confirmed at release.
The steps below are for the Pro Tools edition — guides for additional DAWs will be added as they launch.
So the assistant can operate Pro Tools on your Mac. The setup wizard opens System Settings and walks you through it.
Install the included Lang3 preset (it assigns inserts & sends A–J and more), then select it under Pro Tools → Setup → Keyboard Shortcuts → Librarian.
In Pro Tools → Setup → Peripherals → MIDI Controllers, choose HUI as the type, then set both Receive From and Send To to Lang3 VC2. The wizard shows you exactly where.
The wizard finishes local setup for you, then you sign in to manage your Amia plan and seats — billing is handled securely inside Lang3 Bridge.
