Talk to every customer in their language — without changing a thing.
LangReply plugs into your existing email and apps. Incoming messages arrive translated into your language; your replies leave translated into your customer's. You keep your Gmail, Outlook, WhatsApp — LangReply works invisibly in the background.

A two-way translation loop, completely invisible
Connect your mailbox or app in one step. LangReply handles the round-trip so you never copy-paste into a translator again.
Your customer writes in their language
A message arrives in Spanish, Mandarin, Arabic — any language. LangReply detects it and delivers a translated version straight into your inbox, right next to the original.
You reply — we translate it back
You reply normally, in your own language, from your own inbox. LangReply translates your reply into your customer's language and sends it. They receive one clean, translated message.
✦ You never leave Gmail, Outlook or WhatsApp. There is nothing new to learn.
One platform for every conversation
Email is just the start. LangReply unifies translation across every channel your customers use.
Every language on Earth
200+ languages, powered by a neural engine hosted on our own servers. From English to Swahili, both directions, with context — not word-for-word.
Keep your current inbox
Connect Gmail, Outlook, Yahoo, iCloud or any provider in one step. Translations appear right in your normal inbox. No migration, no new app to open.
WhatsApp, Teams, Slack & Zoom
Native connectors via official APIs. Chat with customers on WhatsApp, coordinate on Teams and Slack, and auto-transcribe Zoom calls — all translated.
Call transcription & summaries
Turn recorded calls into searchable transcripts with automatic summaries, key points and sentiment — in the language you choose.
Real-time client risk scoring
Every message is scored live for churn, complaints, legal and urgency signals — so your team spots at-risk customers before they leave.
Enterprise-grade security
Data encrypted at rest, role-based access, two-factor authentication and a full audit trail. Zero-Trust by design.
No per-message AI fees
The translation engine runs on our infrastructure — not a pay-per-word API. Translate as much as your plan allows, predictably.
The LangReply mention
Every relayed message carries a clear, professional note that it was translated by LangReply — full transparency for you and your customers.
Far more than plain translation
All recently added capabilities — included in every plan.
Multilingual SMS channel
A dedicated number per account. Your contacts text you in their language, you reply in yours. Automatic two-way translation.
Free LangReply messaging worldwide
Text other LangReply users over the Internet (like WhatsApp) — free worldwide, whether roaming or at home.
Mathematically irreversible deletion
Each message has its own AES-256 key. Delete = destroy the key. Content becomes unreadable forever, even by us.
Disappearing messages (like Signal)
Set each conversation to self-destruct after 1h, 24h, 7d or 30d. No trace survives beyond the chosen duration.
Find your contacts on LangReply
One-off import of your address book (native Contact Picker, CSV/vCard). Numbers are converted to non-reversible fingerprints on receipt; never shown to others, shared or sold.
Brand glossary
Your business terms respected across every translation, in every language, automatically.
Translation memory
Previously translated sentences are reused: guaranteed consistency and lower costs across all your exchanges.
Analytics dashboard
Volumes, languages, activity in real time. Prove ROI at a glance.
Anti-toxicity shield
Aggressive messages flagged automatically. Your teams protected.
Developer API + Chrome extension
Integrate LangReply into your apps via REST API. Chrome extension to translate pasted or selected text via your account.
Installable on mobile (PWA + native apps)
Install LangReply like a real app from Chrome/Safari. iOS and Android apps being finalized.
Honest, transparent security
AES-256 encryption at rest, TLS 1.3 in transit, strict per-account isolation, GDPR/CCPA. No empty promises.
New — Hardened security
Your translations, locked. Then wiped for good.
LangReply encrypts every message with a dedicated AES-256 key. When you delete, we destroy the key: the data becomes mathematically unrecoverable — even by us.
-
Irreversible erasure
Crypto-shredding: the AES-256 key is destroyed on delete. 2^256 remaining possibilities — irreversible in practice.
-
Disappearing messages
Signal-style: set a lifetime. On expiry the key is destroyed and the ciphertext becomes unreadable.
-
Encryption everywhere
AES-256 at rest, TLS 1.3 in transit, strict per-account isolation. GDPR and CCPA compliant.
Honest about limits
What we guarantee: once the key is destroyed, not even LangReply can read the message. What we do NOT guarantee: protecting data that has not been deleted yet, nor bypassing a lawful obligation on data that is still active.

Can I cancel anytime?
