Use English at work.
Get better at it.
A desktop workbench for professionals who communicate across languages. Every conversation you handle builds real skill — not temporary crutches.
Your intent (Chinese)
好的，我今天下午会发给你。价格有一些小调整。
Suggested reply
Sure, I'll send the revised pricing over this afternoon. There are a few minor adjustments to the numbers — I'll highlight the changes for your convenience.
You do this every day and
learn nothing
A client messages you in a language you're still learning. You can translate the words, but you can't tell if they're annoyed, being sarcastic, or gently declining. So you spend ten minutes drafting a reply, second-guessing every sentence — too casual? too stiff? accidentally rude?
Then the tool-switching loop: Google Translate for the message, ChatGPT for the reply, a dictionary for that one word, copy everything back. Tomorrow the same client writes again and you do the exact same thing. The tools get the job done, but nothing sticks — because nothing was designed to.
Do the work. The learning follows.
Fluent doesn't teach you a language. It helps you handle real conversations — and every time you do, you get a little better.
Paste. Understand.
Paste a message. Fluent shows the translation and detected tone together — so you know whether the client is frustrated, being polite, or making a request. The emotional layer that translation alone misses.
Hi, I wanted to follow up on the proposal we discussed last week. Could you send over the revised pricing by end of day?
Translation
嗨，我想跟进我们上周讨论的提案。你能在今天结束前把修改后的报价发过来吗？
Draft your reply.
Write your intent in your own language, pick a tone, see the result. Both versions appear side by side, so you absorb how the language maps — not just what to paste.

Words stick because you used them.
Tap any word to see its meaning in context. Fluent saves it and brings it back at the right time — but because you first met it in a real conversation, it already half-sticks.

Workbench + learning system
Every feature is built into the task you're already doing. A separate Learn mode exists for review — but it feeds entirely from your real conversations, not a textbook.
Real-Time Translation
Paste a message, see the translation and detected tone instantly. Tone detection surfaces the emotional layer non-native speakers miss — is the client frustrated, being polite, or making a veiled request? You grasp the subtext, not just the words.
“Could you send over the revised pricing by end of day?”
你能在今天结束前把修改后的报价发过来吗？
Multi-Tone Reply Drafting
Write your intent in your own language, pick a tone, see the reply. You don’t just copy the output — you watch your thought cross the language gap, and that’s where learning happens.
You type: 好的，我下午发给你
Sure, I'll send it over this afternoon.
Word Lookup
Tap any word mid-conversation for instant definitions and examples — in context, not a separate app.
Expression Collection
Useful phrases from real conversations are saved automatically. No manual flashcard creation needed.
Spaced Repetition
Words you looked up in real tasks come back at the right intervals. They stick because the first encounter was real.
Cultural Notes
Understand why a phrase works — the cultural subtext that textbooks skip but real conversations require.
Your client conversations are too
sensitive for the cloud.
Fluent runs entirely on your machine. No cloud sync, no tracking, no data leaving your device — ever.
Local-first
Your conversations and data stay on your device.
Encrypted API keys
Your API credentials are encrypted and never leave your machine.
No telemetry
Zero tracking, zero analytics. We don't collect any usage data.
Frequently asked questions
Everything you need to know before getting started.
Tomorrow, that client will write again.
This time, you'll be ready.
Every conversation you handle with Fluent makes the next one easier. The improvement compounds — and it starts with your first reply.
