Polished and structured. Example: “Hello, I sent the document yesterday. Could you please confirm that you received it?”

How it works

Three steps, a few seconds

No setup, no plugin, no document to upload. Fluentsmith works on the text you paste and gives it straight back.

  1. Step 1

    Paste your text

    Up to 6,000 characters — an email, a Slack message, a whole section of a report. Rough drafts are fine.

  2. Step 2

    Choose a tone

    5 tones: Formal, Casual, Direct, Persuasive, Summary. On Pro you also choose the output language.

  3. Step 3

    Read it, then copy it

    The rewrite appears beside your original so you can compare the two before you send anything.

Examples

The same message, before and after

Worked examples of what the rewrite does. These are demonstrations of the tool, not customer quotes.

Chasing a late reply

Formal

Before

Hi, I already send two emails about the invoice and nobody answer me. I need this today.

After

Hello, I have not received a reply to my two earlier emails about the invoice. I need it today.

Message to a Slack channel

Casual

Before

the staging env is down again, third time this week, can someone from infra look at it

After

Staging is down again — third time this week. Could someone from infra take a look when they get a moment?

Reply to an unhappy customer

Formal

Before

We cannot refund you because the policy is 14 days and you passed. Sorry.

After

I am sorry, but we cannot issue a refund because your purchase is outside the 14-day refund window.

Tones

Five tones, and what each one actually does

Each example below rewrites the same draft: “Hello, I send the document yesterday. Please tell me if you received.”

Formal

Polished and structured

Hello, I sent the document yesterday. Could you please confirm that you received it?

Casual

Warm and conversational

Hi! I sent the document yesterday. Could you let me know if it arrived?

Direct

Concise and unambiguous

Please confirm receipt of the document I sent yesterday.

Persuasive

Confident and convincing

Could you confirm that the document I sent yesterday arrived? That one reply is all I need from you.

Summary

Shorter, every fact kept

Hi, I sent the document yesterday; please confirm receipt.

Not sure which one fits? Run the same text through two tones and keep the version you would actually send.

Languages

Write to 6 markets without switching tools

Free rewrites come back in English. Fluentsmith Pro lets you choose the output language, so the same draft can go to a client in Madrid and a supplier in Milan.

On the move

The same tool, one thumb wide

Most awkward messages are written on a phone, between two other things. Fluentsmith opens in the browser, the text box is full width, the tone row scrolls, and the copy button is where your thumb already is.

  • No app to install and no login to remember
  • Result appears under your text, ready to copy
  • Works the same in Chrome, Safari, Firefox, and Edge

Privacy

What happens to what you paste

Four facts, all of them written into the Privacy Policy you can read in full.

Not training data

Your text is sent to the model to produce your rewrite. Fluentsmith does not train models on your text; our AI provider does not use commercial API data for training by default. See our Privacy Policy for provider retention.

The text stays yours

You keep every right you had in what you paste, and in what comes back.

No sign-up, no password

The free rewrite needs no email. An email identifies only a Pro purchase, and you can request deletion, subject to the billing and legal retention requirements in our Privacy Policy.

Paddle handles checkout

Paddle, our merchant of record, takes the payment and issues the invoice.

Read the Privacy Policy, Terms of Service and Refund Policy.

Questions

Before you paste anything

Is Fluentsmith free?
There is a free tier: 1 rewrite a day, in English, with no email and no sign-up. Fluentsmith Pro is $19 a month, with unlimited rewrites and 6 output languages.
Is my text used to train AI?
No. It is sent to the model only to generate your rewrite, and Fluentsmith does not train models on it. Our provider’s commercial API policies apply; see our Privacy Policy.
Will the rewrite change what my message says?
Fluentsmith is instructed to preserve facts, dates, numbers, uncertainty, and commitments while changing wording, grammar, and tone. AI can make mistakes, so review the result before sending.
Who charges me, and can I get a refund?
Paddle, our authorized reseller and merchant of record, takes the payment and issues the invoice. Every purchase has a 14-day refund — see the Refund Policy.
Can I cancel the monthly plan?
Yes. Open Billing & support, verify your purchase email, and confirm cancellation. Renewal stops, and Pro remains active until the end of the paid period unless refunded.
Do I need to install anything?
No. Fluentsmith runs in the browser on desktop and phone. There is no extension to install and no document to upload.
How long can a text be?
Up to 6,000 characters per rewrite — including spaces and line breaks — on both the free plan and Pro.
