Voice paraphraser

Sealis

AI writing sounds like AI. Sealis rewrites it in your voice, and every correction you make teaches it a little more about how you actually write.


A draft, marked up

Watch a stiff draft turn back into yours.

AI generation leapt forward. Rewriting stayed stuck.

every other tool stopped here

In the last few years, AI went from generating stiff paragraphs to writing full essays, code, and emails on command. But the moment you ask it to rewrite something in your voice, you're back to square one. The same thesaurus swap you've been doing since 2015.

Solved

Generation

AI can now write a draft from a single sentence. The raw output of generation is better than most first drafts.

  • Produces coherent, context-aware text
  • Understands tone, format, and audience
  • Gets better with every model release
Still stuck

Making it sound like you

The moment a draft needs to sound like a specific person, existing tools hit a wall.

  • Grammarly corrects grammar, not voice
  • QuillBot swaps synonyms. Mechanical, flat.
  • ChatGPT paraphrases in its own voice, not yours
  • None of them learn from your corrections

The gap is real: you spend 5 seconds generating a draft, then 10 minutes editing it because it sounds like a robot wrote it. Generation solved the blank page. Nobody solved the last mile.


What it learned

It keeps the edits you actually make.

Your corrections are read back, and the changes you make more than once are kept and used again — the exact words you swapped, never a guess about what you meant. Make a change once and it waits; change your mind and it goes.

your edits, not our guesses

Learned from your edits

From 14 corrections
1

You change "reach out" to "ask"

From 6 of your edits

2

You change "we are" to "we’re"

From 9 of your edits

3

You cut "just"

From 4 of your edits

4

You change "utilise" to "use"

From 5 of your edits

5

You change "kind regards" to "thanks"

From 7 of your edits


It gets better

The more you edit, the less there is to fix.

A change has to show up in two corrections before Sealis uses it, so the first one teaches it nothing on its own. From there it builds: the more of your own edits it has to work from, the closer each rewrite starts out.

Corrections left per draft
50

Steep at first, then flat. Most of the work happens in the first few edits.

Corrections avoided, running total
1400

Every rule it learns applies to every draft after it, so the saving compounds.

Illustrative. How fast you get there depends on how much you write.


How it works

Three steps, about thirty seconds.

01

Give it something you wrote

An email, a text message, an essay, anything in your own words.

one sample is enough,
three is better

02

Paste the draft you want fixed

AI output, or your own stiff first pass, whatever needs loosening up.

takes about
thirty seconds

03

Edit what comes back

Change anything that isn't quite right, then save it.

this is the step
that does the work


What it won't do

No tone sliders. No house style.

Invent things

It rewrites what you gave it. It will not add a fact, a figure or a promise that was not already in your draft.

Make you sound like someone else

There is no tone slider and no house style. The only voice it works towards is the one in the samples you gave it.

no tricks, no masks

Train on your writing

Your samples and corrections stay on your account and are used only to write for you. Nothing you paste in trains a shared model.

your words stay yours


Why it's different

Other tools forget. This one remembers.

Most rewriting tools match a voice once and then forget. You correct the same thing every time, and nothing on the other end ever notices.

Sealis reads the edits you make to its output, works out the rule behind them, and applies that rule to everything it writes for you afterwards.

it doesn't just copy your voice once. It learns the corrections you keep having to make


Questions

The things people ask first.

How much of my writing does it need?

One sample is enough to start. Three or four gives it a much clearer picture. After that it learns more from your corrections than from new samples, so there's no need to keep feeding it.

Can it write something from scratch?

No, and that's deliberate. Sealis rewrites a draft you already have. It won't invent a paragraph, because it has no way of knowing what you meant to say.

What if I don't like the rewrite?

Edit it and save. That's not a workaround, it's the main loop. Your edit is exactly what Sealis reads to work out the rule it got wrong.

Who can see what I paste in?

Only you. Your samples, drafts and corrections are stored against your account and used only to write for you. Nothing you paste in trains a shared model.

Does it only work for email?

No. Anything you write in your own voice works, essays, messages, cover letters, documentation. The stiffer the draft, the more obvious the difference.

What happens when I hit the free limit?

Rewrites pause until the next month starts. Your samples, rules and history stay exactly where they are, and nothing is deleted.
