Voice paraphraser
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
Further to our call,I hope this email finds you well.I wanted toenquire about your availabilitycheck whether you have availabilitythis week to talk through the Q3 timeline.Kindly confirm when convenient.Please do not hesitate to reach out.
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.
AI can now write a draft from a single sentence. The raw output of generation is better than most first drafts.
The moment a draft needs to sound like a specific person, existing tools hit a wall.
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
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
You change "reach out" to "ask"
From 6 of your edits
You change "we are" to "we’re"
From 9 of your edits
You cut "just"
From 4 of your edits
You change "utilise" to "use"
From 5 of your edits
You change "kind regards" to "thanks"
From 7 of your edits
It gets better
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.
Steep at first, then flat. Most of the work happens in the first few edits.
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
An email, a text message, an essay, anything in your own words.
one sample is enough,
three is better

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

that does the work
What it won't do
It rewrites what you gave it. It will not add a fact, a figure or a promise that was not already in your draft.
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
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
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
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.
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.
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.
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.
No. Anything you write in your own voice works, essays, messages, cover letters, documentation. The stiffer the draft, the more obvious the difference.
Rewrites pause until the next month starts. Your samples, rules and history stay exactly where they are, and nothing is deleted.
