Why it matters

AI made everyone a writer. Sounding like you is the hard part.

You’ve seen the article. Everyone has. It opens with “in today’s fast-paced world,” promises to delve into things, and reads exactly like the other four pieces chasing the same keyword, because the same model wrote all five. And it’s not just the same phrasing: look closer and they all give the same advice, too. The industry has a word for it now: AI slop.

In the agentic era everyone has the same models. The only input nobody else has is you. So this editor is built around exactly that. Not AI that writes content for you. AI that writes it with you: your research, your context (files, website, notes), your rules, your feedback, your keyboard.

Why not just ChatGPT?

Great writers. Not editors. Not yours.

Claude and ChatGPT write genuinely well. Plenty of marketers draft in them every day. But a wall of text and a copy button is fine for average content. It’s not how you make something yours.

The same draft, but with handles on every sentence.

01 —The handoff

It starts with the research attached.

This is the same invoicing brief the research page finished building: keyword, target length, the outline you refined, the gap you claimed. One click, and it’s a document: the outline becomes the skeleton, and the research rides along as context every agent run reads.

No research yet? Start anywhere. Pick a content type and write immediately, or import a live page by URL, Markdown, or copy & paste. The research attaches whenever you’re ready, never as a toll gate.

the draft starts from what ranks, not from a blank prompt

The outline you refined on the research side, attached and machine-readable, with 6 of 10 ranking results read in full.

02 —The draft

Agents draft like a team doing the work.

Brief it in plain language. The agent shows its plan, reads the attached research, searches the web when it needs a fact. And when something is genuinely your call, it asks before it assumes. Every step is on the record: the plan, the sources, the reasoning.

You also choose the minds. The Thinker, the Writer, and the Image model are picked separately, from eleven frontier models across four providers. The strategist, the wordsmith, and the illustrator don’t have to be the same brain.

H2What to do when it isn’t paid

Late payments are a process problem, not a personality one. Set the expectation on the invoice itself (due date, late fee, and what happens next) so the reminder is never a surprise.

The plan shown, sources fetched, questions asked: a run you can read, not a black box.

03 —The take-over

Your document. Take the keyboard anytime.

See a line you’d say differently? Take it. Click in mid-draft, strike the agent’s phrase, write your own. No re-prompting, no pasting into another doc to fix one sentence. Where a chat window stops, the editor begins: your hands, your ink. And the rules keep watch even when it’s you typing.

04 —The refinement

Surgical edits, offered as suggestions.

Agent mode is a conversation: you steer with what you say next. Targeted is an instrument panel: one block, one instruction, and every dial set before you press it (word count, tone, voice, even which model thinks). The change arrives as a suggestion: the old text struck, the new text inline, yours to accept or reject (one by one, or all at once).

Prefer speed? Flip the run from Suggest to Apply and the agent writes directly. The dial is yours, per run.

H2Payment terms that actually get you paid

Late payments are a process problem, not a personality one. Set your terms on the invoice itself, and the reminder is never a surprise.

It is generally considered a good practice to make sure that your payment terms are clearly stated, because unclear State your payment terms plainly: unclear terms can often lead to delays in getting paid.

If it still isn’t paid, spell out the late fee, firmly and kindly.

One block, one instruction, one reviewable diff. The rest of the draft never moves.

05 —It learns you

Everything it knows about you, in one place.

Prompt-and-paste AI forgets you the moment the chat ends. That’s how everyone ends up sounding the same. Agent Studio is where this editor remembers: your voice, your rules, your sources, your personas. Every run reads it, and every entry is yours to open, edit, or delete.

every memory yours to open, edit, or delete

A memory is one small, readable preference (told directly, learned from a writing sample, or caught in ordinary conversation), recalled by the agent into every run, so you never have to explain your voice twice.

06 —Multiple formats

One editor. Multiple formats.

Articles, news, commercial pages: the agent writes them all in the same editor. Long-form streams in as real blocks: paragraphs, tables, callouts, images generated in place. Commercial pages are born as typed blueprints (hero, features, social proof, call to action standing as ghosts) and fill section by section from one ask.

H2Tax lines (VAT & sales tax)

Tax is the line freelancers get wrong most. Charge it when your registration says you must, and show it as its own line, never folded into the fee.

RegionOn the invoice
EU (VAT)VAT ID + rate on every line
US (sales tax)state-by-state, often none for services
UK (VAT)registered? 20% standard

When in doubt, one rule holds: the invoice shows the tax, the contract explains it.

H3Net-30 vs. due-on-receipt
Net-30 is a loan you didn’t agree to make. Due-on-receipt with a 5-day grace gets you paid twice as fast: same politeness, shorter wait.

The article streams in as real blocks: paragraphs, tables, callouts, images. The page is born as a blueprint: empty sections the agent fills one by one, in the same editor, all of it yours to edit.

The full toolkit

The whole workshop. Nothing missing.

Seventeen more pieces working the same document: no add-ons, no tiers of the editor.

The editor
30+ block types

Headings to tables to columns to callouts. Shape it by hand like a modern doc editor, or let the agent do it.

Voice input

Dictate into the draft at talking speed, or speak the edit and the agent makes it.

Suggestions

AI edits land as tracked changes, not silent rewrites. Review each one, or accept or reject them all at once.

Comments

Threaded comments anchored to any block, with resolution. Suggestions land in the same review list.

Version History

Automatic snapshots before and after every agent run. Restore previews the changes first.

Import & Optimize

Bring a published page or any existing content in by URL, Markdown, or copy & paste, then optimize it against fresh research.

SEO Optimization

Scored against the research it started from: a live checklist that flips green, plus a meta description in your voice.

Export anywhere

Rich Copy & Paste that lands cleanly in Docs or WordPress, plus PDF, Markdown, and HTML. Never locked in.

The agent
Image generation

Generated inline with Nano Banana Pro, right where it goes. Pick the aspect ratio and resolution, or upload your own.

Web search

The agent searches the web mid-draft to check facts and pull current information, right inside the writing flow.

Content Blacklist

Ban the words that sound like AI wrote it: the model avoids your list, and retries automatically if one slips through.

Recipes

32 section types for commercial pages, each with its own formula (structure, blocks, length), tuned account-wide or per project.

Instructions Library

Save a prompt + settings once (model, voice, tone, length) and rerun it in one click.

Business Context

Your company, product, and audience: context every generation consumes.

Projects

Group documents under shared defaults (models, edit strategy, rules) that cascade to every doc.

AI controls

Pick the Thinker, the Writer, and the Image model separately, each with its own reasoning effort, per run.

Your own API keys

Bring your own OpenAI, Anthropic, Google, or DeepSeek keys: no rate limits or usage caps, metered on your account instead of our tiers.

The payoff

You, at agent speed.

Features are the flower. This is the fireball.

Your voice, at scale.

Drafts arrive already sounding like you (rules held, memory applied), and every edit sharpens the next one. Volume stops costing identity.

mill voiceyour voice

Always the driver.

You direct the runs, review the suggestions, and take the keyboard mid-sentence. The agents adapt around you, never the reverse.

copy-pastetake over

It compounds.

Prompts forget; your editor doesn’t. The tenth draft needs fewer edits than the first, and the gap between you and prompt-and-paste keeps widening.

prompt rouletteWriting Memory

Bold, safely.

Auto-snapshots before every run and suggestions you can reject make ambition cheap. Let the agent try the big restructure: the undo is right there.

Questions

Asked before the first draft.

Straight answers: voice, control, safety, and what happens to your content.

Like you. That is the point of the architecture. Writing Memory accumulates what the agent learns from your edits and feedback, Learn Voice extracts your style from a pasted sample, and Content Rules hold your standing guidance (voice, standards, banned words). Every run consumes all three. The more you write and edit, the more the next draft already sounds like you.

Writing Memory keeps small, readable preferences (voice, vocabulary, structure, formatting, audience, facts, and things to avoid), each one visible in Agent Studio, editable, and deletable. A nightly tidy merges duplicates and resolves contradictions, and every change it makes is undoable. Delete a memory with “never capture this again” and it lands on a blocklist the agent honors.

Yes. Terminology rules map banned terms to preferred ones, and any banned term in new text is flagged as a one-click suggestion, whether the agent wrote it or you did. Mark a rule HARD and it is non-negotiable. This page’s own demo bans “penalty” in favor of “late fee”: watch the rule catch it mid-typing.

It is a real editor: more than 30 block types, drag to reorder, comments, and a cursor that is always yours. Type anywhere, anytime, including mid-agent-run. Agent runs default to Suggest, so AI edits land as reviewable suggestions; flip to Apply when you want it to write directly. The document is a document, not a transcript.

It can’t ruin anything permanently. The editor snapshots automatically before and after every agent run, and before Accept all. Version History shows every snapshot with who wrote what; restore previews the exact changes first, and saves its own checkpoint before it touches anything.

Not by nine of the eleven, and we’ll name the exception rather than bury it. WordCrafter calls the providers’ paid APIs, and OpenAI, Anthropic, and Google don’t train on data submitted through theirs. DeepSeek’s API terms are the exception, so if that matters for your content, pick any of the other nine models. Your documents and your research are yours either way: we never train on them.

No. There are three doors. Start from research and the draft begins with it attached; start from a blank page and write with the agents immediately; or import a live page by URL, Markdown, or copy & paste and optimize it. Research makes the agents sharper, but it is never required.

Eleven frontier models across Anthropic, OpenAI, Google, and DeepSeek. And you pick the Thinker, Writer, and Image models separately, per run, each with its own reasoning effort. Bring your own API keys and premium models run uncapped, metered on your own account.

Four ways: rich Copy & Paste that lands cleanly in Google Docs or WordPress, PDF, Markdown, and HTML. Your content is never locked in.

Claude and ChatGPT are genuinely good writers. The difference is everything around the writing. A chat gives you one block of text and a copy button. WordCrafter puts the same frontier models inside a real editor: agents that edit specific blocks as reviewable suggestions, version history, comments, your research attached as context, and rules and memory that keep your voice consistent across every document, not one conversation.

An AI editor that writes with you, not for you. Write the piece only you could write.

The old way prompts, pastes, and publishes like everyone else. The new way writes with you, and learns.
