FROM FRAGMENT TO MANUSCRIPT
One connected writing practice
Long-form work grows one thought at a time.
Ideas rarely arrive in outline order. Strut keeps rough notes, developed passages, structure, and the full draft connected as the work grows.
Capture
Catch rough notes, fragments, quotations, and questions before they disappear.
Develop
Expand a promising note, connect related ideas, and discover what the piece wants to say.
Structure
Arrange material into an outline, sections, or chapters without losing the source context.
Write long
Build and revise the full draft with context-aware AI that follows your direction.
The long-form workspace
Rough notes nearby. The whole draft in view.
Outline, sources, version history, and a context-aware assistant around one manuscript - See how the writing workspace features connect instead of using four apps that pretend to cooperate.
DRAFT · 2,140 wordsSaved
Tools should hold context, not attention.
Every switch asks the writer to rebuild a small world: the reader, the argument, the evidence, the sentence that almost arrived.
A connected workspace protects that world long enough for an idea to become useful.✦ Strengthen this passage

A connected workspace holds the reader, the argument, and the half-finished sentence in place - So returning to the draft costs a minute instead of an hour.

What stays with the draft
One project holds the context the next sentence depends on.
A long piece is more than its current paragraph. Strut keeps the notes, evidence, structure, manuscript, and revision trail close enough to inform the work without turning every writing session into a search through old tabs.
Evidence stays traceable.
Import TXT, Markdown, CSV, PDF, Word, or spreadsheet files. Read selectable PDFs by page and save useful passages through the research workspace.
The outline and manuscript stay connected.
Keep documents, sections, word goals, and project material together so the long-form project still makes sense when you return days later.
Every accepted change stays reviewable.
Compare versions, inspect AI replacements as a word-level diff, and collect feedback through the review workflow before a draft moves forward.
Choose by workflow
Strut, a chat window, or an ordinary document editor?
The right tool depends on where the context lives and how much control you need over changes. Strut is built for projects that accumulate material and survive many writing sessions - Not for replacing every quick question or familiar document.
See the full writing-tool comparison| Writing need | Strut | Chat window | Document editor |
|---|---|---|---|
| Project context | Notes, sources, outline, and draft stay in one project. | Context is supplied through a conversation or separate project setup. | Context usually lives across files, pages, or folders you organize. |
| AI changes | Works on a selected passage and waits for your approval. | Returns a separate response for you to evaluate and place. | AI behavior varies by editor and plan. |
| Revision control | Saves a version first and shows replacement text as a word-level diff. | Comparison with the manuscript is usually manual. | Document history may exist; AI-specific review varies. |
| Without AI | Notes, editing, sources, versions, review, and export still work. | The conversation is the product. | Core drafting and collaboration still work. |
| Best fit | Long work developed from notes and evidence over multiple sittings. | Questions, brainstorming, and isolated text transformations. | Linear drafting and familiar document collaboration. |

See the workflowAI you can check
The assistant works on material you already own.
It never writes unasked
Every operation runs on a passage you selected and returns a suggestion beside your draft. Nothing is rewritten in place, so the manuscript only changes when you decide it should.
A version is saved first
Before any AI result replaces text, a restorable version is written. You can compare it against what came before and roll back to it weeks later.
Your writing is not training data
Text is processed only to complete the operation you asked for, and never used to train models. The privacy policy states this plainly.
Everything works without it
Editing, notes, search, version history, collaboration, and exports keep working when the AI allowance runs out. The workspace is not a wrapper around a model.
Before you start
Read the full guideQuestions people ask about writing with AI.
What is an AI writing workspace?
+
An AI writing workspace is a writing environment where your rough notes, research sources, outline, and full draft live together, and where the AI operates on that material instead of on an empty prompt. The difference from a chat window is context: the assistant already knows the manuscript you are working on.
How is Strut different from a chatbot?
+
A chatbot starts every session empty, so you re-explain your project before you can ask for anything. Strut gives you named operations - Expand, outline, strengthen, critique and more - That run on a passage you select, using the notes and sources already in the project.
Does Strut write the piece for me?
+
No. Every result appears beside your draft, not inside it, and only lands when you accept it. Replacements are shown as a word-level diff and a version is saved first, so any AI edit can be undone.
Is there a free plan?
+
Yes. A free account includes one project with up to three documents, unlimited notes and version history, imported sources, and 20,000 AI tokens to start. Returning users collect 2,000 more each day, up to 80,000 in total. No card is needed to start.
What kind of writing is Strut for?
+
Work that takes more than one sitting: essays, articles, reports, theses, newsletters past the short post, and book manuscripts. If a piece needs research beside it and structure to hold it, it fits.
Can I get my writing out of Strut?
+
Always. Any document exports as PDF, Word, Markdown, or plain text, and version history keeps earlier states of the draft. Nothing you write is locked to a plan.
