Strut is an AI-powered writing workspace and notebook, positioned as a long-form writing tool that helps users turn rough notes into organized articles, reports, papers, and book manuscripts. It emphasizes a "from fragments to finished draft" writing process, keeping notes, outlines, chapters, and drafts in one place rather than scattered across multiple apps.
In terms of use, Strut is aimed at long-form writing that requires multiple sittings, such as articles, reports, papers, newsletters, and book manuscripts. It suits students, journalists, academic writers, technical writers, newsletter writers, and people who need to write grant applications, among others. The official description notes that many articles are not lost at the writing stage, but in the gap between reading and the first paragraph; Strut tries to protect this creative process by connecting notes, sources, structure, and drafts.
Main capabilities include: Capture rough notes, fragments, quotes, and questions; Develop promising notes and connect related ideas; Structure material into outlines and chapters without losing source context; Write long drafts using context-aware AI to build and revise complete drafts. The workspace provides outlines, sources, version history, and a context-aware assistant working together around a single manuscript.
In terms of usage, users can create projects in Strut, capture rough notes, import sources, draft in the editor, and export the finished manuscript. AI actions run based on the paragraph selected by the user, and results appear as suggestions beside the draft rather than directly rewriting the original text; they replace it only after the user accepts. Before replacement, a recoverable version is saved and shown as a word-level diff, so users can compare and roll back. Text is used only to complete the operation requested by the user and is not used to train models.
Regarding the free plan, a free account includes one project, up to three documents, unlimited notes and version history, source import, and 50,000 starting AI tokens; no credit card is required to start. In addition, daily visits can claim 2,000 AI tokens, accumulating up to 80,000. The Pro version removes all limits and offers a free trial. Even if the AI quota runs out, editing, notes, search, version history, collaboration, and export features remain available.
Strut also offers free writing tools that can be used without an account, including an outline generator, a writing brief generator, and a focus sprint planner. Documents can be exported as PDF, Word, Markdown, or plain text, and version history preserves earlier states of the draft.
Regarding limitations, official materials do not provide specific platform support, number of collaboratorslimits, integration capabilities beyond export formats, pricing details, or a specific feature list for the Pro version; this information is not currently provided.
