Features
Everything you need to write, research, and ship documents
NextDoc combines frontier AI models, live web research, and your own files into one editor — so every draft starts grounded and ends client-ready.
Generate
Go from blank page to structured draft in one prompt.
One-prompt document generation
Describe the document you need. NextDoc returns a structured draft with headings, sections, and formatting in place — not a wall of text.
Word budgets & document types
Pick a type (report, proposal, brief, memo) and target length. NextDoc plans the structure to fit.
Auto table of contents
Long documents get a navigable TOC and consistent section flow without manual setup.
Tone & style controls
Set Professional, Casual, Academic, or Persuasive at generation time — applied across the whole draft.
Edit with AI
Refine any sentence, paragraph, or whole document inline.
Write mode for precision, Chat mode for questions, smart transforms for everything in between.
Write & Chat modes
Write mode makes precise inline edits. Chat mode answers questions about your document without touching the text.
Smart transforms
Shorten, expand, paraphrase, summarize, change tense, or shift tone on any selection — one click.
Custom prompts on selection
Highlight text, type any instruction ("make it more formal and concise"), and accept, reject, or retry.
Next sentence suggestions
Contextual completions as you write. Tab to accept, cycle through alternatives, or ignore.
Humanize AI content
Run a whole document or just a paragraph through humanization when a draft reads too synthetic.
