AI writing assistant for academic and long-form writing that autocompletes as you type, chats with your PDFs, and inserts citations in 2,600+ styles.

Overview

Jenni is an AI writing assistant built specifically for academic and long-form writing rather than one-line marketing copy. Its core interaction is inline autocomplete: as you draft, Jenni suggests the next sentence or paragraph and you accept it with a tap of the right arrow, so the document grows with you instead of being generated wholesale and then fact-checked. That human-in-the-loop design is the point — Jenni positions itself as a co-writer that keeps you in control of structure and argument. Beyond autocomplete, it lets you chat with uploaded PDFs to extract and synthesize sources, then insert references in more than 2,600 citation styles including APA, MLA, and Harvard; a built-in plagiarism check and a suite of rewrite, expand, simplify, and tone commands round out the editing toolkit. A web extension and version history extend the workflow beyond the desktop editor, and Jenni reports over 5 million users and 15 million papers written, which speaks to its traction in the student and research market. The product deliberately avoids the ‘write my whole essay’ framing that trips academic-integrity alarms; instead it emphasizes assistance — outlining, paraphrasing, and citing — which is why educators are more tolerant of it than of pure essay generators. Pricing is a simple three-tier ladder: a Free plan at $0 with 200 autocompletes per day and 10 PDF uploads (partial export only), a Plus plan at $12/month billed annually with unlimited autocomplete, unlimited PDFs, and 500 edits/chats per month, and a Pro plan at $29/month with unlimited everything and priority support. For anyone writing theses, research papers, SOPs, or literature reviews, Jenni collapses several tools — a paraphraser, a citation manager helper, and a drafting aid — into one editor.

Comparison

Compared to Grammarly, Jenni goes beyond grammar and tone to actually draft and cite long-form academic text, while Grammarly remains the sharper pure editing and proofreading layer. Against Quillbot, both paraphrase and summarize, yet Jenni adds inline autocomplete and PDF chat that Quillbot’s toolkit lacks. Next to Sudowrite, Sudowrite targets fiction and creative prose, whereas Jenni is purpose-built for cited research and scholarly writing.

Editor’s Review
4.4/5
Pros
  • +Inline autocomplete keeps you writing instead of staring at a blank page
  • +Chat-with-PDF and 2,600+ citation styles streamline academic work
  • +Generous free trial (200 words/day) with no credit card required
Cons
  • Free tier's 200-word daily cap is too small for real papers
  • Citations still need manual verification against the source
  • Less general-purpose than all-rounders like ChatGPT for non-academic text

Jenni is the most focused writing assistant for students and researchers who need to produce cited long-form work without leaving the editor. The autocomplete genuinely reduces blank-page paralysis, and PDF chat plus citation insertion save hours — but you must still verify every reference, and the free tier is barely a trial.
