## Jenni

Jenni positions itself as an AI workspace for researchers rather than a generic chatbot. The environment combines a structured editor, a personal source library, chat, and citation tooling into a single surface, so you are not copying text between a draft document and an AI chat window. Sources stay attached to the sentences they support, which is the core idea behind its design: AI should write from your papers, not from generic web knowledge.

Practically, a project starts by building a library. You drag in PDFs, import Zotero or Mendeley collections, or search Jenni's academic index directly for papers, open-access full texts, and references. From there you write in the editor with AI autocomplete that draws on those curated sources. Suggestions arrive already cited, and each one can be traced to the original passage for verification. A supporting chat layer lets you ask questions across the same library.

The platform also leans into the realities of academic peer review. Its Reviews feature analyses every claim in a document, cross-references your sources, and flags issues across several categories, with inline feedback and citation analysis. Combined with flexible export options and support for many citation styles, this makes Jenni suited to essays, literature reviews, theses, and papers where the credibility of each statement matters.

**Pricing & Plans:** Jenni uses a freemium model with no credit card required. The Free plan includes 10 AI autocompletes per day, 10 PDF uploads, 5 AI chat messages, and unlimited citations. Plus is a mid-tier paid plan that adds 5,000 autocompletes per month, unlimited PDF uploads, 500 AI edits, 500 chat messages, and 10 Reviews per month. Pro is the top individual plan with unlimited autocomplete, uploads, AI edits, AI chat, Reviews, and workflow runs, plus priority support. Prices are listed in USD with annual billing discounts available.

- **Traceable, source-grounded citations:** Every AI-suggested sentence in Jenni links back to the precise page and paragraph in your source PDF, so claims stay traceable and easy to check.
- **Library building and research discovery:** Import PDFs, or bring collections over from Zotero and Mendeley, and let Jenni search an academic index of hundreds of millions of papers for supporting sources.
- **AI chat over your own sources:** AI chat answers questions across your full library with cited responses, so you can compare findings or unpick a methods section in context.
- **10,000+ citation styles:** Generate inline citations in 10,000+ styles, including APA 7th, Chicago, Harvard, IEEE, Vancouver, and journal-specific formats.
- **Reviews for claim analysis:** Reviews scans your draft for unverified or speculative claims across six categories, helping you catch weaknesses before peer reviewers do.

**Strengths:** Citations are tied to specific pages and paragraphs in your own sources, which supports honest, verifiable writing; Combines library management, drafting, chat, and citation tooling in one workspace instead of several apps; Broad format support, including Zotero and Mendeley imports and export to .docx, LaTeX, and HTML; Reviews feature targets a real pain point by surfacing weak or speculative claims before submission

**Limitations:** Free tier caps AI autocompletes at 10 per day, which can feel limiting during intensive drafting sessions; It is purpose-built for academic writing, so marketers and fiction writers may find the structure less flexible; Reliance on AI-suggested sentences still requires careful human verification to keep arguments your own

## Lex

Lex is built around a simple premise: the editor should stay out of the way while the AI does useful work at the moment you need it. The interface is deliberately minimal and keyboard-driven, so you write in a distraction-free document rather than assembling blocks in a page builder. Sitting alongside the text is an AI layer that can critique your draft, brainstorm directions, rewrite a sentence or paragraph, and generate title ideas on demand.

For anything longer than a quick note, Lex behaves like a proper collaborative document tool. You can share a link so a collaborator logs in with a single click and types alongside you, leave comments navigated by keyboard shortcuts, and switch between versions to try a different phrasing without losing what you had. Publishing sends a read-only link for readers, and mobile web access means a shared link works without anyone installing an app.

One practical note for anyone evaluating it today: Lex currently displays a notice stating it is no longer accepting new customers, while existing accounts continue to work as usual. If you are already using Lex, the product is operational. If you are new, you may not be able to sign up right now.

**Pricing & Plans:** Lex has operated on a freemium model with free and paid tiers; the site currently states it is no longer accepting new customers, so new signups may not be available. Existing accounts keep working and pricing details remain published on the site.

- **AI feedback on your draft:** Ask the built-in assistant to critique a passage, brainstorm alternatives or rewrite something, without leaving the document.
- **One-click commands:** Keyboard-driven AI shortcuts find the better word, expand a bullet into prose or generate a list of ideas in place.
- **Comments and versions:** Threaded comments navigated by shortcut plus saved versions, so you can try a different way of saying something without losing the original.
- **Live collaboration and publishing:** Share a link for one-click co-editing in real time, or send a read-only link so others can simply read the finished piece.
- **Title generation:** Request a batch of title options from the AI and pick the strongest headline instead of agonising over the first line.

**Strengths:** Genuinely minimal, keyboard-first editor that stays out of the way of writing; AI assistance is embedded in the document rather than living in a separate chat window; Proper collaboration features: live co-editing, comments, versions and read-only publishing links; Works on mobile web through a shared link, so collaborators install nothing

**Limitations:** The site currently states Lex is no longer accepting new customers, so new users may be unable to sign up; Track changes was still listed as coming soon, so review workflows are less complete than a full office suite; AI features focus on wording and feedback rather than deep research or data analysis
