About TXYZ.AI

What Is TXYZ.AI

TXYZ.AI is a research assistant that treats reading, searching, and writing as one workflow. You paste a paper URL or upload a PDF, ask questions in everyday language, and get answers that point back to the exact spot in the document. There's a search side that finds relevant papers across disciplines, and a writing side that drafts outlines and full articles from the sources you've collected.

The tool grew out of the ArXiv Labs program. In December 2023, ArXiv Labs picked the TXYZ plugin to help readers pull information from papers, and the team reported passing 500,000 users by January 2024. The company behind it is Path Integral, reachable at [email protected].

The main limitation is scope. TXYZ aims at academic and technical reading rather than general chat, so it won't write your emails or generate images. Its strongest features sit behind paid plans too: the free tier caps document uploads at 100 pages and gives only starter access to the Library and writing agents.

Getting Started

  1. Sign up at app.txyz.ai, or register a separate account at platform.txyz.ai if you want the developer API.
  2. Upload a PDF or paste a paper URL, or start from a search query if you are still gathering sources.
  3. Ask questions about the document and check the reference markers that link answers back to the text.
  4. Open the writing workspace to build an outline from your references, then expand it into a full draft.
  5. Add citations as you go, or describe the writing task to a personal agent so it can follow your field's conventions.

Key features

Chat With Papers and Documents

The core feature lets you upload a PDF or point TXYZ at a web page, then ask questions about the content. Answers come back with a document location reference, so you can check the claim against the original passage rather than trusting the summary blindly. The retrieval approach is built for research documents and handles both narrow, detailed questions and broad ones.

Natural Language Literature Search

TXYZ Searching understands everyday phrasing, so you can describe what you need instead of assembling precise keywords. It leans on semantic understanding to return conceptually related work, even when it lacks your exact words, and it spans multiple disciplines, which helps when a topic crosses fields. Results come from an academic paper database kept current as new publications appear.

AI-Assisted Writing Workspace

The writing side turns a research goal into a finished draft. You can auto-generate an outline from your references and AI conversations, then refine it with plain-language instructions. From there, TXYZ writes a full article using the information in your document, which suits researchers and content creators who need a coherent first draft without losing their own voice.

Automatic Citation Suggestions

When you write, TXYZ proposes sources based on your content and context and adds them as citations. This keeps the referencing step inside the writing flow instead of sending you off to a separate tool, and it helps students and researchers hold to citation standards in papers and theses.

Personal Writing Agents

You can build your own AI agent for specific writing tasks using existing building blocks. A researcher might set up an agent tuned to academic writing in their subject, while another user creates one for a particular style. The point is a reusable assistant that fits your habits rather than a single general-purpose model.

Developer API for Document Chat

TXYZ API connects your own app to the same AI engine. You upload PDFs by file or URL, chat with a bot that streams replies over SSE, and request suggested questions or document reference points. Credits drive the pricing, and the platform marks the session endpoints as free, with LLM calls costing one credit each. Teams have used it for medical research lookups, supply chain document analysis, and internal knowledge bases.

Privacy Controls

TXYZ states that uploaded papers stay private to the account holder and that deleting a private paper removes it from the database. Paid plans also carry a no-model-training commitment, meaning your interactions are not used to train the underlying models. The paid tiers support private sessions and bulk document uploads up to 300 pages on the Ultra plan.

Pros and cons

Pros

  • Answers include document references, so you can verify a claim against the original passage.
  • Search handles plain-language and multi-part questions, which cuts time spent guessing keywords.
  • Reading, search, and writing live in one place instead of three separate apps.
  • There's a free plan, and the API has a free tier with 100 credits for testing.
  • The no-model-training policy on paid plans matters for unpublished research.

Cons

  • The free plan limits document uploads to 100 pages and gives only partial Library and writing access.
  • It's built for academic and technical reading, so it does little for general chat or image work.
  • The most capable model and the 300-page upload ceiling require the $288 per year Ultra plan.
  • The API is credit-based, so costs scale with how often your app calls the model endpoints.
