Alternatives
ThesisAI alternatives for writing a thesis you can call your own
ThesisAI promises “Up to 80 pages with ONE prompt”. You describe the document, it drafts the lot from papers you upload, import or find through Semantic Scholar, and it exports to LaTeX or Overleaf. For a researcher who wants a scaffold to tear apart, that has its uses. For anyone who has to submit a thesis as their own work, it's the whole problem.
If you want help with the research but not the prose, Paperguide and Ponder handle sources and link claims back to them (both will still draft if asked). Thesify critiques a thesis you wrote. Writefull and Paperpal edit inside Overleaf. EthiWrite, our own tool, sits at the far end from ThesisAI: it won't write paragraphs from a prompt.

The trouble with one prompt and 80 pages
The draft is the product. ThesisAI writes the whole document from one prompt, so your job turns into editing its text instead of writing your own. Pro then runs an extra pass over rhythm, transitions and word choice so the draft “reads like considered academic prose rather than a first pass”. To its credit, the FAQ is blunt about what you're holding: the output is AI-generated, and its Terms of Use “prohibit passing AI-generated output off as unaided human writing”. If your course needs the words to be yours, that leaves a lot of rewriting.
Trustpilot reviewers add practical complaints: drafts that ignore the length and editing instructions they gave, citations badly formatted or made up, download and formatting trouble, and charges they struggled to cancel or get refunded. The company has replied disputing some of these claims.
Nor does the pricing section list a free plan to test it with: only Basic and Pro, with a student discount on request. Basic is $5 a month billed yearly ($60) or $10 month to month, for 48 documents a year. Pro is $8 a month yearly or $16 monthly and adds Word export, a full citation report and that style and tone pass.
It does some things well. It imports up to 500 papers from uploads, Zotero, Mendeley or Semantic Scholar, checks every sentence of the draft against your sources and labels it supported, synthesis, not supported or contradictory, and states that it never trains models on customer content. Its positive reviewers mention an easy interface and responsive support.
What to look for in a ThesisAI alternative
A support check you can run on your own writing
ThesisAI's sentence-by-sentence support labels are its best idea. Look for the same instinct in a tool that works on text you wrote: Ponder flags citations that rest only on an abstract or a link, and Paperguide ties each claim to the exact sentence in the paper.
LaTeX support that reads your source
If your thesis lives in LaTeX, check that the tool reads the source itself. Writefull checks language directly in LaTeX inside Overleaf, and Paperpal's Chrome and Edge extensions support Overleaf as well.
A way to try before you pay
ThesisAI lists only paid plans. Five of the six tools below have free plans (Paperguide, Ponder, Jenni AI, Writefull and Paperpal), so you can see their output on your own chapter first. Thesify's Reviewer is the exception, with no free plan and no trial.
The best ThesisAI alternatives
1. EthiWrite
Full disclosure: this is our tool.
EthiWrite starts where ThesisAI stops: with you writing. Autocomplete offers a sentence at a time, capped at about thirty words, as grey text, and nothing enters the document unless you accept it. Citations come only from sources in your Library, and their labels are generated from the source record rather than composed by the model, so you won't get an invented reference.
Examiner Mode then reads your draft and flags unsupported claims, thin evidence and structural gaps, with no ability to change your text. There's a free plan. The gap for thesis writers is formatting: APA, MLA and Chicago only, against the 8 styles ThesisAI exports. If your department wants IEEE or Vancouver, you'll be formatting elsewhere.
EthiWrite editor with the Guide panel open (demo account, email blurred). Best for: Students writing their own thesis who want every citation traced to a source they added.
2. Paperguide
Paperguide is the strongest replacement if what you liked about ThesisAI was the research engine. It searches 200M+ papers across PubMed, arXiv, OpenAlex and Semantic Scholar plus your own library, imports from Zotero or Mendeley, and switches between 1,000+ citation styles. Extract Data builds a table from many papers with every value linked to the statement it came from.
It drafts too: the AI Writer can generate a citation-grounded draft from a research question, though you can write yourself with the agent alongside. Free use is 2,000 AI credits a month. Plus is $12 and Pro $29 a month per seat, both billed annually. Trustpilot reviewers praise the search and extraction, while a doctoral student on an annual plan reports frequent errors and crashes.
Paperguide dashboard, signed in to a free account (the account name is removed). Best for: Researchers who want ThesisAI's source handling with claim-level links, and who will write the text themselves.
3. Thesify
Thesify turns ThesisAI around: you bring the thesis and it tells you what's weak. Reviewer accepts documents of up to 100,000 words or 100 pages and returns a downloadable report on argument, clarity and methodology. Highlight a passage and you can search 200+ million references and add citations to the document.
You pay per review, from €14.95 for one to €99.95 for ten, or €24.95 a month for three. There's no free plan and no Reviewer trial. A competing service's review judged it a good fit for thesis feedback but not a journal-readiness check, and noted it doesn't verify citations.
Thesify reviewer, signed in to a free account, before any document is uploaded. Best for: Graduate students who want a structured critique of their own thesis before a supervisor reads it.
4. Writefull
Writefull covers the LaTeX side of the job. Inside Overleaf it checks language directly in your source and can generate LaTeX tables and equations, and it also works in Word. Models trained on published papers drive its feedback, and it says your text is never stored or used to train its AI.
It won't find, manage or format sources, so keep a reference manager. The free plan is a limited quota of each feature; Premium is US$21 a month or US$150 a year. It isn't wholly hands-off on writing either: the Abstract Generator drafts an abstract, and the site promotes a separate Papers AI product for whole manuscripts. On r/academia, LaTeX users valued it, while others saw it correct mathematics as if it were prose.
Writefull Academizer run on its own example sentence, signed out (the Word and Overleaf tools need an account). Best for: Researchers writing in Overleaf who want academic-style language edits on their own text.
5. Jenni AI
Jenni AI sits between drafting everything and drafting nothing. Its autocomplete proposes sentences as you type and can be restricted to your own library, and its AI chat answers questions about your sources with citations. Papers come in from PDFs, Zotero, Mendeley or its own 200M+ search, citations format in 10,000+ styles, and each suggested sentence links to its spot in the source PDF.
Accepting suggestion after suggestion still adds up to text you didn't write: one reviewer built a 250-word introduction mostly that way, and a detector flagged all of it as AI-generated. The free plan has 10 autocompletes a day with unlimited citations. Plus costs $12 a month and Pro $29.
Jenni AI editor, signed in to a free account. Best for: Writers who want sentence-level help tied to their PDFs instead of a whole generated draft.
6. Ponder
Ponder suits you if you'd rather understand a literature than generate one. Mind maps, paper lists, documents and slides share one project, its search covers 320M+ scholarly works beside your own PDFs and Word files, and every AI edit is saved as a version you can roll back. Before export it re-checks for retracted sources.
Ask it to and its Draft stage writes literature reviews and papers from your sources, so keep the same caution you'd keep with ThesisAI. It runs on credits: 50 a day free, then Casual at $14 a month billed yearly ($168) or $16 monthly. Video reviewers like tracing each card back to its passage, though independent user reviews are scarce.
Ponder public homepage, signed out (the workspace needs an account). Best for: Researchers mapping a field before they write who want each citation to open its source paragraph.
7. Paperpal
Paperpal is a polish-and-check tool for the final stretch, working in Word and, through Chrome and Edge extensions, in Google Docs and Overleaf. It runs 30+ pre-submission checks against journals' language and formatting standards and compares your text with 99B+ sources for plagiarism.
Free use covers 200 grammar edits a month, five files a month of chat with papers, and lite plagiarism and journal-fit reports. Prime and Pro bill monthly or annually, but prices only show once the page loads them for your region. On r/research, commenters were sceptical of AI editing for research writing, warning it can blur what you meant.
Paperpal editor on its built-in sample document, signed in to a free account. Best for: Researchers preparing a manuscript who want journal-style checks in the editor they already use.

The bottom line

FAQ
- Is ThesisAI free?
- Not on any plan it lists. The pricing section shows only the paid Basic and Pro plans, though it offers a student discount on request.
- Can I hand in a ThesisAI draft as my own work?
- Its own FAQ says the output is AI-generated and points you to your institution's policy, asking you to disclose AI use where it's required. Its Terms of Use go further and “prohibit passing AI-generated output off as unaided human writing”. So not as unaided work. Whether a disclosed, reworked draft is acceptable is your institution's call, not ThesisAI's.
- Are ThesisAI's citations real?
- It cites from papers you upload, import or find through Semantic Scholar, and labels each sentence against those sources. Even so, some Trustpilot reviewers say citations were sometimes badly formatted or made up, so check each one yourself.
- Which alternative works best with Overleaf?
- Writefull, if you want language edits: it checks LaTeX source directly inside Overleaf. Paperpal's browser extensions support Overleaf too. ThesisAI itself exports to Overleaf, so you can keep editing there whichever tool you pick.
- Is there an alternative that won't write my thesis at all?
- Thesify's FAQ says it will not write your paper, and its Reviewer only gives feedback, though its newer Coauthor workspace has agents that draft alongside you. EthiWrite, which we make, won't write paragraphs from a prompt either; its Autocomplete offers short continuations that you accept or ignore.
