Pricing overview
Thesify runs two paid annual plans — Reviewer and Coauthor — priced in euros, both confirmed directly on the official pricing page. There's no tiered credit system to track: each plan is a flat annual price with a free trial attached. Because pricing can change, treat the figures below as a snapshot and confirm current numbers on the official Thesify pricing page.
Free trials
Reviewer includes a 7-day free trial; Coauthor includes a 14-day free trial. Both can be cancelled before the trial ends to avoid being charged, which makes it straightforward to judge the feedback quality on a real manuscript before committing to the annual price.
Plans and pricing
| Plan | Price | Best for | Highlights |
|---|---|---|---|
| Reviewer | €75/year | Manuscript feedback and citation search | PDF feedback reports, chat-with-manuscript, article/journal search, paper digest, topic suggestions, collaborative space, AI chat assistant (Theo). 7-day free trial. |

A note on monthly billing
Thesify's pricing page indicates a monthly billing toggle exists, but the exact monthly rate for either plan didn't reliably extract during this review, and third-party figures we found conflicted with the official annual math — so rather than guess, we're not publishing a monthly number here. Check the official pricing page directly if paying monthly matters more to you than the annual rate.
Which plan should you choose?
- • Reviewer — you have a draft and want structured feedback plus citation search before submission.
- • Coauthor — you're actively drafting and want an AI research agent, collaboration and version history built in.
Is Thesify worth it?
At €75–90/year, Thesify is inexpensive relative to hiring a human editor, and its explicit refusal to ghostwrite — feedback and research support only — is a genuinely different pitch from AI writing tools that draft for you. The trade-off is a thin independent review base, so most of what you can verify about real-world results comes from trying the free trial yourself rather than from a large body of outside reviews. Given the low annual cost, using the trial to test it against a real manuscript is the lowest-risk way to decide.
Frequently asked questions
Is Thesify free to use?
Thesify offers free trials — 7 days on Reviewer and 14 days on Coauthor — that can be cancelled before billing starts. A separate free-plan signup link exists but its exact feature scope isn't confirmed on the official site.
How much does Thesify cost?
Reviewer is €75/year and Coauthor is €90/year, both confirmed on the official pricing page.
Can I pay for Thesify monthly instead of annually?
A monthly billing option appears to exist on the official site, but the exact monthly price wasn't clearly published at the time of this review — check the official pricing page directly if you need to pay monthly rather than assuming a pro-rated annual rate.
What's the difference between Reviewer and Coauthor?
Reviewer covers manuscript feedback, citation search and journal recommendations. Coauthor adds AI research agents that help search literature and draft, plus real-time collaboration, version history and a LaTeX-mode editor — aimed at active drafting, not just feedback on a finished draft.
Does Thesify have a free plan, not just a trial?
A signup link referencing a free plan exists, but its feature scope isn't confirmed on the official pricing page — the two things that are confirmed are the paid annual plans and their respective free trials.
Can I cancel before being charged?
Yes — both trials (7-day Reviewer, 14-day Coauthor) can be cancelled before the trial ends to avoid being charged.
