Run the Free Readiness Scan to see whether the real issue is scientific readiness, journal fit, figures, citations, or language support before you buy editing or expert review.
Quick answer: AJE vs Enago is mainly a choice between two editing-first workflows. AJE is the cleaner fit if you want flat-fee, publisher-adjacent editorial support. Enago is more interesting if the AI-plus-human Lite tier or broader review ladder matters. Both are still editing-first services, not readiness-diagnostic products.
AJE and Enago are both credible editing companies, but they solve mostly the same class of problem: manuscript presentation, readability, and general pre-submission polish. The better choice depends less on brand prestige than on whether you need flat-fee simplicity, multilingual support, or a lower-cost AI-plus-human check.
If the real risk is journal fit, claim strength, figure logic, or citation integrity, neither company is the real answer. This page is most useful when you are deciding between editing-service models, not when you are trying to predict editorial rejection risk.

In our pre-submission review work
In our pre-submission review work, AJE versus Enago is usually a workflow decision, not a scientific judgment decision. AJE is the cleaner buy when a team wants publisher-adjacent reassurance and a flatter-fee editorial product. Enago is the more interesting buy when the team wants a broader ladder of review options, lighter entry pricing, or wider language coverage.
We see the mistake when authors expect either one to answer a journal-readiness question those services are not built to resolve directly. Once the manuscript risk is about scope, citations, figures, or claim strength, the editing-vendor comparison becomes secondary to the readiness decision.
Quick Decision Guide
If your main question is... | Better fit |
|---|---|
"Which editing service feels simpler and more premium?" | AJE |
"Which one gives me more menu flexibility and cheaper entry review?" | Enago |
"Do I need a scientific readiness answer instead of editing?" | Neither first |
The side-by-side comparison

AI integration | No public AI tool | Peer Review Lite (AI+human hybrid) |
Fastest turnaround | 24 hours | 24 hours |
Languages | English focus | 9+ languages |
Re-editing guarantee | Yes | Yes (+ money-back for language rejection) |
Pricing model
AJE uses a flat-fee model for pre-submission review ($289) that does not vary by manuscript length. Enago uses per-word pricing for editing and tiered pricing for review. For a typical 5,000-word manuscript:
- AJE pre-submission review: $289
- Enago Peer Review Lite: $149 (AI report + human check)
- Enago Full Peer Review: $399+
Enago's Lite tier is the cheapest human-touched pre-submission review on the market. But "human-touched" means a human validates an AI-generated report. It is not the same as an independent human review.
Publisher backing vs technology investment
AJE's Springer Nature partnership means some journals recommend AJE by name. This is a marketing advantage, not a quality guarantee. The editing quality is comparable to other services.
Enago has invested more in technology: the Peer Review Lite product combines AI analysis with human validation, which is a more efficient model than pure human review. Enago also offers editing in 9+ languages, giving it stronger global reach than AJE's English-focused operation.
Pre-submission review depth
Review feature | AJE ($289) | Enago Lite ($149) | Enago Full ($399+) |
|---|---|---|---|
Reviewer type | Generic PhD | AI + human validation | Up to 3 generic PhD reviewers |
Citation verification | No | No | No |
Figure analysis | No | No | No |
Journal-specific calibration | General comments | 24 checkpoints | General comments |
Turnaround | Varies | 4 days | 5 days |
None of these tiers verify citations against live databases, analyze figures individually, or calibrate feedback against the specific editorial standards of your target journal. The difference between them is the depth of general commentary, not the type of analysis performed.
What researchers actually receive
AJE ($289): Margin comments in the manuscript. The reviewer adds suggestions about logic, flow, scientific detail, and presentation but does not add or remove text. The feedback tends to focus on structure and communication. AJE's sample review (available on their website) shows paragraph-level comments about framing and audience. For $289, this is competent but general.
Enago Lite ($149): An AI-generated report across 24 checkpoints, validated by a human expert. The checkpoints cover title, abstract, literature review, objectives, conclusions, figures, and limitations. The human reviews the AI output and adds commentary. This is structured and organized, but the human is validating machine output, not conducting an independent review.
Enago Full ($399+): Up to 3 human reviewers evaluate methodology, research rigor, and journal compatibility. This is the deepest option from either company, but at $399+ with generic PhD reviewers, the depth-per-dollar is questionable when the manuscript readiness check provides citation verification and figure analysis that Enago Full does not.
The real question: is this the right category of service?
Both AJE and Enago are editing companies that added pre-submission review as an upsell. The review is performed by the same pool of PhD editors who do language editing. This is not the same as a purpose-built manuscript review service that was designed from the ground up to catch the things that cause desk rejection.
The manuscript readiness check was built specifically to evaluate manuscripts for desk rejection risk, not to edit them. It assesses methodology, citation integrity, journal fit, and claim strength in about 1-2 minutes. If the scan shows the issues are about language, use AJE or Enago for editing. If the issues are about science, citations, or journal fit, editing services cannot help.
When to choose AJE
- your institution has an AJE partnership or discount
- you are submitting to a Springer Nature journal and want the endorsed service
- you prefer a flat fee with no word-count calculation
- English editing is the primary need

Run the free scan to see whether the issue is scientific readiness, journal fit, or citation support before paying for more help.
When to choose Enago
- budget matters and $149 for the Lite tier is more feasible than $289
- you need editing in a non-English language
- you want a hybrid AI+human approach
- your institution has an Enago partnership
When to skip both
If the issues with your paper are not about language, neither AJE nor Enago will solve the problems that cause desk rejection.
The most common desk rejection triggers at selective journals:
- scope mismatch (the paper does not fit the journal's editorial priorities)
- methodological gaps (missing controls, inadequate sample size)
- overclaimed conclusions (the language exceeds what the evidence supports)
- citation problems (missing key references, fabricated AI-generated citations)
- figure inconsistencies (data presentation does not match the text)
None of these are language problems. None of them are fixed by editing. And neither AJE nor Enago evaluates them systematically in their pre-submission review offerings.
The manuscript readiness check evaluates all of these in about 1-2 minutes. If the issues are methodological or structural, the manuscript readiness check delivers verified citations from 500M+ live papers, figure-level feedback, and a revision checklist calibrated to your target journal. That is a different category of feedback than what any editing service provides at any price point.
If the scan shows language is the main issue, then AJE or Enago makes sense. Start with the free scan to find out.
Fast decision matrix
The practical decision is not "Which company is bigger?" It is "What do I need the next paid service to do?"
If the manuscript mainly needs... | Better fit | Why |
|---|---|---|
English polishing plus a familiar, premium-feeling service | AJE | Flat-fee simplicity and strong brand reassurance |
A cheaper pre-submit touchpoint and broader language coverage | Enago | Lower-cost entry and wider language infrastructure |
Genuine judgment on desk-reject risk and journal ambition | Neither | That is outside the editing-first category |
Verified citations, figure scrutiny, and journal-specific scoring | Neither | Both services stop short of that layer |
That distinction matters because many buyers are not disappointed by poor execution. They are disappointed because they bought the wrong category. AJE and Enago can both be competent while still leaving the main submission risk untouched.
How to choose without overspending
Before paying either service, ask:
- is the draft already scientifically stable enough that language is the main remaining weakness
- would an outside editor improve the submission more than a method or fit review would
- do you need a reviewer-style challenge, or just cleaner presentation and flow
- if the service comes back with only general comments, will that still move the manuscript forward
- are you paying for a concrete bottleneck or for reassurance
If those answers point to language and structure, choose between AJE and Enago on price, workflow, and institutional comfort. If those answers point to science, fit, or editorial risk, start somewhere else first.
Submit If / Think Twice If
Submit if:
- you are clearly buying editorial support
- the manuscript's remaining problem is readability, polish, or general presentation
Think twice if:
- the paper's biggest unresolved risk is still reviewer skepticism, journal fit, or citation exposure
- you are comparing AJE and Enago before confirming that editing is the right category
Bottom line
AJE and Enago are both solid editing services. AJE has publisher backing and flat-fee simplicity. Enago has a cheaper AI+human option and broader language coverage. For English editing, choose based on price and institutional preference.
For pre-submission review that catches the things that actually cause desk rejection, both services fall short. manuscript readiness check before deciding where to spend.
