Decision cue: AJE and Enago are both established manuscript editing services with 20+ year track records, thousands of editors, and global operations. AJE has Springer Nature backing. Enago has a unique AI+human hybrid review tier. For English editing, both are competent. The more important question is whether editing is actually what your manuscript needs.

The key differences
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 $29 Manusights AI Diagnostic 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 Manusights free readiness scan 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 60 seconds. 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
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 Manusights free readiness scan evaluates all of these in about 60 seconds. If the issues are methodological or structural, the $29 AI Diagnostic 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.
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. Check what your paper needs for free before deciding where to spend.
