Amazon Comprehend Pricing vs Omev: Monthly Costs for SaaS Text Analysis

At 100,000 English texts per month, with 1,000 characters per text, using one standard sentiment analysis and one standard entity extraction, Omev costs $100. Amazon Comprehend costs $200 after its introductory free period, or $190 when the full eligible AWS free allowance remains unused. See the Omev NLP API pricing overview for the documented workload fit.

Provider	Monthly cost for this workload
Omev AI	$100
Amazon Comprehend	$200 after the free period

Amazon Comprehend is the AWS-native comparison option for the same two-function workload: one standard sentiment analysis and one standard entity recognition per text. In US East (N. Virginia), each feature costs $0.0001 per 100-character unit, with a 300-character minimum per request, according to the official AWS Comprehend pricing page. That means short texts can consume more billable units than their raw character count suggests.

For eligible customers, AWS provides 50,000 units per API per month for 12 months, starting with the first Comprehend request. The allowance applies to units, not 50,000 documents, and is available to both new and existing AWS customers. At 100,000 monthly texts, its effect depends on text length and whether the allowance is still available.

This comparison stays limited to Comprehend’s prebuilt standard sentiment and entity analysis. Comprehend also includes capabilities such as custom classification, custom entities, and syntax analysis, but those features fall outside this two-function cost scope.

These figures assume one standard document sentiment analysis and one standard entity extraction per 1,000-character text.

Monthly texts	Omev	AWS after free period
1,000	$1	$2
10,000	$10	$20
100,000	$100	$200

At 100,000 texts, applying the fully unused eligible AWS allowance reduces the AWS amount from $200 to $190.

Calculation details

Omev charges $0.0005 per started 1,000 Unicode characters per function, and AWS charges $0.0001 per 100-character unit per function, with AWS’s 300-character minimum. Omev rounds each request up to the next whole 1,000 Unicode characters; AWS rounds up to the next 100-character unit with a minimum of three units per feature per request. The AWS region is US East, N. Virginia. Calculations were checked on 20 October 2026. AWS provides 50,000 units per eligible API per month for 12 months. At 100,000 texts, the two functions consume 2,000,000 units; the allowance removes 50,000 units for each function, or 100,000 units in total at $0.0001 each, a $10 reduction, bringing the AWS total from $200 to $190. See the Omev NLP rate card and AWS Comprehend pricing. The totals exclude taxes, other cloud services and custom models.

Omev bills in 1,000-character blocks, so a 300-character text is charged as 1,000 characters; AWS bills three units per feature for a 300-character text. Based on the verified standard sentiment and standard entity-extraction model, the comparison at 100,000 texts is:

Characters per text	Omev	AWS after free period
300	$100	$60
600	$100	$120
1,000	$100	$200
1,001	$200	$220

Omev rounds each text up to the next multiple of 1,000 Unicode characters, while AWS meters each feature in 100-character units with a 300-character minimum. That makes the 300-character case favorable to AWS, but longer texts do not produce a fixed percentage difference. Crossing from 1,000 to 1,001 characters also creates a discrete Omev step, while AWS increases according to its 100-character units.

Is AWS free forever?

No. Amazon Comprehend offers 50,000 units per eligible API per month for 12 months, beginning with the first Comprehend request. The allowance is measured in 100-character units, not documents, and eligibility depends on the AWS account. After the free period or allowance is exhausted, standard usage charges apply. See AWS’s official pricing for current terms.

Does Omev require a monthly subscription or separate NLP activation?

No. Omev’s native NLP is available on every API key without separate activation and is billed against the normal balance, as documented in the Omev NLP documentation. Omev’s self-service offer uses pay-as-you-go top-ups from $10, rather than a monthly subscription.

Does this budget include custom model training?

No. The comparison covers standard sentiment analysis and entity extraction only. Omev documents no equivalent for custom classifier training, while AWS lists custom training and model-management charges separately from standard analysis. Review the AWS feature list before budgeting for custom classification or entities.
