DeepRails

DeepRails combines an AI development agency with a platform for evaluating and correcting model output. The publisher offers two routes: engage its team to build an application or use the platform through its playground and paid API plans.

Custom development and automation

The agency lists full-stack AI engineering, process automation, product management and fractional CTO or CAIO work. Its stated engineering scope includes model integrations, retrieval-augmented generation, agent workflows and evaluation layers.

DeepRails describes a discovery call followed by a scoped quote. For automation builds, it sets a fixed fee as a share of the expected first-year saving. The site says it measures the new system against the work the customer's team already performs, continues building if the agreed standard is not reached and includes six months of support after launch. Those are the publisher's proposed engagement terms. Establish the measurement criteria and obligations in the written scope before treating the advertised ROI guarantee as a result for your project.

Standalone hallucination platform

The pricing page describes real-time hallucination detection and correction for production AI. It says the platform underpins agency builds and is also available on its own. The paid Basic plan includes access to Defend and Monitor, while higher tiers add options such as custom guardrail requests and deployment arrangements.

The free offering provides restricted playground access, with no ticket support. It is a way to explore the described output-quality functions; the listed free tier does not include API access. The captured sources do not establish a universal detection rate or guarantee that a corrected response will be accurate for every task. Evaluate the platform against examples that represent your intended application.

Subscription and usage charges

The captured platform pricing lists Basic at $49 per month plus usage starting at $20 per thousand calls. Pro is $149 per month plus usage from $18 per thousand calls, and Enterprise is $499 per month plus usage from $15 per thousand calls. The page also shows annual billing controls.

Basic includes one seat, Pro ten and Enterprise unlimited seats. Each paid tier lists an initial credit amount and a different support level. Compare the subscription, call charges and selected billing cycle together; the base subscription is not the complete price of a production workload. Custom development uses engagement quotes rather than these standalone platform rates.
