Monorail AI is an all-in-one AI content platform that lets you generate text, images, video, code, voiceovers, transcriptions, and more using leading AI models from OpenAI, Anthropic, xAI, Cohere, ElevenLabs, FalAI, and Speechify. The platform brings nine tools under one roof: Chat, Writer (Presets), Image Generator (Imagine), Video, Coder, Transcriber, Voiceover, Voice Isolator, and Classifier.
Credits are the usage currency on Monorail AI. Every time you generate content, credits are deducted from your balance based on the AI model used and the amount of content produced. Different models cost different amounts per token, image, or second of audio or video. You can view your current credit balance at any time from your account dashboard.
Credits may expire. Unused monthly credits from paid subscriptions do not roll over to the next billing period. Check your plan terms for specific details about credit expiry. If you have questions about your balance, contact support@mnrl.app.
All payments are generally non-refundable. Credits are consumed upon use and cannot be refunded. Monorail AI may consider refunds in exceptional cases such as verified technical failures or duplicate charges. See the Refund Policy for full details.
Monorail AI integrates models from a range of leading providers:
  • OpenAI — GPT series, Whisper, Sora, DALL-E
  • Anthropic — Claude
  • xAI — Grok
  • Cohere — Command
  • ElevenLabs — voice synthesis
  • Speechify — text-to-speech
  • FalAI — FLUX, Imagen, Veo, Kling
You can select the model within each tool before generating content.
You retain ownership of your content and outputs, subject to applicable law and the terms of the underlying AI providers. Monorail AI is granted a limited licence to process and display your content in order to provide the service. For full details, see the Terms of Service.
Yes. You can use generated content for commercial purposes, subject to the Terms of Service and any restrictions from the underlying AI model providers. Always verify commercial use rights with the specific model’s terms before publishing or distributing generated content commercially.
Monorail AI implements technical and organisational measures to protect your data, including encryption and access controls. Your prompts and inputs may be transmitted to third-party AI providers (for example, OpenAI and Anthropic) for processing. See the Privacy Policy for full details on how your data is handled.
Cancelling your subscription (downgrading to Freemium) stops future charges. Your current plan remains active until the end of the billing period. No refund is issued for unused time remaining in the billing cycle.
Yes. Upgrades take effect immediately — you gain access to the higher plan’s credits and features right away. Downgrades take effect at the end of your current billing period, so you retain your current plan’s benefits until renewal.
Generation may fail for several reasons:
  • Insufficient credits — check your balance and top up if needed
  • Content policy violation — your prompt may have triggered a content filter from Monorail AI or the underlying model provider
  • Provider outage — the underlying AI provider may be experiencing a temporary issue
  • Unsupported file format — confirm that your upload meets the format requirements for the tool
Check your credit balance and try again. If the problem persists, contact support@mnrl.app.
No. Monorail AI is not intended for individuals under 18 years of age. By creating an account, you confirm that you are at least 18 years old and legally capable of entering into a binding agreement.
