Feature Comparison

PoYo API

Unified API Key and Integration

The platform eliminates the administrative burden of managing separate credentials for different AI services. Developers receive one master API key that grants access to the entire library of over 500 models across image, video, music, and chat domains. This unified approach drastically simplifies the initial integration process and ongoing key management, allowing teams to add or switch between AI capabilities within their application without reconfiguring authentication for each new model.

Credit-Based, Pay-As-You-Go Pricing

PoYo API operates on a flexible credit system, moving away from rigid monthly subscriptions. Users purchase credits upfront, which are then consumed based on their actual usage of different AI models, with each model having a clear per-task cost. This model provides significant financial clarity and control, as credits never expire and there are no recurring fees. It is ideal for projects with variable workloads, enabling seamless scaling up or down based on demand without contractual lock-in.

Comprehensive Model Library

The platform provides centralized access to a constantly updated catalog of leading AI models. This includes cutting-edge image generators like Nano Banana and Seedream 4, advanced video models such as Sora-2 and Veo3.1, complete music generation suites like Suno v4 and v5, and top-tier chat models including Claude Sonnet 4.5 and GPT-5. This diversity ensures developers can select the most suitable, state-of-the-art tool for any specific creative or analytical task within their application.

Developer-Centric Infrastructure and Support

PoYo API is engineered with practical development needs in mind. It features a simple two-endpoint async API for task submission and result querying, supports webhooks for real-time callbacks, and maintains low latency even under high concurrency. The platform is backed by robust monitoring for 99.9% uptime and offers 24/7 technical support from human experts. Additionally, a free playground allows for thorough testing and parameter tuning of all models without spending credits.

Speechable

Podcast Mode

Podcast mode transforms your document into a dynamic two-voice conversation, allowing you to choose the duration of playback—5, 10, or 15 minutes—and select your preferred language. This feature makes learning feel more like a dialogue rather than a monologue, enhancing understanding and retention.

Lecture Mode

Lecture mode presents complex ideas in a clear and straightforward manner, mimicking the style of TED talks. This feature is particularly useful for users who seek to grasp intricate subjects quickly and effectively, making it easier to absorb important information.

Eco Mode

Eco mode operates locally within your browser, which means it does not rely on cloud services. This results in up to 20 times less energy consumption compared to traditional cloud-based text-to-speech solutions. Additionally, it offers unlimited playback without any credits required, making it a sustainable choice for users.

Interactive Chat

The interactive chat feature allows users to engage with their documents by asking questions, either by typing or speaking. This functionality facilitates active learning, enabling users to clarify doubts or explore specific topics in depth, transforming passive listening into an engaging dialogue.

Frequently Asked Questions

PoYo API FAQ

What is the difference between PoYo API and using AI models directly from their original providers?

PoYo API acts as an aggregator and unified layer. Instead of integrating with dozens of individual providers—each with its own API documentation, authentication method, pricing plan, and rate limits—you integrate once with PoYo. We provide a single point of access, a consistent API structure, and consolidated billing. This saves significant development time, reduces complexity, and often provides cost transparency and stability not available when dealing with multiple providers directly.

How does the credit system work and do credits expire?

You purchase credits upfront through your PoYo account dashboard. Each AI model has a specific cost per task, measured in credits. When you make an API call to generate an image, video, etc., the corresponding number of credits is deducted from your balance. A key benefit is that these purchased credits do not have an expiration date. You can use them at your own pace, making it a truly flexible pay-as-you-go system without the pressure of monthly subscription cycles or use-it-or-lose-it policies.

Is there a way to test the API before committing funds?

Yes, PoYo API offers a free playground accessible directly on the model pages of the website. This interactive environment allows you to test every available AI model, adjust generation parameters (like image dimensions or style prompts), and see the outputs in real-time. This testing requires no API key and no credit card, enabling you to thoroughly evaluate model quality, speed, and suitability for your project before writing any integration code or purchasing credits.

What happens if an AI generation task fails?

PoYo API is designed with developer reliability in mind. If a task fails due to a platform or model error (not due to an invalid user request), you are not charged for that task. The credits are not deducted for failed generations. Furthermore, the dashboard provides tools for manual retry of failed tasks, giving you full control over the workflow. This policy ensures you only pay for successful, usable outputs, which is crucial for maintaining predictable costs in production applications.

Speechable FAQ

What file formats does Speechable support?

Speechable supports a variety of file formats, including PDFs, Word documents (.docx), ePubs, and web URLs, as well as photos of text. Users can easily drop their files or paste links, and Speechable will handle the conversion seamlessly.

How many voices are available?

Speechable boasts a selection of 52 natural-sounding AI voices across eight different languages. Users have the option to preview each voice and adjust playback speeds to suit their listening preferences, ensuring a personalized experience.

What is Eco mode?

Eco mode is a unique feature that allows Speechable to run text-to-speech processing locally on your device rather than in the cloud. This significantly reduces energy usage—up to 20 times less than traditional options—and provides unlimited playback without requiring credits.

Can I chat with my documents?

Yes, Speechable includes a chat feature that enables users to ask questions or request clarifications about their documents. This interaction mimics a conversation with the content, allowing for deeper understanding and exploration of the material.
