Video

Made with the latest video models

Veo, Kling, Seedance, Wan and more: from a sentence or a still image to a clip, many with sound.

Voice cloning

Clone a voice in three steps

Record a few seconds of your own voice or upload a clip, type any text and hear it spoken in that voice. It runs as a normal, billed model run in your account.

  1. 01Record or upload

    10 to 30 seconds of your own voice, right in the browser or as a file.

  2. 02Type your text

    Anything you want the voice to say.

    Hi! This is my cloned voice, made from a short sample.

  3. 03Hear your voice

    The model speaks your text in the cloned voice.

Only clone your own voice or a voice you have permission to use. You confirm this for every voice sample. Terms of Service

For AI agents

Your agent, every model

Connect Claude Code, Codex or any MCP client once. Your agent then searches the live catalog, compares prices and, with an API key, runs the models itself.

Live over MCP · no key

Describe the task. The catalog answers like it answers your agent.

This box calls the real tool recommend_model on our MCP server: a shortlist of models that can run right now, with the tool's reasons and prices.

Try

tools/call recommend_model

waiting for a task

{ "recommendations": [ … ], "no_match": false }

The answer appears here, exactly as your agent receives it: models, prices, reasons.

Same call, same answer as in Claude Code, Codex or Cursor.All tools

  • Works with Claude Code, Codex CLI, Cursor, Claude Desktop, VS Code and Gemini CLI.
  • Without a key: search the catalog, compare models and estimate what a workload costs.
  • With an API key: the agent runs chat, image, video and speech models, billed like the API.

Connect in one line

  1. 1Run the command in your project folder. Claude Code keeps the server for this project.
  2. 2Add --scope user to make the server available in every project.
  3. 3Check it: ask your agent “Which Railwail image models cost the least per image?” It should call search_models.

Without a key the server only reads catalog, prices and docs. Nothing to sign up for.

8 image models in the catalog match "logo" and can run right now. The first 3:

• LogoAI (SDXL Logo Generator) (logoai-replicate): ≈ $0.0372 per run (billed on GPU time)

• Ideogram v2 (ideogram-v2): $0.096 per image

• Recraft 20B SVG (recraft-20b-svg-replicate): $0.0528 per image

GPU-time prices are estimates; the run is settled on the real GPU seconds.

Same call, anonymous, free.

For developers

One API for every model

  • OpenAI-compatible: keep the OpenAI SDK and change the base URL.
  • One API key for chat, image, video, voice and more.
  • MCP server: agents search the catalog and, with an API key, run models.

FAQ

Questions about Railwail

Short answers. Prices and limits are on the pricing page, everything else in the docs.

Which models can I use?

Image, video, voice, music, chat and code models from the leading labs and from open-source teams. When a better model comes out, we add it, so you do not have to switch platforms. Every model has its own page with details and its price.

Can I try it without an account?

Yes. Every browser gets one free run on selected fast models (FLUX.1 [schnell], DeepSeek V4.1 Flash) in the console on this page. Video and voice models need an account.

How does pricing work?

Pay as you go: you top up a prepaid balance and each run is charged from it. There is no subscription, every model shows its price before you run it, and failed runs are refunded. Details are on the pricing page.

Can I chain models together?

Yes, with AI Flows: connect steps such as prompt, image and video, so the output of one model becomes the input of the next. Each step runs like a normal run.

Is there an API?

Yes, an OpenAI-compatible one: use the OpenAI SDK with the base URL https://railwail.com/api/v1 and your Railwail API key. Chat, images, speech, transcription and embeddings work like OpenAI's endpoints; video runs as a job that you poll.

Can AI agents use Railwail?

Yes, through the MCP server at https://railwail.com/api/mcp. Without a key it reads the catalog and the docs; with an API key, agents run models, billed like the API.
