# Workbench
> Drop a file, add a line of steps, press Run. How batching, sets, and credits work on the bench.
The Workbench is the signed-in editor at [mediamonster.app/workbench](https://mediamonster.app/workbench). The landing page is the same dropzone for guests; signed-in visitors are sent here. On a phone the tab is **Bench**.
Nothing runs until you press **Run**.
## Start a line
Drop files, paste a URL, or open:
* a Vault asset with `?asset=`
* a recipe with `?recipe=`
* a Queue job with `?job=`
* a trend with `?trend=`
Add steps from the picker. Drawers are **Make**, **Fix**, **Change**, **Describe**, and **Finish**. **Popular** is a shelf, not a drawer.
Browser page steps sit alongside skills:
| Step | What it does |
| -------------------------- | ------------------------------------------ |
| **Save as** | Convert the file (the `convert` page step) |
| **Resize** | Change size or aspect |
| **Adjust** | Colour and exposure in the tab |
| **Put it on a background** | Compose (`compose`) |
| **File it in the Vault** | Store the result (`route`) |
## How a line works
A line carries **one file**. Every step is handed what the step above made.
Whether a skill can sit under another is computed from the catalogue — not from the drawer they share. A step that hands back pictures cannot feed a skill that needs speech.
Some skills keep the kind of file they were given (`captions`, `clean-audio`, `remove-silences`). Read that as "the line still carries a video if you handed it a video."
Per-minute skills bill the length the line is carrying, rounded up to a whole minute with a one-minute floor. If a step changes the length and does not say what it made, the next per-minute step bills that floor.
## Sets
These skills hand back several files:
* Clips
* Video splitter
* YouTube thumbnail
* Video Multiplier
* Graphic Multiplier
Every step below a set runs once on **each** file. **Two sets in one line are refused.**
Browser-only steps cannot sit under a set that still has steps after it — that fan-out only runs on the server.
## Batching
Plan batch sizes are a **browser** ceiling. Each file is its own run. Credits bound the bill, not the batch control.
| Plan | AI files at once | Free-tool files at once |
| -------- | ---------------- | ----------------------- |
| Cyclops | 1 | 5 |
| Minotaur | 50 | 500 |
| Kraken | 1,000 | Unlimited |
| Behemoth | 5,000 | Unlimited |
## What runs where
A line that includes a skill, or that generates its own file, runs **on the server**. It finishes if you close the tab.
A browser-only line — compose, resize, adjust, Save as on images — stays in the tab.
Poll ceilings: about 6 minutes for an ordinary run, 20 minutes for a set, a slow skill, or a per-minute skill.
## Credits on the bench
Credits come off before the provider is called and are refunded if that step fails. The plan's **AI steps per run** counts only steps that spend credits. Free tools do not count. The absolute ceiling is 60 steps.
An empty prompt is refused **before** a credit moves, if the skill needs one. Prompts are capped at 2,000 characters.
See [Credits and plans](/getting-started/credits-and-plans) and [Limits](/help/limits).
## Save the line
**Save as a recipe** keeps the steps (not a backdrop from your own files). Plan caps: Cyclops 3, Minotaur 25, Kraken and Behemoth unlimited.
