Workflows · the long version

Workflows from
the chats that
worked.

The best workflows are discovered, not designed. You go back and forth in chat — running code, searching the web, trying different models — until you get the answer you actually wanted. Then you say "save this and run it every morning." Catalyst turns that exact sequence into something it can repeat the same way every time. No diagrams, no setup — it just remembers what worked.

The Catalyst workflow editor: a multi-model stock-research pipeline fanning out to three models and synthesizing one verified answer

The actual editor — input → research → three models in parallel → synthesize → output. Drag to compose, or let the chat author it for you.

The loop

Chat. Save. Schedule.

01

Figure it out in chat.

Ask, run a little code, search the web, switch models — whatever it takes. Keep tweaking until you get the answer you actually wanted. Chat is your scratch pad: fast, cheap, no commitment.

02

"Save this as a workflow."

Just ask. Catalyst takes the steps that worked and writes them up as a workflow it can run again — automatically. There's nothing new to learn, and you never leave the chat.

03

Try it before you save.

The workflow opens in a live editor right next to the chat. Run it as many times as you want before committing to anything. Adjust it by asking in plain language, or drag the steps around by hand.

04

Schedule it. Get the email.

Pick a time and your time zone. Have it email you the result — reports, spreadsheets, whatever it made — with the files attached. Catalyst runs it on schedule, even while you sleep.

Building blocks

Ten simple pieces. One workflow.

A handful of pieces snap together. Most workflows use just four of them — but they combine into just about anything you can think of.

start

input

The values you feed in — like a list of stock tickers. Set defaults so it can just run on its own.

finish

output

What the workflow hands back when it's done — the report, the answer, the file.

ask a model

llm

Pick a model, write the prompt. Swap to a different model anytime without rebuilding anything.

run code

python

Run a snippet of code in a clean, private workspace. Anything it makes — a chart, a PDF — gets picked up automatically and passed along.

build text

template

Stitch results together into a message or prompt. Misspell the name of an earlier step and it stops and tells you — instead of quietly sending something broken.

use a tool

tool

Send an email, search the web, generate an image, fetch a page — any of the tools Catalyst connects to.

choose a path

condition

Go one way or another depending on what happened. The two paths can rejoin later.

repeat

loop

Run the same steps over a whole list — every ticker, every row — many at the same time.

call a service

http

Send data to another app or service. (To just read a web page, the fetch tool is easier.)

reuse

workflow

Drop a whole saved workflow in as a single step. Build big things out of smaller ones.

How it runs

Something that doesn't lie to you.

Plenty of tools quietly hide their mistakes and hand you a broken result anyway. Catalyst is built to fail out loud, stay tidy, and run the same way every time.

no silent typos

A typo stops the run.

Misspell the name of an earlier step and it won't quietly send you an empty, broken result. It stops right there and tells you what went wrong — and what the correct names are.

no snowball

One failure doesn't spread.

If a step fails, everything that depended on it is skipped and shown in gray — instead of wasting your time and money running on bad data.

clean every time

Each run starts fresh.

Every run gets its own private workspace, so runs never trip over each other. Any files it creates are saved automatically and passed straight to the next step.

try first

Run before you save.

Test a draft as many times as you like before committing to it. Every run still shows up in your history, so nothing gets lost.

all at once

Do a whole list in parallel.

Process every item — all your tickers, all your rows — at the same time instead of one by one. If a few fail, the rest still come through.

build from blocks

Workflows stack.

Use a saved workflow inside another one as a single step. Build big, reliable automations out of smaller pieces you already trust.

automation

Set it. Forget it.
The inbox does the rest.

Pick when it should run and your time zone. Catalyst runs it on its own and emails you the result — as a nicely formatted message with any files attached. You'll see it land in your inbox; you don't have to be sitting there for it.

  • Any time, any time zone. Set the schedule and we describe it back to you in plain English.
  • Bring your own files. Upload a spreadsheet once, and every run gets its own copy to work from.
  • Email built in. Send formatted messages with attachments — no extra setup, no plumbing.
  • See every run. A clear history of what ran, when, and what it produced, with a live countdown to the next one.

full visibility

Every run, every step, visible.

Watch each step finish in real time. When it's done, every step's inputs, results, and files are saved — so you can open any past run and see exactly what happened. No digging through logs, no guesswork.

  • Live updates. Watch each step as it runs — what it found, what it made, where it stopped.
  • Full history. Every run is saved exactly as it ran — quick draft, manual run, or scheduled.
  • See the files. Images show up right inline; web pages open in a new tab.
  • Team view. Admins can see everyone's scheduled runs, the last few results each, and a countdown to the next.
