Field note 07 / Platforms
Which fantasy platforms Knute supports (and which it does not)
ESPN is the only platform Knute connects to. Here is exactly what that covers, and what it does not.
The short answer
Which fantasy platforms does Knute support?
ESPN. Knute manages ESPN fantasy football and ESPN fantasy baseball teams today, and ESPN is its only platform integration. Yahoo, Sleeper, NFL.com, CBS Sports and Fantrax are not supported, and no date has been published for them. DraftKings and FanDuel are DFS and betting products, and Knute is not a betting tool.
I built Knute and run it on my own ESPN leagues. This note is the current answer.
01 / What supported means
What does Knute actually do on an ESPN league?
Supported means it acts on the team, inside limits you set. Here is what that covers.
-
01
Connect the league from the iPhone app
You sign in to ESPN from the Knute app. Connecting a league stores the session ESPN issues; that session lets Knute read your league and make moves on your team. It is encrypted at rest and never sent to a cloud model.
-
02
Read the roster, scoring and injuries
Knute syncs your roster and league settings, then reads the injury picture, the matchups and your league scoring before it decides anything.
-
03
Set lineups and work waivers
One pass a day, ahead of the slate, it sets the starters before the lock and swaps out a starter who is not playing. It sizes FAAB bids and priority claims to your roster and remaining budget, rejects a bid larger than what you have left, and can cancel a claim it already submitted.
-
04
Draft live in supported snake drafts
For supported ESPN fantasy football snake drafts, Knute watches the live room, makes the pick for your team and verifies the selection from the room event. It installs an ordered fallback queue before the room opens. Auction rooms are not supported.
-
05
Answer in chat and act when you say so
Separate from the daily pass, a chat agent answers questions about your team at any time and can make a move when you tell it to. Every move is logged, and the whole thing switches off in one tap.
You choose how much of that runs on its own, per league: Advisor proposes and waits for your approval, Co-pilot fires routine moves and flags the bigger calls, Autopilot runs the team inside limits you define.
02 / Requirements
What does an ESPN user need?
Two things. An ESPN fantasy account with a football or baseball team in a league that has already been created, and an iPhone with the Knute app from the U.S. App Store. New Knute accounts use email and password signup and must verify the email address.
Ordinary product features are free. Three optional one-time App Store credit packs fund third-party cloud-model usage. Your ESPN login is never sent to a model provider.
03 / Platform by platform
Which platforms work today?
This table is the whole answer. If a platform is not marked supported here, Knute cannot read it or write to it.
| Platform | Supported today | What works |
|---|---|---|
| ESPN fantasy football | Yes | Lineups, waivers and FAAB, injury pivots, supported live snake drafts, chat. |
| ESPN fantasy baseball | Yes | Daily lineups, waivers and FAAB, injury pivots, chat. No live draft workflow. |
| Yahoo Fantasy | No | Nothing. Not built; no published date. |
| Sleeper | No | Nothing. Not built; no published date. |
| NFL.com Fantasy | No | Nothing. Not built; no published date. |
| CBS Sports Fantasy | No | Nothing. Not built; no published date. |
| Fantrax | No | Nothing. Not built; no published date. |
| DraftKings, FanDuel | No | Nothing. DFS and betting products; out of scope by design. |
04 / The honest answer on everyone else
Why only ESPN?
One person built this, and I would rather ship one platform that acts than five that advise. Every job above depends on a write path the platform accepts: a lineup change that sticks, a waiver claim the site records, a draft pick the room confirms. I built that path for ESPN and nowhere else.
Yahoo, Sleeper, NFL.com, CBS Sports and Fantrax are platforms I would like Knute to manage. None of them is connected today, and I have not published a date. Older pages on this site said otherwise; they are no longer part of what the site presents, and this note supersedes them.
DraftKings and FanDuel are a different question: daily fantasy contests and sportsbooks, not season-long leagues. Knute manages a roster over a season where the league lives. It does not build DFS entries, price contests, or place or recommend bets.
05 / Limits
What Knute does not do
It never makes trades. Multi-team transactions are refused at the same gate that permits lineups, adds, drops and waiver claims, so there is no setting that turns them on. The live draft workflow does not join auction rooms. It does not connect to any platform other than ESPN, and it does not manage basketball, hockey or soccer teams.
It runs one autonomous pass a day, ahead of the slate. There is no continuous intraday watch, so a midday scratch is not picked up until the next pass unless you open the chat and ask.
06 / Questions people ask
Platform questions, answered plainly
-
01
Does Knute work with Yahoo Fantasy?
No. Knute does not connect to Yahoo Fantasy today. ESPN is the only platform integration. I have not published a date for Yahoo support, so treat any page that says otherwise as out of date.
-
02
Does Knute work with Sleeper?
No. Knute does not connect to Sleeper leagues today, in redraft, dynasty or best ball. ESPN fantasy football and ESPN fantasy baseball are the only leagues it can manage, and there is no published date for Sleeper.
-
03
Does Knute work with NFL.com, CBS Sports or Fantrax?
No. None of the three is supported today. Knute has one platform integration, ESPN, and every other host is unbuilt. If your league lives on NFL.com, CBS or Fantrax, Knute cannot read it or make moves on it.
-
04
Does Knute work with DraftKings or FanDuel?
No. DraftKings and FanDuel are daily fantasy and betting products. Knute is a season-long league manager for ESPN, not a DFS optimizer and not a betting tool. It does not build DFS lineups, price contests or place wagers.
-
05
Can an AI connect to my ESPN fantasy league?
Yes. Knute connects to ESPN fantasy football and ESPN fantasy baseball leagues from its iPhone app. Once connected it reads your roster, scoring and the injury picture, sets lineups, works waivers, runs supported live snake drafts and answers questions in chat, at the autonomy level you choose.
If your league is on ESPN
Connect it and hand over the daily work.
Get Knute on iPhone, connect your ESPN football or baseball team, and keep the autonomy level and the stop button. If your league lives anywhere else, I would rather tell you now.
