How to use the Experiment plan template

Start a board from it
Use this template opens a new Freero board with the Experiment plan template on it (sign up free first). On a board you already have, open Templates in the toolbar and search for “Experiment plan”.
Follow the instruction on the board
“Decide what result would change your mind before you see any data. If no result would change the plan, skip the experiment.”
Fill in each part
- We believe The assumption under test, in one sentence.
- So we will The smallest test that could prove us wrong.
- We’ll know by Which number, how big a change, by when?
- Guardrails What must not get worse while we test?
- If it works What do we do next if the signal is clear?
- If it doesn’t What do we do if it’s flat or negative?
Bring your team and your agents
Invite people to the board or share a link, and work on it together live. The timer is in the top bar, private mode and voting in the board menu, and Claude or ChatGPT can join through Freero’s MCP server.

Work on it with an AI agent

Connect an assistant once and it works on the board with you, with your permissions: by default it reads and proposes, and people decide.

You ask: “Fill in the Experiment plan board from these notes.”
What happens It reads the board, then proposes sticky notes for it. Nothing changes until someone on the board accepts them.
You ask: “Group what we wrote into themes and list the actions.”
What happens It proposes clusters with a title each and task cards for the actions, labelled with its name and yours.

Idea to experiment
Turn one promising idea into a small, honest test: the belief behind it, the test, the signal to watch and the decision it informs.
Assumption test plan
For each risky assumption behind a plan: how we will test it, what we will measure, where the pass line is and what we found.
A/B test readout
Share the result of a finished A/B test: what changed, what happened to the main and guardrail metrics, and what you decide.
Discovery sprint plan
Plan two to four weeks of discovery: frame the question, learn from customers, generate options, test them and decide.
Assumption map
Sort what you believe about an idea by how much it matters and how much evidence you have, then test the risky ones first.
Hypothesis tracker
Keep every working hypothesis in one table with the evidence for and against, how confident you are and the next test.
