Capture an architecture review while it is happening
Wavelength is a voice to diagram tool for solution architects. You talk through a design, it draws the flow, and the review ends with an editable diagram instead of a photo of a whiteboard that nobody opens again.
Let me be direct about scope first, because it will save you a click. This is not an architecture documentation tool. It does not do C4, UML, or BPMN 2.0. If you are maintaining a living model of a system, IcePanel, Structurizr, Eraser, and Lucidchart are all better at that than this will ever be.
What this is for is the hour before any of that exists.
The demo needs no account. The free plan needs no card.
The gap between the conversation and the artifact
Architecture gets decided in conversation. Somebody proposes routing writes through a queue, somebody else points out the ordering guarantee that breaks, a third person suggests a compromise, and by the end of the hour the group has genuinely converged on something.
Then everyone leaves, and the only record is a whiteboard photo and four sets of notes that disagree. The person who volunteered to "write it up" does so three days later from memory, and what gets written up is their reading of the room rather than the room's actual conclusion.
The design was real. The artifact is a reconstruction. The gap between them is where rework comes from.
What changes
- Run it during the discussion. Wavelength structures the flow as people describe it, so the facilitator does not have to choose between participating and documenting.
- Put it on the screen once there is shape to it. The moment a group can see the thing they have been describing separately, disagreements surface that would otherwise stay buried until implementation.
- Read the dashed amber lines out loud before you close. Those are the connections Wavelength inferred rather than heard. In a design review that is frequently a precise list of what the group assumed but never actually said.
- Leave with something editable. Export a PNG, share a link, or hand the flow to whoever is producing the formal documentation as their starting point.
The dashed lines are the agenda for the last five minutes
Most review artifacts look equally confident about every element on them, which hides the difference between "we agreed this" and "we all quietly assumed this." Rendering inferred connections differently turns that distinction into something you can point at and resolve while the group is still in the room.
Where this sits next to your existing tools
| Stage | Right tool |
|---|---|
| Understanding an existing system somebody is explaining to you | Wavelength |
| Capturing a design as it is argued out in a review | Wavelength |
| Maintained C4 model of a system over time | IcePanel, Structurizr |
| Architecture diagrams in a repo alongside code | Mermaid, PlantUML, Eraser |
| Formal UML, ERDs, BPMN 2.0, network topology | Visio, Lucidchart |
| Cloud reference architecture for a proposal deck | Lucidchart, or your cloud vendor's icon set |
The honest framing is that Wavelength produces the input to those tools rather than competing with them. It gets the messy shared understanding out of the room and into something structured fast enough that it still resembles what was actually decided.
The async version
Not every review is live. If the session was recorded, paste the transcript afterward and you get the same diagram. That also covers the case where you were the one presenting and could not drive a canvas at the same time. See turning a transcript into a flowchart.
Common questions
Does this replace IcePanel or Structurizr?
No. Those maintain a model over time with formal notation. This captures a conversation. Different jobs, and the output of this one feeds the other.
Can it produce C4 or UML?
No. Process and data flow only: actors, systems, decisions, data stores.
How do I capture a design discussion without stopping to draw?
Run it live during the discussion, or record and paste the transcript afterward.
What if the diagram is wrong?
Inferred connections show as dashed amber so you can see exactly what to verify. Edit by typing an instruction, right-clicking, or by hand.
Does my team get a shared library?
On Pro: pre-configured teams, a shared flow library, and per-flow collaborators. See pricing.
