The builder has two halves: the Design assistant on the left and a live preview on the right.
Talk to the assistant
Describe what you want in plain words, then refine:
- "Build a page for RevOps leaders. Lead with their company, then a custom idea for their outbound, then proof, then pricing and a booking button."
- "Make the hero shorter and use {{industry}} in the subtitle."
- "Mark each part of the page as a tracked section."
Each reply shows the model, the time it took and its cost. The line under the chat shows what this design has cost so far and roughly what the next change will cost. All of it is charged by your AI provider on your key.
Pick a model
The model picker lists the models available on your keys, grouped by provider. A provider without a key shows as no key connected. If you do not pick one, Echo uses a strong default.
Mention parts with @
Type @ in the chat to point at something precisely:
- Sections, for example
@Pricing - Data fields, inserted as
{{company}} - AI parts, for example
@ai:custom_idea
Use the arrow keys and Enter to pick.
Attach files and links
- Attach (or drag files onto the chat) adds images, PDFs, slides, docs or spreadsheets as context. Images are shown to the model. Large photos are resized automatically.
- Paste up to three public links in a message and the assistant reads them, for example your case study page.
- Uploads count toward your plan's storage. Videos are not on the Free plan; paste a Loom, YouTube or Vimeo link instead.
Preview
Switch between desktop and mobile, and turn Slots on to outline every part that changes per lead.
Limits
To keep costs predictable: about 30 messages per 10 minutes per person, messages under 6,000 characters, and the last 12 turns are remembered.
