What we built.
Quantx is a consumer AI agent for iPhone. Speak or type one task and Quantx plans the steps, drafts the messages, schedules the events, and pauses for approval before anything reaches another person. We partnered with the team end-to-end — brand, marketing website, native iOS app, agent loop, and the skill system that lets the agent safely act across Apple's native apps.

Nothing reaches another person without explicit OK
Why this was hard.
- 1
General-purpose chatbots can talk but can't actually do anything across your phone
- 2
Existing assistants either over-promise (and silently misfire) or under-deliver (and only answer questions)
- 3
Users need an agent that is bold enough to act and conservative enough to ask before sending
- 4
The product story has to be told in one phone screenshot — the marketing site is part of the product
How we shipped it.
01
One Command surface
Designed a single 'What should I handle for you today?' surface — voice, type, or tap a preset (Clear inbox, Plan my day, Draft reply). Everything else is one tap away.
02
Plan → Draft → Done
Built the agent loop around three visible states. Quantx plans the steps, drafts the artifacts (messages, events, replies), and only marks them Done after explicit approval for anything that reaches another person.
03
Skill system
Skills are scoped capabilities (Mail, Messages, Calendar, Reminders, Scan, Voice). Users see exactly which skills are wired in, and credits are surfaced inline ('3/3', '10/10', '5/5') so usage is never a surprise.
04
Safety as a feature
The agent runs safe steps automatically and asks before anything sends, books, or replies. 'Safely, and with you in control' is the marketing line because it's the product line.
05
Calm, cinematic brand
Deep purple-to-black gradients, oversized display type, and a hero shot of the actual app screen. The marketing site treats the phone as the hero — no clip-art robots, no AI clichés.
Features that shipped.
Voice or text intake
Start recording, type a task, or tap a preset — one surface for every input mode.
Plan / Draft / Done loop
Quantx plans the steps, drafts the artifacts, and waits for approval before sending.
Skill system
Scoped capabilities for Mail, Messages, Calendar, Reminders, Scan, and Voice — visible and toggleable.
Quick presets
One-tap presets like Clear inbox, Plan my day, and Draft reply for the most common jobs.
Scan or capture
Photo, video, or live scan inputs the agent can act on (extract, summarize, schedule).
Recent activity timeline
Every plan, draft, and action is logged so users can see and rerun what Quantx did.
Agent / Skills / Settings tabs
Native iOS tab bar separates the live Command surface from skill management and settings.
Free + Pro tier
Per-skill credit limits on Free, with a clear Pro upgrade surfaced inline ('Go Pro').
Marketing site
Designed and built the full marketing site — Features, Skills, Pricing, Blog — to match the app's calm brand.
"Envert delivered the whole product — brand, marketing site, and the iOS app. Quantx finally feels like a single thing, not a Frankenstein of vendors."
