Getting started
Create a project at buildwitharchie.com with an address and a short description of what you're building or renovating. From there, Archie starts tracking it — tasks, budget, timeline, contacts — as the project moves forward.
You don't have to enter everything by hand. Forward an email thread, message Archie on WhatsApp, or upload a document, and Archie reads it and keeps the project record current.
Cost estimates
Tell Archie what you're building — a project type and address, a square footage, or just a plain-English description like "finish my basement into a one-bedroom with a bath" — and it returns a construction cost estimate as a low–mid–high range, broken down phase by phase, along with a rough timeline and the permits you'll likely need.
You don't have to speak in construction terms. Archie reads a free-text description, classifies it into real, priced scopes of work, and tells you how confident it is. It also adjusts for how the work gets done — general contractor, owner-builder, or DIY all price differently.
Estimates come from a real pricebook — dozens of project types priced by region and finish level. It's a planning number to help you budget and talk to contractors, not a contractor's fixed bid.
Budget tracking
Every project has a live budget organized by construction phase. Each line item tracks the original forecast, the accepted bid, the expenses you've actually paid, and any change orders — so you always know what's spent to date and what's left against your budget.
When a contractor quote comes in — over email, WhatsApp, or chat — Archie logs it as a bid for your review. A quote never silently changes your forecast; you approve it first. Your budget lives in one place, and you can share a clean budget page with your GC or lender.
Timeline & phases
Archie builds a schedule of construction phases with durations, start and finish dates, and the tasks that belong under each phase. You set the start date and your target finish; the phase durations come from the scope of work.
As real life happens, you can anchor the schedule to actual events — "the GC starts demo on July 1" — and Archie recalculates the dates and which phase you're currently in. There's a shareable timeline view so everyone on the project sees the same plan.
Tasks
Tasks are to-dos with an assignee, due date, priority, and status (backlog, to-do, in progress, done, or cancelled), shown on a board in your dashboard. Each task lives under a timeline phase, so the plan and the work stay connected.
Create tasks by hand, ask for them in chat or WhatsApp, or let Archie pull them out of an email automatically. Tasks Archie finds on its own go to your review queue before they land on the board — the rule of thumb is simple: if it's something a person has to go do in the real world, it's a task.
Permits
Give Archie an address and a scope of work and it identifies which permits you're likely to need, who your local building department is, the typical timeline and fees, and the next steps to take — tracked on a Permits tab you can update as each one moves along.
For New York City, Archie goes deeper: it distinguishes alteration types (ALT-1, ALT-2, ALT-3), points you to the right DOB NOW portal, and includes step-by-step filing guides. It's honest about certainty, too — it flags when permit info is confirmed for your city versus a typical default, and never presents an unverified list as gospel.
Your permit package is in with NYC Department of Buildings.
Typical plan-check timeline here is: Professionally certified ALT2 filings clear quickly; LL149 (HPD harassment list) forces Standard Plan Examination, which adds plan-exam time. TPP, Site Safety, and any LPC review add time on top.
Archie identifies and tracks your permits and links you to the right portal — it doesn't file them for you. Its coverage grows city by city as new jurisdictions come up.
More tools
Beyond the core project workspace, Archie includes a set of focused tools — also available as free calculators on the site:
Home Value Forecast estimates a property's after-repair
value for different renovation scopes, showing the value each one adds
and how much of the cost it recoups. It's a market analysis, not an
appraisal.
Inspection Prep reads a home-inspection report and
sorts the findings by urgency — fix now, within six months, within a
year, or defer — with a cost range for each.
Investment Strategy Planner compares renovation
strategies for a property and ranks them by return.
Feasibility, zoning, and building-code lookups tell you
what you can build on a given lot and the rules that apply.
CC or forward any project-related email to Archie — a contractor bid, a permit update, a scheduling change. Archie reads the thread, extracts what matters, and replies in-thread when a reply is useful.
Archie participates like any other person on the thread — it doesn't require a special subject line or format.
Add Archie to the WhatsApp group your crew already uses. Ask it anything about the project — budget status, permit timing, what a contractor already committed to — and it answers from your project's own history, not generic advice.
See it answer three real questions in the WhatsApp walkthrough, or add Archie to your group directly.
The agent & its tools
Archie isn't a form or a set of buttons — it's an AI agent. When you send a message or a document, it works out what you're actually asking and reaches for the right tool: pulling numbers from your project record, searching your past emails and documents, running an estimate, checking permits or zoning, looking up a product or company on the web, drafting a reply, or creating a calendar invite.
Answers are grounded in your project's own history — what a contractor committed to, what's in the budget, what's outstanding — not generic advice. And it works the same whether you reach it by email, WhatsApp, or the dashboard.
As it reads what you send, Archie also organizes it — sorting details into budget, tasks, timeline, contacts, vendors, permits, and more, so your project record stays current without manual data entry.
Data & approvals
When Archie extracts something from an email, document, or message — a budget change, a new task, a vendor's contact info — it doesn't get saved to your project automatically. It goes into a pending-approvals queue first, so you always see and confirm what's about to change before it becomes part of the record.
Low-risk details like a new contact save on their own; the things that matter most — budget, tasks, timeline, vendors, change orders — wait for your review in the dashboard's "Needs your review" area. When you tell Archie a value directly and confirm it, you're the approver, so it saves straight away.
FAQ
Is Archie a new app I have to install?
No. Archie works inside channels you already use — email and WhatsApp — plus a dashboard if you want one. There's nothing new to install for your contractor, designer, or family to use.
Does Archie save data to my project without asking?
No. Anything Archie extracts from an email, document, or message goes into a pending-approvals queue first. It only becomes part of your project record after you approve it.
What can I ask Archie over WhatsApp?
Anything about your project's history: budget status, permit and inspection timing, what a contractor already committed to, or what's outstanding. Archie answers using your project's own record, not generic advice.
Can I remove Archie from a WhatsApp group later?
Yes — Archie is a regular participant in the group, so removing it works the same as removing anyone else.
How accurate are Archie's cost estimates?
Estimates are planning ranges drawn from a real pricebook, adjusted for your region, finish level, and who's doing the work. They're meant to help you set a budget and have grounded conversations with contractors — not to replace a contractor's firm bid.
Does Archie file my permits for me?
No. Archie tells you which permits you likely need, who your local building department is, the typical timeline and fees, and the next steps — and links you to the right portal (like DOB NOW in NYC). The actual filing is still done by you or your team.
