The AEC expert that
already knows your site.
Atlas AI is a free, specialist AI built for urban designers, architects, and planners. Unlike ChatGPT, it knows your site, remembers your project, and speaks fluent planning policy.
Generic AI doesn't know
what a sequential test is.
The Generalist Problem
You ask ChatGPT about planning policy. It gives you a generic answer about "checking with local authorities." You already know that.
The Tool-Switching Problem
You switch between the planning portal, flood risk maps, Google, Excel, and Word — for every single project. None of them talk to each other.
The Memory Problem
Every conversation starts from zero. You re-explain your site, your pre-app feedback, your client's requirements — every single time.
Atlas AI solves all three.
It knows UK planning policy, it pulls live data from real sources, and it remembers everything about your project.
Built for AEC. Not adapted for it.
It already knows your site
Connect your Atlasly project and Atlas AI is instantly briefed — site area, planning zone, flood risk, PTAL score, local authority. You never have to describe your site again.
Planning references with source checks
Explore the NPPF for England, the London Plan and design guidance. Review the cited edition, local context and source text before using a policy reference in a proposal.
It remembers what matters
Pre-app advice, client requirements, planning constraints, scheme parameters — pin them once and Atlas AI references them in every conversation, automatically.
Diagrams and calculations, not just words
Ask for a street cross-section and get one. Ask for a density calculation and get an interactive tool. Ask to compare three FAR scenarios and see them drawn.
What Atlas AI can actually do
Select a capability to see a real example.
The sequential test applies whenever development is proposed in flood risk areas — specifically Flood Zones 2 or 3, or land with a 1-in-100 or greater annual probability of flooding.
What the sequential test requires
Under NPPF Chapter 14 (paragraphs 167–172), applicants must demonstrate that:
The Exception Test (FZ3 only)
Two limbs must both be satisfied:
Practical implications
From site acquisition to planning submission. Atlas AI is there for all of it.
Feasibility
Instant site briefing from a postcode. Planning history, flood risk, PTAL, comparable schemes — in 60 seconds.
Pre-Application
Understand what the LPA will say before you book the pre-app meeting. What policies apply. What questions to ask. What to design for.
Design Development
Density targets, daylight checks, parking calculations, sustainability scoring — all in the chat, with your site's actual parameters.
Planning Application
Policy research, comparable consented schemes, and document drafting. Planning statements in minutes, not days.
Condition Discharge
Upload your decision notice. Atlas AI extracts every condition, categorises them, and tracks what needs to be discharged before commencement.
Built on the depth the industry runs on
Built for every AEC professional
Urban Designer
From density studies to masterplan feasibility. Atlas AI knows your design standards — Gehl, NACTO, BRE — and applies them to your specific site.
Architect
RIBA stage checklists, planning policy interpretation, daylight analysis, BIM guidance. The expert colleague who never sleeps.
Town Planner
Appeal decisions, comparable schemes, local plan policy, viability sense-checks. Deep research in minutes, not days.
Architecture Student
Free, always. Learn planning policy as you design. Get feedback on your schemes against real standards. Build the knowledge that takes practitioners years to acquire.
Atlas AI is free.
No credit card. No time limit. No watered-down trial.
Free users get full access to the AEC knowledge engine, live data tools, diagrams, and calculators. Project memory and advanced features unlock when you're ready.
Taking a site forward as a project?
Atlasly Developments keeps each project’s parcels, evidence, options, appraisal, actions and packs together. It shares your Atlas AI projects.
Questions
Yes. The core Atlas AI chat — planning policy, live data, diagrams, calculators — is free for everyone. No credit card required. We want every architect, student, and planner to have access to expert AEC knowledge.
ChatGPT is a brilliant generalist. It will answer planning questions, but it doesn't know what site you're looking at, it can't look up real flood risk or planning history data, it has no memory of your project, and it has no idea what the local planning officer in your borough is likely to say. Atlas AI is specific to your project in a way a generic AI is structurally incapable of being.
Planning references include the NPPF for England, the London Plan, local plans and design guidance. Coverage varies by source. Check the edition and applicability of each returned extract against current official publications before relying on it.
Currently optimised for UK planning — particularly England and the London Plan. We're expanding to Scotland, Wales, and international jurisdictions. If you're working outside the UK, Atlas AI will flag this and apply international standards where possible.
Planning application history (via DLUHC Planning Data API), flood risk zones (Environment Agency), nearby amenities and street data (OpenStreetMap), site elevation, and address context — all for any location in England.
Yes. Your project memory, conversations, and site data are private to your account and never used to train AI models or shared with other users.
