Half of architecture enquiries don't have planning, budget, or a buildable site. The other half don't understand the difference between a Stages 1-4 appointment and a full RIBA Stages 1-7 service, and 'cost per square foot' is the question that derails the most chemistry calls. Generic chatbots quote random numbers and route everyone to the same form, leaving the principal architect to filter dreamers from doers in the first ten minutes of every call.

SleekAI uses your own service pages and RIBA stage descriptions to qualify enquiries before a call. A Crouch End Edwardian with a side-return, rear extension, and loft becomes a real conversation: 9-12% of build cost for full Stages 1-7, 5-7% for Stages 1-4 only, build costs at 3,200-4,200 GBP per square metre for the area, recommended structural engineers and party wall surveyors named. It checks site address against published conservation area notes, references real projects in similar typologies, and books a chemistry call with site address, scope, and budget already attached.

The principal architect's hour is spent with clients who have planning ambitions, a buildable site, and a budget bracket that reflects the area. Multibot lets a residential bot run on /houses with one tone and a commercial bot run on /workplace with another. NDA project work and unpublished case studies stay invisible. The chemistry call opens with a real brief, not 'tell me about your site'.

Architecture practices sell senior judgement, and the chemistry call is where the relationship is won or lost. A practice principal spending 30 minutes with a client who hasn't worked out whether they want planning-only or full service is half an hour of margin gone, and clients who turn up without understanding RIBA stages tend to balk at the proposal a week later when they realise Stage 5 onwards is a separate appointment. Stage-aware chat closes that gap.

The client arrives at the chemistry call understanding that 9-12% for full service buys all seven stages, that Stages 1-4 ends with a tender-ready package, and that the practice's recommended structural engineers and party wall surveyors are named for a reason. They also arrive with a realistic build cost bracket that reflects the area — Crouch End Edwardians at 3,200-4,200 GBP per square metre — rather than a number from a national 'cost per square foot' calculator. Multibot lets the practice run a different tone and qualifying flow on the residential side versus the workplace or commercial side, and display conditions keep press and trade visitors out of the residential funnel entirely.

The chemistry call becomes a chemistry call, not a service explainer.
