Manchester software house. We build websites, web and mobile apps, MVPs and AI for UK businesses.
Prospective clients contact several firms and instruct the one that responds first and clearly. We build AI intake chatbots, phone agents and document automations for UK law firms, designed around confidentiality, conflict checks and human review. BigBerri also builds Writford, an AI legal research platform, so we understand how solicitors work.
Web and phone enquiries outside office hours go unanswered and instruct elsewhere.
Qualified solicitors spend billable time on initial questions a structured intake could capture.
Conveyancing and litigation clients call for progress updates that could be answered automatically.
Engagement letters, ID checks and bundles are assembled by hand every time.
Captures matter details, runs conflict-check questions, explains fee structures and books consultations, never giving legal advice.
AI Chatbot Development pricing and detailsAnswers calls 24/7, routes by practice area, takes secure messages and books appointments with the right fee-earner.
AI Voice Agents pricing and detailsGenerates engagement letters, chases ID and documents, and sends milestone updates from your case management system.
AI Automation pricing and detailsConnects to Clio, LEAP, Actionstep, Proclaim or your system with role-based access and full audit trails.
AI Integration pricing and detailsNo. It is configured to gather information, explain process and fees, and book a consultation. It declines to advise and routes anything sensitive to a person. You review and approve every script.
Conversations are encrypted, stored in the UK or EU under a data processing agreement, and retained only as long as you specify. We document the setup to support your DPIA and discussions with your COLP.
Yes for the main UK systems with APIs. Where an API is limited, we use secure email or form handoffs so nothing is re-keyed.
Fixed price after a free discovery call. A booking and FAQ bot is the smallest scope; an intake bot that writes into your case management system and handles conflict-check questions is a larger one. Phone agents and automation workflows are quoted separately so you can start with one.
Tidio, Intercom and Chatbase offer AI chatbots on published monthly plans; custom-built chatbots avoid per-resolution fees entirely. An honest comparison of which route actually suits a UK business.
What a custom AI chatbot costs in the UK, how long it takes to build, what it actually does that a scripted bot could not, and how to choose a developer.
What actually drives AI development cost in the UK for chatbots, voice agents, automation, integration, web apps, mobile apps and MVPs — plus offshore comparisons and the questions to ask before you sign a quote.

Explore Let AI BrowseRead the LetAIBrowse case studyThirty minutes, free, no obligation and no salesperson. You describe what is costing you time or customers, we ask about the systems involved, and you leave with an honest view of whether this is worth doing. We regularly end that call by saying the tool you already pay for covers it.
The code, the repository and the accounts are set up in your company name rather than ours, and they are yours on completion and full payment. Nothing runs on infrastructure we control, so ending the relationship does not end the thing we built.
Every project is quoted as a fixed price with a written scope after the call, so an over-run is our problem rather than yours. If the scope changes, we say so and re-quote before doing the work, not after.
In the UK or EU, under a data processing agreement, kept only as long as you specify. Any model provider we rely on is named as a sub-processor rather than left implicit, and we will tell you plainly where something you have asked for would put a commitment of yours at risk.
Agreed before launch rather than negotiated during an incident: what is covered, how quickly we respond, and what counts as new work. Every build has a defined escalation to a person, because the failure that costs you is the one nobody noticed.
