The IDE extension handles context extraction — open units, [cursor](/en/tags/cursor/) position, compile errors, and the current project's unit dependency graph. That context gets compressed into a prompt and sent to a fine-tuned model that has seen a large chunk of Delphi open-source code and Stack Overflow answers. The result comes back as either inline completions or full refactor proposals, not just \"explain this code\" chat.\n\n## First Run, Step-by-Step\n\n1. Install the IDE plugin from the RAD Studio repository manager.\n\n2. Get an API key from the CodeBot dashboard (there's a free tier with 500 requests/day).\n\n3. Open the CodeBot panel, point it at your `.dproj`\n\nfile, and let it index for a minute or two.\n\n4. Hit `Alt+C`\n\nto generate at cursor, or `Alt+R`\n\nfor refactor suggestions on a selection.\n\nThe indexing stage is the important part. CodeBot builds a local semantic map of your units, so when you ask it to \"add error handling to this data module,\" it already knows which exception classes your project standardizes on.\n\n## A Real-World Prompt Workflow\n\nI spent an afternoon migrating a legacy forms app to a cleaner MVVM structure. The practical tutorial that worked best was giving CodeBot a single unit at a time and asking for concrete change sets, like this:\n\n```\nRefactor TCustomerForm in CustomerForm.pas to separate the business logic into a TCustomerViewModel class. Keep the VCL form as a thin view, preserve all existing event handlers' behavior, and use the currently injected TCustomerService from unit CustomerService.pas. Respond with the full new unit code plus a diff outline.\n```\n\nThe output wasn't perfect — the generated view-model had a duplicate property definition and one over-eager `Try`\n\nblock. But the diff outline made it easy to spot the mistakes. CodeBot also generated the unit tests in two seconds flat, something I usually skip because it takes too long by hand.\n\n## Honest Impressions After Real Use\n\n**Completion quality:** noticeably better than generic copilots on VCL and FMX code. It knows`TStringList`\n\nownership semantics and won't suggest leaks.**Refactoring:** the strongest feature. It respects the existing code style and unit boundaries.**Test generation:** baseline DUnitX tests are solid; edge-case coverage is still on you.**Slowpoints:** large multi-unit refactors can take up to a minute, and it occasionally pulls the wrong unit context if a project has duplicate filenames.**Deployment:** if you're behind a corporate firewall, you'll need the on-prem option — setup is straightforward but requires a separate server.\n\nThe real value isn't autocomplete. It's the ability to say \"turn this 400-line unit into a maintainable pattern\" and get a starting point that's 80% right. For a niche ecosystem like Delphi, that's a rare and welcome thing.\n\nIf you've been wondering whether AI can handle Object Pascal at all, CodeBot is the first answer that feels like it actually respects the language's constraints.\n\n[Next PISIGuard: Keep Your Private Data Out of AI Chat Logs →](/en/news/4833/)", "url": "https://wpnews.pro/news/codebot-for-delphi-a-deep-dive-into-the-new-ai-assistant", "canonical_source": "https://promptcube3.com/en/news/4835/", "published_at": "2026-08-03 10:13:34+00:00", "updated_at": "2026-08-03 10:27:25.662336+00:00", "lang": "en", "topics": ["artificial-intelligence", "developer-tools", "ai-products"], "entities": ["CodeBot", "Delphi", "RAD Studio", "VCL", "FMX", "DUnitX", "Object Pascal"], "alternates": {"html": "https://wpnews.pro/news/codebot-for-delphi-a-deep-dive-into-the-new-ai-assistant", "markdown": "https://wpnews.pro/news/codebot-for-delphi-a-deep-dive-into-the-new-ai-assistant.md", "text": "https://wpnews.pro/news/codebot-for-delphi-a-deep-dive-into-the-new-ai-assistant.txt", "jsonld": "https://wpnews.pro/news/codebot-for-delphi-a-deep-dive-into-the-new-ai-assistant.jsonld"}}
