        "longDescription": "ONYST RVG connects ChatGPT to the fee engine behind the ONYST fee calculator for German lawyers. ChatGPT no longer estimates fees under the German Lawyers' Remuneration Act (RVG): it asks the engine, and every item comes back with its fee number (VV), rate and calculation.\n\nWhat you can do:\n- Calculate fees, expenses and VAT for a matter, or for several matters with credits between them, for example a payment order procedure followed by a lawsuit.\n- Determine the value in dispute, for example for tenancy, maintenance or dismissal cases.\n- Look up fee numbers, rates and required inputs in the fee schedule.\n- Find the route between two addresses for travel expenses, with a map and the distance as an expense item.\n- See an invoice as a draft in your firm's layout, then issue it as PDF or e-invoice (ZUGFeRD), along with a calculation sheet. Documents arrive as a download link that is valid for seven days.\n- Find recipients in your address book and read or update your firm's invoice details. ChatGPT asks before every change.\n\nResults appear as interactive views in the chat: the calculation, the value in dispute, the fee schedule, the route, the invoice draft with its pages, the finished invoice and the documents to download.\n\nWho it is for: law firms and legal departments in Germany. You sign in with your ONYST account; new users can create one during sign-in. The calculation tools work with every ONYST account. Whether invoices, calculation sheets and the distance for travel expenses are available depends on your firm's ONYST account.\n\nLimitations: ONYST RVG calculates lawyers' fees under the RVG; it does not calculate court fees. The results are a calculation, not legal advice. Whether a fee applies in the individual case and whether a discretionary rate is appropriate remains the lawyer's responsibility.\n\nYour control: every connected assistant is listed in your ONYST account under Connected assistants and can be disconnected there at any time. Download links can be withdrawn in the invoice history.",
