Why IgeraGestories is not just another ChatGPT
Zero legal hallucinations
IgeraGestories uses RAG (Retrieval-Augmented Generation) over real indexed legislation, not training memory. It only responds from documents that exist in your knowledge base. If an article is not indexed, it says so explicitly rather than inventing one.
Your documents, your context
Upload your own collective agreements, AEAT circulars, internal procedures and regional (foral) legislation. IgeraGestories answers combining public law with your own documents, all with full source traceability.
GDPR guaranteed from day 1
Client tax data never leaves the multi-tenant environment. Exclusive EU-server processing under Art. 28 GDPR. Signed DPA included. AEPD fines for improper use of ChatGPT with client data can reach 2% of global turnover.
FAQ — ChatGPT alternative for Spanish tax firms
Can ChatGPT make mistakes in Spanish tax law?
Yes. ChatGPT is a language model with a knowledge cutoff that does not access the BOE (Official State Gazette) in real time. Tests performed by Spanish tax firms have confirmed hallucinations in LIRPF articles, VAT rates and filing deadlines. The model can also mix Spanish tax law with the legislation of other Spanish-speaking countries without distinguishing them.
Can I use ChatGPT safely with my client data?
Not safely. OpenAI's terms of service allow the use of data submitted to improve their models unless the user explicitly opts out. Entering client tax data (NIF, income, deductions, assets) into ChatGPT may constitute an infringement of Art. 28 GDPR, since OpenAI does not act as an approved data processor under European data protection law.
How does IgeraGestories compare in price to ChatGPT Plus?
ChatGPT Plus costs around €20/month but without Spanish tax specialisation, without indexing of Spanish law, without GDPR guarantees and without exact article citations. IgeraGestories starts at €99/month and includes pre-indexed Spanish legislation (LIRPF, LIS, LIVA, LGT), citations with article numbers, a signed DPA and updates within 24 hours of BOE publication.
Does IgeraGestories update automatically when the law changes?
Yes. IgeraGestories updates its regulatory database within 24 hours of publication in the BOE. ChatGPT has a fixed knowledge cutoff: it does not know about tax reforms approved after its training date and cannot access current legislation in real time.
Can I try IgeraGestories before committing?
Yes. IgeraGestories offers a 14-day free trial with no credit card required. During that period the base legislation (LIRPF, LIS, LIVA) is already pre-indexed and you can upload your own agreements and circulars to see how the assistant responds with your actual documentation.
14 days free. No credit card.
