Lethara gives immigration firms AI that strips PII before it reaches any model, so your team moves faster without exposing client data.
ChatGPT has no data processing agreement with your firm
Every prompt your staff sends may include client PII
ABA Rule 1.6 and AILA guidance apply to AI tools
Lethara sits between your team and any AI model. Before a prompt is sent, it detects and tokenizes names, A-numbers, passport data, case details, and any other PII. The AI sees anonymized input. Your client data never leaves your control.
Your team writes in plain language, same as they would in any chat tool.
Names, A-numbers, passport data, and case details are replaced with encrypted placeholders before the prompt leaves your environment.
The model sees no raw client data. The response comes back with original values restored, so your staff reads a natural answer.
Client data is tokenized and stored in an encrypted vault. The AI model only ever sees placeholders. Originals are restored after the response, staying entirely within your workspace.
Built around ABA Model Rule 1.6 and AILA AI guidance. Because PII never reaches your AI provider, no data processing agreement is required with them. Your compliance posture stays clean.
Works with the AI tools your team already wants to use. No new software to learn, no workflow overhaul. Staff get the same conversational experience, with a privacy layer they never have to think about.
