Saiela

Swaps personal data for placeholders before it reaches an AI tool, and puts the real details back in the answer.

Saiela helps UK firms use AI tools such as ChatGPT, Claude and Copilot without handing them personal data. Before a prompt or a file leaves your browser, Saiela checks it on your computer and swaps names, email addresses, National Insurance numbers and other personal details for placeholders such as [PERSON_1]. The AI tool sees only the placeholders. When the answer comes back, Saiela puts the real details back on your screen. You need your organisation’s Saiela account Saiela is for staff at firms that use it. Your admin signs up at app.saiela.co.uk, sets the firm’s rules and connects each browser. Until your browser is connected and you’ve read your firm’s staff notice, the extension checks nothing, records nothing and sends nothing. What it does • Checks what you’re about to send to an AI tool, when you press Enter or the send button • Swaps personal details for placeholders, or warns you, or stops the send, following your firm’s rules • Checks files you add to an AI tool, whether picked, dropped or pasted (text, CSV, Excel, Word and PDF), and sends a cleaned copy instead (cleaning files needs the Team plan) • Looks for UK details: National Insurance, NHS and UTR numbers, sort codes and account numbers, postcodes, addresses and phone numbers, dates of birth, passport and driving licence numbers, card numbers, IBANs and email addresses, as well as names, your firm’s client names and sensitive wording such as health details • Shows staff your firm’s AI policy to accept, and short lessons on using AI safely at work • If it can’t check a page, it pauses the send or asks first, as your firm chooses Where it works Saiela runs only on the websites of the ten AI chat tools your firm can choose from in its admin console, including the ones from OpenAI, Anthropic, Microsoft and Google. It doesn’t run on any other website, and it can reach only those AI tools and Saiela’s app. What Saiela’s app receives The checking happens in your browser. To connect your browser, the extension sends Saiela your work email address. After that, Saiela’s app receives a record of what happened, such as the AI site, what was done, and how many of each type of detail were found, so your firm can see its rules working. If Saiela warns you and asks why you want to go ahead, the reason you type is sent too, and your firm can see it. Saiela never receives your prompts, your files or their names, the AI’s answers or the details it found. Records are stored in the UK.
