When your engagements involve
This isn't the kind of data you casually paste into ChatGPT.
Yet someone in your industry pasted exactly this into a chatbot this week.
Before you paste interview notes anywhere, mask the personal details first.
How Elephas works with your engagements
Your documents stay stored on your computer. Search is built on your computer. You choose where answers are generated: Elephas AI, your own API key, or a model on your computer.
Add your engagement files to a Brain
Create a Brain for each client or engagement. Add your PDFs, Excel models, Word documents, and slide decks, or add a whole folder. Elephas reads and indexes them on your computer.
Ask in plain language
"What did the interviews say about churn?" Elephas searches your documents, reads the relevant passages, and writes an answer. Every answer cites your files. Open a source to see the quoted passage and the page, slide, or sheet it came from.
Choose where the answer is generated
Use Elephas AI, your own API key, or a model on your computer. Before a question leaves your computer, Elephas hides personal details such as names, email addresses, and phone numbers, then puts them back in the answer.
Stays on your computer
Your engagement files, the search index, and your chats. The index and chats are kept in an encrypted database.
Sent when you ask with a cloud AI
Your question and the passages Elephas picked from your documents, with personal details hidden first.
Sent with the on-computer model
Nothing. Answers are generated on your computer.

The private ChatGPT alternative for consultants
A chatbot asks you to upload the file first. Elephas keeps your documents stored on your computer and sends only your question and the passages it picked, with personal details such as names, email addresses, and phone numbers hidden first. Answers come from your decks and models, not the internet.
Proposal research grounded in your past engagements
Add your past SOWs, case studies, and winning proposals to a Brain for the client. Ask what you scoped, how you framed it, and what won the work. Every answer cites your files, so the next proposal starts from what you actually wrote.
Due diligence review at data room scale
Add a folder with hundreds of data room PDFs. They stay stored on your computer. Ask for a risk summary, a timeline, or every mention of a clause. Elephas searches your documents and cites the page.
Elephas vs ChatGPT, Claude, and NotebookLM
A plain comparison of the tools consultants weigh against each other.
| Elephas | ChatGPT (consumer) | Claude (consumer) | NotebookLM | |
|---|---|---|---|---|
| Where your documents are stored | On your computer | Uploaded to the provider | Uploaded to the provider | Uploaded to the provider |
| Personal details hidden before the model sees them | Yes, and you can see what was hidden | No | No | No |
| Choose where answers are generated, including on your computer | Yes | No | No | No |
| Sources that show the quoted passage and its page | Yes | Varies by plan | Varies by plan | Yes |
| Share with a team, end-to-end encrypted | Yes | Varies by plan | Varies by plan | Varies by plan |
Comparison reflects published information as of 2026 and can change, so check each provider's current terms. NotebookLM is strong for research on sources you are free to upload. ChatGPT and Claude are general chatbots. Elephas is the option when your files are covered by an NDA and you want them to stay on your computer.
Client diligence, answered
When a client asks how you use AI, you have a real answer
More clients now ask their advisors how AI touches their data. These are the three questions they ask, and the answers you can give in writing.
Does a third-party model provider retain or train on my data?
When you ask with Elephas AI, your question and the passages Elephas picked from your documents are sent through the Elephas gateway to the AI model. They are not stored and are not used to train AI models.
With your own API key, your provider's terms decide what is kept. With the on-computer model, answers are generated on your computer. Nothing is sent anywhere.
Where are my engagement files and chats kept, and for how long?
Your documents stay stored on your computer. The search index and your chats are kept there too, for as long as you keep them.
When you ask with a cloud AI, only your question and the passages Elephas picked are sent, with personal details hidden first.
On sync: sync is off until you turn it on, and it is part of the Professional and Team plans. Sync is end-to-end encrypted. Our servers hold only encrypted data that we cannot read.
Can I delete engagement files and related data at any time?
Yes. Your engagement files, the search index, and your chats are stored on your computer, so you delete them there. To ask about account data, email support@elephas.app.
Filling out a client's vendor security questionnaire? Write to the same address. We will respond directly rather than hand you a generic policy link.
Three ways to get an answer. You pick the route for the engagement.
Your documents stay stored on your computer. When you ask a question, you choose which AI answers it.
Ready the moment you install
When you ask with Elephas AI, your question and the passages Elephas picked from your documents are sent through the Elephas gateway to the AI model. They are not stored and are not used to train AI models. Personal details are hidden first.
When to use it
Everyday questions, synthesis, and research across your engagement files.
Your own AI account
Use your own account with OpenAI, Claude, Gemini, and others. With your own API key, requests go straight to the provider you chose. Elephas cannot see them. Available on the Personal and Professional plans.
When to use it
Firms that already have terms with a provider. With your own API key, your provider's terms decide what is kept.
A model on your computer
Download a model once. With the on-computer model, answers are generated on your computer. Nothing is sent anywhere. Answers are simpler than on the cloud routes. Elephas needs an internet connection to sign in and to confirm your plan.
When to use it
Engagements under strict NDAs, unannounced deals, and anything your client would not want sent to a cloud AI.
Personal detail protection
Personal details are hidden first, for client work
Before a question leaves your computer, Elephas hides personal details such as names, email addresses, and phone numbers, then puts them back in the answer. You can see what was hidden under every answer.
This is detection, and it can miss things. Protection covers English, German, Spanish, French, Japanese, and Chinese. Check what was hidden when it matters, and add your own Protected Names for each Brain. For the engagements where nothing should be sent, use the on-computer model.
What this looks like for consulting work
- Client contact details such as names, email addresses, and phone numbers are replaced with placeholders on your computer
- The details are put back in the answer you read
- Under each answer, open the hidden details list to see what was replaced
- Add Protected Names per Brain for the clients and people you always want hidden
- On by default for Elephas AI and for your own API key
Honest note: detection will not catch every sensitive sentence in free-form narrative. It is not a guarantee, and your NDA obligations stay with you. For the most sensitive engagements, use the on-computer model.

Elephas Team
For your whole firm
Put your firm's proposals, frameworks, and client files in a shared Brain, invite colleagues by email, and everyone you invite can ask it and get answers with sources. Each person's chats stay private to them, and sync between teammates is end-to-end encrypted.
private AI for teamsWhat it looks like in practice
Four things consultants ask their own files.
Turn 30 client interviews into a findings outline
Add your interview notes to a Brain. Ask for the recurring themes, the outliers, and who said what. Each point cites the page it came from, and personal details are hidden before any cloud AI sees the passages.
Start the proposal from your past engagement documents
Ask what you scoped, promised, and delivered in your past SOWs, case studies, and deliverables. Every answer cites your files, so you reuse what already won.
Ask "what did we learn in discovery?" across hundreds of files
Ask in plain English and get an answer from your workshop notes, research PDFs, and interview notes, with the page cited. No re-reading the whole folder before the steering committee.
Check a figure before it goes in the deck
Ask where a number came from. Elephas answers with a source that shows the exact page, slide, or sheet in your client's files, so you see it before the client does.
Not another chatbot
Generic AI tools were built for open prompts on the open web. Your work is neither.
Generic AI chat
- × You upload the file to someone else's servers before you can ask about it.
- × No ground truth. The model confidently invents a market figure and you have to catch it before the client does.
- × Cannot see your actual engagement files. You paste in excerpts and hope for the best.
Elephas
- Your documents stay stored on your computer. With Elephas AI, your question and the passages sent with it are not stored and are not used to train AI models.
- Every answer cites your files. Open a source to see the quoted passage and the page or paragraph it came from.
- Answers come from your engagement files, not the internet.
