When your matters involve
This isn't the kind of data you casually paste into ChatGPT.
But without AI, you're stuck reading everything line by line.
How Elephas works with your matters
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 matter files to a Brain
Create a Brain for each matter or client. Add your PDFs, including scanned ones, Word documents, spreadsheets, and case notes, or add a whole folder. Elephas reads and indexes them on your computer.
Ask in plain language
"Which exhibit mentions the termination clause?" 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 or paragraph 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.

Your matter files, the search index, and your chats. The index and chats are kept in an encrypted database.

The private ChatGPT for lawyers
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 contracts and pleadings, not the internet.
AI contract review that keeps your contracts on your computer
Add executed agreements to a Brain for the matter. Ask for obligations, renewal dates, and termination triggers, and get answers with sources that show the exact page or paragraph in your own files.
AI legal document review and analysis
Add a 400-page deposition or a discovery production. Ask for a timeline of admissions, contradictions across witnesses, or every paragraph that mentions a term. Elephas can search your documents more than once, read the exact passages, and cite the page.
Elephas vs Harvey AI, Spellbook, and ChatGPT
A plain comparison of the tools solo and small-firm attorneys weigh against each other.
| Elephas | Harvey AI | Spellbook | ChatGPT (consumer) | |
|---|---|---|---|---|
| Where your documents are stored | On your computer | Uploaded to the provider | Varies by plan | Uploaded to the provider |
| Personal details hidden before the model sees them | Yes, and you can see what was hidden | Varies by plan | Varies by plan | No |
| Choose where answers are generated, including on your computer | Yes | No | No | No |
| Answers cite your own files | Yes, and sources show the exact page | Varies by plan | Varies by plan | Varies by plan |
| How you get it | Mac app you install yourself, Windows soon | Sold to firms | Word add-in | Web and desktop |
Comparison reflects published information as of 2026 and can change, so check each provider's current terms. Harvey is sold mainly to large firms. Spellbook focuses on contract drafting inside Word. Elephas is the option when you want your documents to stay on your computer, without a procurement cycle.
Diligence, answered
The three questions every attorney asks
Before your first client document touches an AI tool, these are the answers you want in writing. Here they are.
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 matter 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 matter files and related data at any time?
Yes. Your matter 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.

Three ways to get an answer. You pick the route for the matter.
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, summaries, and research across your matter files.
Your firm's 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
Matters where your policy requires that the question and the passages stay on your computer.
Personal detail protection
Personal details are hidden first, for legal 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. It works best in English. Check what was hidden when it matters, and add your own Protected Names for each Brain. For the matters where nothing should be sent, use the on-computer model.
What this looks like for legal work
- Client and 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 parties 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 it does not replace your own professional obligations. For the most sensitive matters, use the on-computer model.

Elephas Team
For your whole firm
Put your firm's precedents, policies, and matter 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 small-firm attorneys ask their own files.
Summarize a 60-page deposition
Add the transcript to a Brain. Ask for a timeline, a list of admissions, and key contradictions. Each point cites the page it came from, and personal details are hidden before any cloud AI sees the passages.
Pull the facts for a demand letter from the actual case file
Ask for the relevant paragraphs from your pleadings, exhibits, and correspondence. Elephas answers with sources that show the exact page, so every fact in your letter traces back to your own files.
Find the exhibit across 400 pages of discovery
Ask in plain English: "Which exhibit mentions the termination clause?" Elephas searches your documents and cites the page and paragraph.
Extract key dates, parties, and obligations from a contract stack
Add the executed agreements to a Brain. Ask for obligations, renewal dates, and termination triggers across all of them at once, each with its source.
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 citation and you have to catch it.
- × Cannot see your actual matter 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 matter files, not the internet.

That depends on the plan you use and on your own professional obligations, so read the provider's current terms before you paste anything in. Elephas works differently. Your documents stay stored on your computer. When you ask with Elephas AI, only your question and the passages Elephas picked are sent, and personal details such as names, email addresses, and phone numbers are hidden first. With the on-computer model, answers are generated on your computer and nothing is sent anywhere.

Your documents stay stored on your computer. The search index and your chats are kept there too. Elephas servers hold none of this unless you turn on sync.

Only if you turn it on. Sync is off by default and is part of the Professional and Team plans. Sync is end-to-end encrypted. Our servers hold only encrypted data that we cannot read. Your files and chats are encrypted on your computer before upload, and your other computers decrypt them and build their own search index. A new computer must be approved from one you already use. If you lose every synced device, nobody can recover the data, including Elephas.
