You add a page, a PDF, a YouTube video, an image or a sketch to a notebook, and the built-in assistant can summarise it, answer questions, translate dense passages or generate interactive graphs and small interactive applets. The design principles are privacy and openness. Your data is stored locally and can be imported, exported and managed as you like; the core source code is public on GitHub; and the intelligence layer is pluggable, so you can bring your own API key for a cloud model or run a local model instead of being locked into one provider. Surf has moved from a private alpha into an open beta, and the team describes ongoing work on speed and stability. It is free to use, aimed at students, researchers and curious readers who want an AI-assisted research environment rather than another chatbot in a sidebar. **Pricing & Plans:** Free and open source. Because the intelligence layer is bring-your-own-key, any model costs come from whichever provider or local model you choose to run. - **Unified research notebook:** Collect web pages, PDFs, images, notes and sketches into a single space instead of juggling separate apps. - **Local, open data:** Your content is stored on your device with import and export options, and the core source is public on GitHub. - **Bring your own model:** Connect cloud LLMs with your own API key or run local models, choosing the intelligence layer yourself. - **Citations in notes:** Generated notes link directly back to the source page, video or document they came from. - **Surflets and interactive output:** Turn dense material into interactive graphs and small apps without writing code. - **Media and PDF reading:** Summarise hours of YouTube video, long PDFs and foreign-language or scientific material in place. **Strengths:** Local data storage with open-source core gives real control; Bring-your-own-key avoids vendor lock-in on the AI layer; One workspace replaces tab clutter, note apps and PDF readers; Citations keep generated summaries verifiable against sources **Limitations:** Still in open beta, so rough edges and changes are expected; Requires you to supply a model key or local setup to get the most out of AI features; Fewer built-in integrations than mature note-taking suites [Profile (Markdown)](https://openaitools.app/tool/deta-surf.md) ## Elephas Elephas is built for the kind of work that should never be pasted into a general chatbot: contracts, client files, policies, research notes and reports. Instead of uploading documents to a cloud service, you point Elephas at files or entire folders on your machine. It reads and indexes them locally, then lets you ask questions in everyday language. Every answer comes with a source reference, so you can open the quoted passage and check it against the original page, slide or sheet. The privacy model is the core of the product. Documents, the search index and your chats stay on your computer in an encrypted database. When you ask a question, personal details such as names, emails and phone numbers are masked before the request leaves the device, and you can inspect exactly what was hidden under each answer. You also choose where answers are generated - the default Elephas gateway, your own API key for OpenAI, Claude or Gemini, or a local model that runs entirely on your machine with nothing sent anywhere. Elephas supports documents in English, German, Spanish, French, Japanese and Chinese, with cross-language search, and ships as a macOS and Windows desktop app. A team tier lets an organisation put shared contracts and policies into a common Brain with role-based access, private per-person chats and end-to-end encrypted sync. Pricing is a 7-day free trial with no card required, followed by individual plans and a Teams option at $29 per person per month with no minimum team size. **Pricing & Plans:** Free 7-day trial with no credit card required. After the trial, individual subscription plans apply, and Elephas Teams is priced at $29 per person per month with no minimum team size. - **Local document indexing:** Files, folders, PDFs, Word documents, spreadsheets, slides and scans are read and indexed on your own computer rather than uploaded to a third-party service. - **Answers with sources:** Every response cites the underlying file plus the page, slide or sheet it came from, so you can open and verify the passage yourself. - **Personal detail masking:** Names, email addresses and phone numbers are hidden before a question leaves your device, and you can view exactly what was masked under each answer. - **Choice of AI engine:** Use the default Elephas gateway, plug in your own OpenAI, Claude or Gemini API key, or download a local model so answers are generated on your computer with nothing sent. - **Shared team Brains:** Invite teammates to a common Brain with manager, contributor or reader roles, keep individual chats private, and sync through end-to-end encryption. **Strengths:** Documents, index and chats stay on your own machine in an encrypted local database; Every answer cites the exact file and page, making verification fast; You choose the AI backend, including fully local generation with nothing sent; Cross-language search across six languages without a language setting **Limitations:** Desktop-only: there is no browser version, so you need macOS or Windows; Answers still travel to a cloud model unless you pick local generation, and cloud requests are not end-to-end encrypted; Automatic masking of personal details can miss things, so answers should still be reviewed [Profile (Markdown)](https://openaitools.app/tool/elephas.md) ## Frequently Asked Questions ### How do Deta Surf and Elephas compare in monthly traffic?
