SumizAI and Khoj side by side: price, licence, platforms and what each one actually does. ## What Khoj is Khoj is an open-source, self-hostable AI assistant its creators describe as a "second brain" — combining chat with any language model, semantic search across your own documents, and automation of repetitive research tasks in one tool. Backed by Y Combinator (W24 batch), the project has gathered more than 34,000 stars on GitHub and is released under the AGPL-3.0 licence. Key features: Semantic search built on pgvector indexes PDFs, Markdown, Word documents, Notion exports, and other formats, letting you ask questions in natural language instead of searching for exact keywords. Khoj talks to whatever model you connect — local (Llama 3, Qwen, Gemma, Mistral) or cloud (GPT, Claude, Gemini, DeepSeek). The ability to build custom agents with a defined persona and toolset lets you assemble specialized assistants for specific tasks, and scheduled automations can run recurring research on their own without manual triggering each time. Access from multiple platforms: Khoj integrates with a browser, an Obsidian plugin, Emacs, a desktop app, a phone, and WhatsApp — you can use the same assistant from inside a tool you already work in rather than switching to a separate app. Who it's for: Khoj appeals to people who want full control over where their data physically lives and which AI model processes it — from a single user running Khoj locally on their own machine to teams deploying it on their own cloud infrastructure at enterprise scale. Use cases: In practice, Khoj works well for searching a large archive of your own documents semantically rather than by exact keyword match, building a specialized research agent with access to a specific file collection, and automating recurring information gathering, such as a weekly newsletter generated from new documents in a given folder. Pricing and business model: Khoj is free and open source for self-hosting — the only cost is the infrastructure you run it on, plus any API charges from cloud models if you choose not to rely solely on local ones. A hosted cloud version run by the creators is also available, with a separate pricing model. Limitations and what to watch for: Getting the full value out of Khoj — custom agents, automations, pgvector integration — takes some technical know-how when self-hosting. Docker installation is the simplest path, but configuring it around your specific documents and models takes time. AI notes from Khoj's research automations: Khoj can generate summaries and semantic search results, but it doesn't offer a dedicated file system for building a lasting archive — the output of an automation or conversation has to be moved by hand into a separate notes system as a ai notes entry if it's meant to outlive the current session or a newsletter email. Privacy when choosing a cloud model: Even when opting for a cloud model instead of a local one, Khoj stays flexible about the provider — you choose which API you trust with your documents, rather than being tied to one provider baked into the app. That sets Khoj apart from closed assistants where the model choice and privacy policy are fixed once and for all by the app's maker. AI notes as the missing link in Khoj's workflow: Despite its extensive search and automation features, Khoj doesn't offer one consistent place where ai notes generated during a work session automatically accumulate and link to each other — every result has to be deliberately moved into an external system if it's meant to durably enrich a ai notes archive rather than vanish along with the chat history once the window closes. Y Combinator backing as a signal of project maturity: Participation in Y Combinator and a scale of more than 34,000 GitHub stars set Khoj apart from many smaller, hobbyist open-source projects in this category — for a team weighing a long-term deployment, that is an argument that the project has backing and motivation to keep developing, rather than a one-off burst of a creator's enthusiasm. Documentation and community: An active community around Khoj on GitHub and in documentation discussions means configuration problems during self-hosted deployment usually already have a documented fix — it's worth checking existing issues before solving the same problem from scratch. Open source as a guarantee of independence: Because Khoj is fully open source, users aren't dependent on one company's business decisions about the product's future — even if official development stopped, the code remains available for the community to maintain or fork, unlike closed AI assistants that disappear the moment their maker decides to shut the service down. Scaling from one user to a team: The same Khoj installation, run locally by one person for private use, can be scaled up to a team deployment on your own cloud infrastructure without switching software vendors — the difference comes down to server scale and account count, not migrating to an entirely different tool. What's worth checking before choosing: Before deploying Khoj, check whether your documents — formats, library size — are well handled by pgvector indexing, and whether you have enough hardware if you plan to run local language models instead of cloud ones. Bottom line: Khoj is a full-featured, open-source AI assistant combining chat, semantic search, and automation, accessible from multiple platforms and fully self-hostable. Anyone who wants worthwhile answers from such sessions to land automatically as ai notes in a searchable archive without manual copying should consider a tool built around that workflow. Comparison with SumizAI: Khoj and SumizAI differ in scope. Khoj is a multi-function assistant — semantic search, automations, agents — with chat as just one of several pieces, requiring self-hosting for full data control. SumizAI focuses on a single flow: a conversation with an AI model, connected through your own API key to one of seven providers, most of which Khoj also supports, turns automatically into ai notes — Markdown files in a vault you own, with no need to run your own server infrastructure. Anyone who needs a broad AI toolkit with automations will pick Khoj; anyone who wants a simple tool where these notes from AI conversations build themselves, with no server to manage, will find SumizAI the better-fitting solution. **Key facts** - Price: Free - License: Open Source - Origin: India - Category: AI Chatbot, Large Language Model (LLM) ## What SumizAI is A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk. A vault is a directory holding `base.md`, a generated table of contents up to six levels deep, and a `notes/` folder with one `.md` file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist. The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used. ## Where they differ - Khoj is a place to have the conversation. SumizAI is not a chatbot — the conversation is the input, not the product. What comes out of it is a `.md` file with a title, a place in `base.md` and a duplicate check against the notes already in the vault. If you only want to talk to a model, you do not need SumizAI. - Khoj is open source (AGPL-3.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Khoj. The guarantee SumizAI offers instead is structural rather than legal: the notes are Markdown files in a folder you chose, so they open in any editor whether or not the application is running. - AlternativeTo's description of Khoj does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard `.md` files to a folder you picked, and an unpaid account can still export all of them. - Khoj can be self-hosted. SumizAI has nothing to host on the desktop — the vault is a folder on your machine — and if you want the model on your own hardware too, a local Ollama is one of the seven providers it speaks to. - Khoj's description mentions voice. SumizAI has no voice input and no transcription — the input is a typed conversation. - AlternativeTo lists no mobile version of Khoj. SumizAI runs on macOS, Windows, iOS and Android. - Both search. SumizAI's search reads the whole note — title, summary, body and the original question and answer — rather than titles alone.
