SumizAI and Exa AI side by side: price, licence, platforms and what each one actually does. ## What Exa AI is Exa AI is the world's most powerful search. Business-grade search and crawling for any web data. Instead of relying on general-purpose search engines designed for the average individual user, Exa AI provides search and crawling infrastructure designed specifically for business applications and integration with other AI systems, requiring far greater scale and precision than typical consumer search. A paid-only model suggests Exa AI targets companies and developers building their own AI products that need access to high-quality, structured web data, willing to pay for business-grade infrastructure rather than relying on free but limited consumer search APIs. Being US-based and available both online and as SaaS positions Exa AI as infrastructure for product builders, rather than a tool for direct, everyday searching by ordinary users. Positioning as "business-grade" rather than consumer search addresses a real need among developers building AI agents and other systems requiring reliable, scalable access to up-to-date web data, where typical consumer search APIs prove insufficient in terms of limits, precision, or query flexibility. A development team building an AI agent that needs access to up-to-date web data, using Exa AI to feed that agent search results, gradually develops proven query-formulation patterns that produce the most accurate and useful results for a specific use case. Without systematically documenting those patterns, new team members have to discover them on their own through trial and error. SumizAI complements Exa AI exactly at that point: proven query-formulation patterns for Exa AI that produce the most accurate results for specific use cases can be saved as ai notes in a local Markdown file, building a company playbook for effectively using this search infrastructure. A team working on multiple projects that use Exa AI ends up with ai notes per use-case type, speeding up the rollout of every subsequent project. These tools complement each other: Exa AI provides powerful, business-grade search and crawling infrastructure for any web data, while SumizAI ensures proven usage patterns for that infrastructure survive as ai notes ready to use for every subsequent project requiring access to web data. For an engineering team building several independent products on top of Exa AI at once, such a collection of these notes effectively becomes informal but remarkably practical technical documentation, far more useful than generic API documentation because it emerges from the team's real, tested use cases. A startup building a research agent powered by Exa AI, processing thousands of queries daily in search of specific types of industry information, especially benefits from keeping a note documenting which query phrasings systematically return informational noise and which hit precisely the data needed. After a few months of such work, the team has a proven dictionary of effective query patterns, far more valuable than Exa AI's own generic technical documentation. A new engineer joining the startup, given access to such a note from day one, avoids the typical mistakes made by anyone formulating queries for a business-grade search engine for the first time without prior experience with this kind of specialized infrastructure. **Key facts** - Price: Paid - License: Proprietary - Origin: United States ## 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 - AlternativeTo's description of Exa AI does not mention an AI model. That is the whole starting point in SumizAI: you have a conversation with a model on your own API key, and the answers worth keeping become notes without you filing them. - Exa AI is paid software. Compare the two numbers directly: SumizAI is one dollar a month, one plan, and your AI provider bills you separately for the model you chose. - AlternativeTo's description of Exa AI 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. - Exa AI runs in the browser. SumizAI is a desktop and mobile application, and on the desktop the vault is a folder on your own disk rather than a document in someone's cloud. - Both search. SumizAI's search reads the whole note — title, summary, body and the original question and answer — rather than titles alone.
