Change tools
For everyday users who want a ready-to-use AI tool for search, summarization, or content generation, Cohere is the better pick — it works out of the box with a simple API and dashboard. Haystack is a powerful open-source framework for developers who want to build custom AI pipelines, but it's overkill and too technical for most regular people. The single biggest difference: Cohere is a finished product you can use today; Haystack is a toolkit you have to assemble yourself.

Common questions
No. Neither tool has a mobile app. You can access Cohere's dashboard from a phone browser, but it's not designed for mobile use. Haystack is purely a coding framework — no mobile access at all.
Cohere is much easier. You sign up, get an API key, and can start using it via the dashboard or a simple script. Haystack requires you to install Python, learn pipelines, and write code — it's not for beginners.
For a simple search engine, Cohere is better because its Rerank and Embed models are best-in-class and work immediately. Haystack gives you more control but requires significant setup to match Cohere's search quality.
Yes, Haystack is completely free and open-source. You pay nothing to use it. However, you may need to pay for third-party services like vector databases or LLM APIs if you use them with Haystack.
Cohere is better for summarizing documents because it has built-in summarization endpoints and supports PDFs and CSVs directly. Haystack can do it too, but you have to build the pipeline yourself.
Partially. Cohere's dashboard lets you test models and see results, but to integrate it into your workflow (e.g., automate summaries), you'll need to use the API with some basic scripting. It's not a no-code app.
Cohere wins for everyday users who want a working AI tool; Haystack is for developers who want to build their own.
If you're not a developer, go with Cohere — it's the closest thing to a finished product that actually works for search and summarization. Haystack is powerful but only if you're comfortable writing Python code and building pipelines from scratch. For most everyday users, Cohere is the practical choice.
