Kensho Technologies

LightTag

Best overall

For everyday users, neither Kensho nor LightTag is a practical choice — Kensho is a high-end financial NLP tool for large enterprises, while LightTag is a specialized data-labeling platform for AI teams. The single biggest difference is that Kensho focuses on extracting structured data from financial documents and audio, whereas LightTag helps humans annotate text to train custom models. If you're a non-technical person looking for a ready-to-use AI tool, look elsewhere.

Common questions

Can I use Kensho or LightTag on my phone?

No. Neither tool offers a mobile app. Both require a desktop or laptop with a web browser or API access.

Is Kensho better than LightTag for transcribing meetings?

Kensho is better if your meetings are financial earnings calls and you need high-accuracy transcription with entity extraction. LightTag cannot transcribe audio at all.

Which tool is easier for a beginner to start with?

LightTag is slightly easier because it has a web interface for labeling, but both require technical knowledge. Kensho's 10-step API setup is far more complex.

Are these tools worth the price for a freelancer?

No. Both are priced for organizations. Kensho targets large financial firms; LightTag targets AI teams. Freelancers should look at simpler tools like Otter.ai or Label Studio.

Can I use these tools to analyze customer feedback from surveys?

LightTag could help you label survey text to train a model, but it won't analyze it out of the box. Kensho is not designed for general survey data.

Kensho and LightTag are powerful but niche tools for enterprises and AI teams — not for everyday users.

If you're a non-technical person, skip both of these. Kensho is for big finance teams, and LightTag is for AI developers. For everyday tasks like transcribing meetings or analyzing text, try simpler tools like Otter.ai, Notion AI, or ChatGPT instead.
