Why people look for an alternative to NotebookLM

Sloppy citations

Gemini Notebook citations can be hard to follow because they link to a plain text version of your source document, stripped of styling and structure. Eno displays citations in your original document, scrolls to the passage, and highlights it.

Unwanted inputs

Answers informed by an unwanted web search is a liability. Eno only reads the files you give it. No settings to change, no constraints to add to the prompt.

Ignored instructions

"Keep it short." "Only use the contract." You shouldn't have to repeat these in every prompt or bury them in chat settings. Eno is built around one job, finding and showing the relevant text, so there's less for it to drift away from.

Wordy answers

Many Gemini Notebook users have noticed that simple questions now come back as multi-section write-ups. Eno answers in a sentence or two, then puts the passage in front of you so you can read the rest yourself.

“Ask eno a question and it shows you the answer. It does not tell you. It saves you the time of searching, but leaves you to review and analyze the data yourself.”

Litigator

“Owners are constantly asking questions about rules or regulations related to our condo. I can point Eno at our corporate documents and get a clear answer in seconds, rooted in the original source document.”

Who is Eno for?

Eno was built for people who work with large collections of complex documents and demand accuracy. Eno uses AI to find answers to difficult questions. It is able to reason over complex chains of interactions in documents such as contracts or statutes. Eno's evidence-based approach to AI places an emphasis on surfacing actual sections from your documents, rather than forcing you to rely on long-winded AI responses with vague citations. Typical customers are lawyers, engineers, academics, or other knowledge work professionals.

Does Eno use the web or other outside sources to answer questions?

No. Eno only reads from the files you provide it, never from external sources.

Do I need to upload documents to use Eno?

No, Eno runs locally on your computer, so you can use files already on your hard drive and it just works. Eno also integrates with Google Drive, Box, and Clio, so you can easily ask questions of files on those platforms too.

What file types does Eno support?

Eno supports PDFs (both scanned and text) and Word documents currently.

Is Eno free?

Yes, you get 1,000 free credits to start, then pay as you go.
