Recall vs Open Notebook: 2026 comparison

Recall and Open Notebook in brief

Recall and Open Notebook help you organize source material, summarize content and retrieve knowledge through conversation. Their emphasis differs in how you build and use that collection. Recall combines article and video saving with automatic organization, a knowledge graph and revision quizzes. Open Notebook structures documents into notebooks, provides cited answers and creates podcasts with multiple speakers. Your working environment also matters: Recall lists mobile apps and an extension, while Open Notebook specifies local hosting, open source code and a wider range of interface languages.

Recall : Recall lets users save articles and videos and summarize videos, podcasts and PDFs. It serves people who want to organize and connect knowledge, query their library through conversation and review content with quizzes.

Open Notebook : Open Notebook organizes documents into notebooks for people who want to query and search their sources. It provides cited answers, summarizes content and creates podcasts with multiple speakers.

They are often weighed against each other by people who hesitate. This page lines up their features point by point (10 criteria), with no partnership with either publisher.

Comparison table

Criterion by criterion

For each criterion: why it matters, each one's value and who has the edge. A criterion without data on both sides is not decided.

Free tier

A free tier lets you test the tool on your own examples before paying anything. Recall : yes. Open Notebook : yes. A tie on this point.

Entry price

The first paid plan, per month, gives the minimum cost of regular use; higher plans cost more. Recall : $10 per month. Open Notebook : not published. Cannot be decided: data missing on one side.

Public API

An API lets you connect the tool to your software, an automation tool or an AI agent. Recall : yes. Open Notebook : yes. A tie on this point.

Data export

Being able to get your content back avoids lock-in the day you want to switch tools. Recall : yes. Open Notebook : yes. A tie on this point.

Data hosting

Where data is stored matters for GDPR and client data: the EU or local processing make compliance simpler. Recall : several regions. Open Notebook : on device. Edge: Open Notebook.

Interface languages

More interface languages make the tool easier to roll out across an international team. Recall : 1. Open Notebook : 14. Edge: Open Notebook.

Platforms

The more platforms (web, desktop, mobile, extension), the better the tool fits your daily routine. Recall : web browser, iPhone and iPad, Android, browser extension, and API. Open Notebook : web browser, Windows, macOS, Linux, and API. A tie on this point.

Open source

Public code lets you audit the tool, self-host it and keep using it if the publisher changes course. Recall : no. Open Notebook : yes. Edge: Open Notebook.

Track record

A tool launched several years ago has a longer history: less risk of sudden shutdown, more user feedback. Recall : launched in 2022. Open Notebook : launched in 2024. Edge: Recall.

Recognition

The number of reference community lists citing the tool shows how well known it is among practitioners. Recall : cited in 1 list. Open Notebook : cited in 1 list. A tie on this point.

Our analysis

Recall, launched in 2022 by Recall Wiki, Inc., brings together several stages of building a personal knowledge library. You can save articles and videos, summarize material, organize it automatically and connect knowledge in a graph. Quizzes extend that workflow into reviewing what you have collected. Open Notebook, launched in 2024, centers its listed functions on document notebooks, searching documents and notes, and asking questions with cited answers. Podcasts with multiple speakers provide another way to present the material. These differences suggest distinct priorities: collecting and revisiting knowledge with Recall, or working through organized source documents and their cited content with Open Notebook.

Recall uses a freemium model and has a free offering. Its Plus plan is listed at USD 10 per month, billed annually. Open Notebook is described as open source and also has a free offering, but its entry price is not published. These records do not establish the full cost of equivalent usage. Recall scores 78 out of 100 for access and transparency, compared with 68 for Open Notebook; these are not quality ratings. Their category positions are first and fourth out of fourteen respectively. Each appears on one community list, which provides no further basis for estimating user numbers or judging satisfaction.

Recall specifies mixed hosting, whereas Open Notebook specifies local hosting. Recall's code is closed and Open Notebook's code is open. Those distinctions matter when considering control over your working environment, but they do not describe every data flow involved in individual features. The records do not detail retention policies or the processing associated with summaries and conversations. Recall exports Markdown files in a ZIP archive, giving a stated format for taking content out. Open Notebook lists MP3 exports and text transcriptions of podcasts. Its record does not document a complete notebook export, so you should distinguish the listed audio outputs from broader portability of your document collection.

Recall lists web, iOS and Android access, plus an extension and an API. That range can suit collecting material across mobile devices and the web. Its interface has one language, although the record identifies neither that language nor French support. Open Notebook lists web, Windows, macOS, Linux and API access, with fourteen interface languages including French and Spanish. Its listed coverage therefore fits desktop work in those languages. Both tools summarize and let you query content, but no volume limits or performance measurements are supplied. Recall explicitly lists quizzes and a graph, while Open Notebook explicitly lists cited answers; those differences can shape your daily routine.

Depending on your situation

The right choice depends on use. For a few common situations, here are the criteria that matter and who wins (Recall value / Open Notebook value).

Personal use on a tight budget

Here, Open Notebook has the edge: it wins 1 of the 3 criteria that matter in this situation, namely free tier (yes / yes), entry price ($10 per month / not published), and interface languages (1 / 14).

Business use with client data

Neither stands out on the criteria for this situation (data hosting (several regions / on device), data export (yes / yes), and track record (launched in 2022 / launched in 2024)): decide with a trial.

Integration with your software

Here, Open Notebook has the edge: it wins 1 of the 3 criteria that matter in this situation, namely public api (yes / yes), open source (no / yes), and platforms (web browser, iPhone and iPad, Android, browser extension, and API / web browser, Windows, macOS, Linux, and API).

Which one to choose?

Choose Recall if…

• you value track record (launched in 2022)

Recall fits a routine built around saving articles and videos, connecting ideas in a graph and reviewing material with quizzes. Its mobile apps and extension are relevant if collection happens across devices. You should be comfortable with mixed hosting and closed code, and check the interface language and free offering against your needs before assuming they cover your intended workflow.

Choose Open Notebook if…

• you value data hosting (on device)
• you value interface languages (14)
• you value open source (yes)

Open Notebook fits readers who prioritize document notebooks, cited answers, local hosting and open source code. Its fourteen interface languages include French and Spanish, and its podcast creation supports multiple speakers. Check its practical cost and portability requirements: the entry price is unpublished, and the listed exports cover audio and podcast transcripts rather than documenting a complete export of notebooks.

Strengths and limits of each

Recall

• + Free tier to try it
• + Public API
• + Established since 2022

Open Notebook

• + Free tier to try it
• + Public API
• + Public source code

The best test is still yours: take three real tasks from your day and give them to both for a week.

What about the others?

If neither suits you, look at Obsidian, Glasp, Mem, Reflect, Limitless, and Elephas.

Conclusion

Recall is the more direct match for collecting, connecting and reviewing content, especially when mobile access matters. Open Notebook aligns with local document notebooks, cited answers and podcast creation. Interface languages and export requirements may decide the choice as much as the shared summary features. Use the access and transparency scores as a specific reference point; they do not establish answer quality or determine which workflow will suit you.
