Heptabase vs Lattics

Heptabase is a visual knowledge base for students, researchers, and lifelong learners. Whiteboards and cards support visual thinking, while a block-based editor, bidirectional links, PDF annotation, daily journals, and a web clipper help organize material. Its AI can explain sources, take notes, and organize a knowledge base from PDFs, YouTube, notes, and journals. Heptabase supports web, Windows, macOS, Linux, iOS, Android, and a Chrome extension, and lists integrations with Readwise and Zotero. The free plan is available through collaboration, allowing edits to shared whiteboards and cards but excluding personal libraries, journals, tag databases, tasks, highlights, and AI features. The desktop app stores data locally, and notes and files are accessible offline. For AWS cloud storage, the company describes encryption in transit and at rest, but not end-to-end encryption. After a subscription or trial ends, users can access and export content indefinitely; creating or editing notes requires renewal. Paid plans start at $8.99/user/mo (annual), with a 7-day trial.

Lattics is a knowledge management and writing app for researchers, writers, and other knowledge workers. Its card library lets users organize, tag, and search small units of knowledge, then place them in project outlines. Articles and cards can be linked across projects with inline references and bidirectional links. For visual planning, the Graph offers Mind Map, Plot of Story, and Aerial views, alongside a timeline for story design, historical research, and project management.

Writing and research features include AI help with translation, proofreading, rewriting, creative writing, and consultation; bibliography generation; more than 8000 CSL citation styles; and journal layout templates. PDF tools support annotation and translation in 92 languages while preserving original formatting. Exports include PDF, Word, TXT, Markdown, PNG, and ePub. Lattics runs on web, Windows, macOS, and iOS, and works offline. Content is stored locally by default without registration or login; users may choose third-party cloud sync with end-to-end encryption. It offers a free plan, with Basic limits of 3 PDF translations and 3 OCR recognitions per 24 hours, plus 50 graph and timeline nodes per project.
