Features and specs

What each product offers, as listed by its team.

Obsidian 6 features
Cipher by Sysapp.dev 10 features
  • Local-first
    Obsidian stores your notes locally on your device, giving you full control over your data and enhancing privacy.
  • Markdown Support
    Obsidian uses Markdown, making it easy to format text and compatible with many other text editors and tools.
  • Bidirectional Linking
    You can create bidirectional links between notes, which helps in building a knowledge graph and navigating related information more easily.
  • Customizability
    Obsidian is highly customizable with community plugins, themes, and various settings to fit different workflows.
  • Graph View
    Provides a visual graph view of your notes and their connections, aiding in understanding relationships and discovering insights.

Possible disadvantages

  • Learning Curve
    Obsidian can be complex and overwhelming for beginners due to its extensive features and customizable nature.
  • Sync Limitations
    While local-first is great for privacy, it requires additional steps or third-party solutions for syncing across devices.
  • No True Real-time Collaboration
    Obsidian lacks native real-time collaboration features, making it less suitable for collaborative work compared to cloud-based solutions.
  • Limited Mobile Features
    The mobile version of Obsidian, while functional, is not as robust as the desktop application, potentially hindering productivity on the go.
  • Dependence on Plugins
    Many advanced features require the use of third-party plugins, which could lead to compatibility issues and reliance on community support.
  • Performance on Large Vaults
    Performance might degrade with a very large number of notes or complex graphs, impacting usability.
  • Pattern insights
    The pattern you were too close to notice, what's likely driving it, and one thing to try
  • Source citations
    Ask any insight where it came from and it quotes the lines you wrote
  • No tagging or linking
    Write however you like. Related entries are grouped for you
  • Voice entries
    Dictate instead of typing. Long recordings are split as you talk
  • Guided start
    Four entry shapes to write against: a moment, a decision, a feeling, a pattern
  • Search by meaning
    Find an entry by what it was about, not the exact words you used
  • Goals
    Insights are weighed against what you're working toward
  • Pattern nudges
    A notification when a pattern surfaces, so you don't have to keep checking
  • Works everywhere
    Any browser, and installs to your phone's home screen
  • Memory
    Entries are kept permanently. Insights fade after 90 days, like working memory

Questions & Answers

As answered by people managing Obsidian and Cipher by Sysapp.dev.

Who are some of the biggest customers of your product?

Cipher by Sysapp.dev's answer:

Cipher is for individuals and it's in beta.

Which are the primary technologies used for building your product?

Cipher by Sysapp.dev's answer:

Go microservices, SvelteKit (the app, installable as a PWA), Next.js (the website), PostgreSQL, Qdrant for search by meaning, Redis, and AWS. Insights are generated through the OpenAI and Google Gemini APIs.

What makes your product unique?

Cipher by Sysapp.dev's answer:

You don't organise anything, and you don't have to ask it anything. You just write, and over time Cipher groups related entries and comes back with a pattern you were too close to notice, what's likely driving it, and one thing to try. Every insight can be traced: ask where it came from and it quotes the lines you wrote.

Why should a person choose your product over its competitors?

Cipher by Sysapp.dev's answer:

If you want a beautiful diary, there are good ones. If you want to chat with an AI about your day, there are good ones too. Cipher is for people who want their writing to add up to something, without tagging it, linking it, or asking the right question. And because every insight shows its sources, you can check it rather than take it on trust.

How would you describe the primary audience of your product?

Cipher by Sysapp.dev's answer:

People who already write things down, or want to: journallers, people who think in notes, people working through decisions, and people reflecting on how they feel. It suits anyone who wants to understand their own patterns. It's a reflection tool, not therapy, and it doesn't diagnose anything.

What's the story behind your product?

Cipher by Sysapp.dev's answer:

Regular journals felt like shouting into the void, and note apps were either too structured (Obsidian) or not structured enough (Apple Notes). I wanted something in between: write however I like, and have the patterns I couldn't see myself come back to me. You can't surprise yourself. Cipher is my attempt to work around that bug.
