Idea type: Minimal Signal

There’s barely any market activity - either because the problem is very niche or not important enough. You’ll need to prove real demand exists before investing significant time.

Should You Build It?

Not yet, validate more.


Your are here

Your idea for a note-taking app with PDF, website, and picture integration, coupled with a Leitner system, falls into a category where there's minimal market validation. With only two similar products identified and low engagement (average of 1 comment), it suggests a niche problem or one that hasn't gained widespread traction yet. The absence of strong use or buy signals reinforces this idea. Before diving deep, it's crucial to validate whether a significant demand exists for this specific combination of features. Given the competition exists you must make sure that your app can compete with the top note taking apps, such as Notion, Evernote, OneNote, GoodNotes and Notability.

Recommendations

  1. Start by thoroughly researching existing note-taking apps and their features, especially those with some form of spaced repetition or PDF annotation capabilities. Understanding their strengths and weaknesses will highlight potential areas where your app can differentiate itself and offer unique value.
  2. Engage with potential users in online communities (Reddit, Discord, forums) related to note-taking, learning, or productivity. Describe your app's concept, emphasizing its unique integration of note-taking across various media with a Leitner system, and gauge their interest. Focus on the benefits your app offers that competitors do not.
  3. Offer to manually solve the note-taking and spaced repetition needs of 2-3 potential customers. This hands-on approach will provide invaluable insights into their workflow, pain points, and desired features. It will also show the value of your app and allow you to fine-tune your features.
  4. Create a concise explainer video showcasing how your app streamlines note-taking from different sources and integrates the Leitner system for efficient learning. Track the video's viewership and engagement to assess the level of interest in your app's core functionality. Focus on a specific use case such as how a user can use it to easily generate flashcards from PDFs.
  5. Implement a waiting list with a small deposit to gauge commitment. People are more likely to provide valuable feedback and become early adopters if they have a financial stake. If you're unable to secure 5 interested individuals within three weeks, it may be necessary to re-evaluate the market demand for your specific app concept.
  6. Based on the similar product's feedback, consider how your app might integrate with tools like Readwise, which is used for spaced repetition on read content. Integrating such tools would create a larger ecosystem for note taking.

Questions

  1. Given the crowded note-taking app market, what specific niche or user segment will your app target to gain initial traction, and how will the Leitner system integration be tailored to their needs?
  2. Considering the low engagement observed in similar products, what specific marketing and community-building strategies will you employ to generate buzz and foster a loyal user base for your app?
  3. How will you balance the app's feature set to provide a seamless user experience for both casual note-takers and dedicated Leitner system users, ensuring it remains accessible and valuable for all?

The maximum is +1, which means all comments (across all similar products) were positive, expressed a willingness to use & buy said product. The minimum is -1 and it means the exact opposite.

The y-axis captures the strength of the signal, i.e. how many people commented and how does this rank against other products in this category. The maximum is +1, which means these products were the most liked, upvoted and talked about launches recently. The minimum is 0, meaning zero engagement or feedback was received.

The sizes of the product dots are determined by the relevance to your idea, where 10 is the maximum.

Your idea is the big blueish dot, which should lie somewhere in the polygon defined by these products. It can be off-center because we use custom weighting to summarize these metrics.

Turn photos into text notes that sync to your Notion or Obsidian

Photes.io is a note-taking app that uses vision models to turn images into well-structured text notes. I built this tool because I often take photos of slides at meetups or conferences, but they just stay in my phone, unused for review or search.I started with a prototype using GPT-4 Vision to take notes in real-time and sync them to my Obsidian (story: https://x.com/ob12er/status/1797631061842944102).Now, I'm improving it to connect with more note tools like Notion and Google Docs.Looking for feedback and thoughts!obsidian plugin: https://photes.io/tools/obsidian

Solves input workflow problem, requests Readwise synchronization.
