App Development and Growth

App Development and Growth

The speaker is relocating to Seoul for a few months to continue building and growing their apps. They’ve been trying to speedrun their startup and will show the changes made to their app since the last video, including a unique feature they built that doesn’t exist elsewhere.

New Domain and Landing Page

The writer started a new domain for their app, which is short, simple, and memorable, and doesn’t tie the app to a specific platform. They also improved their landing page by shifting from describing features to explaining the benefits and value of the app, aiming to give customers an immediate reason to try or buy.

Headlines and Interactive Demos

The author compares two headlines, one that simply states what the app does and another that explains why users need it. The author also discusses the importance of interactive demos and landing pages in converting users.

Startup Club and Community

The speaker created Startup Club to provide a community and resources they wish they had when starting their solo journey. They share that the most useful feature of their app is an AI chat feature for YouTube transcripts, allowing users to chat with videos and get quick summaries or insights.

AI Chat Feature and LLM

The speaker is aware of existing apps and browser extensions that allow rewatching videos, but they added a unique feature to their chatbot, LLM, which references specific timestamps in videos, enabling users to jump to specific moments. They also mention a humorous anecdote about being in a bad mood and the importance of being in a good mood.

Custom AI Pipeline and YouTube Channel Chat

The speaker has built a custom AI pipeline that allows users to chat with any YouTube channel and receive relevant video references in response. They’ve been using this tool to extract information from channels they regularly watch, such as Y Combinator, and find accurate answers to their questions about startups.

Pricing Model and Marketing Strategies

The author switched their app’s pricing model from credit-based to subscription-based due to increased costs from LLM providers. They wanted to keep pricing simple, so they introduced a single paid tier with unlimited AI chat and bulk transcript extractions, and users can choose between weekly or monthly plans.

Marketing Strategies

  • Boost the website’s SEO performance by optimizing it for search engine results.
  • Create useful content based on target keywords used by potential customers when searching for the app.
  • Ensure the site loads quickly and is mobile-friendly to optimize for search engines.
  • Create content on social media, leveraging existing experience and potential for viral growth.

Grammar Focus

Grammar Focus: Subordinate Clauses

Subordinate clauses are clauses that cannot stand alone as a complete sentence. They are introduced by subordinating conjunctions such as “because,” “although,” “if,” and “since.” In the provided text, subordinate clauses are used to provide additional information and to show cause-and-effect relationships. For example, “They’ve been trying to speedrun their startup and will show the changes made to their app since the last video” contains a subordinate clause “since the last video” that provides additional information about when the changes were made. Similarly, “They also improved their landing page because they aimed to give customers an immediate reason to try or buy” contains a subordinate clause “because they aimed to give customers an immediate reason to try or buy” that shows the cause of the improvement.
