App Ideas

Future apps to build for brandencollingsworth.com/apps

1. Token Budget Calculator ⬅️ IN PROGRESS

Paste text, see token counts across models (GPT-4, Claude, Llama). Visualize how much of a context window you’re using. Add “compaction simulator” that shows before/after when you summarize chunks. Ties directly to the memory compaction post.

3. Chunk Visualizer

Paste a document, adjust chunk size/overlap, see the boundaries highlighted. Calculate how many chunks, average tokens per chunk, estimate embedding costs. Great for RAG tuning. Connects to the eval bootstrapping post.

4. Model Cost Calculator

Input token counts or paste conversation, get cost estimates across providers (OpenAI, Anthropic, Google, local). Factor in context caching, batch discounts, thinking tokens. Shareable links for team estimates.

7. Keyboard Shortcuts Trainer

Pick an app (VS Code, Vim, browser), drill shortcuts with timed prompts. Track accuracy and speed over sessions. Gamified skill-building.
