CoolDeep AI Digest

The author describes a systematic process of evaluating hundreds of AI tools and narrowing the list to seven that now power about 90% of their work, saving hundreds of hours previously lost to busywork. The core argument is that effectiveness with AI comes not from using many tools but from selecting the right few for specific jobs and mastering them. The seven tools are grouped by function: chatbots (ChatGPT, Gemini, Claude) are differentiated by strength—Claude for high‑quality writing that matches the user’s voice, Gemini for deep integration with Google Workspace and large context handling, and ChatGPT as a general‑purpose option. Perplexity serves as an accuracy layer, providing source‑based answers to reduce hallucinations. Whisperflow enables fast voice‑to‑text transcription, cleaning speech in real time and allowing users to produce text at speaking speed (~200 wpm) rather than typing speed. Gamma automates presentation design, turning raw content into polished decks without design expertise. NotebookLM creates a personal research repository that answers only from uploaded sources, cites them, and can generate summaries, quizzes, mind maps, or podcast‑style discussions. Granola captures meeting audio via system audio (no bot), merges user notes with transcripts, and can push action items to task managers. Nano Banana Pro (Google’s image‑generation model) lets users create and edit photorealistic images using plain English prompts, simplifying visual content creation. Practical takeaways include: match the chatbot to the task, use Perplexity for fact‑checking, adopt voice input for speed, leverage AI for design and research automation, improve meeting productivity without intrusive bots, and generate images via natural language. The author advises starting with one tool that solves an immediate problem, mastering it, then gradually adding others to build a personalized, time‑saving AI workflow.
