What are the 5 tools you simply couldn't do your work without?

This could be related to your industry, or even a side project you're working on.

Here are my 5 (I couldn't function without them):

  1. Grammarly – proofreading my texts, not just posts, but also client communication

  2. ChatGPT / Claude – mostly brainstorming, help with copy, and summarising

  3. Figma – I can put the basic graphics together quickly.

  4. Translator – sounds incredibly old-school, but English is not my mother tongue

  5. Gmail – and not only for communication, but also for storing ideas and sending myself email reminders for posts

[and soon one more that I am working on – – prevents me from being banned on LinkedIn, so I will not lose my account.]

What are your five?

Here's my five:

  • Research tool - Claude / chatgpt / Gemini/ Perplexity

  • Note tools - Notion is my top pick, Obsidian note is good too

  • Slack - the new Slackbot function, especially if connected with the internal knowledge base, is seriously underestimated. It's extremely useful to backtrace any past conversation, summarize updates, locate key documentations, etc. Sorry but other chat tools like Teams/Discord are just not compatible.

  • Design tools - Figma or Canva

  • Meeting tools - Zoom's AI note is pretty good, Google Meet is fine, never used Granola since it feels like an extra step.

My phone, A gmail account, ChatGPT, the internet, translator and canva

Mine are:

  1. Pocket - hardware for recording physical meetings and online, connected with Claude Code with their API

  2. Claude Code - Fable for orchestration, Opus for execution

  3. Paper MCP - replaces Figma and Canva through their amazing MCP, looks like magic everytime i 'summon' it

  4. PostHog - been using it for about a week but already crazy insightful

  5. Substack/Linkedin - Substack has been super interesting to see in terms of organic growth, Linkedin is my one excuse to actually be visible on social media

Mine are all research-heavy — I basically live in papers all day:

NotebookLM — I throw PDFs, transcripts and notes in and treat it as the thing I actually ask questions to. Closest thing I have to a second brain right now.

Claude — reasoning through messy problems and drafting.

Zotero — where every paper I've ever touched lives.

Obsidian — my permanent notes, the stuff I want to survive past a single project.

Readwise — catches highlights so they don't die inside a PDF I never reopen.

The gap I keep hitting is that NotebookLM is powerful but weirdly walled off from the rest of that flow, so I've been tinkering with a small workspace layer on top of it to make getting sources in and out less painful. Anyone else basically living in NotebookLM, or am I the odd one out?

Definitely ChatGPT / Claude. At this point, it’s not just a tool—it’s my unpaid co-founder doing 80% of the heavy lifting! 🤫😂

For me: a code editor, Git, a good terminal, ChatGPT, and a password manager. Those are the tools I use almost every day and would have a hard time working without.

Even in our office, we have an , and I can't imagine my working day without buying a snack.

My 5, as a solo founder running a bunch of small products:

Claude Code — most of my actual building lives here now

PostHog — every product's analytics in one project, so I see the whole funnel

Google Search Console — the only SEO signal I fully trust

Kamal — dead-simple deploys to my own servers, no PaaS bill

SEOBolt — full disclosure, I built this one: an SEO + LLM-search audit I dogfood on every site I own

Honestly the biggest unlock has been building the tool I personally needed and then living in it daily — the tightest product feedback loop I've found.

  1. Claude Code – My go-to for coding, debugging, and shipping product features faster.

  2. Kling – For generating AI videos and quickly testing creative ideas.

  3. CapCut – Makes editing product demos and social content incredibly fast.

  4. ChatGPT – I use it daily for marketing content, LinkedIn/X posts, and building my personal brand.

  5. ClickUp – Keeps our product roadmap, client work, and internal operations organized.

My five would probably be:

  1. ChatGPT for brainstorming, outlining, troubleshooting, and speeding up repetitive research tasks.

  2. Google Docs for drafting, editing, and keeping project notes organized.

  3. Canva for quickly creating graphics without needing a full design workflow.

  4. Gmail for communication, follow-ups, and keeping a searchable record of conversations.

  5. The Morse Lab for working with Morse code, decoding messages, and testing communication tools: ⁠

It is interesting how most of these tools are not just for one job anymore. They end up supporting writing, planning, learning, and side projects all at once.

i would say:

1. Supabase — my database and backend foundation for everything I build.

2. Vercel — deployment, routing, and stable hosting for all LogicBasis systems.

3. OpenAI — used mainly inside LogicBasis Room for writing, structuring, and accelerating cognitive work.

4. LogicBasis Room — my core workspace for clean thinking, system design, and operational clarity.

5. Technical AI support — for architecture, debugging, and deep technical knowledge.

I do more all in all cognitive use or for research and deep thinking
