Day 2 of building chrome extension: highlight key points on any url. You can AI summarize the highlighted key points.
Today I implemented Oauth.
- use any auth lib on a project hosted on Vercel with JWT.
- Each time your chrome extension calls the API, the browser attaches http only cookie.

Super excited about the newly launched Vercel Workflows!
Inngest has `step .ai.infer()` to cut down serverless costs.
On Vercel Pro, you get very limited compute time - and slow AI calls especially to video models can drain that fast.
Now it looks like Vercel Workflows might finally fix this.

AGI is still very far away
Models like GPT-5-Pro, Claude Opus-4 and 4.1, and OpenAI o1 are too expensive for daily use.
On top of that, their performance doesn’t justify the steep increase in price.

structured outputs tips for aisdk:
prefer `nullable` over `optional` in your JSON schema.
Some providers (Azure/OpenAI via OpenRouter) require every property in required - optional props can trigger invalid_json_schema. Use null for missing, validate client-side.

My Vercel Pro usage is minimal. But the moment I switch to the free tier, I start getting usage warnings.
Still making $0, yet paying $20/month.
Entrepreneurship is hard.
Soon moving to Hetzner + Cloudflare CDN.
Same with the Neon Database
Only @Cloudflare R2 free tier - hasn't betrayed me yet.

V0 vs Lovable:
You don't need to learn how to code - worst advice ever.
Lovable: Looks like a spreadsheet but formulas doesn't work at all.
V0: couldn't even create a spreadsheet.
Ended up with @Syncfusion's Free Community Edition React SpreadSheet.

@obsdmd is better than Notion
It doesn’t even need AI to beat Notion.
Its advantage - notes are in Markdown. You can simply open the vault (which is just a folder) in Cursor.
You get autocompletion, Agents, ctrl+k quick edits.
Changes are instantly reflected in Obsidian

Day 6 of building Cursor for SpreadSheets: powered by aisdk and syncfusion SpreadSheet
Now Quick Edit can
- change formats (bold, underline, border color, thinkness, color, background color and everything else)
- merge and unmerge cells
- change values
- change formulas
You can also undo/redo.

Day 4 of building Cursor for Spreadsheets
AI Ctrl + K Quick Edit is Completed.
Claude, GPT-5, Gemini - all of them hallucinated Syncfusion's API. Even pasting the entire docs into the prompt didn't help.
So I went old-school: docs + console logs + endless tinkering. Finally, it works.

We are in Tech Bubble.
People still don't know how to use Cursor and Lovable.
They are paying $2500 just to build nextjs and supabase (image source: upwork)

But at the same time, I see that If we adapt a new tech, we will be able to find teh probelms and fix them quickly.

Transfer your domain to GoDaddy from Bluehost and save money.
On Bluehost, they charge you INR 2026. While Godaddy charges only Rs. 1199 (Tax included.) - it is the first year charge. 2nd year - 1700 (Tax included.).
Godaddy already includes Domain Privacy. But bluehost charges around INR 300.

How to store your react state into the url permanently:
- Instead of `useState`, use `useQueryState` + `NuqsAdapter`.
Now, to access searcparams in the server-side,
1. use `shallow: false`
2. `createSearchParamsCache` and its `parse`, and `get` methods

Right now there is a war going on between vercel and Cloudflare
Personally, I use both and like both - use Vercel for Nextjs App hosting and Cloudflare for Images and PDfs, and caching.
Slowly I will move my vercel and neon to Hetzner + Cloudflare.

I think it is possible.
1. First learn the app by using it extensively.
2. Describe the flow/features you use the most in the prompt. Don't clone other features. It simplifies things.
3. Ask AI to use your own frameworks you use the most to generate the code. Debugging will be easier.

Meanwhile, on repicate, i tried to buy $10 credit. All failed 4 years. On top of that, replicate says that unused credits expire after 1 year
