Hey everyone! 👋 I’m super excited to share Çetele with you today! The Problem: Traditional calculators force you to press `=` over and over, losing your history as soon as you clear the screen. On the flip side, opening Excel or Google Sheets for quick daily math, budget estimates, or currency conversions often feels like overkill. The Solution: Çetele is a fast, notepad-style calculator that evaluates expressions line-by-line as you type. Think of it as a smart scratchpad for your daily numbers. Key Highlights: - Line References & Running Totals: Refer back to previous lines using #1, L1, or prev, and calculate grand totals with total. - Live Multi-Currency, Gold & Crypto Math: Convert live rates on the fly ($100 to TRY, 1 gram gold to USD, 0.5 BTC to EUR). - Visual Sections & Subtotals: Group long documents into styled visual banners (=== Income ===) with sectional subtotal calculation. - Collapsible Section Blocks: Fold and unfold document sections in 1:1 synchronization between your editor and results. - Widescreen Focus Mode: Expand the calculation area (Ctrl + B) to hide the sidebar for a distraction-free workspace. - Local-First & Optional Cloud Sync: 100% offline usage out of the box (powered by IndexedDB) with optional Google Cloud Sync across your devices. - Instant URL Sharing: Share live calculations via shareable hash links. I built Çetele to make everyday financial planning, unit conversions, and quick math feel completely effortless. I’d love to hear your feedback, thoughts, or feature suggestions! What would make your calculation workflow even better? Thanks for checking it out! ❤️

the offline-first approach is honestly really thoughtful here, especially with the multi-currency and crypto conversions. typing "calc" naturally on a notepad instead of opening a separate app feels like exactly the kind of UX choice that just makes sense.
