[IDE/Editor] Show HN: AI Agent in Jupyter – Runcell I build runcell, an AI Agent in Jupyter Lab. It can understand context (data, charts, code, etc) in your jupyterlab and write code for you.<p>Runcell has built-in tools that can edit or execute cells, read&#x2F;write files, search web, etc.<p>Comparing with AI IDE like cursor, runcell focus on building context for code agent in jupyter environment, which means the agent can understand different types of information in jupyter notebook, access kernel state, edit&#x2F;execute specific cells instead of handling jupyter as static ipynb file.<p>Comparing with jupyter ai, runcell is more like an agent instead of a chatbot. It have access to lots of tools to work and take actions by its own.<p>You can use runcell with simple &quot;pip install runcell&quot; to start.<p>Any comments and suggestions are welcome.

[Other] Show HN: I built AI that turns 4 hours of financial analysis into 30 seconds I built Duebase AI to solve a problem I kept running into in fintech - analyzing UK company financial health takes forever. The process usually goes: download PDFs from Companies House → manually extract data to spreadsheets → calculate ratios → interpret trends. Takes 3-4 hours per company and requires serious financial expertise. The technical challenge: Companies House filings are messy. Inconsistent formats, complex accounting structures, missing data, and you need to understand UK accounting standards to make sense of it all. My approach:<p>Parse 15M+ UK company records from Companies House API Built ML models to extract and normalize financial data from varied filing formats Created scoring algorithms that weight liquidity, profitability, leverage, and growth trends Generate 1-5 health scores with explanations in plain English<p>What it does:<p>Instant financial analysis of any UK company (30 seconds vs 4 hours) Real-time monitoring with alerts for new filings&#x2F;director changes Risk detection that catches declining trends early No financial background needed to understand results<p>The hardest part was handling the data inconsistencies - UK companies file in different formats, use various accounting frameworks, and often have incomplete information. Had to build a lot of data cleaning and normalization logic. Currently focused on the UK market since I know the regulatory landscape well, but the approach could work for other countries with similar public filing systems.

[Other] Show HN: React Web Camera – Fix <input type=file> single-photo limit What we built<p>React Web Camera is a lightweight, reusable React component that allows users to capture multiple photos in one camera session, in-browser. It works across standard web apps, responsive UIs, and Progressive Web Apps (PWAs)—unlocking a smoother experience than the default &lt;input type=&quot;file&quot; capture&gt; element.<p>The problem<p>On mobile (and increasingly on desktops), using: &lt;input type=&quot;file&quot; accept=&quot;image&#x2F;*&quot; capture=&quot;environment&quot;&gt; only allows taking one picture before the camera closes. Want to add more? You have to reopen it each time.<p>How React Web Camera solves it<p>Opens the camera inline in-browser, Lets the user capture multiple photos in one go, Allows previewing captured photos, removing unwanted ones, and submitting everything in a batch, Fully client-side, respects user privacy, Supported across web, responsive UIs, and installable PWAs.

[Other] Show HN: Auto-Match – How We Built Receipt-to-Transaction Matching (Open Source) I’ve been working on automating bookkeeping tasks, and one big pain point was manually reconciling receipts with bank transactions.
