Spanlens is an open-source (MIT) LLM observability platform that lets developers monitor every call their application makes to OpenAI, Anthropic, Gemini, Mistral, OpenRouter, Azure OpenAI, or a local Ollama model. Integration takes one line: swap your client's baseURL to the Spanlens proxy, or run "npx @spanlens/cli init" and the wizard rewrites your code automatically. From that moment, every request is recorded with its model, token counts, latency, cost, and full prompt and response body, with streaming responses reconstructed automatically. The dashboard turns that raw log into operational insight. Cost tracking breaks spend down per request, per model, and per end user, and parses prompt-cache tokens separately so you see real cache savings rather than sticker price. Agent tracing visualizes multi-step workflows as Gantt waterfalls and node-and-edge graphs, highlighting the critical path so you can find the slowest dependency chain in a fan-out. Anomaly detection flags 3-sigma deviations in latency, cost, or error rate against a rolling 7-day baseline with root-cause hints. Alerts on budget, error rate, and p95 latency are delivered to Email, Slack, or Discord. Spanlens goes beyond passive logging. A regex-based PII and prompt-injection scanner inspects request and response bodies and can block injections at the proxy. The savings engine spots calls that match a cheaper model's profile (for example, a gpt-4o call that looks like a classification task) and estimates the monthly saving from switching. Prompt versioning with A/B experiments compares versions on latency, cost, and error rate using Welch's t-test for statistical significance, and an LLM-as-judge evaluation framework (judge with OpenAI, Anthropic, or Gemini) scores outputs against rubric anchors, with human agreement measured by Pearson r or Cohen's kappa. Reusable datasets power offline evals and regression checks.

RemoveSynthID is a browser-based utility for processing Gemini-generated images that may contain invisible SynthID watermark signals. Instead of relying on metadata removal, it works with pixel-level and frequency-pattern adjustments designed to reduce SynthID detectability while keeping the visible image unchanged. Files are processed locally in the browser, so images stay on the user’s device rather than being uploaded to a remote server. The tool supports common image formats including JPEG, PNG, and WebP, and is built for creators, designers, marketers, agencies, and everyday users who want a private workflow for handling AI-generated visuals. RemoveSynthID is best understood as a quality-preserving content processing tool rather than a guaranteed universal detector bypass. Effectiveness can vary depending on the image, compression, edits, and the detection system used. Users should keep original files and follow applicable platform rules, disclosure requirements, and local laws.

I'm Grishma, co-founder of Renée Space. I'm building this from Toronto, and I'm honestly a bit nervous but really excited to share what we've created. This is my first time 🤞(btw, we'd love to have you in our community as we grow: https://www.instagram.com/reneespace.ai/) Why did we build this? I'll be real with you, this started from a deeply personal place. 4 years ago, I moved to Toronto as an immigrant. New city, new country, no friends, no support system. Just me in a tiny apartment, trying to figure everything out alone. The loneliness was suffocating. I was drowning in my own head, and there was no one to reach out to. No one who knew my story. No one who'd notice if I disappeared. Therapy would have been a great help but was expensive. I had mental breakdowns that brought me to the edge. There were moments I didn't think I'd make it through. Therapy would have been a great help but was expensive and would take lot of time & energy to fin the right one. When I desperately tried mental health apps, they made it worse. Every time I opened them, I was a stranger again. Re-explaining my situation, my background, why I was struggling, over and over. It wasn't support. It was exhausting. And then I realized, I wasn't alone in feeling this way. I started hearing the same thing from friends, from Gen Z and Millennials around me. We're living through a loneliness epidemic. 1.9 billion people worldwide are struggling with it. 79% of Gen Z, 71% of Millennials. So with Praharsh, I built Renée. An AI Friend who actually remembers your story, like a real friend would. The companion I wish I had during my darkest nights. The therapist I wish I had through my breakdowns What makes Renée different? 🧠 Persistent Memory - The thing nobody else is doing. This is her superpower. 🌼 Holistic Approach - She suggests ways you can be more holistic in your mental health journey. 🤍 Notifications - She reaches out when she senses you could use some help 💸 Forver Free - we know what's it feels like, so we made chat forver free
