csvjson is a free, browser-based toolkit for converting data between the formats developers and analysts use daily: JSON, CSV, Excel, YAML, XML, SQL, and more. Every conversion runs entirely in your browser. Nothing is uploaded to a server. Nothing is logged. No account required, no file size limits. Converters include: JSON โ CSV, Excel, YAML, XML, SQL, TSV CSV โ JSON, Excel, SQL Excel โ JSON, CSV XML โ JSON, YAML โ JSON, NDJSON โ JSON Developer tools include: JSON Formatter, Validator, Schema Validator JSON Path Finder, Flatten JSON JWT Decoder, Regex Tester, Diff Checker SQL Formatter, Cron Builder Base64, URL Encode/Decode, Hash Generator (SHA-256/512) UUID Generator, Timestamp Converter CSV Viewer/Editor, CSV Cleaner QR Code Generator, Markdown Preview Developers use it to transform API responses, generate SQL seed data, decode JWTs, and validate schemas. Analysts use it to clean and reformat exports before loading into Excel or Sheets. Non-technical users use it to open a JSON file or convert a CSV without writing any code. Most online converters upload your data to their servers. csvjson processes everything locally using JavaScript โ your data never leaves your device. This matters for anyone handling production data, customer records, or anything governed by data privacy policies
Tempreon is a personal memory layer for your AI tools, connected over MCP. Your knowledge, preferences, and decisions travel across Claude, ChatGPT, Cursor, and any MCP-capable client โ captured once, available everywhere. It learns how you actually work instead of just storing what you said.

TempreonTempreon's answer:
Tempreon started with a simple observation: AI models keep changing, but the thing that makes them useful to you โ your context, your preferences, your judgment โ gets rebuilt from scratch inside every tool, and lost every time you move.
We built the layer that fixes that: person-owned memory served over the open Model Context Protocol, so it works across assistants instead of belonging to one. Along the way we open-sourced the pieces that are useful to everyone regardless of whether they use Tempreon โ like memhaul, our MIT-licensed CLI for turning ChatGPT and Claude data exports into files you own.
The through-line is custody: the model is temporary, your memory shouldn't be.
Tempreon's answer:
Most alternatives in this space are memory infrastructure for developers building their own AI apps. If you're the person using several AI tools every day, that's not your problem โ your problem is re-explaining yourself to each of them and losing everything when you switch.
The choice is really about who the memory is for. Ours is for you.
Tempreon's answer:
Tempreon is built for the person, not the app. Most memory products are developer APIs for adding memory to a single product; Tempreon is a memory layer you own that travels with you across every AI tool you use โ Claude, ChatGPT, Cursor, anything MCP-capable.
Tempreon's answer:
Individuals who live in AI tools all day: operators, consultants, founders, sales professionals, and knowledge workers who use more than one assistant and are tired of being a stranger to each of them.
If you've ever pasted the same context into Claude and ChatGPT in the same week โ you're the audience.
Tempreon's answer:
The protocol choice is the product decision: build on the open standard, and your memory works everywhere the standard does.
