Ellie is a health companion app designed for people who are coming off GLP-1 medications such as Ozempic, Wegovy, Zepbound, or Mounjaro. It provides a week-by-week plan for tapering your dose, stretching doses with your prescriber, or maintaining your results after your last injection. The app is built around the idea that the hardest part is already done, and the real challenge is keeping the weight off when the medication stops suppressing appetite. Ellie turns published research and real-world clinic data into a practical structure. The app tracks your weight trends, gives you a personalized After Plan, and includes tools like Food Noise SOS for moments when cravings spike. It is an educational companion, not medical advice, and never recommends specific doses. Instead, it helps you hold the number you decided not to cross. Key Features The After Plan: A week-by-week timeline from your last dose or current taper, showing when water-weight jumps, when food noise peaks, and what to do in each phase so nothing surprises you. Food Noise SOS: A ten-minute protocol for moments when thoughts about food get loud, with a chart that shows the noise fading over weeks. The line you will not cross: Set your boundary once, and Ellie watches the 7-day trend, not a single weigh-in, to catch drift at 4 lbs instead of 20. Protein and strength floor: Simple daily protein targets and 20-minute home strength sessions that protect muscle while you hold your weight, without cardio guilt. Medication modeling: Ellie adapts to standard weekly doses, stretched intervals, stepped-down tapers, or life after your last dose, and never suggests a dose. Bring-to-your-prescriber export: A one-page summary of your real regimen, trend, and plan, so conversations with your doctor start from data. Who Should Use Ellie People who are currently on a GLP-1 medication and want to taper or stretch their dose while holding their weight. People who have stopped taking Ozempic, Wegovy, Zepbound, or Mounjaro and want a structured plan to avoid regain. People who have already maintained for months and want a tool that catches small drift before it becomes a larger problem. Healthcare-adjacent users who prefer evidence-based, cited educational tools to pair with their clinician's guidance. Frequently Asked Questions Do I have to be off my medication to use Ellie? No. Ellie is for holding your number on the medication, on less of it, or off it entirely. The plan adapts to whatever you and your clinician decided, including stretching doses, tapering, rationing a final box, or being fully done. Which medications does it cover? Ellie covers Zepbound, Mounjaro, Wegovy, Ozempic, the oral versions, and compounded semaglutide or tirzepatide. It models the level of whatever you actually take. Does Ellie tell me how to dose? Never. Ellie records the regimen you and your prescriber chose and never suggests a dose or interval. It also builds a one-page summary you can give your doctor, so medication decisions happen where they belong. Is this medical advice? No. Ellie is an educational companion built on published research with sources cited in the app. Every medication decision belongs with you and your prescriber. Is the app available now? Yes. Ellie is live on the App Store for iPhone, free to download, with a subscription unlocking the full plan. An Android version will follow.

Paste an email, a message, or a few sentences about your day to get a correction, the rule behind it, and practice built from the errors you repeat. Familiar rules, the same mistakes.

PrivateTechShares is an information and tools resource for people who hold equity in private companies. It helps founders, employees with ESOP options, ex-employees and early angels work out what their shares or options may be worth, what it costs to exercise them, how dilution changes their slice, and how a sale is taxed in their country. Free calculators and sourced guides sit alongside an optional paid toolkit for readers who want a structured, step-by-step assessment. Key Features A free estimator prices your stake off the company's last funding round, adjusting for common versus preferred shares and for liquidity, so you get a realistic range rather than a single number. Free calculators model exit waterfall payouts after investor preferences and the cost of exercising vested options, plus an AMT-aware version for US holders. Country guides cover Germany, the UK, France, Spain, Italy, the Netherlands and Poland, with sources shown and current 2026 figures. Company pages cover more than 250 US pre-IPO and EU unicorn names, from OpenAI and Stripe to Revolut and Mistral AI. The paid Equity Toolkit adds an 8-phase A to Z deal map with clear stop points, a live net proceeds calculator, a Deal Room control panel and 11 ready-to-send messages. An Equity Position Report runs your own grant through worth, exercise cost, dilution, exit waterfall and country tax scenarios in one sourced PDF. Who Should Use PrivateTechShares Founders and early shareholders who want a realistic value range and a clear view of transfer restrictions such as right of first refusal and board approval. Employees and leavers with vested options who need to understand exercise cost, the US AMT trap and the roughly 90-day window that often follows departure. Smaller private shareholders in the US and Europe looking at transactions of €10,000 to €750,000 that large secondary platforms often pass over. Frequently Asked Questions What is PrivateTechShares? An information and tools resource for people holding equity in private companies. It offers free calculators, plain-English guides and an optional paid toolkit, and it does not broker sales or hold shares. Is my equity worth anything before an exit? Often yes, though usually less than the last-round headline price. Most holders own common shares, which are worth less than the preferred shares investors bought, and the stake is illiquid, so the estimator returns a range. Do I need the company's permission to sell my shares? Usually there are transfer restrictions in your shareholder agreement, such as a right of first refusal or a requirement for board approval. That is not a dead end, but the transfer does need clearing with the company first. How is selling startup shares taxed? A gain is generally treated as a capital gain, though rates and rules vary by country. The site's country guides show cited figures for seven European markets, and it recommends confirming your position with a tax adviser. Does PrivateTechShares find buyers or sell shares on my behalf? No. It describes itself as an information and tools resource only, helping you understand your position and prepare while pointing to who typically buys private shares.

CiteTrue Citation Checker is a free, AI-powered tool that verifies every reference in a paper against authoritative academic databases. Paste a reference list in APA, MLA or another style and it reports which citations are genuine and which look fake or AI-generated. It is built for anyone who needs to confirm that a source exists and that its details are correct: students, PhD candidates, professors reviewing drafts, and journal editors screening submissions. Key Features Batch checking: paste a whole reference list and verify dozens or hundreds of entries in one run, not one at a time. Field-by-field verification: title, authors, year, DOI, venue, volume and pages are each compared with the matched record. Confidence scores: every citation gets a score showing how likely it is to be authentic, so weak entries stand out. Multi-database search: references are cross-referenced against sources such as Crossref, PubMed, arXiv, OpenAlex, IEEE, Springer and Wiley. Fabrication detection: invented DOIs, references to papers that were never published, and AI-hallucinated citations are flagged. Who Should Use CiteTrue Citation Checker Students and early-career researchers who want to avoid retraction risk before submitting a paper. Professors and advisors reviewing student drafts who need to spot fabricated references quickly. Journal editors and peer reviewers screening submissions, where bogus references are hardest to catch by hand. Frequently Asked Questions What is CiteTrue Citation Checker? A free citation verification tool that searches academic databases to confirm that each reference points to a real, correctly described publication, and flags citations that look fake or AI-generated. Which citation styles are supported? You can paste references in APA, MLA and other common formats. The checker standardizes the input before verification, so mixed or messy lists still work. How does the checker find errors? Each reference is split into fields and compared with indexed records, because a citation can point at a real paper and still have the wrong authors, year or DOI. Does it detect AI-generated references? Yes. A 2023 study found that 55% of GPT-3.5 citations and 18% of GPT-4 citations were fabricated outright, and ChatGPT-written medical papers averaged 4.3 incorrect components per reference.
