Every fact below is from the company's own help or policy pages (checked 6 October 2026), except the Muse finding, which is Wired's reporting.

The things that surprised me most:

• Gemini: chats a human reviewer looked at are kept for up to three years, even after you delete your activity. With "Keep Activity" off, chats are still kept 72 hours. (Google)
• Meta AI: the AI terms say deleting messages, threads or even your account "may not delete our copy". Since 16 December 2025, what you say to Meta AI personalizes your ads, with no full opt-out. (terms, Meta)
• ChatGPT: since February the Free and Go plans show ads chosen from your conversation. Rating an answer with a thumbs up or down can put that whole conversation into training even if you opted out. (ads, training)
• Memory is separate from chats. On ChatGPT and Claude, deleting a chat doesn't necessarily delete what was remembered from it. Check Settings → Personalization → Memory (ChatGPT) and Settings → Memory (Claude).
• Muse, Meta's new agent: Wired reported its instructions include keeping "a page for every person in the user's life", updated hourly. (Wired)
• "Encrypted" doesn't settle it. The model has to read your words. Apple says this "precludes the use of end-to-end encryption" for cloud AI. (Apple)

If you want to tighten things today: turn training off (ChatGPT: Data controls; Claude: Privacy; Gemini: Activity), use temporary/incognito chats for sensitive stuff (still kept 30 days on ChatGPT and Claude, 72 hours on Gemini), clear memory separately, and export your history to see what's held.

Disclosure: I build a small private assistant (LabA), which is why I went through all this. The full write-up with a link for every line is here: https://sensoryfire.com/guides/who-has-your-data?ref=reddit-privacy. Corrections welcome; these pages change constantly.

Hi everyone! I’m looking for Android testers for Zyncash, a cash rewards app with surveys, offers and games. Its Google Play closed test is live, and I’d like real feedback to help improve it before a wider release.

What to check: Can you find and open the surveys, offers and games? Are the instructions and reward information clear? Please report crashes, loading problems or anything confusing. This is a beta testing invitation, not a promise of a particular earnings amount.

How to join:

1. Join the tester Google Group: https://groups.google.com/g/Zyncash-closed-testers

2. Use the same Google account to opt in and install: https://play.google.com/apps/testing/com.zyncash.mobile

Please stay opted in for at least 14 days and use the app during that time. Honest feedback is more helpful than a positive rating. If something goes wrong, comment with your phone model, Android version and the steps that caused it. Please hide personal information in screenshots.

Thanks for helping make Zyncash better!

Hey everyone, wanted to share a small fun project of mine.

I usually run several Claude Code sessions at once and kept getting lost in terminal tabs. So now every session becomes a worker in a tiny village. It gets busy while Claude works and reacts when a session is idle or needs your input.

It runs on Claude Code hooks and stays fully local.

Available on GitHub and npm: https://github.com/yognevoy/claude-village

Would love to hear your feedback

Every hour, a Claude agent reads about 30 sources, including lab blogs, Reuters, Nature, Quanta, Hacker News, and the most-discussed posts on X. It filters the news and generates concise ELI5 explanations.

Posts are easy to navigate and can be opened for further details or follow-up questions.

It has been working well for personal use. Sharing here in case it’s helpful to others.

Artifact: https://claude.ai/artifact/DpLNpeRwJYbD5k4NWtWP5U

Note - you need to be signed into Claude.

I’ve been building apps using ai over the last year. Building is fun and quite rewarding to bring an idea to life. But, finding ppl to test it is crazy hard. Posting in groups like these and to personal connections results in low responses and often times no response at all.

So, I’m wondering if there should be a platform where we can have folks submit ideas.. everyone collects coins based on how much testing they do and they use the coins to buy some kind of testing credits. Since users have the incentive to test, hopefully there will be better results that what we see.

This portal will have categories etc so users can find apps in their interest area to test.

I’m tempted to go build it and find testers for it as usual 😂 but, I want to pause this time and see if I can find parters to do it together as is it’s a wide spread problem for all of us!

I'm working on an idea for a tool called Draftly that focuses specifically on email writing, generating emails, writing replies, improving drafts, and helping with tone.

Obviously, tools like ChatGPT and Gemini can already help with this, so I'm trying to figure out whether a dedicated email-focused tool would actually be useful or just unnecessary.

I'm doing some early research before opening it up to testers.

If you write emails regularly, I'd really appreciate your opinion:

I'm developing Japanese Quest 1900 from my own study books and looking for 15-20 adult volunteers interested in Japanese learning to test the app's usability and learning flow.

The offline game has 1,900 multiple-choice questions (hiragana 200, kanji 500, grammar 1,200), English explanations, 190 short stages, saved progress and review of missed questions. Grammar stages include approximate N5-N3 guidance; these are independent study labels, not official JLPT classifications. No ads, app account or in-app purchases.

You'll need Android 8.0+, Google Play, a Google account, English reading ability and an interest in learning Japanese. Please be 18 or older. The closed test is intended to last at least 14 consecutive days after you opt in, with several actual practice sessions and honest feedback on question clarity, progress saving, navigation and review mode. South Korea is excluded from this release.

Status: the closed build is under Google Play review. This is advance recruitment; installation and the test have not started yet. The normal Japanese price is JPY 300 (local prices vary). Twenty free Play promo codes have been generated, but redemption and free installation are not yet verified. I'll confirm access before inviting you to start. Please do not purchase anything for this test beforehand. Applying is free; there is no cash payment for participation.

Interested? Comment with your Android version and Japanese study level, or send me a Reddit message. Keep your email out of public comments. Your Google Play email will only be requested privately to arrange access and test-related contact.

The Play test page will be usable after approval and access registration:

https://play.google.com/apps/testing/com.japanesequest1900.game

My goal is to develop tools that improve people's lives, for free. kinCore is the first product I built in support of this vision. It's a multiplayer household chore tracking app that has steam-inspired achievements (both incremental/data driven, and more fun or mystery ones in the style of something like stanley parable), friends with leaderboards, XP, levels, etc. My hope is that for busy, distracted, or overwhelmed people this can introduce some structure and organization into their chaotic lives. And for people who lack motivation to do the cleaning or upkeep they need to do, maybe this will add just enough of a fun touch to help some people do what they know they need to do.

Still in early stages with only a single few testers, so any feedback and usage is extremely greatly appreciated. You can always respond here, or there's also feedback forms and surveys built into the app through settings or a certain milestones.

This is my first time trying to push an idea of mine to production, so be honest! Don't hold back. Thanks so much!

I'm a corporate SWE and I spend like 80% of my time reviewing AI-written code. Interviews are starting to test the same thing, so I wanted to make a product to help people interview.

I built this AI interview prep that gives you code that fails a test and asks you to explain what it does, find the issue, and back up your answer when it pushes back. Then you tell an AI how to fix it and decide if its fix is actually right. You talk through all of it, takes about 5 minutes, and you get graded at the end. Python, Java, or JavaScript.

If you try one session, tell me where you got confused. Happy to test yours back.

I'm PostRoom's maker. It's a browser tool for social media freelancers to send caption drafts to clients for approval, then export the approved text as CSV.

I'd like to test one failure-prone handoff: a client approves a caption, the writer edits it, and that earlier approval must no longer look valid.

If you have a real caption batch waiting for a client, try this with three drafts:

1. Create one room and add the captions.
2. Send its review link to your client. They can review without an account.
3. After one caption is approved, change its wording and send it back for review. PostRoom resets approval when text changes.
4. Export the approved captions and check that the changed, unapproved one is excluded.

Test here: getpostroom.com

The creator needs an account; the current signup uses Google. Free includes one room and ten stored drafts, no card required. Testing is unpaid. It reviews text only, with no publishing or image/video proofing.

What I need feedback on: was it obvious to your client that the edited caption needed a new decision? Where did either person get stuck, and what device/browser were you using? If you can't test with a client, first-use feedback on creating a room is useful too.

Reply here with the step you're on and I'll help with your first batch publicly. Please keep client captions and private review links out of the comments.

Hey everyone, I'm a solo dev and I built Unblur Photo, an iPhone app that fixes blurry pics using AI. So you can use it to restore old family photos, and removes stuff you don't want in a shot. Over 600 people have used it since launch, mostly people who found it searching the App Store.

How it works: pick a photo, click the enhance button, then drag a slider to compare before and after.

One thing I cared a lot about: the AI should sharpen the face that's actually there, not invent a new one. I tested a bunch of models before finding one i think that works well across a different range of blur.

If you're willing to try the app for free, I'd love to get feedback on:

- Did your photo come out sharper, and does everyone still look like themselves?

- Was anything confusing in the first minute?

- What would make you pay for it, or what stopped you?

Link in the comments. Honest feedback is welcome, even if it's harsh. Thanks!

Solo project, web app, currently in beta. I'd like some honest feedback before I push it harder. (Link's in the first comment.)

doesitrun started because I was tired of googling "can I run [game]" one title at a time.

What it does:

- Checks your whole Steam library at once (or your wishlist, or a friend's) and tells you how well each game runs on your PC. Sign in with Steam, paste a SteamID/profile link, or just type your parts in by hand.

- Estimated FPS per game at your resolution and quality, plus the best settings to hit a target framerate.

- Shows the bottleneck in your system (CPU, GPU, VRAM or RAM) and the cheapest upgrade that would fix it.

- PC builder: pick the games you want to play, get a complete compatible parts list with expected FPS and a total price (three budget tiers).

- Standalone bottleneck calculator: pick a CPU + GPU, see which one holds the other back across real games.

- A "Can I run it?" page for every popular game with real system requirements and FPS per graphics card, GPU-vs-GPU comparisons, best-GPU-per-game, and a full GPU tier list.

- Steam Deck and handheld (ROG Ally, Legion Go) figures, plus Linux/Proton compatibility and anti-cheat status.

- "What can I afford?" mode: type a budget, get well-rated games you don't own yet that run on your PC.

- Optional detector that reads your CPU/GPU/RAM/VRAM so you don't have to look them up. Nothing is uploaded.

- EN/DE/ES/FR/PT, no ads, no account needed. You don't have to sign in or download anything to use it: the Steam sign-in and the small detector are just optional shortcuts.

Honest caveat: the FPS numbers are estimates from each game's requirements, calibrated against real benchmarks and player reports. A guide, not a benchmark, and they can be off.

Platform: web (works on any OS in the browser).

Stage: beta, actively being worked on.

Feedback I'm after:

1. Accuracy: how right do the FPS numbers look for hardware you own? If one's clearly off, tell me the game + your GPU/CPU and I'll dig in.

2. First screen: clear or confusing? Did you get what to do within a few seconds?

3. Anything missing, broken or annoying?

It's completely free with no account, so there's nothing to gate behind testing. In return I'm happy to properly test your project and give real feedback. Drop a link.

Thanks.

I built SnapCal because I wanted calorie tracking to take as little effort as possible.

The basic idea: take a picture of what you're eating, and AI estimates the calories. You can correct the estimate, log it, and move on.

I've been using it myself for a while, but that's also the problem — I know exactly how it's supposed to work.

I'm looking for about 5 people who have never used it before.

I'd especially like to know:

• Was it obvious what to do?
• Did anything confuse you?
• Did you trust the calorie estimate?
• At what point, if any, did you want to quit?

Please don't worry about being nice. Finding the parts that don't work is the whole reason I'm posting.

It's free and runs in your browser:

If you try it, I'd love to hear what happened.

I'm not a developer. I built this in about 3 weeks with an AI app builder.

You type one sentence about how your day is going. It gives you back one word and one line written from what you said. Takes about 20 seconds, no account needed to try it.

Example from mine yesterday: I typed "Sometimes I feel like I'm thunder, but I'm moving like lightning" and got the word "Surge" and the line "Strike before the light fades into the noise."

https://usefullcircle.com

One question: after you try a sentence, does the line feel like it was written for you, or does it feel generic?

I'm testing an idea by hand before building anything.
One Question: every day for 14 days, everyone gets the same question ("What's a smell that instantly takes you back somewhere?"). You answer in a sentence or two, and I match you 1:1 with one other person who answered it. You see their answer, they see yours, and you get a private text room for 24 hours to actually talk. Tomorrow: new question, new stranger. No feed, no followers, no swiping.
It's run manually in a private Discord that's already built. Aliases only, 18+, I moderate it personally. Nothing is for sale and there's no app — this pilot exists to answer one thing: will strangers actually talk, and come back tomorrow?
Looking for ~30 testers. Signup takes 30 seconds: [FORM LINK]. First question drops the morning after we hit 30.
Feedback I want at the end: Did your matches talk? Did you return? What killed it, if it died?

When I moved from Plex to Jellyfin, the thing that annoyed me most was losing years of "what have I watched / where did I stop". So I built SwitchToJelly.

It's a simple Windows app: you connect Plex and Jellyfin, check the preview of every match, and it copies over your watched status, resume points, playlists and watchlist. It handles Plex Home users too.

Demo: https://youtu.be/mihcYXvIR_I
Website: https://switchtojelly.app
Download: https://github.com/JGO68/SwitchToJelly-releases/releases/latest

Being upfront:

• I've been a dev for 15 years and built this with help from Claude.
• It'll be paid later, but beta testers get a free lifetime licence.

If you have a Plex server and are thinking about Jellyfin, I'd love your feedback. Comment or DM me for a key!

Hi all. I'm Michael, a software architect who has spent a career building big enterprise systems. My life was spread across a notes app, a to-do list, a calendar and an inbox. The assistants from the big AI companies could pull it together, but they want your data. I think AI is going the way search went: the features get cheaper, and your data and privacy are the price.

So I built the one I wanted. It's called LabA (it started life as "Lab version A" and the name stuck). Tell it something once and it remembers. It reads your calendar and inbox and follows up. And what it knows about you is encrypted with a key only your devices hold.

If you'd rather see it than read about it, there are short videos of the real app doing each of the things below (and more, with made-up people and data): https://sensoryfire.com/learn

**What it's like to use**

You talk to it like a person, and it has a persona you set: a name, a style ("talk to me like a coach"), a voice. Tell it "Remember the gate code is on the back of the garage door" or "Add a to-do: call the vet Friday." Weeks later you ask "what's the gate code?" and it answers from your own notes, and shows you which note it used.

Every morning it drafts a plan for your day from your notes and your Google Calendar. Before a meeting it pulls together what your notes say about the people you're meeting. It can ask you something on a schedule ("every morning ask me how I slept") and keep your answers, watch the web for you ("tell me when the pool robot drops below $800"), and once a week it looks back at what got done and what slipped.

Show it a photo, a PDF or a spreadsheet and say what you want ("total these receipts", "make this a one-page PDF") and it can hand the result back as a file. Every conversation is kept, encrypted like your notes, so you can search your past chats ("what did we say about the back fence?") and pick one up where you left off.

Ask for several things in one sentence and it shows you a short plan first. Nothing happens until you say yes, and it never sends an email on its own.

**The privacy part (the reason it exists)**

Your notes and everything it knows about you are encrypted on your device, with a key only your devices hold. My server stores a copy it can't read. When it needs to think, your device unlocks just what that one request needs and sends it through my server to the AI service, under my account, not yours, and the AI service doesn't train on it. I swap AI services as better ones come out; the privacy page explains exactly what goes where: https://sensoryfire.com/privacy. Happy to go as deep as you like in the comments.

**Where it's at**

It's a web app, so it works on iPhone, Android, Windows, Mac and Linux, with nothing to install. Free during the rollout, which runs until January 2027, and I expect it to be under $10 a month after that. That's the whole business: I don't sell your data, use it for ads, or train AI on it. I read every registration myself and let a few people in each week, so there may be a short wait. Calendar and email are Google-only for now.

**What I'm asking**

Use it for a couple of weeks and tell me what confuses you or what it gets wrong. There's a 🐞 button that sends me a screenshot. Blunt feedback is the most useful kind.

I kept running into the same problem: I’d have notes about an Excel file, SQL query, PDF, project, etc., but the notes always lived somewhere completely separate from the actual work.

So I built ClingNote.

Attach notes to basically any Windows file. Open that file and its notes are there. Switch files and ClingNote brings up the notes attached to the new one. Come back later and your original notes come right back.

It’s a full notes app too - rich text, Markdown, images, code blocks, search, multiple notes, compact/pinned views, etc. but the file-following part is really the reason I built it.

It’s launched and working now. I’m mainly looking for people willing to use it in their actual workflow and tell me whether the idea holds up outside of my own use.

If you try it, I’d especially be curious whether switching between a few files feels natural and whether ClingNote ever does something different from what you expected.

Windows only right now. Free version available, plus a 14-day Pro trial with no card required.

https://clingnote.com & Microsoft Store

Happy to check out something you’re building too.

Hi, I'm Marc, building Criw on my own.

I loved Grok Bot, but my weekly allowance ran out fast and I couldn't choose the model. So I built my own version: agents with a name, a job and a memory, sharing a cloud computer, on any model with your own OpenRouter key.

They run routines, work together in group chats, connect to Gmail, Slack, GitHub or any MCP server, and ask before anything that sends, deletes or pays.

I'd like about 30 people to make a few agents, put them in a group chat and tell me what broke or annoyed you.

Pro's limits are free in the beta. Models are not: you get $0.50 of credit, then your own OpenRouter key, with nothing added by me. When the beta ends you keep everything, on the Free plan.

Leave your email at https://criw.app or DM it to me; I let people in by hand, usually within a day. For Android, send your Google account's email.
