What it is
Tell the Universe is a minimalist space to release a thought. A short message becomes a floating glowing post, drifting among other anonymous signals in a small digital universe.
The project is intentionally restrained: short posts, calm visuals, moderated content, and no social-performance machinery.
Why it exists
Not everything online has to accelerate. Not every post has to become content. Not every thought needs a profile, a metric, or a strategy.
TTU is built as a quiet alternative to feeds that rank, optimize, and pull attention into endless loops. Here, a post is not a performance unit. It is a small signal released into space.
How it works
- Write a short message and submit it. It becomes a floating post in the universe.
- Floating posts are limited to 100 characters and may include one optional JPG or PNG image up to 5 MB.
- Posts can be text-only, image-only, or a combination of both.
- Each post can open a dedicated reply page where visitors can write longer responses and add one optional image.
- Floating post controls are split into two rows: the muted upper row shows date and shooting-star rating; the brighter lower row shows Cosmic Echo, Reply, and Share.
- The global Cosmic Answer button sits at the top center and creates a collective AI reflection from all current floating posts.
- The share function can turn a floating post into an image for use outside the platform.
Cosmic Echo
Cosmic Echo is the temporary AI reflection layer of TTU. It is not a chatbot and not a human reply.
When invited by clicking Cosmic Echo, it creates one short atmospheric response to a text post, appears somewhere on the screen for about 30 seconds, and then disappears.
After the echo has faded away, the button becomes available again and another signal can be generated, subject to rate limits. Echoes are clearly marked, temporary, and do not become permanent public replies.
Cosmic Answer
Cosmic Answer is the global reflection layer of TTU. Instead of reacting to a single post, it listens to the current constellation of all floating posts and creates one compact collective answer.
The button is placed at the top center of the universe. A visitor can activate it up to five times per day, based on a hashed IP check and subject to short-term rate limits.
Like Cosmic Echo, the answer appears temporarily, does not become a permanent public reply, and is clearly marked as an AI-generated atmospheric signal.
DOGMA
- Anonymity by design: TTU does not use accounts, profiles, follower graphs, or public user identities.
- Small signals: floating posts are deliberately short and visually limited.
- Open replies: replies give more space without turning the platform into a conventional social feed.
- Moderation: content may be reviewed and removed to preserve a calm, high-quality space.
- Shareable fragments: posts can travel beyond the platform as images or fixed reply-page URLs.
- Antidote to the algorithm: TTU follows the idea of a cabinet of curiosities — a slower, stranger, more human counter-form to optimized feeds.
Privacy & data
- No account is needed; there are no public user profiles.
- Posts, replies, and uploaded images are public content. Avoid sharing sensitive personal data.
- Shooting-star ratings store a count per post and use a hashed IP check to reduce repeated voting. Raw IPs are not stored for this purpose.
- Cosmic Echo is optional. Only when the button is clicked is the selected post text sent to an external AI service for moderation and generation.
- Cosmic Answer is optional. Only when the global button is clicked are the current floating posts sent to an external AI service for moderation and generation.
- Cosmic Echo and Cosmic Answer responses are temporary on the frontend and do not reappear after reloading the page.
- Technical request data may be processed for security, moderation, abuse prevention, rate limiting, and server operation.
- Basic server logs may exist briefly for security and maintenance.

Moderation
Content that is illegal, hateful, harassing, doxxing, spam-like, or otherwise destructive to the atmosphere of the project may be removed.
The aim is not volume for its own sake, but a distinctive stream of brief, strange, sincere, or meaningful signals.
Tech bits
- Frontend: vanilla JavaScript with floating post rendering, image previews, temporary AI-reflection windows, and a canvas-based universe background.
- Backend: lightweight PHP endpoints with upload validation and server-side AI calls.
- Storage: SQLite for posts, replies, image metadata, ratings, operational Cosmic Echo records, and daily Cosmic Answer activation records, plus public image files on the server.
- AI layer: Cosmic Echo and Cosmic Answer are generated through an external language-model API. API keys are kept on the server and are never exposed to the browser.
