What's new at darvin

Download posters and images as PNG or JPEG

The download button on every generated image now offers a choice of format. Grab the original WebP, or a full-resolution PNG or JPEG converted on the fly — handy for printing, pasting into design tools, or anywhere WebP isn't accepted.

Event poster generator for ancient-city trips

The visual agent can now create event posters, not just Instagram posts. The first series designs posters for ancient-city trips — Göbeklitepe, Ephesus, Gordion and more — in one locked, museum-grade house style so every poster in the series is unmistakably from the same organization.

• Type a destination and trip dates; the agent writes the tagline and art-directs the scene
• A locked, historic-and-mysterious design system keeps the whole series consistent
• Two image candidates per poster, reviewed in the admin before anything ships

Posters get richer inputs, an AI art-director, and logo uploads

The ancient-city poster generator levels up. A dedicated Posters tab now takes the full event details — dates, place, an optional subtitle, a free-text description of the feel you want, and any logos to include — and an AI art-director turns all of it into concrete design decisions before a single pixel is drawn. The result is a more original, better-composed poster every time.

• A dedicated Posters tab with full event inputs: dates, place, subtitle, a free-text "feel" box, and multiple logo uploads
• An AI art-director decides what to feature, how to light it for the feel you asked for, and where every element sits
• Sharper craft — one continuous, seamless background and a painstaking chiselled typography system kept consistent across the series
• Your uploaded logos are placed automatically in a clean row at the bottom, next to the Evrim Ağacı mark

Traffic on an interactive world map

The admin analytics Traffic view now plots geography on an interactive world map instead of a list. Shade countries by click volume, then flip a switch to see clicks as bubbles on the cities that drive them — with hover details, a legend, and a screen-reader data table.

Usage trends on the admin dashboard

The admin overview now charts how dar.vin is growing over time — clicks, links created, new sign-ups, and daily Instagram agent runs. Switch between metrics and zoom the window to 30 days, 90 days, or a full year to see the trend at a glance.

A full analytics hub for admins

The admin area now has a dedicated analytics hub. See traffic broken down by country, city, referrer and device; the visual-agent image pipeline's health; the link-in-bio funnel; link lifecycle; and how the daily Instagram posts drive clicks — all over a 7, 30, or 90-day window.

• Traffic breakdowns: countries, cities, referrers, devices, plus bot-vs-human and unique visitors
• Operational health: image-generation success rate and latency per provider
• Link-in-bio funnel, link lifecycle, and Instagram-driven clicks in one place

More image styles for the daily Instagram post

The visual agent now chooses from a library of meticulously art-directed image styles instead of a single look. An AI selector reads each Evrim Ağacı article and picks the style that fits its subject, so the daily post matches the topic.

• New wildlife, conceptual, cosmic, and portrait styles join the original macro look
• An AI selector matches the style to each article's real subject
• Built to keep growing: new styles drop in without touching the pipeline

One-tap review for the daily Instagram post

The daily visual agent now sends both the Gemini and ChatGPT image candidates, plus the proposed caption, straight to the team's Telegram for a one-tap decision before anything goes live.

• Pick the Gemini or the ChatGPT image and post it on the spot
• Reply with a new caption to revise before posting
• Reject to discard the run, all without leaving Telegram

Mobile system, end to end

A native-feel mobile pass across the entire product, from marketing to the dashboard: design tokens, mobile shells, and PWA polish.

• Bottom tab bar in the dashboard
• Mobile cards replace dense tables for Links
• Sticky save footer on form fields
• Theme color, status bar, and overscroll lock

Six-tab analytics portal

A full per-user analytics portal with KPI cards, sparkline, and tabbed deep dives, all powered by per-user TimescaleDB continuous aggregates.

• Overview, Links, Geo, Tech, Sources, Tags
• Live click ticker
• CSV export
• 7, 30, and 90 day windows

Bulk select and delete in admin tables

Every admin table now supports multi-select and bulk delete, with safety nets and undo where it matters.

Streaming WebP image route

Generated visuals are stored as thumbnail-aware WebP and streamed directly to admin clients, dropping bytes shipped for run reviews by an order of magnitude.

Visual Agent: AI image and caption pipeline

An end-to-end editorial pipeline that turns a fresh article into an Instagram-ready post: analyze, assemble prompt, generate image, write a caption, then a human review gate.

• Analyze, image, and caption stages with separate provider chains
• Free-tier image generation through subscription browsers
• Per-stage variants and resume from any step
• Live worker heartbeat, force-fail, and one-click sweep
