Design a virtual host or start from a photo, record or upload clips of your voice in any of 21 languages, and Scro keeps that face, outfit and voice the same in every video. You approve the storyboard (hook, scenes and narration) before rendering 30 to 60 second vertical cuts for Reels, Shorts and TikTok, and the same character also appears in daily-life photo posts and product UGC. Plans start at $59 a month, and new accounts get 80 free credits.
Upload the photos you might use and Enhance.Dating's AI ranks them, explaining what works and what drags the profile down. Bio Builder interviews you and drafts an about-me in several tones, Message Helper suggests openers from a match's profile or a chat that went quiet, and Profile Review adds feedback from real members of the opposite sex. The AI tools are free to start, and the site works in 20 languages, Turkish included.
PiScan requests your page with the user agents of 16 AI crawlers, including those of ChatGPT, Claude, Perplexity and Gemini, and compares what robots.txt allows with what the server actually does. It then scores the page in five weighted layers: access, extractability without JavaScript, self-contained passages, structured data and citability. No signup, three scans a day, results in about 15 seconds. A DijitalPi product.
FacialHarmonyAI maps facial landmarks from a single front-facing photo and describes symmetry, facial thirds, eye balance and golden-ratio relationships instead of giving one attractiveness score. Detection runs in the browser, so the photo is not uploaded. The preview is free; the full report covers 30 frontal measurements and costs $9.99 once.
Pick your GPU or Apple chip, RAM, operating system and main use, and BestLLMfor lists the open-weight models that fit, with the VRAM each one needs at Q4 and an estimated speed. The catalog covers chat, coding, vision and audio models, and step-by-step guides cover Ollama and LM Studio. The configurator, catalog and guides are free with no sign-up; paid kits for specific setups cost $24 each or $49 for all of them.
Upload a full-body character on a white background, pick a motion such as idle, walk, run, attack or jump, and SpriteFrame generates the frames, removes the background and lays them out as a sprite sheet. Separate free tools build sheets from your own PNG frames or MP4 clips in the browser, without an account. Exports are PNG sheets or PNG frames with JSON timing data; AI animation runs on credits, with 30 free credits to start and plans from $12 a month.
Avenyora calculates your birth chart with an astronomy engine, then uses AI to interpret it alongside numerology cycles, tarot draws and the relationship questions you bring. Long-term memory stays off until you turn it on, and every saved memory can be edited or deleted. Birth chart, moon sign, compatibility, tarot and numerology tools are free without sign-up; a free account gets 3 AI replies a day, and Premium costs $9.99 a month or $69.99 a year.
BeadPattern turns a photo or a text prompt into a Perler, Hama or Artkal bead pattern. The result is an editable grid with colors matched to the chosen bead brand and a bead count for each color, exported as a PDF or PNG template. Free users get 3 watermarked downloads a month, with paid plans above that.
Upload manga pages as images or a PDF and pick the source and target languages. AI Manga Translator finds the text in each speech bubble with a comic text detector, translates it, and fits the translation back into the same bubble. New accounts get 10 free credits; after that each page costs 10 credits, and failed pages are refunded automatically.
HyperWrite is an AI writing assistant offering hundreds of built-in tools for composing, editing, and researching content across platforms. The Chrome extension integrates with Gmail and Google Docs to provide real-time suggestions and email automation. Premium plans unlock custom AI personas and advanced features for writers, students, and professionals.
Scribbly is a Chrome extension that uses AI to help you compose and respond to emails effortlessly. It analyzes incoming messages and suggests personalized responses matching your tone and communication style. Designed for Gmail and Outlook, it's built for sales professionals, support teams, managers, and anyone who spends hours on email.
Upload a photo or drawing of your hero once, approve the character sheet, and ComicStory AI keeps that face across every panel and page. Write a single line, a script or a book chapter, choose a style such as manga, anime, American, watercolor, chibi or noir, then edit the speech bubbles, redraw single panels and export a print-ready PDF. Sign-up gives 50 one-time credits; paid plans start at $12.99 a month for 700 credits.
