  • Important

    Sign in with your email address or Google

    Signing in and signing up to GrowX now use your email address or Google, and signing in with X has ended. After signing up, connect X as a social account.

  • New feature

    GrowX is now available in English

    The app, announcements and AI responses are now available in English. English pages are under /en, and you can switch the display language in Settings.

  • Update

    A faster home page

    We reduced the data loaded when you open the home page so it shows up faster. Page content appears right away without waiting for everything to load, and news details load only when you open them.

  • Update

    A fresh look for the home page and every other page

    We rebuilt the home page with a calmer, more spacious design. The full list of features now lives on the Features page. The Pricing, Use cases, Help, Contact, and Terms pages share the same look, and the Pricing page lets you compare plans with cards and a comparison table.

  • Notice

    We have strengthened security

    We reviewed security across the service and strengthened protection, focusing on sign-in, session management, team permissions, and payments. Signed-out sessions are now invalidated immediately, and signing in on another device no longer affects your existing sessions. Teams now control more strictly what each member can do based on their role.

  • Update

    A new monthly view for the scheduling calendar

    We rebuilt the scheduling calendar as a monthly view that shows published posts, scheduled posts, and open posting slots as cards for each day. Editing scheduled posts and threads now uses the same "write on the left, preview on the right" layout as compose, and you can check and replace attached images in the preview.

  • Notice

    Usage limits for AI and generation features

    To keep AI, image generation, and video generation running reliably, we have reorganized usage limits. The help chat allows up to 30 messages per day. Automatic memo tagging is available on Pro and above, up to 50 times per day. Reprocessing post themes (clusters) is available on Pro and above. On the Premium plan, image generation (200 images per month) and video generation (20 videos per month) are now counted accurately, including generations that run at the same time. Uploading video assets is available on the Premium plan, up to 10 images and 10 audio files.

  • Update

    A redesigned dashboard

    Key metrics such as impressions, engagement rate, and net follower growth are now grouped at the top, with clearer comparisons to the previous period. The post ranking is now a comparison table showing each post's text alongside its metrics, and the chart lets you pick the metric whose trend you want to see. From the chart or the ranking, you can jump straight to the post list or time analysis for the same period.

  • Notice

    Updated team permissions and account switching

    Team writers can no longer publish or write directly through scheduling or the AI agent. Instead, they work through drafts and the approval flow. Only the owner can grant the admin role or deactivate a team. When the owner's paid plan ends, the team is paused (the owner can still manage it). The account switcher now lists only the accounts you linked with "Add account".

  • Update

    A compose screen built for focused writing

    We moved the compose preview to the right so you can see how your post will look as you type. The character count now appears as a circular meter like on X, and the 140-character limit for free accounts is checked the same way X counts it (for example, a Japanese character counts as 1 and a letter or digit as 0.5). We also tidied up the toolbar, how threads start, and the order of the save and schedule buttons.

  • Update

    Major upgrade to reference posts: saved data, list view, and CSV export

    We have significantly upgraded reference posts. The text, author details, like count, and conversation count of each saved post are now fetched and stored automatically. A new list view joins the card view, and sorting, date filters, and text search make it much easier to browse. Media previews with zoom, CSV export, and X search integration are also included.

  • New feature

    Visual analytics for ego search

    We added visual analytics to ego search. See the full picture of mentions for a keyword with data: mention trends over time, a topic map (topic distribution), author attributes (follower size, region, posting device, and account age), frequent words, and more. You can also narrow the period to analyze how trends change over a specific time.

  • Notice

    About quote and repost features

    Due to X API restrictions, quotes and reposts can only be made on your own posts. Quoting or reposting other users' posts is not supported. Thank you for your understanding.

  • New feature

    Introducing team features

    We released team features to help you run an X account as a team. Writers create drafts for the owner's X account, and approvers review and approve them. Role-based access control (owner, admin, editor, writer), an approval queue, comments, and an activity log keep team operations transparent. Creating a team requires the Premium plan, and anyone can join a team, including on the Free plan.

  • Update

    A major upgrade to the AI agent

    We have significantly improved the AI agent. It now handles requests that combine research and writing, such as "Look up trends and draft some posts", and generates drafts based on real data. A loop that automatically evaluates and improves generated posts is also in place. The agent's reasoning and tool steps are now saved in the conversation history, so when you look back you can see what it researched and how it thought.

  • New feature

    Introducing scheduled reposts

    We released scheduled reposts, which repost (retweet) automatically at the date and time you choose. Just enter the URL of the post you want to repost on the compose screen and set a time. Reshare posts that performed well or repost at strategic moments.

  • New feature

    Introducing AI video generation

    We released AI video generation, which automatically creates short videos from your post content. Create videos with captions from text and images to make your posts even more striking. Available only on the Premium plan.

  • New feature

    Introducing AI image generation

    We released AI image generation, which automatically creates eye-catching images that match your post. Turn text into the right visual to make your posts stand out. Available only on the Premium plan.

  • New feature

    Research added to the AI agent

    We added research to the AI agent so it can search external sources. It supports 9 sources, including academic papers (OpenAlex, arXiv), tech news (Hacker News), communities (Reddit), an encyclopedia (Wikipedia), open source (GitHub), trends (Google Trends, YouTube), and Japanese news.

  • New feature

    Introducing Before/After for measuring the impact of changes

    We released Before/After, which lets you measure the impact of changes you want to try, such as new posting times, writing styles, or hashtag strategies, with numbers. Just set a start date to automatically compare impressions, engagement rate, likes, and more between the periods before and after. It includes change-rate charts, trends over time, time-of-day analysis, and PDF report export.

  • New page

    The Use cases page is live

    We published a page that walks through how to use GrowX by use case. It covers specific ways to use GrowX in two categories: for individuals (growing your reach, self-analysis) and for businesses (social media marketing, competitor analysis).

  • Update

    Better post performance analysis

    We added a post type filter (original, replies, quotes) to the post performance page. Use the checkboxes to choose which post types to show. The charts update to match the filter, and your settings are saved in your browser.

  • New feature

    Introducing structure pattern analysis

    We released structure pattern analysis, which turns the writing structure of high-engagement posts into patterns and visualizes them. Find out why your best posts resonated by looking at how they were put together. It also explains when each pattern works best, with concrete steps.

  • New feature

    Introducing ego search

    We released ego search, which lets you register keywords and search posts on X. Check how people on X are reacting to your brand, product, or topics you care about. It includes an option to exclude your own posts, and search limits vary by plan.

  • New feature

    Introducing competitor benchmarks

    We released competitor benchmarks, which let you register competitor accounts you're curious about and analyze their posting patterns. Along with charts of posting trends, AI-powered theme analysis, differentiation suggestions, and analysis of what drives high engagement support your posting strategy with data.

  • New feature

    Introducing posting slots

    You can now save recurring posting times, daily or by day of the week, as posting slots. Just pick a posting slot when composing and the next posting time is set automatically. A randomize option (± minutes) makes your posting times look natural.

  • Important

    Improvements to media uploads (v0.5.1)

    We made video and image posts more reliable. Animated GIFs are currently not supported due to technical limitations. We will keep working to make posting media even more reliable.

  • Update

    The AI agent has evolved (v0.5.0)

    The AI agent is now adaptive. It learns from past successes and failures to respond more intelligently. The more you use it, the better it understands your posting style.

  • Coming soon

    Integrations with external apps are on the way

    We plan to build integrations with popular apps such as LINE Notify, Notion, Google Calendar, Slack, and note. They will fit seamlessly into your existing workflow and make GrowX even more convenient.

  • New feature

    Introducing quotes

    We released quotes, which let you post while quoting another user's post. Quotes work for both immediate and scheduled posts. Just paste an X URL to create a quote.

  • Release

    GrowX AI agent V1 is here

    We released an AI agent that works with every GrowX feature. It analyzes your post data, stats, and memos together and supports your posting process, from suggesting drafts to scheduling posts. Use it as a partner that truly understands your posting.

  • Updated

    A redesigned landing page

    To coincide with the release of the GrowX AI agent, we have completely redesigned the landing page. A clearer design and structure show what GrowX offers, and new features and improvements are easier to find.

  • New feature

    Introducing threads (v0.3.0)

    We released threads, which let you post multiple posts as a reply chain (thread). Threads work for both immediate and scheduled posts.

  • Progress

    GrowX AI agent: development on track, solving "I can't make the most of the dashboard"

    "I look at the analytics dashboard but don't know what to analyze." "There's too much information." "I'm not making the most of my data." We hear you. The AI agent understands all of your data as a whole. It can help with scheduled posts and work with you on new post ideas from your past memos. Move beyond analyzing a skewed slice of your data toward truly data-driven posting. Stay tuned.

  • In development

    GrowX AI agent in development

    We are building an AI agent that works with every GrowX feature. It will refer to your post data, stats, memos, and posting focus to support your posting. Stay tuned.
