Medium TK is a free AI writing notebook that publishes to Medium. Kompozy is the alternative for creators who generate and publish across every platform.
Medium TK is a good tool, and this page is not here to talk you out of it. Launched November 9, 2026, it is a free in-editor AI writing app: you type "@TK" inside the draft and get research lookups, editing, style matching, headline feedback, and style-guide checks, plus provenance notes that disclose how AI was used in a piece. If your job is drafting a better Medium essay with transparent AI use, TK is excellent and costs nothing.
This page exists because a lot of people reach for "the best AI writing app" when the problem they actually have is distribution, not drafting. TK improves one piece of writing and publishes it to exactly one place — Medium. It generates no video, images, carousels, or newsletters, posts to no social platform, and has no scheduler. For a solo essayist that is fine. For a creator, brand, or agency running content as an operation, the draft is the easy 10% — the work is turning it into the formats every feed wants and getting it published across all of them.
Kompozy is the alternative for that second group. It is not a drafting notebook; it is a content generation and publishing engine that takes a source — including a draft you wrote in TK and exported as Markdown — and fans it into 18 formats across an owned blog plus eight social platforms and email, under one brand voice, with scheduling and a per-post review gate. The honest question: do you need a better way to write one Medium post, or a way to stop being a single-destination, text-only creator?
Medium TK is Medium's free, web-based writing app (a desktop app is on the roadmap). Its core is a standalone editor with an AI assistant invoked by typing "@TK" in the draft — it runs quick research lookups, helps with editing and style matching, recalls writing you saved earlier, suggests prompts, gives headline feedback, and checks a draft against a Medium publication's style guide. It adds a social layer for sharing early drafts and getting feedback, imports and exports Markdown (though it is not itself a Markdown editor), and lets you set access permissions, though writing in it is not encrypted because it is built for collaboration. Two standout features: it can connect to your own AI agent via an MCP server or a Claude skill so your agent's memory informs a draft, and authors can publish provenance notes disclosing how AI was used. What it does not do is generate non-text content or publish anywhere but Medium — it is a drafting layer for a single destination, and a well-made one.
The reason to look past TK is not that it is weak — it is that it answers a narrow question. First, it is single-destination: it improves and publishes a Medium post, and that is the entire distribution story. Second, it is text-only: no video, image, carousel, quote graphic, or newsletter, so a modern content mix is mostly out of reach. Third, it does not schedule or publish across platforms, so even the prose it helps you write still has to be manually reshaped and reposted everywhere else by hand. Fourth, it has no brand governance across a batch — the style match helps one piece at a time, not a week of mixed outputs that all need to sound like one brand. For a Medium-first essayist, none of this matters. For anyone whose reach depends on showing up across TikTok, Reels, Shorts, X, LinkedIn, a blog, and an inbox, the leverage is downstream of the draft — in generation and distribution, which is a different product.
| Feature | Medium TK | Kompozy | Note |
|---|---|---|---|
| In-editor AI drafting assistant | Yes — the @TK assistant | Generates drafts, not in-editor | TK's core strength is in-flow help while you write prose. Kompozy generates finished copy from a source rather than assisting live in an editor. |
| AI provenance / transparency notes | Yes — signature feature | Per-post human review gate | TK publishes a note disclosing AI use. Kompozy keeps a human in the loop differently — you approve each generated piece before it ships. |
| Multi-format generation | No — text only | Yes — 18 formats | The core gap: TK writes prose; Kompozy makes Persona Shorts, Clipped Shorts, carousels, images, blogs, and newsletters. |
| Video generation (avatar / clips) | No | Yes — Persona Shorts, clipping | TK produces no video. Kompozy generates avatar-narrated shorts and clips long footage into vertical cuts. |
| Carousels & brand-exact graphics | No | Yes — HyperFrames | TK makes no visual assets. Kompozy renders brand-exact carousels and quote cards through HyperFrames. |
| Multi-platform publishing | Medium only | Blog + eight social platforms + email | The decisive difference — one destination vs a pipeline that publishes everywhere you post. |
| Scheduling & autopilot | No | Yes — Autopilot | TK has no scheduler. Kompozy schedules into your active windows and publishes on autopilot behind a review gate. |
| Brand voice across a batch | Partial — per-piece style match | Yes — Persona Brief governs every output | TK matches style one draft at a time; Kompozy holds a whole week of mixed formats to one voice. |
| Connect your own AI agent | Yes — MCP server + Claude skill | Built-in generation models | TK can pull in your agent's memory. Kompozy runs its own Claude/OpenAI/Gemini/HeyGen stack to produce content. |
| Markdown export | Yes | Accepts it as a source | TK exports Markdown; Kompozy ingests a TK draft as a source to expand into every format. |
| Collaboration & draft sharing | Yes — social feedback layer | Per-post review workflow | TK is built for collaborative drafting. Kompozy's collaboration is a review pipeline over generated content. |
| Price | Free | Paid | TK is free for any Medium account. Kompozy is a paid generation-and-publishing platform. |
| Tier | Medium TK plan | Medium TK price | Kompozy plan | Kompozy price |
|---|---|---|---|---|
| Entry | Medium TK | Free | Kompozy Starter | $199/mo (5,500 credits) |
| Mid | Medium TK (same app) | Free | Kompozy Pro | $499/mo (18,000 credits) |
| Top | Medium membership | ~$5/mo (reader/writer membership, separate from TK) | Kompozy Agency | $999/mo (55,000 credits) |
The cleanest way to see the difference: Medium TK makes the *draft* better; Kompozy makes the draft *travel*. They are not really rivals — many writers will use both, drafting in TK and then expanding the result. But if you are choosing one tool to solve "I need content out across platforms," a drafting notebook locked to Medium is the wrong shape of tool.
[Kompozy](/) takes a single source — a draft, a transcript, a hot take, or a TK export — and generates the formats one essay can't be: a blog article and an email newsletter, brand-exact carousels and quote cards via HyperFrames, platform-native text posts, and an avatar-narrated Persona Short, with clipping for anything long-form. Every piece is held to your Persona Brief so the set sounds like one writer, you approve each one behind a per-post review gate, and Autopilot schedules and publishes the whole batch across the eight social platforms plus blog and email. For creators who publish text-first, see the honest [Jasper alternative](/alternatives/jasper), [Substack alternative](/alternatives/substack), and [Grammarly alternative](/alternatives/grammarly); for the full read on TK itself, see the [Medium TK review](/reviews/medium-tk). TK writes for one place. Kompozy produces and distributes for every place your audience already is.
It depends on the job. For drafting a Medium essay, TK is excellent and free — there is no "better" general replacement. For producing and distributing content across platforms, Kompozy is the alternative: it generates 18 formats from one source and publishes across a blog plus eight social platforms and email, which TK does not do.
TK is a free in-editor AI writing app that improves a draft and publishes it to Medium. Kompozy is a content generation and publishing engine that turns one source into video, images, carousels, blogs, and newsletters and publishes them across nine destinations under one brand voice. One drafts; the other produces and distributes.
Yes. Export the draft from TK as Markdown and paste it into Kompozy as a source. Kompozy then expands it into a blog, newsletter, carousels, text posts, and a Persona Short, all governed by your Persona Brief, and schedules and publishes them.
No. TK is free for any Medium account; Kompozy is a paid platform because it generates multi-format content (including video) and publishes across nine destinations. They solve different problems at different price points.
No — TK publishes only to Medium. To distribute writing across TikTok, Instagram, YouTube, X, LinkedIn, a blog, and email, you need a generation-and-publishing engine like Kompozy.
