AI Tweet Composer
Model:
Compose a single tweet (280-char limit enforced) with tone, hashtag count, and link-inclusion controls. Switch to 3-variant mode to A/B-test three angles side by side — each gets its own copy button and X-intent link so you can post in one click. Built for the 280-char X limit, not for LinkedIn posts or thread starters.

Free.ai Tweet Composer writes a single tweet (280-char X limit enforced live as you type) with tone, hashtag count, and link-inclusion controls. Switch to 3-variant mode for A/B/C versions side-by-side, each with its own Copy button and X-intent link so you can post in one click.
Yes — Qwen 2.5 7B on our GPUs, about 100-300 tokens per tweet inside the daily pool. Signed-in free accounts get 10,000 tokens on signup, enough for dozens of tweets or a month of daily posting.
Typefully is $29/month, Taplio $39/month, Hootsuite AI $99+/month — all gate tweet generation behind subscriptions. Free.ai composes tweets for free, returns 1 or 3 variants, enforces the 280-char limit live, and provides X-intent posting links. No seat fees, no monthly commitment.
X counts URLs as 23 chars regardless of actual length (via t.co shortener), and emojis usually count as 1-2. Our live counter replicates X's counting logic so you know BEFORE posting whether the tweet fits. Red = over 280, orange = 261-280 (tight), green = under 260.
Eight tones: Witty, Hot take / contrarian, Educational / insightful, Humble flex, Storytelling, Question / engagement, Professional, Meme / funny. Each is system-prompted separately for distinct voices.
Three distinct angles on the same topic — one punchy, one contrarian, one question-form. Each is labeled A/B/C and sits in its own editable card with a copy button and "Post on X" intent link. Useful for finding which angle resonates before you post.
No — compose your first tweet immediately, no email, no credit card. Sign up free for 10,000 signup tokens, generation history, and save drafts.
Yes — the output is a live-editing textarea with the character counter updating as you type. Tweak the wording, swap a hashtag, shorten a URL — all before hitting "Post on X".
Not directly — this tool composes a single tweet. For thread-style content, compose each tweet separately (each ≤280 chars) and paste them into X or Typefully's thread composer. Multi-tweet thread generation is on our roadmap.
Yes — the "Audience" field tunes the voice for indie founders, crypto devs, marketers, etc. Combined with the tone picker, you get audience-native tweets (hacker voice for devs, analyst voice for finance Twitter).
Yes — all 99 languages Free.ai supports. Type your topic in Spanish / Japanese / Turkish and the tweet comes back in the same language, still under 280 chars.
Yes. POST to /v1/chat/ with the tweet-composer system prompt. Useful for scheduling tools building tweet-generation features. Bearer auth, monthly limits. See /api/ for snippets.
