Generates Facebook posts across 9 distinct post types (text status, photo caption, Reel / video, event announcement, product / promo, poll / question, personal story, business page, group post). Each output ships 3 variants — SHORT (under 80 chars) / MEDIUM (3-5 lines) / DETAILED (paragraph / mini-essay) — so you can pick the length that fits your campaign goal. Tuned for Meta's 2024 algorithm: hook in line 1, no engagement-bait phrases, optional 3-5 niche hashtags.
Hootsuite is $99-249/mo. Buffer $6-12/mo per channel. Sprout Social $249+/mo. Later $25-80/mo. Meta Business Suite is free but only schedules — no AI writing. All are scheduling tools with AI as a side feature. Free.ai is purpose-built for caption craft (9 post-type pills, Meta-algorithm-aware system prompts, banned-engagement-bait list, 3 length variants). Free.
Yes — Qwen 3 30B on our GPUs. 3 variants of any post type cost about 400 tokens. Free signup gets 10,000 tokens — ~25 sessions. Premium models (Claude Sonnet, GPT-5) write punchier hooks worth the swap when you're paying for boost / paid-distribution.
(1) Text post — plain status, no media. (2) Photo caption — single image post. (3) Reel / video description. (4) Event announcement — date/time/location/RSVP CTA. (5) Product / promo — offer + price + scarcity + link. (6) Poll / question — open-ended (gets 100% more comments per Buffer 2024). (7) Personal story — narrative arc with concrete detail. (8) Business page post — value-first thought leadership. (9) Group post — community-aware, follows group rules.
No — banned phrases include 'Like and share if you agree', 'Comment YES below', 'Tag a friend who needs this', 'Drop a 🔥', 'Double tap if'. Meta's algorithm has actively deboosted these since 2017 — using them lowers your reach. The system prompt enforces softer CTAs (RSVP, DM, link in bio, share, comment your take).
Different posts need different lengths. SHORT (under 80 chars) gets the highest engagement rate per character but limits info density. MEDIUM (3-5 lines) is the sweet spot for most posts. DETAILED (paragraph+) is for stories, business thought-leadership, or detailed event announcements where readers will see the value of expanding 'See more'. Pick the length that fits your goal.
Yes — toggle "Open with a question (boosts comments)". Per Buffer 2024 data, posts opening with a genuine open-ended question get 100% more comments. Note: rhetorical questions or yes/no questions do NOT count as engagement-bait if they invite real responses.
Toggle 'Add 3-5 niche hashtags' to append niche-specific hashtags at the end. The prompt avoids generic broad tags (#love, #motivation) which dilute reach. Niche hashtags target audience size 1K-100K — sweet spot for genuine discovery on Facebook (less algorithmic than Instagram but still useful for Pages and groups).
No — first session free. Sign up for 10K tokens, generation history, premium models. ~25 sessions per signup grant.
Yes — describe your post in Portuguese, Hindi, German, etc. and posts return in the same language with regionally appropriate emoji and idioms. Particularly useful for non-US Page admins reaching local communities.
No — the system prompt explicitly forbids it. Missing data triggers placeholders like [start time], [ticket link], [event location]. Search-and-replace before posting. Critical for product / promo / event posts where wrong data tanks trust.
Yes — POST to /v1/chat/ with the Facebook post system prompt (in template source). Useful for content-scheduling SaaS, agency client deliverables, or e-commerce platforms auto-generating product post copy. Bearer auth, monthly limits. Docs at /api/.
