Chrome Extension for InstagramInstagram on desktop, the way it should be.
Post photos, reels, stories, and carousels from your computer. Schedule a month at a time. Generate captions that actually know what your AI image was. Run every account from one tab.
Add to Chrome
From an idea to a post in under a minute
Generate the image with the AI you already use. Opalite holds the original prompt next to it. When you open Instagram, the composer is already filled in, caption and all.
The Opalite library sits between them, automatically. You never have to re-upload an image.
Everything an Instagram client should do, plus the parts nobody else does.
The desktop client features are free forever. The AI side is on the Plus plan.
Post anything from desktop
Photos, carousels up to 20 slides, Reels up to 15 minutes, Stories, IGTV. Drag and drop straight from Finder.
Schedule with a real calendar
Plan a week, a month, a launch. Drafts auto-publish at the time you set, even when your laptop is closed.
Captions that know what you made
When the image came from Grok, Gemini, or ChatGPT, the original prompt rides along. Your captions stop sounding generic.
Hashtag assistant
Research, save, and reuse hashtag sets. Tune the popular vs niche mix per profile so reach and relevance both win.
Multi-account switching
Sign into every account once. Switch instantly. Your active handle drives the captions, hashtags, and voice without you thinking about it.
Direct messages, templates, and ghost mode
Reply faster with reusable DM templates. Browse stories without your view appearing in anyone’s list.
Your accounts. Your voices. Your rules.
When you run four Instagram accounts, the AI starts to drift. Same captions. Same emojis. Same rhythm. Per-account profiles fix that. Each handle gets its own tone, length, brand voice, hashtag rules, even its own forbidden topics.
- One profile per accountEvery Instagram handle you sign into gets its own settings: tone, length, brand voice, hashtag rules, emoji policy, custom prompt.
- Auto-detectedWhen the extension sees you switch to @other_handle, the matching profile takes over. No menus, no manual swap.
- Bulk regenerateChange the rules on a profile, hit one button, and every draft for that account gets rewritten in seconds.
- Brand voice with examplesPaste 5 to 50 of your existing captions. The AI learns your phrasing and writes new ones that sound like you, not like ChatGPT.
Captions that know what you made.
Other tools see a JPEG and guess. Opalite reads the brief that made it. When the image came out of Grok, Gemini, ChatGPT, or Sora through one of our suites, the original prompt rides along. Captions reference what you actually generated.
Five built-in tone presets. Brand mode learns from 5 to 50 of your existing captions.
The full Instagram surface, on a real keyboard
DMs, story viewing, follower analytics, hashtag research. Nothing about the desktop experience feels like a phone app squeezed sideways.
DMs with templates
Reply faster with reusable message snippets. Categorize by audience: collabs, customer support, fan replies.
Looks right at any width
Resizes from a side panel to full screen. Same UI works whether the extension is pinned narrow or wide open.

No password. No API key. No third-party login.
The extension runs inside the Instagram tab you’re already signed into. If you can post in instagram.com, you can post here.
In your session
No OAuth pop-up, no Meta partner status. The actions go through the same web channels Instagram exposes to its own client.
No bot behaviour
No mass-likes, mass-follows, or scraping. Posting, scheduling, and DMs run at human cadence by design.
Captions opt-in
Image data only leaves your machine when you ask for an AI caption, and only the image and prompt are sent to Google Gemini for the call.
Free for the part everyone wants. Plus for the AI.

The questions everyone asks
Is this really free?
Posting, scheduling, hashtag tools, multi-account, DMs, ghost mode: all free, no trial timer. The AI caption tier (Plus) is $5/month and unlocks per-account voice profiles, bulk regenerate, and prompt-aware captions.
Do you ever see my Instagram password?
No. The extension runs inside your existing Instagram browser session. There is no API key, no OAuth pop-up, no third-party login. If you can post in instagram.com, you can post here.
Will Instagram ban my account?
The extension acts the way you would. It never spam-likes, mass-follows, or hits Instagram faster than a human could. Posting, scheduling, and DMs use the same channels Instagram already exposes to its own web app.
What makes the AI captions different from Buffer or Later?
When the image came from Grok, Gemini, or ChatGPT, we keep the original prompt next to it. Your captions can reference what you actually generated, not a generic vibe guess. Other tools see a JPEG; we see the brief that made it.
How many accounts can I run?
Up to 5 Instagram accounts on one Opalite plan. Each gets its own profile so the captions stop drifting between brands.
Which browsers are supported?
Any Chromium browser: Chrome, Brave, Arc, Vivaldi, Edge, Opera. Safari and Firefox are not yet supported.
