Best Eightify Alternatives in 2026

Eightify is a polished YouTube-only summarizer. It does one thing well — injects a clean summary panel into the YouTube watch page with timestamps and translation across many languages, powered by ChatGPT and Claude under the hood. So why are people looking for Eightify alternatives?

Three common reasons. The free tier is tight — daily caps hit faster than expected for heavy viewing days. Subscription friction — the paid plan's renewal terms and cancellation flows are worth verifying before committing. YouTube-only scope — when Anya's research workflow expands from YouTube to industry PDFs and articles, or when Cleo's study materials include lecture slides as well as recorded talks, Eightify can't follow.

This roundup compares Eightify alternatives that either keep the YouTube workflow polished while adding more source types (Reduz, NoteGPT), or offer a more generous free tier on YouTube specifically (Glasp YouTube Summary), or bring multi-tool browser-assistant breadth (Sider, HARPA). Reduz appears in the list because Reduz is one of the products in the category — see the methodology box for what each tool was judged on.

Why look beyond Eightify?

Eightify is fine for the YouTube-only user who watches one or two videos a day on the free tier or pays the hosted plan without issue. The reasons to look beyond it are specific. Free-tier fatigue: the daily cap is small enough that a free user can't reliably summarize three videos in an afternoon. YouTube-only scope: when Anya wants to summarize the article a video cites or the PDF the speaker referenced, Eightify can't help — she's back to a second tool. No your own AI key support: even at the paid tier, Nico can't route the transcript through his own Anthropic key. The best Eightify alternative depends on which of these is the deal-breaker.

The list

AI summarizer

Reduz

Reduz turns whatever you have open in Chrome into a clean summary: YouTube videos, PDFs, articles, webpages, and selected text. Use your own key from OpenAI, Anthropic, Google, DeepSeek, or xAI for unlimited use, with the key stored in Chrome on your device. Or start with 100 free credits a month, no card needed. Every summary saves to a searchable local history. Export to PDF, Markdown, or ZIP.

Best for:People who summarize YouTube videos, PDFs, articles, and webpages in Chrome and want to use their own AI key or start with free credits.

Fits Anya scanning competitor articles, Theo working through research papers, and Nico routing requests through a personal Anthropic key. Same extension, no account needed when you use your own AI key.

Strengths

Works on YouTube videos, PDFs, articles, webpages, and selected text from one extension.
Use your own AI key across OpenAI, Anthropic, Google, DeepSeek, or xAI. Keys stay on your device.
History, settings, and exports are local. Cloud backup is opt-in.

Tradeoffs

Focused on summaries. Not a chat assistant or browser automation tool.
AI generation still uses your selected provider in the cloud (local-first, not offline-only).

How to get started

Install Reduz from the Chrome Web Store.
Pick your own AI key or free credits in the first-run chooser.
Open the YouTube video, PDF, or article you want to summarize.
Click the Reduz toolbar icon.
Save, export, or copy the summary. Local history keeps it searchable.

Pricing:Free with 100 credits a month, no card. Using your own AI key is unlimited at provider rates (typically cents per article). Pro is $3/mo for 1,000 credits, Premium is $9/mo for 5,000 credits.

Transcript and YouTube summary extension

Glasp YouTube Summary

Glasp's YouTube Summary extension is a popular YouTube summarizer. Its meaningful difference from the rest of the field is that the basic flow works with no sign-up required. Users pick which model processes the transcript (ChatGPT, Claude, Gemini, Mistral). The Glasp web app upsells highlighting, social-style learning, and a public profile around saved highlights, which is a separate decision from the extension itself.

Best for:Users who want quick YouTube transcript access, ChatGPT or Claude summaries, and optional Glasp reading workflows.

Good fit when YouTube is the main reading surface and creating one more account is the dealbreaker. Less suitable for Nico who wants direct from your browser-to-provider BYOK rather than Glasp's hosted relay.

Strengths

No-signup flow for basic YouTube summaries — rare in this category.
Strong YouTube transcript handling.
Multiple model choices (ChatGPT, Claude, Gemini, Mistral) without managing provider keys.

Tradeoffs

YouTube-centered. Multi-source workflows need a second tool.
The Glasp ecosystem is broader than private local summary history, so privacy expectations should be checked before opting into the web app.
Reviewers report transcript-extraction failures on specific videos.

How to get started

Install YouTube Summary with ChatGPT & Claude from the Chrome Web Store.
Open a YouTube video.
Click the Glasp icon in the description area or open the side panel.
Pick model and summary style in the extension settings.
Optionally sign up for the Glasp web app to highlight and revisit summaries.

Pricing:Free for the core YouTube summary path with no account. The Glasp web app upsells highlighting, notes, and a learning workflow on top.

All-in-one learning assistant

NoteGPT

NoteGPT is a broad learning-and-summary workspace: YouTube summaries, article summaries, PDF chat, audio transcription, mind maps, and study materials in one account. Free tier exists with daily caps — typically a small number of PDFs per day and a per-file size limit. Paid tiers raise the caps.

Best for:Students and creators who want summaries plus transcription, notes, writing, visual, audio, and study tools in one account-centered workspace.

Best for Cleo turning lectures and study materials into reusable notes. Useful when the workflow is reading, studying, and exporting study artifacts — not just summarizing one source.

Strengths

Broad source coverage across YouTube, PDFs, documents, audio, images, slides, and text.
Learning-oriented extras such as mind maps, chat-with-PDF, translation, and generated study materials.
Useful when a web workspace fits the workflow better than an extension alone.

Tradeoffs

The broad workspace can be heavier than a focused summarizer.
Local-first storage and BYOK provider control are not the primary product posture.
Hard free-tier daily caps push users toward the paid tier quickly.

How to get started

Sign up at notegpt.io or install the Chrome extension.
Open a YouTube video, paste an article URL, or upload a PDF.
Choose summary style or generate a mind map.
Export to Markdown, PDF, or download notes.
Upgrade to premium to remove daily caps.

Pricing:Free tier with daily caps and file-size limits, plus a paid premium plan. Check current plan details on the NoteGPT site.

All-in-one browser side panel

Sider

Sider is a multi-model side-panel AI assistant covering chat, summarization, writing, translation, and PDF analysis. It supports many AI models through a side-panel workflow — useful when summary is one job among several. Sider is paid-mostly: the free tier is small and the paid tiers gate model variety.

Best for:Users who want summarization, chat, writing, translation, PDF analysis, image tools, and multi-model access in one browser assistant.

Fits a user who wants chat, writing, and summarization in one panel and is comfortable with a subscription. Less suitable for Nico when local-first storage or BYOK is a hard requirement.

Strengths

Broad browser assistant with webpage and YouTube summarization.
Supports many AI models through a single side-panel workflow.
Covers reading, writing, translation, PDF analysis, and image workflows.

Tradeoffs

Broader than a focused summarizer, which can be more UI and account surface than needed.
Summary history and provider-key locality are not positioned the same way as Reduz Bring your own AI key.
Verify the pricing tier and renewal terms before subscribing.

How to get started

Install Sider from the Chrome Web Store.
Sign in or create a Sider account.
Open the side panel via the toolbar icon or shortcut.
Pick the model and command (summary, chat, translate, etc.).
Upgrade to a paid tier to unlock model variety and higher quotas.

Pricing:Tiered subscription model from a low monthly entry price up to higher-tier plans. Verify current credit limits and renewal terms on the Sider site before committing.

Automation-heavy browser assistant

HARPA AI

HARPA AI is a browser-agent assistant with 100+ predefined commands for summarization, web automation, monitoring, price tracking, and content workflows. It supports multi-model routing across GPT, Claude, Gemini, DeepSeek, and OpenRouter, and is notable for being one of the few mainstream extensions where bringing your own AI key is part of the offering — though on a paid tier rather than as the default.

Best for:Power users who want page-aware commands, web automation, monitoring, and summaries from one Chrome extension.

Fits Nico when the workflow extends past summaries into web automation and monitoring. Heavier than needed if the job is just reading a source and saving a clean summary.

Strengths

Strong automation posture with many predefined page-aware commands.
Supports webpage, YouTube, file, and PDF summarization workflows.
BYOK is genuinely supported, even if gated behind the lifetime tier.

Tradeoffs

More complex than a dedicated summarizer.
Automation depth can be unnecessary if the job is only reading, saving, and exporting summaries.
BYOK is on the paid tier, not the default mode.

How to get started

Install HARPA AI from the Chrome Web Store.
Sign in and choose a connection: CloudGPT, ChatGPT web session, OpenAI API, OpenRouter, or others.
Open a page and trigger a command like /summary or /youtube-summary.
Use the chat panel or quick-access bar to chain commands.
Add a personal API key on the X-tier plan if you want BYOK routing.

Pricing:Tiered monthly subscriptions plus a one-time X-tier lifetime plan that supports bringing your own provider key. A free tier exists with usage caps.

Free web-tool directory

Noiz

Noiz is a free web-tool directory covering YouTube, PDF, article, webpage, book, document, and research-paper summarization surfaces. It leans into transparent retention copy — "files are deleted after summarizing" is part of the marketing. Useful when a packaged extension feels heavier than a one-off browser tool, and when the user wants an audit trail of which surface they used.

Best for:Users who want browser-accessible web tools for YouTube, PDFs, articles, research papers, text, and document summaries.

Good fit when a one-off web tool is preferred over an extension install. Less suitable for Anya who summarizes many sources a day and wants reusable history.

Strengths

Broad directory of task-specific AI tools across many source types.
Transparent retention copy (files deleted after summarizing).
No install required.

Tradeoffs

Less extension-first than Reduz — the workflow is "visit, paste, download" rather than working in the tab where the source lives.
No local history or export-to-Markdown system built in.
Each tool is a separate page rather than a unified workspace.

How to get started

Go to noiz.io and pick the tool that matches the source.
Paste the URL or upload the file.
Choose summary length or style.
Copy or download the result.
Return to the directory for a different source type.

Pricing:Free for the core summarizer surfaces. Some advanced flows may require account creation.

Other Eightify alternatives worth knowing

Smaller YouTube and multi-source summarizers that don't make the main list but solve specific gaps.

TubeOnAI
Cross-format summarizer covering YouTube plus PDFs, documents, audio, and video files. Useful if YouTube is one input among several but you want a smaller all-in-one.
Glarity
YouTube and Google-search summarizer using ChatGPT, Claude, or Gemini. Free with provider-side rate limits — usable as a free Eightify replacement for casual YouTube use.
Briefy
YouTube + webpage + PDF summarizer with visual outputs (mind maps, tables). 4.6 Chrome rating. Different visual style than Eightify.
Recapio
YouTube-focused summarizer with chapter breakdowns. Smaller install scale, decent for quick takeaways.
Merlin AI
26-in-1 AI extension covering YouTube summaries, writing, and chat. 4.8 Chrome rating. Reviewers note responses can feel "watered down" vs going to the native model provider.

When Eightify still wins, and when it doesn't

Eightify still wins when the entire workflow is YouTube-only, the user watches a small number of videos a day that fit the free tier, and the polished in-page panel matters more than provider control or multi-source coverage. Eightify loses when the free tier runs out faster than expected, when PDF / article / webpage summarization is also part of the job, when the user wants BYOK instead of a subscription, or when dark mode is a real requirement. Reduz is the most direct alternative — same in-tab YouTube workflow with timestamps, plus PDFs, articles, webpages, selected text, BYOK across five providers, 100 monthly hosted credits with no card, local history, and exports. Glasp YouTube Summary is the lightweight no-signup YouTube alternative. NoteGPT is the study-materials alternative. Sider and HARPA are heavier than Eightify by design — pick them only if summarization is part of a broader AI assistant workflow.

Frequently asked questions

What is the best Eightify alternative in 2026?

Reduz is the most direct alternative — same in-tab YouTube workflow with timestamps, plus PDFs, articles, webpages, selected text, BYOK across five providers, 100 monthly hosted credits with no card, local history, and DOCX/PDF/Markdown exports. Glasp YouTube Summary is the lightweight no-signup alternative for YouTube-only use.

Is there a free Eightify alternative that doesn't run out so quickly?

Glasp YouTube Summary is free with no sign-up for the basic flow. Reduz's Hosted Free tier includes 100 monthly credits with no card required. Reduz's bring your own AI key is unlimited because you pay your chosen provider directly — a heavy day of summarization on Claude Haiku 4.5 or GPT-5.4 Mini costs cents, well below Eightify's $9.99/month subscription.

Which Eightify alternative supports PDFs and articles?

Reduz, NoteGPT, Sider, HARPA AI, Monica, and Briefy all support PDFs and articles alongside YouTube. Reduz reads PDFs in-place from Chrome without uploading them, which is a meaningful difference from upload-based tools like NoteGPT and ChatPDF for users handling sensitive documents.

Can I use my own OpenAI or Claude API key instead of Eightify's hosted tier?

Eightify does not support BYOK at any tier — even the paid plan routes through their backend on ChatGPT and Claude. For BYOK YouTube summaries, Reduz makes BYOK the default mode across OpenAI, Anthropic Claude, Google Gemini, DeepSeek, and xAI Grok. HARPA AI supports BYOK on its lifetime tier.

Does Reduz work on YouTube the same way Eightify does?

The YouTube workflow is similar — open a video, click summarize, get bullets with timestamps. Reduz adds an injected button on the YouTube watch page (so you can summarize without opening the popup), supports YouTube Moments (timestamped key moments as a saved artifact), and stores the summary in local storage history so it survives closing the tab. Eightify's in-page panel polish is its main strength.

How do I cancel Eightify if I'm switching?

Cancellation is done through the Eightify account settings, App Store / Play Store subscription management (if you signed up on mobile), or Stripe customer portal depending on your signup path. Cancel before the renewal date to avoid the next billing cycle. This page is not affiliated with Eightify — check their support documentation for current cancellation steps.
