YouTube Summarizer
Pros
- + No account, no OpenAI login, no API key — summaries generate straight from the YouTube page in my testing
- + Transcript with clickable timestamp navigation made verifying a summary claim against the video a one-click job
- + Summaries stayed faithful to the caption track and did not invent conclusions the speaker never made
- + Free with no visible quota or watermark; the developer states it is separate from the paid Syllaby platform
- + Unlimited summaries with no daily quota or credit system, unlike most competing free extensions that cap usage
Cons
- - Last store update was version 1.0.1 on March 19, 2024 — over two years of apparent inactivity at time of writing
- - No history or export: summaries live in a throwaway window and must be copied by hand
- - Entirely dependent on YouTube captions — videos without captions are unsummarizable and bad captions flow into the output
- - No chat-with-video, chapters, batch mode, or output-language options; English-only listing
Runway ML
Pros
- + Aleph 2.0 edits footage you already have — I produced three campaign variants from one hero shot by changing background and product while the performance held
- + Deepest toolchain in the category: generation, workflows, canvas, Act-Two performance capture, ProRes/PNG export, and a documented API
- + Credit math is transparent: 12 credits/second for Gen-4.5 published, top-ups flat at $0.01 each with 1,000 minimum and no expiry
- + Honest help-center language — Runway itself calls Standard 'light, exploratory usage', which matched my measured yield of 3–4 usable shots/month
- + Strong institutional footing: founded 2018, ~$1.05B raised, $5.3B valuation (Feb 2026), Runway Studios and an AI film festival for ecosystem gravity
Cons
- - Expensive per finished second — Standard's 625 credits buy ~52s of Gen-4.5 before retries, so Pro ($28/mo annual) is the practical floor
- - Flagship generation is capped at 720p in-app while Aleph edits at 1080p; resolution runs backwards through the workflow
- - No native long-form generation (2–10s Gen-4.5 clips) — narrative sequences need external assembly
- - The Unlimited plan stopped selling on 1 June 2026 and its Unlimited/Explore Mode replacement excludes Gen-4.5 and covers a model list Runway says may change
- - Queues are noticeably slower at peak on lower tiers; priority is effectively a paid feature
