LinkDigest vs BibiGPT

BibiGPT is a consumer app and browser extension that summarizes a video link into key points and a transcript, with translation and export. LinkDigest is an API and MCP server that returns the whole post as structured text with a coverage receipt and checked quotes, priced per read. Dated comparison.

Competitor rows from their public docs on 2026-09-12; tell us if something changed. BibiGPT rows from bibigpt.co's product pages and docs as read on 2026-10-07; its plan prices are not quoted here because the public pricing page lists no per-call figures. LinkDigest rows are computed from the same constants as the pricing page and the coverage table. “—” means not stated in what we checked.

Feature	LinkDigest	BibiGPT
Xiaohongshu / Douyin	Yes — Xiaohongshu image and video notes; Douyin video and 图文 image notes.	Yes — Douyin and Xiaohongshu video summaries and transcripts, among 30+ platforms.
Other platforms	YouTube, TikTok, X, web pages. Instagram wired but not verified; Bilibili blocked (HTTP 412).	YouTube, Bilibili, TikTok, podcasts, local files and more.
OCR of images and frames	Yes — every image described and read for on-screen text; frames sampled from video.	Transcript-centred; image notes are not its focus.
Transcript (ASR)	Yes — native captions where a platform publishes them, otherwise Qwen3-ASR, in segments of up to ~170 s stamped with their start time.	Yes — a timestamped transcript with summary and translation.
Cookies or login from you	Xiaohongshu: no login, no cookies. Douyin runs on our session; you supply nothing.	An account on its site; the extension runs in your browser.
Search and comments	No — one post per link.	No search; the app summarizes a link you give it.
Batch	Yes — up to 50 links per call (POST /api/v1/digest/batch), duplicates merged, cached links free.	Per link, in the app.
Webhooks	Yes — a batch POSTs its summary to your URL when it finishes, HMAC-signed. Single links return a job id you poll.	No.
degraded field / receipt	Yes — a `degraded` array names what did not read fully. Plus `coverage` and a checked quote per key point.	No — a summary, without a statement of what was and was not read.
Failed reads free	Yes — a digest that read nothing is not charged.	Plan-based; not stated per call.
Cached links free	Yes — anything anyone already digested is free.	Not stated.
Price: a typical image note	1 credit ≈ $0.018 ($9 for 500 credits a month)	Not a per-call product; subscription tiers on its site.
Price: a 10-minute video	11 credits ≈ $0.198 (1 per started minute, plus the base credit)	Within a subscription's monthly allowance.
For agents (API / MCP)	REST API, MCP server, agent skills; a first look without a key.	An app and extension for people; an API is not its product.

Where BibiGPT is better

A finished product for a person: paste a link, read the summary, export it. Bilibili and local files included, which LinkDigest does not read.
Polished extras — illustrated articles, covers, translation on upload — aimed at creators.
Scale and trust: a 2023 product with a large user base.

Where LinkDigest is better

Built for the agent, not the person: JSON with transcript, on-screen text, per-image OCR, links and a receipt, over REST and MCP, with batch and webhooks.
Image notes read image by image — most of Xiaohongshu is pictures, not video.
A receipt and checked quotes: your agent can say what it read and what it did not, and back each point with the post's own words.
