Synthiz vs Pocket: which alternative after the shutdown?

What each tool is for

Pocket, acquired by Mozilla, was for over ten years the reflex behind 'I'll read that later'. A button in the browser, a share from the phone, and the article joined a queue you could read offline in a stripped-back reading mode. Its strength was simplicity: one gesture, no filing required. The service shut down in 2025 and is no longer available; users were invited to export their data. So the comparison no longer happens in the present tense — the real question is where to go.

Synthiz does not take over that role exactly. It starts from the same gesture — a link you send it — but does not park it: it processes it. You give it an article, a YouTube video, a podcast or a PDF, or you subscribe to an RSS feed, a channel, a show, and syncing happens on its own (hourly, every six hours, or once a day). Anything audio or video is transcribed; a summary and its concepts are produced as soon as the source lands. Every statement carries timestamped citations that reopen the transcript at the exact second. Cross-source analysis shows what several sources say together, and Thoughts hold your own reflections, anchored to those sources.

Pocket stacked things up. Synthiz digests them.

What Pocket did better, and what you will miss

It is only fair to a tool that no longer exists but that many people still miss.

Pocket had a simplicity few have matched: one click, nothing to decide, no folder to pick, no mandatory tag. That absence of friction explains its mass adoption, and any tool asking for more at capture time loses something relative to it.

Its reading mode was excellent, with reliable offline support on mobile — a real point for anyone reading on a commute without signal. Its text-to-speech, while never brilliant, got the job done.

And it was free for ordinary use, which made it a standard. If your need was exactly that — set aside and read later, nothing more — what you are missing is a reading queue, not a synthesis engine. Instapaper and Raindrop.io are then more faithful replacements than Synthiz.

When to choose Synthiz

The right moment to change category rather than replace like for like is when the queue never emptied. For a lot of people, Pocket became a list of several hundred articles that were never reopened — a tidily filed regret. Reproducing that elsewhere solves nothing. Synthiz changes the promise: the source does not wait to be read, it arrives already summarised, with its concepts and its citations.

The second argument is format. Pocket only handled text. If your intake now includes podcasts and recorded talks, no reading queue will help: you need a transcript, and that is what Synthiz produces systematically.

The third is retrieval, and it is what separates a knowledge base from a pile of links. Finding, a year later, the article an idea came from when you have forgotten its exact wording is an exercise full-text search fails at regularly. Synthiz fuses a dense semantic score over bge-m3 embeddings with a lexical score, and decides relevance not with a fixed threshold but by how far a document sits from the distribution of its own query — mean + z*stddev, plus an absolute floor. On a measured corpus of 948 embeddings, a relevant query and a query matching nothing at all peaked just 0.09 apart: a fixed 0.65 cutoff returned nothing to a user who nonetheless owned five sources on the subject. So you find things without remembering the words, and a search with no match honestly answers zero results.

The fourth is the extension. Pocket had an excellent save button and Synthiz does not claim to reinvent that gesture: capture is one click too, on a web page, a YouTube video whose transcript is pulled automatically, or a podcast. What is added is search from the page you are on, with the excerpt shown around the term you searched for rather than a list of results — 'do I already know this?' settled without switching tabs.

Verdict by profile

Pocket user who misses the simplicity: Instapaper. It is the closest replacement for the original experience, sober and focused on reading.

User who collected more than they read: Synthiz. The problem was never the saving tool, it was that the reading never happened.

Intake that has become audio and video: Synthiz. No reading queue transcribes a podcast.

Need to organise links visually: Raindrop.io, closer to an enriched bookmark manager than to a reader.
